Looking to add something comforting to your Thanksgiving menu? These Thanksgiving casserole recipes have you covered. They’re hearty enough for a holiday feast, familiar enough to please picky eaters, and easy enough to fit into a busy cooking day. Many can also be prepped ahead, which gives you more time to focus on the turkey, desserts, and everything else on your Thanksgiving to-do list. From creamy classics to cheesy new favorites, there’s plenty here to tempt everyone at the table.
1. The Cheesy Green Casserole Everyone Will Dig into
Frozen spinach gets a creamy makeover in this comforting casserole. Sour cream, cream cheese, Parmesan, and mozzarella give it a rich, cheesy texture, while a little nutmeg adds gentle warmth. A layer of breadcrumbs bakes up golden and crisp on top, adding some much-needed crunch to the soft, creamy filling. It’s also an easy way to sneak more greens onto the Thanksgiving table. Be sure to squeeze as much liquid as possible from the thawed spinach before mixing it in to keep the casserole from turning watery.
2. A Golden Corn Casserole for the Holiday Table
If your Thanksgiving plate has room for one more cozy side, make it this corn casserole. The mixture bakes up soft and spoonable with a lightly golden top, making it an easy match for turkey, gravy, and all those other hearty dishes. A glass baking dish works nicely here, since you can see the edges browning as the casserole cooks. Give it a few minutes to settle after taking it out of the oven before scooping. That short rest helps the casserole hold together better and keeps those first servings from turning into a very loose pile of corn.
3. The Leek and Potato Bake Worth Making Room for
The secret to this potato gratin isn’t just the cheddar, cream, and sautéed leeks. It’s how you arrange the potatoes. Slice them thinly and stack them upright in the baking dish so more edges are exposed, giving you plenty of golden, crispy bits once the foil comes off. Use a mandoline slicer to get consistently thin slices, which helps everything cook more evenly. The sauce gets extra flavor from white wine, garlic, smoked paprika, thyme, and rosemary, while the mature cheddar adds plenty of savory richness. It’s also a great make-ahead candidate because leftovers reheat well covered with foil.

4. A Creamy Green Bean Casserole with the Best Topping
If you’re making green bean casserole for Thanksgiving, don’t skip the crispy onion topping. It adds the crunchy contrast this creamy mix of green beans, mushrooms, Parmesan, and cream of mushroom soup needs. For the best texture, cook the green beans just until crisp-tender before assembling the casserole. They’ll continue cooking in the oven, so overcooking them at this stage could leave you with mushy beans. You can also assemble the casserole up to 48 hours ahead, cover the baking dish tightly, and refrigerate it until you’re ready to bake.
5. A Golden, Cheesy Gratin with a Garlic Kick
Roasted garlic takes this potato au gratin beyond your everyday cheesy potato bake. An entire head of garlic is roasted until soft and golden, then mashed into a creamy mixture with thyme, nutmeg, Parmesan, and milk before it’s poured over thinly sliced potatoes. A mandoline makes it easier to get evenly thin slices, helping the potatoes cook at the same rate. Cover the dish with foil for the first part of baking to help the potatoes soften, then uncover and finish with Gruyère or mozzarella and Parmesan for a bubbly, golden top.
6. A Cheesy Savory Bread Pudding Worth Making Ahead
If you’re torn between stuffing and something extra cheesy, this savory bread pudding gives you a little of both. Cubes of baguette or sourdough soak up a custard made with eggs and half-and-half, then get plenty of flavor from Gruyère, Swiss cheese, sautéed shallots, sage, and chives. Day-old or slightly stale bread works best here because it absorbs the custard without turning soggy. You can also assemble the whole thing the night before and refrigerate it in a ceramic baking dish, then bake it when you’re ready.
7. Pot Pie Comfort Without All the Pie-Making Fuss
This casserole gives you all the cozy appeal of chicken pot pie without asking you to fuss over a bottom crust. The filling combines rotisserie chicken, carrots, peas, two kinds of baby potatoes, and a creamy white wine sauce seasoned with thyme and garlic. Then, instead of making pastry from scratch, you simply lay thawed puff pastry over the top and bake until flaky and golden. The chicken and vegetable filling can be made up to two days ahead and refrigerated, so all you need to do on Thanksgiving is add the pastry and bake.
