Whenever I have a holiday ham in the refrigerator, I know exactly what happens next. The first round of leftovers goes into sandwiches, somebody grabs a few slices straight from the fridge, and then I’m left staring at a container of diced ham wondering how I can turn it into an actual dinner. That is where ham casseroles earn their place in my kitchen. Cooked ham already brings plenty of savory flavor, so it doesn’t take much to turn it into something completely different. Potatoes, pasta, rice, eggs, vegetables, and a good cheese sauce can take those leftovers from “holiday food again” to the kind of bubbling casserole everyone wants a second helping of.
For this list, I wanted to stick with ham casserole recipes that actually make sense for leftovers. These are familiar combinations built around dishes home cooks already make: scalloped potatoes and ham, cheesy noodles, broccoli and rice, breakfast bakes, hash brown casseroles, macaroni and cheese, and creamy pasta casseroles. I’ve included a few different directions so every pan doesn’t taste identical, but I haven’t pushed the list into strange territory just for the sake of having 25 ideas. If I have two or three cups of leftover ham after Easter, Christmas, or Sunday dinner, these are exactly the kinds of casseroles I want waiting in my recipe box.
1. Cheesy Ham and Potato Casserole
This is probably the first casserole I think about when somebody says they have leftover ham. Potatoes are mild enough to take on all that smoky, salty ham flavor, while a creamy cheddar sauce ties everything together. I like using diced cooked ham rather than large pieces because it spreads through the potatoes better, giving me a little ham in nearly every serving. Onion, black pepper, sharp cheddar, and a simple milk-based sauce are really all this casserole needs.
What makes this one especially useful after a holiday is that it doesn’t feel like I’m simply reheating yesterday’s dinner. Once the ham is tucked between tender potatoes and covered in bubbling cheese, it becomes its own comfort-food meal. I usually let the casserole rest for several minutes after baking because the sauce thickens as it sits. Add steamed green beans, roasted broccoli, or a simple salad, and I have an easy dinner that can use a surprisingly generous amount of leftover ham.
2. Scalloped Potatoes and Ham
Scalloped potatoes and ham are slightly different from the chunky potato casserole above, and I think both deserve a spot. Here I want thin, overlapping potato slices surrounded by a silky cream sauce with pieces of ham tucked between the layers. Onion is especially good in this casserole because it melts into the sauce while everything bakes. The finished dish should be creamy rather than soupy, with potatoes that are completely tender when I slide a knife through the center.
This is one of those old-fashioned leftover recipes that has stayed popular because the combination simply works. Ham provides enough savory flavor to transform what might normally be a side dish into a satisfying main course. I can finish it with cheddar, Gruyère, Parmesan, or leave the sauce mostly creamy if I want something closer to traditional scalloped potatoes. Either way, it is an excellent choice when I have several cups of holiday ham and need a substantial family dinner.
3. Creamy Ham and Noodle Casserole
Ham and noodles are another combination I come back to because they make leftover meat stretch without making dinner feel skimpy. Egg noodles are my favorite here because their broad shape holds creamy sauce especially well. I combine them with diced ham, a creamy sauce, peas, onion, and enough cheese to make the casserole rich without burying everything underneath it. A little Dijon mustard or black pepper helps cut through the richness.
I also like giving this casserole a crisp topping because the contrast makes a big difference. Buttered breadcrumbs are the classic choice, although crushed crackers work when that is what I have in the pantry. Underneath, the noodles stay soft and creamy while the ham and peas provide little pockets of savory and sweet flavor. It is simple family food, and that is exactly why I think it works so well for the busy days immediately after a big holiday.
4. Ham, Broccoli, and Cheese Casserole
Broccoli and cheese already belong together, and adding leftover ham turns that familiar pairing into dinner. I like keeping the broccoli pieces fairly substantial rather than chopping them until they disappear. They soften in the oven but still provide texture against the creamy cheese sauce and tender ham. Sharp cheddar is an easy choice because it has enough personality to stand up to both ingredients.
