Christmas meals have a way of turning into a lot of moving parts. There’s breakfast to think about, a holiday dinner to pull together, and someone asking for a snack while you’re still peeling potatoes.
That’s where a good casserole earns its spot on the menu. One baking dish can hold a cozy breakfast, a hearty main course, or the side dish everyone hopes you made again this year.
These holiday casserole recipes for Christmas cover all three, with sweet breakfast bakes, cheesy vegetable sides, and comforting dinners for the busy days around the holiday. Pick a few that fit your family’s tastes and your oven schedule—you don’t need to make the whole menu from scratch to serve a meal that feels special.
Christmas Breakfast Casseroles
1. Sausage, Egg, and Cheddar Breakfast Casserole
A savory sausage and egg casserole is a welcome breakfast when Christmas morning starts early. Cubed bread soaks up the egg mixture, while browned breakfast sausage and sharp cheddar make each square hearty enough to carry everyone through a morning of opening presents.
Use slightly stale bread so the finished casserole holds its shape. A little Dijon mustard in the egg mixture adds flavor without making the whole dish taste like mustard.
Holiday prep tip: Brown and drain the sausage ahead of time. For an overnight version, use a recipe designed for a refrigerated rest so the bread and custard proportions work together.
2. Cranberry Orange French Toast Casserole
Tart cranberries, orange zest, and soft bread make a French toast bake that feels especially right for Christmas brunch. The top turns golden while the middle stays soft and custardy.
Brioche or challah works beautifully here. Finish with a light dusting of powdered sugar and serve maple syrup on the side so guests can choose how sweet they want their breakfast.
Serve it with: Plain Greek yogurt and a bowl of fresh fruit to balance the rich bread.
3. Ham and Cheese Croissant Casserole
Torn croissants give this breakfast casserole buttery layers and crisp edges. Add diced cooked ham, Swiss cheese, and an egg custard for a dish that feels a little fancy without requiring individual breakfast orders.
Tuck some croissant tips above the custard so they can brown. A sprinkle of chives adds a fresh finishing touch.
Holiday prep tip: Chop the ham and shred the cheese the day before, then keep them refrigerated until you’re ready to assemble.
4. Cinnamon Roll Casserole
Cinnamon roll casserole brings the cozy cinnamon flavor kids love to a breakfast bake that’s easy to portion. Pieces of cinnamon roll dough bake together with an egg mixture, creating a soft center and golden edges.
Use a recipe developed for your particular type of cinnamon rolls, since dough sizes and baking times vary. Let the casserole settle briefly before drizzling on the icing.
Serve it with: Scrambled eggs or a savory breakfast meat for a sweet-and-savory brunch.
5. Spinach, Mushroom, and Feta Egg Bake
For a breakfast option without bread or potatoes, try an egg bake filled with sautéed mushrooms, spinach, and crumbled feta. It’s colorful, savory, and easy to serve beside richer brunch dishes.
Cook the mushrooms until their released moisture evaporates, and squeeze thawed spinach well if you’re using frozen. Both steps help prevent a watery casserole.
Make it festive: Add a few halved cherry tomatoes for little pops of red.
6. Cheesy Hash Brown Breakfast Casserole
Shredded hash browns, eggs, cheddar, and cooked breakfast sausage make a hearty Christmas breakfast. The potatoes give it a familiar, comforting texture that works well for a mixed crowd.
Thaw frozen hash browns and remove excess moisture before assembling. Diced red bell pepper and green onion add color without making the casserole complicated.
Family-friendly variation: Leave the peppers out of one portion if you have a child who prefers a simpler breakfast.
7. Gingerbread Baked Oatmeal Casserole
Gingerbread baked oatmeal offers a cozy alternative to a pastry-heavy breakfast table. Molasses, cinnamon, ginger, and a little nutmeg give the oats their holiday flavor.
Bake until the center is set, then serve warm with milk or yogurt. Chopped pears make a lovely topping, and toasted pecans can be offered separately.
Why it works for Christmas: It’s easy to portion, doesn’t need last-minute flipping, and pairs nicely with coffee while everyone settles into the morning.
Christmas Side Dish Casseroles
8. Classic Green Bean Casserole
Green bean casserole belongs on this list for its creamy sauce and crunchy fried-onion topping. It’s familiar, easy to recognize on a crowded table, and especially good beside roast turkey or ham.
You can use a traditional condensed-soup version or a homemade mushroom sauce. Whichever route you choose, drain the green beans well so the sauce stays creamy.
