I don't know about you, but oven space on Thanksgiving is practically a luxury item. That's why I lean so hard on casseroles, those bubbly, golden, warm and cozy dishes that feed a hungry crowd without a fuss. They're the real heroes of the holiday table. I've rounded up 24 of my absolute favorite Thanksgiving casseroles right here, from cheesy potato beauties to fresh veggie bakes that will have everyone asking for seconds.
1. Carrot Casserole
I have to be honest, I usually only bother with carrots when they're slicked in a sweet buttery glaze. Then I stumbled on this casserole and thought, how on earth did I not think of this sooner? You start with an easy roux seasoned with flour, salt, mustard, pepper, and milk, then stir in plenty of cheese until it's all melty and wonderful.
2. Southern Squash Casserole
You can absolutely use zucchini for this one, but if you spot some sunny summer squash at the store, grab it. That gorgeous yellow color makes any table feel instantly brighter and so welcoming. If you want to get extra pretty with it, use a mix of both and arrange them in alternating green and yellow rows before you bake.
3. Creamed Spinach Casserole
If you plopped a sad pile of wilted spinach on my plate, I'd grin and eat it because manners matter. But I'd be secretly wishing the whole time it was buried under cheese! I do love sautéed spinach with lots of onions and garlic, but let's be real, creamed spinach is in another league. This version goes all out with artichoke hearts and cream cheese, so it eats more like a thick, dreamy spinach and artichoke dip.
4. Cheesy Baked Mashed Potatoes
Cheese is my ultimate weakness, the reason I could never go fully vegan. I'm all for cutting back on meat and dairy most days, but giving it up entirely? Nope, not happening. The holidays are made for indulging, so why on earth would I serve plain old mash when I could serve this cheesy, bubbling, ridiculously good Thanksgiving casserole instead?
5. Butternut Squash Mac and Cheese
I am all about sneaking extra veggies into pasta sauces whenever I can. This little trick with butternut squash is so clever, and I'd bet good money the kids won't even notice a thing. It melds right into the mac and cheese, making everything a touch sweeter and even more velvety.
6. Roasted Vegetable Winter Crumble
A savory vegetable pie is such a great move for a vegetarian or vegan friendly option, it's hearty and filling without any fuss. You can serve it as a side alongside the turkey or let it be the star for your plant based guests. I have zero patience for fussy pastry, so a crumble top is my absolute lifesaver. It's a cinch to throw together and somehow always looks effortlessly pretty.
7. Broccoli Rice Casserole from Scratch
I'm always looking for ways to get those little green florets onto the table without a single pouty face. Honestly, besides broccoli and cheddar soup, this is about as good as it gets. I love broccoli just as it is, but I know plenty of kiddos need a little convincing. Fold it into tender rice with plenty of melty cheese and I'm willing to bet they'll be scooping up more before you know it.
8. The Pioneer Woman’s Twice Baked Potato Casserole
This is the kind of dish that saves your sanity on the big day. You can whip it up two full days before the turkey even hits the oven. It starts with a simple batch of creamy mashed potatoes, then things get wildly good with butter, sour cream, milk, crispy bacon, and a generous handful of grated cheese all folded right in.
9. Cheesy Root Vegetable Gratin
Can we just talk about how stunning this dish looks? Those vibrant colors and crunchy strips practically holler at you to grab a fork. You'll layer in sweet potato, parsnips, and beets, but don't be shy about swapping in radishes or even blue potatoes if you spot some. I recently found some golden beets that looked absolutely show stopping nestled in all that cheese.
10. Zucchini Tomato Casserole
This one looks a lot like a veggie lasagna with those gorgeous zucchini layers and juicy tomatoes soaking into everything. There's also a yummy layer hiding in there made from cream cheese, milk, basil, and a touch of nutmeg, all finished with a generous sprinkle of cheese on top. It's fresh, creamy, and so satisfying.
11. Turnips Au Gratin
Turnips are funny little things, sort of like potatoes once they're cooked but with their own quiet personality. Sometimes I get a gentle peppery note from them, other times a hint of sweetness. Here they take a lovely bath in a creamy, garlicky sauce under a blanket of cheese, so any sharpness mellows right out into something cozy and irresistible.
12. Brussels Sprouts and Grapes au Gratin
Brussels sprouts can be a hard sell, I get it. But smother them in a creamy sauce with plenty of cheese and suddenly nobody's complaining. Now the grapes might sound like a wildcard, I promise it's not as odd as it sounds. They bring this little pop of color and a whisper of sweetness that plays so nicely with turkey and cranberry sauce.