The biggest thing I watch with this casserole is moisture. Frozen broccoli can release quite a bit of water, so I thaw and drain it well before it goes into the baking dish. That little step keeps the cheese sauce creamy instead of watery. I’ll sometimes add cooked rice or pasta when I want to stretch the casserole further, but the basic ham-broccoli-cheddar combination is filling enough to stand on its own with bread or a salad.
5. Ham and Rice Casserole
When I have cooked rice hanging around along with the ham, I can clear two containers from the refrigerator with one casserole. Rice absorbs sauce and flavor beautifully, which makes it a natural base for diced ham. I like adding onion, celery or peas for some texture, then bringing everything together with a creamy sauce and cheddar. The result is simple, cozy, and much more interesting than serving plain reheated rice next to slices of ham.
This is also an easy casserole to adjust according to how much ham I actually have. A smaller amount can be spread through plenty of rice and vegetables, while a ham-heavy version feels richer and more substantial. I keep the seasonings fairly restrained because cooked ham and cheese both bring salt to the dish already. Black pepper, garlic, parsley, or a small spoonful of Dijon usually gives me all the extra flavor I need.
6. Ham and Hash Brown Casserole
Frozen hash browns make this one particularly convenient when I’m tired of cooking after hosting a holiday meal. I combine them with diced ham, cheese, onion, and a creamy base, then bake everything until the potatoes are tender and the top develops those irresistible browned edges. Shredded hash browns make a softer casserole, while diced Southern-style potatoes give me more obvious potato texture.
I think of this as one of those casseroles that can move easily between breakfast and dinner. Add eggs and it becomes a full breakfast bake; leave the eggs out and it works more like cheesy potatoes with ham. Either version is practical when I need to feed several people without doing much active cooking. A sprinkle of green onion over the finished pan gives it freshness and makes the rich potato-and-cheese combination feel a little lighter.
7. Ham and Cheese Breakfast Casserole
If I have leftover ham and a loaf of bread that needs using, a classic egg casserole solves both problems. Cubed bread absorbs a mixture of eggs and milk while diced ham and shredded cheese settle throughout the pan. I usually add onion or green onion, and bell pepper is useful when I want another vegetable without changing the familiar breakfast flavor.
The real advantage is being able to assemble the casserole ahead. I can put it together in the evening, refrigerate it, and bake it the following morning when everyone is hungry again. The bread becomes tender and custardy inside while the top gets golden around the edges. It is especially useful after Christmas or Easter because I can turn dinner leftovers into brunch without making another elaborate meal from scratch.
8. Ham and Cheese Croissant Casserole
Croissants make an egg casserole noticeably richer than ordinary sandwich bread. I tear or cut them into chunks, layer them with diced ham and cheese, and pour an egg-and-milk mixture over the top. Swiss cheese is especially good here because that ham-and-Swiss combination already feels familiar, but cheddar or Gruyère can work just as easily.
This is the casserole I’d choose when leftover ham needs to become a brunch dish that feels a little more special. The croissant pieces soak up the custard while keeping some buttery texture around the top, so I get crisp edges and a soft center in the same scoop. It looks impressive enough for company, but the preparation is still basically layering, pouring, refrigerating, and baking.
9. Ham Tetrazzini
Tetrazzini is usually associated with turkey or chicken, but ham works remarkably well in the same creamy pasta format. I like spaghetti or linguine mixed with diced ham, mushrooms, Parmesan, and a creamy sauce. Peas fit naturally here too, especially because their sweetness balances salty ham. Everything gets transferred to a baking dish and cooked until the sauce is hot and the top has started to brown.
What keeps this from tasting like a basic ham noodle casserole is the mushroom-and-Parmesan direction. It has a slightly deeper, more savory flavor, and long pasta gives the casserole a different texture. I would use this when I have a decent amount of ham but want dinner to feel more like pasta night than leftover night. Garlic bread and a green salad are about all I need alongside it.