Holiday prep tip: Keep the crispy onion topping separate until the stage specified in your recipe so it doesn’t soften before serving.
9. Sweet Potato Casserole with Pecan Streusel
Smooth sweet potatoes and a buttery pecan topping bring a little sweetness to a savory Christmas plate. Cinnamon and vanilla complement the potatoes without needing an overly sugary filling.
Bake or roast the sweet potatoes first for a concentrated flavor. Spread the mash evenly before adding the topping so every scoop gets a little crunch.
Serve it with: Glazed ham, turkey, or a savory mushroom main.
10. Marshmallow Sweet Potato Casserole
If your family waits all year for the marshmallow version, Christmas dinner is a good time to bring it out. A soft sweet potato base and toasted marshmallows make it feel like a holiday tradition all on its own.
Keep the filling moderately sweet, since the topping already adds plenty. Add the marshmallows near the end of baking and watch closely as they brown.
Family-friendly idea: Use a shallow dish for a higher topping-to-filling ratio.
11. Creamy Scalloped Potato Casserole
Thinly sliced potatoes baked in a creamy sauce make a beautiful side for Christmas ham. Garlic, onion, and thyme add enough flavor to keep the dish interesting without competing with the main course.
Slice the potatoes evenly so they cook at the same rate. Test the center with a knife before taking the casserole out; a golden top doesn’t always mean the potatoes underneath are tender.
Planning tip: This dish needs a generous oven window, so work backward from dinner time.
12. Cheesy Broccoli Rice Casserole
Broccoli, cooked rice, and a creamy cheddar sauce make a comforting side that also helps stretch a holiday meal. A crisp breadcrumb topping gives the soft filling some welcome texture.
Keep the broccoli slightly firm before baking so it doesn’t turn mushy. Freshly shredded cheddar melts smoothly into a homemade sauce.
Easy variation: Add cooked chicken to turn it into a separate family dinner during Christmas week.
13. Corn Casserole
Corn casserole sits somewhere between a soft cornbread and a spoonable side dish. Corn kernels add texture, while creamed corn helps give it that tender, moist middle.
It’s a good choice when your menu already includes potatoes and you want something different. Bake until the center is set according to your recipe rather than relying only on the color around the edges.
Serve it with: Ham, green beans, and a crisp winter salad.
14. Brussels Sprout Gratin
Brussels sprouts get the holiday treatment with a creamy sauce, Gruyère, and a golden breadcrumb topping. Halving the sprouts makes them easier to eat and helps the sauce settle between the layers.
Roast or briefly cook the sprouts before assembling, depending on your recipe. Adding them raw to an untested bake can leave you with tough centers and an overbrowned top.
Optional extra: Scatter cooked bacon over the casserole for a smoky finish.
15. Butternut Squash and Sage Gratin
Butternut squash, sage, and Parmesan make a warm, savory side with a little natural sweetness. It’s a lovely option when you want a holiday vegetable dish that doesn’t feel like another version of potatoes.
Use evenly sized squash pieces or thin slices, following the method in your chosen recipe. A light breadcrumb topping adds crunch.
Holiday pairing: Serve beside roast chicken, turkey, or a pork roast.
16. Cauliflower Cheese Casserole
A creamy cheese sauce turns cauliflower into a comforting Christmas side. Sharp cheddar brings plenty of flavor, and a little mustard adds depth to the sauce.
Steam or blanch the florets until just tender, then drain them thoroughly before assembling. Too much leftover water can thin the cheese sauce.
Serving tip: Use a wide baking dish so there’s plenty of golden topping to go around.
17. Loaded Mashed Potato Casserole
Mashed potatoes baked with cheddar, sour cream, cooked bacon, and green onions are made for a generous holiday table. The top becomes lightly golden while the middle stays soft and creamy.
Start with smooth mashed potatoes and add enough moisture to account for the extra oven time. Save some cheese and green onion for the top.
Family-friendly variation: Serve the bacon and onions separately if some guests prefer plain cheesy potatoes.
18. Creamed Spinach Casserole
Creamed spinach casserole is rich, savory, and a good match for roast beef or turkey. Parmesan, garlic, and a small pinch of nutmeg give the filling plenty of flavor.
Frozen spinach is convenient here, but squeezing it dry is essential. A topping of buttered breadcrumbs adds texture to the creamy base.
Menu tip: Choose this or another creamy vegetable casserole, then add a simpler roasted vegetable for variety.