8. A Hearty Sausage Casserole with Plenty of Smoky Flavor
Here’s a hearty casserole worth adding to your menu. It combines browned sausages, spicy chorizo, cannellini beans, red peppers, tomatoes, and plenty of smoky paprika in a rich, flavorful sauce. Browning the sausages first is worth the extra step, as the caramelized bits and rendered chorizo fat add extra depth to the sauce. Everything then simmers in the same casserole dish or heavy-bottomed pan, so there are fewer dishes to wash. It’s also a great make-ahead option, as the flavors deepen as it rests.
9. Gnocchi Makes This Greens Gratin Extra Hearty
Swiss chard and gnocchi might not be the first pairing that comes to mind for Thanksgiving, but this gratin makes a pretty convincing case for it. The store-bought gnocchi are browned in butter and olive oil before joining wilted Swiss chard, caramelized red onion, and a creamy sauce flavored with Gruyère, Parmesan, Dijon, garlic, cayenne, and nutmeg. Don’t skip squeezing the cooked chard well because excess water could thin out the sauce. The casserole is baked until bubbling, then briefly broiled so the top develops those browned spots.

10. A Holiday-Ready Broccoli Casserole with a Crispy Top
Broccoli might not be the most exciting vegetable on its own, but add cheddar and a crunchy cracker topping, and suddenly everyone is interested. This casserole combines tender broccoli with a creamy soup base and plenty of shredded cheese. Use a box grater to shred the cheddar fresh for an even melt, then cover everything with crushed crackers for a golden finish. I’d leave some of the crackers in larger pieces rather than crushing them into fine crumbs, since those bigger bits give the topping more texture.
11. A Creamy Fall Casserole with Plenty of Savory Flavor
This hearty casserole brings together roasted butternut squash, cauliflower, and shallots with Italian sausage in a creamy white wine sauce. Fresh sage, garlic, Parmesan, and red pepper flakes give the sauce plenty of savory flavor, while mozzarella creates a bubbly, golden topping. Roasting the vegetables first helps them develop caramelized edges before everything is combined in a baking dish. A few minutes under the broiler give the cheese an especially browned finish.
12. A Southern-Inspired Sweet Potato Showstopper
If you like your sweet potato casserole on the sweeter side, this Southern-inspired version brings plenty of holiday flavor to the table. Roasted sweet potatoes are combined with maple syrup, brown sugar, warm spices, raisins, butter, and marshmallows, then finished with maple-coated pecans. The roasted potatoes add more depth than simply boiling them, while the combination of soft marshmallows and crunchy pecans gives the casserole plenty of texture. Line the baking sheet with parchment paper when roasting the sweet potatoes to make cleanup easier.
13. A Colorful Layered Gratin for the Thanksgiving Table
This gratin makes a colorful Thanksgiving side out of thinly sliced potatoes, sweet potato, zucchini, yellow squash, tomatoes, and red onion. The vegetables are arranged in overlapping layers, with seasoned panko and Parmigiano-Reggiano tucked between them for a crisp, cheesy finish. A mandoline slicer is particularly useful here because the recipe calls for very thin, even slices, especially for the onion. Everything bakes together on a sheet pan, then gets another layer of panko before a quick broil turns the top golden and crunchy.

14. A Sweet-and-Savory Spin on Thanksgiving Stuffing
Apple, bacon, golden raisins, celery, onion, and fresh sage give this stuffing plenty of contrast, with crisp bacon and tart Granny Smith apple cutting through the buttery bread. The recipe uses hearty one-inch bread cubes, which hold onto the seasoned chicken stock without turning completely mushy. A large mixing bowl makes it easier to toss all the ingredients together evenly before transferring everything to a baking dish. Covering the dish with foil keeps the stuffing moist before a final uncovered bake creates a crisp top.