10. Ham Mac and Cheese Casserole
Macaroni and cheese is one of the easiest dishes to turn into a leftover ham dinner. I start with elbow macaroni and a smooth cheddar sauce, then fold diced ham through before everything goes into the baking dish. The ham gives the pasta a smoky, savory bite without taking away from what people love about classic mac and cheese.
For the top, I prefer breadcrumbs tossed with a little melted butter and Parmesan. That creates a crisp layer over all the creamy pasta underneath. Peas or broccoli can be added if I want vegetables in the same pan, but I don’t think they are essential. Sometimes the simplest version—ham, macaroni, cheddar sauce, and crunchy crumbs—is exactly what everybody wants.
11. Ham, Broccoli, and Rice Casserole
This is the kind of complete casserole I appreciate on a weeknight because the protein, vegetable, and starch are already in the baking dish. Cooked rice forms the base, broccoli adds color and texture, and leftover ham gives the whole thing its savory backbone. I use cheddar in the sauce because broccoli and cheddar are such a dependable combination.
I prefer this one when I only have a moderate amount of ham left. Rice and broccoli add enough volume that even a cup or two of diced meat can flavor a full casserole. The trick is keeping enough sauce in the mixture so the rice doesn’t dry out in the oven. Once everything is creamy and topped with a little extra cheese, it only needs enough baking time to become hot, bubbly, and lightly golden.
12. Ham and Pea Pasta Casserole
Ham and peas are one of those combinations that show up again and again because the flavors balance each other so naturally. I use short pasta such as penne, shells, or rotini and mix it with diced ham, peas, and a creamy cheese sauce. Shells are particularly good because little pieces of ham and peas find their way into the pasta.
A touch of Parmesan and black pepper keeps this casserole from becoming bland, while a little Dijon can add gentle sharpness. I don’t overload it with seasonings because the whole point is an easy leftover dinner built from ingredients I probably already have. It is also a good option for kids who may not be interested in a casserole loaded with lots of unfamiliar vegetables.
13. Ham and Asparagus Casserole
Asparagus makes a lot of sense with leftover Easter ham, particularly when spring produce is at its best. I cut the asparagus into manageable pieces and combine it with ham, pasta or rice, and a creamy sauce. Swiss, cheddar, or Parmesan all work, although I like Swiss when I want the ham flavor to stay prominent.
I’m careful not to overcook the asparagus before the casserole goes into the oven. It still has baking time ahead of it, and I would rather have tender pieces with some shape than soft green pieces disappearing into the sauce. This casserole feels fresher than the heavier potato versions, making it one of my favorite ways to transition holiday leftovers into a regular weeknight dinner.
14. Ham and Cheddar Pierogi Casserole
Pierogies give leftover ham a different base without taking the casserole into strange territory. Potato-filled pierogies already work naturally with cheddar, onions, and sour cream, so adding diced ham feels like an obvious extension. I arrange the pierogies in the baking dish, surround them with ham and a creamy cheddar sauce, then bake until everything is hot.
Green onions are especially good over the top because they cut through all those rich potato-and-cheese flavors. I also like this recipe because there is no separate pot of pasta or rice to cook. Using frozen pierogies makes it surprisingly manageable for a weeknight, yet the finished casserole is substantial enough that I only need a vegetable or salad beside it.
15. Ham and Swiss Pasta Bake
Ham and Swiss is familiar from sandwiches, quiche, and cordon bleu, so it translates easily to baked pasta. I use penne, rotini, or shells and combine the pasta with diced ham and a creamy Swiss cheese sauce. A little Dijon mustard is particularly useful here because it reinforces that classic ham-and-Swiss flavor without turning the casserole into something complicated.
This is a good alternative when I’ve already made one or two cheddar-heavy leftover dishes. Swiss has a nuttier flavor and makes the casserole feel genuinely different even though the method is just as easy. I like breadcrumbs over the top for texture, and I sometimes mix Parmesan into them so the crust gets especially savory as it browns.