Christmas Dinner and Leftover Casseroles
19. Turkey and Stuffing Casserole
Turkey and stuffing casserole brings familiar Christmas dinner flavors together in one dish. Cooked turkey sits in a creamy filling beneath a layer of stuffing that turns crisp around the edges.
Add cooked vegetables such as carrots, peas, or green beans to make it a fuller meal. Keep the filling moist enough that the turkey stays tender during baking.
Best for: A relaxed dinner after the main celebration, especially when you already have cooked turkey to use.
20. Ham and Potato Casserole
Diced cooked ham, tender potatoes, and a creamy cheese sauce make a satisfying dinner for Christmas week. It’s especially useful when you want to turn extra ham into something different.
Use a recipe that clearly specifies cooked or raw potatoes; the two need different amounts of liquid and oven time. Taste the sauce before adding much salt because ham and cheese contribute their own.
Serve it with: A green salad or steamed green beans.
21. Chicken, Wild Rice, and Mushroom Casserole
Chicken and wild rice casserole feels cozy enough for Christmas Eve without requiring a formal roast. Mushrooms, celery, and thyme give it a savory flavor that fits the season.
Cook the rice according to the recipe before combining it with the filling. Wild rice blends vary, so follow the package directions if your recipe calls for already-cooked rice.
Practical shortcut: Use cooked rotisserie chicken to reduce the prep work.
22. Christmas Eve Lasagna
Lasagna is a practical Christmas Eve dinner when you want one main dish that can feed several people. Layers of pasta, meat sauce, ricotta, and mozzarella make it filling enough to serve with just a salad and bread.
Let it rest before slicing so the layers hold together. A little chopped parsley or basil adds a fresh green finish.
Planning tip: If assembling ahead, follow your recipe’s refrigeration and baking directions, including any extra time needed for a chilled dish.
23. Spinach and Ricotta Stuffed Shells Casserole
Stuffed shells make a pretty meatless main for the holiday table. The creamy spinach-ricotta filling sits inside large pasta shells, with red marinara underneath and melted mozzarella on top.
Cook a few extra shells because some may tear while boiling. A piping bag or a food-storage bag with one corner snipped off makes filling them less messy.
Serve it with: Roasted vegetables and garlic bread for a complete dinner.
24. Shepherd’s Pie Casserole
A savory lamb filling topped with mashed potatoes makes shepherd’s pie a cozy choice for a quiet Christmas Eve dinner. Ground beef works too; that version is traditionally called cottage pie.
Carrots, peas, onion, and a rich gravy give the filling its comforting flavor. Drag a fork across the potato topping to create ridges that brown in the oven.
Holiday touch: Stir roasted garlic into the mashed potatoes for extra flavor.
25. Cranberry Turkey and Sweet Potato Casserole
For a Christmas leftover bake with a different flavor, layer cooked turkey and vegetables in a savory gravy, then top with mashed sweet potatoes. Small spoonfuls of cranberry sauce add a tart contrast.
Keep the cranberry sauce in little pockets rather than stirring a large amount through the whole filling. That way, the casserole stays savory with occasional sweet-tart bites.
Serve it with: A simple green salad for an easy meal after the holiday rush.
How to Choose Casseroles for Your Christmas Menu
A balanced menu is easier to manage than a table full of dishes that all need different oven temperatures.
For Christmas morning, choose one substantial breakfast casserole and add fruit, yogurt, or toast. For dinner, pick one potato or rice dish, one vegetable side, and your main course.
If you’re serving a casserole as the main, keep the extras simple. Lasagna doesn’t need three more heavy sides, and a hearty breakfast bake can do most of the work on its own.
Tips for Making Holiday Casseroles Easier
- Check the baking dish size. A deeper or smaller dish can change how quickly the center cooks.
- Write down oven temperatures and baking times. Choose dishes that fit your available oven space.
- Keep crunchy toppings separate when preparing ahead. Add them at the point your recipe directs.
- Remove excess moisture from vegetables. Well-drained spinach, mushrooms, broccoli, and potatoes help protect the texture of the finished dish.
- Label anything you prepare ahead. Include the casserole name and the baking instructions so someone else can help.
- Follow each recipe’s make-ahead directions. An overnight breakfast bake and a potato gratin don’t necessarily handle advance preparation the same way.
A Cozy Christmas Meal Without So Much Last-Minute Cooking

Choose a few favorites, plan your oven space, and give yourself permission to keep the rest simple.
Save these holiday casserole ideas for Christmas breakfast, Christmas Eve dinner, and all those delicious leftovers.