13. Apple Fritter Casserole
If a festive dessert that's a total breeze sounds like your kind of holiday, say hello to this apple fritter casserole. I've mentioned I don't have the patience for finicky pastry, and this one totally gets me. You'll make a spiced apple filling with plenty of sugar, then crown it all with canned crescent rolls for a shortcut that feels surprisingly homemade.
14. Incredibly Easy French Onion Soup Casserole
French onion soup is pure richness, that deep intense broth swirled with all those jammy onions. The real secret to making it sing is a dark, meaty beef broth that brings maximum savoriness. It's piled high with cheese on top, so this is one recipe where I wouldn't dream of swapping in veggie broth for a vegan version, it would just fall flat and taste too mellow.
15. White Chocolate Cranberry Dessert Casserole
Tender vanilla cake, dreamy white chocolate mousse, and tart cranberry compote all in one dish, now that's a Thanksgiving dessert worth celebrating. Go ahead and use a boxed cake mix to save time, I swear nobody will ever guess. This recipe happens to be vegan, made with soy milk and coconut cream, so if you want to keep it that way just follow the written ingredients closely.
16. Potato Leek Casserole
Leeks have this lovely onion and garlic flavor but with a soft, light sweetness underneath. Their pale green color also just looks so pretty in a dish. This casserole is a playful spin on classic potato au gratin, with the same kind of creamy cheese sauce but studded with all those tender leeks. Be sure to slice and rinse them well, dirt loves to hide between those layers.
17. Pineapple-Bourbon Sweet Potato Casserole
Sweet potato, marshmallow, and pineapple together might raise an eyebrow, but trust me, they're meant to be. I've been known to say sweet potato casserole can get a little too sweet, and I have a serious sweet tooth, so that's saying something. The tart pineapple is the hero here, adding a bright fruitiness that cuts right through the sugar like a charm.
18. Eggplant Casserole
It might not be vegan, but this is a fantastic vegetarian option for your Thanksgiving spread. You'll start with the usual suspects, onions and garlic, then toss in peppers and mushrooms and let everything cook down until most of the liquid is gone. Tomatoes and herbs come next to finish that rich sauce, and right before it's done you'll gently fold in some lightly sautéed eggplant.
19. Potato Stuffing Casserole
Out of every Thanksgiving casserole on this list, this might be the most brilliant. It saves you from washing extra dishes and frees up precious oven space, which is basically a holiday miracle. How does it work? You take your favorite go-to stuffing recipe and simply stir it right into a batch of creamy mashed potatoes. Two fan favorites in one easy dish, done.
20. One-Pan Broccoli Cheese Wild Rice Casserole
Wild rice brings a bit more to the party than plain white rice, it's packed with protein and antioxidants, plus I love the hearty texture and the way it looks so colorful on the plate. This one is a close relative to the broccoli rice casserole you know and love, but it skips the heavy cheese sauce in the middle so the wild rice can really come through.
21. Rutabaga Gratin
Over in the UK they call this root veggie a swede, which is fun. It belongs to the turnip family but tends to get passed over when dinner time rolls around. Imagine a flavor that sits somewhere between cabbage, turnip, and potato, with that same golden yellow hue once cooked. I find rutabaga has a slightly more distinct personality than a turnip, but it's every bit as delicious in a creamy gratin.
22. Loaded Cauliflower Casserole
Think of this as the lighter cousin to a loaded potato bake, but honestly? It doesn't skip out on any of the good stuff. You still get all that glorious cheese and bacon, just nestled into tender cauliflower instead of spuds. Since cauliflower is so mellow on its own, a dreamy mix of cream cheese, sour cream, cheddar, Monterey Jack, garlic powder, and onion powder wakes the whole dish right up.
23. Green Pea Casserole
Remember when I mentioned these casseroles are all about keeping things easy? This one takes that to heart. Besides chopping an onion and a pepper, all you do is open a few cans and give everything a good stir. Frozen peas, pimentos, water chestnuts, and mushroom soup come together in a dish that's bursting with crunch and fresh flavors. Want even more color? Swap in a veggie medley instead of just peas.
24. Mushroom Casserole
When mushrooms are cooked just right, they take on this wonderful meaty quality. They add a chewy in a good way bite to your plate, especially next to all those soft mashed potatoes and tender stuffing. The key is letting them hit a hot pan first to cook off their excess moisture. Skip that step and you'll end up with something rubbery and slimy, and nobody wants that.