16. Ham and Cauliflower Cheese Casserole
Cauliflower cheese becomes a main dish once leftover ham gets involved. I use cauliflower florets that are just barely tender and coat them in a cheddar or cheddar-Parmesan sauce with plenty of diced ham. It gives me the comforting character of a cheesy casserole while keeping the vegetable much more noticeable than it would be in a pasta-heavy recipe.
This one is especially useful when I’ve had several days of holiday potatoes, rolls, and desserts and want dinner to lean a little more toward vegetables without pretending I suddenly want salad for supper. The ham still makes the dish hearty, and the browned cheese on top keeps it firmly in comfort-food territory. A little mustard powder or Dijon is all the extra seasoning I usually add.
17. Ham and Potato Au Gratin
For this version, I lean harder into cheese than I do with traditional scalloped potatoes. Thin potato slices, diced or chopped ham, cream sauce, and plenty of cheese are layered in the baking dish so the potatoes absorb flavor as they soften. Gruyère is excellent, but cheddar is easier to find and still makes a deeply satisfying casserole.
The golden top is what separates a good gratin from a merely creamy potato bake for me. I want those browned cheese spots and slightly crisp edges around the dish. Since potatoes take time to become completely tender, I slice them evenly and resist rushing the bake. The finished casserole is rich enough to serve as the main event rather than a side.
18. Ham and Mushroom Egg Casserole
Mushrooms add savory depth to leftover ham without introducing a flavor that feels out of place. I sauté the mushrooms first so they lose excess moisture and develop some browning, then combine them with diced ham, eggs, cheese, and a little onion. Swiss cheese fits particularly well, although cheddar is perfectly dependable.
This is a nice option when I want a breakfast casserole without a large amount of bread or potatoes. The texture stays more egg-forward, almost somewhere between a crustless quiche and a traditional breakfast bake. I’ll serve it with toast and fruit for brunch, but it is just as useful for an easy breakfast-for-dinner night.
19. Ham and Corn Casserole
Corn’s natural sweetness is surprisingly good against smoky, salty ham. I like a casserole that combines corn kernels with diced ham, eggs, dairy, and either a cornbread-style base or a soft corn-pudding texture. Cheddar can be included, but I keep it moderate so the corn remains an important part of the dish rather than becoming another generic cheese casserole.
This is especially handy when my holiday refrigerator contains leftover ham but the pantry is doing most of the remaining work. Frozen or canned corn makes it possible year-round, and the casserole goes well with a simple green vegetable. It is also different enough from potatoes and pasta to keep the leftover-ham stretch from feeling repetitive.
20. Ham and Spinach Pasta Casserole
Spinach gives a creamy ham pasta casserole plenty of color without requiring much extra preparation. I use short pasta, diced ham, wilted spinach, and a creamy cheese sauce, usually with Parmesan plus mozzarella or cheddar. Garlic works particularly well in this version and gives the sauce more personality.
I make sure to squeeze excess moisture from frozen spinach before adding it. That prevents the casserole from becoming watery and helps the sauce cling to the pasta. The spinach also stretches a smaller amount of ham through the whole dish, which is useful when I’m down to the final container and still want enough dinner for the family.
21. Ham and Potato Breakfast Casserole
Instead of shredded hash browns, this casserole uses diced potatoes for a chunkier breakfast bake. I combine cooked or partially cooked potatoes with ham, eggs, cheese, and onion, then add bell peppers when I have them. The result reminds me of a skillet breakfast, only everything is baked together in one pan.
I particularly like this approach when I have leftover roasted or boiled potatoes from the same holiday meal as the ham. It turns two leftovers into something new and saves prep at the same time. The potatoes give the casserole enough substance for dinner too, so I don’t reserve this one strictly for breakfast.
