Christmas meals often need more than one baking dish. There is breakfast to think about, a main course to plan, and sides that need their own place on the table. These Christmas casserole ideas cover sweet morning bakes, creamy vegetables, cheesy potatoes, and filling pasta dishes.
You can choose a few sides for roast turkey or ham, or make one hearty casserole the center of a smaller gathering. Some recipes allow overnight prep, while others come together before baking. Check the cooking times and oven temperatures as you plan, then pick dishes that fit your guests and the space in your kitchen.
1. Cheesy Boursin Scalloped Potatoes
Thin Yukon Gold potato slices bake in a creamy garlic and herb Boursin sauce. Mozzarella adds a stretchy topping with golden spots, while fresh chives finish the dish. Keep the slices even so the center softens along with the edges. This rich side pairs well with a simple Christmas roast.
Serve these cheesy Boursin scalloped potatoes with your holiday dinner.
2. Eggnog French Toast Casserole
Toasted, buttered challah pieces soak in an eggnog custard before baking into a tender breakfast with lightly crisp tips.

3. Classic Green Bean Casserole

10. Brown Sugar Glazed Scalloped Sweet Potatoes
Thin sweet potato rounds sit in overlapping circles beneath a glaze of brown sugar, butter, and maple syrup. Cinnamon, nutmeg, and vanilla add warm flavor.

15. Spinach Tomato Feta Breakfast Casserole
Spinach, cherry tomatoes, and feta give this egg bake color and a gently tangy flavor. There is no bread base; eggs and milk hold the vegetables together beneath a thin mozzarella topping.

21. Ham Potato and Green Bean Casserole

25. Sweet Potato Casserole with Marshmallows