15. A Golden, Bubbly Mac and Cheese for Thanksgiving
This Southern-style baked mac and cheese is all about a rich, creamy center and a deeply golden cheese topping. Short-cut pasta is combined with whole milk, eggs, sour cream, cheddar, and Colby Jack before baking, creating a casserole that sets up beautifully while staying wonderfully cheesy. Cajun seasoning adds a little extra savory kick without taking over the dish. Use a box grater to shred the cheddar and Colby Jack, which melt into the pasta for a smooth, gooey texture. Fresh basil or parsley adds a bright finish before serving.
16. This Cheesy Ravioli Casserole Feels Extra Comforting
This is the kind of casserole that makes a holiday table feel extra cozy. Cheese-filled ravioli is layered with creamy garlic sauce, sautéed mushrooms, spinach, and Parmesan, then baked until the top is bubbling and lightly browned. It’s a deliciously comforting addition to Thanksgiving casserole recipes, especially if you want to serve something beyond the usual side dishes. Browning the mushrooms first gives them a richer flavor and keeps excess moisture out of the bake. Finish with parsley and red pepper flakes for a little color and brightness.
17. A Hearty Wild Rice Casserole with Fall Flavor
With tender chicken, roasted butternut squash, wild rice, dried cranberries, toasted pecans, and Parmesan, this casserole brings several Thanksgiving favorites together in one dish. The cranberries add little bursts of sweetness, while pecans give the soft rice and squash plenty of crunch. An instant-read thermometer is useful for checking the chicken without cutting into every piece, and parchment paper makes cleanup easier. Fresh thyme ties everything together and gives this hearty casserole a distinctly fall-inspired finish.
18. A Hearty Mushroom Casserole Made for Sharing
Love stuffed mushrooms but don’t want to fuss with filling individual caps? This casserole takes all those flavors and turns them into a scoopable side. Quartered mushrooms are cooked with garlic before being coated in cream cheese, mozzarella, and Parmesan, then finished with a buttery breadcrumb topping. Cooking off most of the mushrooms’ liquid first helps keep the casserole from becoming watery. The buttery breadcrumb topping adds the crisp texture you want against all that creamy mushroom goodness.
19. A Cozy Cauliflower Gratin with Plenty of Cheesy Flavor
There’s plenty of flavor packed into this creamy cauliflower bake. Smoked Gruyère gives the sauce a deeper flavor than a standard cheese gratin, while Dijon-coated sourdough pieces create a crunchy contrast to the tender cauliflower underneath. Since the cauliflower is softened before baking, the casserole needs less time in the oven. A box grater works well for freshly shredding the Gruyère and Parmesan, while a pastry brush makes it easy to coat the torn sourdough pieces evenly.
20. A Cheesy Cornbread Casserole with Plenty of Fresh Zucchini
This casserole is a fun way to combine tender zucchini, sweet corn, cheddar cheese, and a little jalapeño in one cozy bake. Corn muffin mix gives the dish its soft, lightly sweet cornbread texture, while shredded zucchini keeps the center moist. Garlic powder and cumin add savory flavor without overpowering the vegetables, and a layer of cheddar on top turns golden as it bakes. Be sure to drain the zucchini well before mixing everything. If you’re looking for Thanksgiving casserole recipes beyond the usual potato and green bean options, this makes a colorful and comforting side.
21. This Pumpkin Cauliflower Gratin is Creamy and Comforting
Pumpkin and cauliflower make an unexpectedly good Thanksgiving pairing in this rich, savory gratin. The cauliflower is coated in a creamy pumpkin-Gruyère sauce seasoned with paprika, black pepper, and nutmeg, then baked until bubbling and golden. Using an oven-safe cast-iron skillet keeps the whole dish together from stovetop to oven and gives the edges plenty of opportunity to brown. Freshly shredded Gruyère also melts more smoothly into the sauce, while fried sage adds a crisp, aromatic finish. It’s a cozy alternative to sweeter pumpkin sides without losing that unmistakable fall feel.
Final Thoughts
Comforting and nostalgic, these Thanksgiving casserole recipes have all the makings of holiday favorites. They range from creamy vegetable bakes and cheesy potatoes to hearty casseroles that turn simple ingredients into something special.