22. Ham, Cheese, and Biscuit Casserole
Biscuits make an easy base for a hearty ham breakfast casserole. Depending on the recipe style, I can layer biscuit pieces with ham, eggs, and cheddar or place biscuits over a creamy ham filling. For a true breakfast bake, I prefer the first version because the biscuit pieces absorb some egg mixture while still getting browned around the exposed edges.
This casserole is unapologetically filling, which makes it useful for a family brunch or a morning when people will be coming back to the kitchen at different times. Ham is already seasoned and cooked, so most of the work is simply assembling everything. I like green onions or a little parsley over the finished pan to add freshness before serving.
23. Chicken Cordon Bleu Casserole with Leftover Ham
Chicken cordon bleu casserole is one of the few mixed-meat casseroles I think genuinely belongs on a leftover-ham list. Ham, chicken, Swiss cheese, and a creamy sauce reproduce the familiar cordon bleu combination without all the rolling and breading of individual chicken breasts. If I have leftover cooked chicken too, this becomes particularly practical.
Some versions use pasta or rice underneath, while others keep the focus on chicken and ham and finish with breadcrumbs. I prefer a crisp crumb topping because traditional cordon bleu has a breaded exterior, and that crunch gives a similar effect. It is richer than several casseroles on this list, so a sharp green salad or roasted vegetables make the best sides.
24. Ham and Tortellini Casserole
Cheese tortellini gives me both pasta and a cheesy filling in one ingredient, making it an easy partner for leftover ham. I combine cooked tortellini with diced ham, peas or broccoli, and a creamy sauce, then finish the dish with Parmesan before baking. Because the pasta itself is rich, I don’t think this casserole needs an excessively heavy sauce.
This is the sort of recipe I save for the last round of holiday leftovers because it feels completely removed from the original ham dinner. Nobody is looking at the plate thinking they are eating the same meal for the fourth time. Instead, it tastes like a creamy baked pasta dinner where ham happens to be one of the best ingredients.
25. Ham and Vegetable Pasta Bake
My final casserole is the flexible one I use when the refrigerator needs clearing out. Short pasta, diced leftover ham, broccoli, peas, carrots, spinach, or asparagus can all find a place here, as long as I choose vegetables that make sense together. I bring everything together with a light creamy cheese sauce and finish the top with cheddar, Parmesan, or breadcrumbs.
I still try to keep this casserole intentional instead of treating it like a dumping ground for every leftover in the refrigerator. Ham plus two or three compatible vegetables is usually enough. The finished bake should still have a clear creamy-ham-and-pasta identity. When I keep that balance, it becomes one of the most practical ways I know to turn the final scraps of a holiday meal into a family dinner everyone will actually want.
FAQs About Leftover Ham Casseroles
What casseroles can I make with leftover ham?
Some of my most dependable options are ham and potato casserole, scalloped potatoes with ham, ham noodle casserole, ham and broccoli casserole, ham and rice casserole, ham mac and cheese, breakfast casserole, hash brown casserole, and ham pasta bakes. Ham works especially well with potatoes, eggs, rice, pasta, broccoli, peas, asparagus, Swiss cheese, and cheddar.
How much leftover ham should I put in a casserole?
For most family-size casseroles, I find that roughly 1½ to 2 cups of diced cooked ham is enough to give the dish plenty of ham flavor. A casserole based heavily on potatoes, pasta, or rice can handle more. If I only have about a cup left, I choose a recipe with vegetables, eggs, rice, or pasta so that smaller amount can stretch across several servings.
Do I need to cook leftover ham before adding it to a casserole?
No. Holiday ham and other fully cooked ham have already been cooked, so I’m mainly reheating the ham while the rest of the casserole cooks. I dice or chop it into relatively small pieces so it heats evenly and distributes throughout the dish.
How do I keep a ham casserole from becoming too salty?
I season the rest of the casserole carefully. Ham can already be salty, and ingredients such as cheddar, Swiss, Parmesan, canned soup, and packaged sauces can add even more sodium. I normally wait until the sauce is assembled before deciding whether it needs additional salt. Black pepper, garlic, herbs, Dijon mustard, onion, and fresh vegetables can add flavor without relying entirely on salt.
Why is my ham casserole watery?
Extra moisture often comes from frozen vegetables, insufficiently thickened sauce, or vegetables that release water while baking. I drain thawed broccoli and spinach thoroughly and make sure a homemade cream sauce has thickened before combining it with the casserole. Potato casseroles also benefit from resting after baking because the sauce continues to thicken as the dish cools slightly.
Can I use spiral ham in these casseroles?
Absolutely. Spiral-cut holiday ham is one of my favorite leftovers to use because it is already easy to chop. I remove any overly thick pieces of exterior glaze when necessary, especially if the glaze is very sweet, and dice the rest into bite-size pieces.
What cheese tastes best with leftover ham?
Cheddar and Swiss are the two I use most often. Sharp cheddar is excellent with potatoes, broccoli, macaroni, rice, and eggs, while Swiss works particularly well in ham-and-cheese breakfast casseroles, pasta bakes, and cordon bleu casseroles. Gruyère, Parmesan, mozzarella, and Monterey Jack can also work depending on the recipe.
What vegetables go well in ham casserole?
Broccoli, peas, asparagus, spinach, mushrooms, cauliflower, corn, bell peppers, onions, and carrots are all sensible choices. I choose vegetables according to the casserole rather than trying to squeeze several unrelated ones into the same pan. Broccoli with cheddar, peas with creamy pasta, asparagus with ham and Swiss, and mushrooms with eggs are combinations I use repeatedly.
Can I prepare a ham casserole ahead of time?
Many ham casseroles are excellent make-ahead meals. Breakfast casseroles in particular are often better suited to overnight refrigeration because the bread has time to absorb the egg mixture. Pasta, rice, and potato casseroles can frequently be assembled ahead as well, although the exact timing depends on the sauce and whether the starch is already cooked.
Can leftover ham casserole be frozen?
Many can, particularly pasta, rice, potato, and breakfast casseroles. I cool the casserole completely before wrapping it for the freezer. Cream sauces and potatoes can occasionally change texture after freezing, so if freezer quality is important, I prefer casseroles with pasta or rice and plenty of sauce.
What should I serve with ham casserole?
Because most ham casseroles are rich and filling, I keep the sides uncomplicated. Roasted asparagus, green beans, steamed broccoli, Brussels sprouts, a crisp green salad, glazed carrots, or simple roasted vegetables are usually enough. With breakfast casseroles, I’ll add fruit or a light salad rather than another heavy side.
What is the easiest leftover ham casserole?
For me, a hash brown casserole is difficult to beat for convenience. Frozen potatoes eliminate most of the prep, and cooked ham is already ready to go. Ham mac and cheese and simple ham noodle casserole are close behind, particularly if I have cooked pasta or a prepared cheese sauce available.
Final Thoughts
I think leftover ham is one of those ingredients that becomes more useful once I stop trying to recreate the original holiday plate. Instead of reheating another slice beside mashed potatoes, I’d rather dice it and let it become part of a completely different meal. That is why casseroles work so well. A relatively small amount of cooked ham can flavor an entire dish of potatoes, noodles, rice, vegetables, or eggs, and most of the combinations rely on familiar ingredients rather than anything difficult to find.
If I had to narrow these 25 down to the recipes I’d make first, I would start with cheesy ham and potato casserole for classic comfort food, ham and noodle casserole for an easy family dinner, broccoli and cheese casserole when I want more vegetables, and ham and cheese breakfast casserole for the morning after a holiday. Scalloped potatoes and ham will always be one of the best old-school options too. The important part is that leftover ham shouldn’t feel like an obligation. Put it into the right casserole, add a bubbling sauce and a browned top, and suddenly those leftovers are the reason dinner is already halfway figured out.
