It takes a familiar side and gives it a sophisticated, savory twist that complements everything else on the plate.
It’s a fantastic choice because it strikes a balance between tradition and a modern update. The combination of tender green beans, a rich creamy sauce, savory bacon, and crunchy shallots provides a complex texture and flavor that stands out.

A true holiday staple, this casserole walks the fine line between side dish and dessert. Creamy, mashed sweet potatoes are topped with a crunchy, buttery pecan and brown sugar streusel. It’s the sweet counterpoint to all the savory dishes on the Thanksgiving table.

3. Cheesy Brussels Sprouts Casserole

For those who claim to dislike Brussels sprouts, this dish is a delicious challenge to that opinion. When roasted, shredded, and baked in a creamy cheese sauce, these little cabbages transform into something utterly crave-worthy.
This casserole is a great way to get some greens on the table in a format that even picky eaters might try. The cheese sauce mellows the sometimes-bitter flavor of the sprouts, making them savory and satisfying.

- Next Steps: Experiment with different cheeses. A mix of Gruyère and white cheddar adds a wonderful depth. A pinch of nutmeg in the cream sauce will also elevate the entire dish.
4. Perfect Potatoes au Gratin

If you want a comfort food that doesn’t discriminate, get potatoes. Scalloped potatoes have a more refined cousin, and its name is Potatoes au Gratin. This elegant dish features thinly sliced potatoes layered with a decadent, creamy cheese sauce and baked until golden and bubbly.
It brings a touch of French-inspired elegance to the Thanksgiving table. It feels special, but the preparation is straightforward. It’s a hearty, comforting side that pairs beautifully with turkey and gravy.
Quick Glance:
- Pro-Tip: Use a mandoline for uniformly thin potato slices. This helps them cook evenly. Russet or Yukon Gold potatoes are excellent choices as their starchy texture helps thicken the sauce.
- Next Steps: Prepare the dish up to the point of baking one day ahead. Press a piece of plastic wrap directly onto the surface of the potatoes to prevent discoloration before covering and refrigerating.
5. Cornbread Stuffing with Chorizo

Stuffing is a non-negotiable Thanksgiving side, and this version brings a little something extra. The sweetness of cornbread is balanced by the smoky, spicy kick of chorizo sausage, creating a robust and memorable flavor profile.
If your Thanksgiving menu needs a little excitement, this is the dish to add. It delivers on the comforting texture of traditional stuffing but introduces a bold flavor that will have guests talking.
Quick Glance:
- Pro-Tip: You can bake your cornbread two or three days in advance. Stale cornbread actually absorbs the other flavors better. Cook the chorizo and vegetables ahead of time as well.
- Next Steps: On Thanksgiving morning, combine all the prepared components, add your broth or stock, and bake. If you prefer a moister stuffing, feel free to add a bit more liquid.
6. Twice-Baked Potato Casserole

Imagine all the best parts of a loaded baked potato, but in a convenient, shareable casserole form. Fluffy potato insides are mashed with sour cream, cheese, chives, and bacon, then baked again until hot and melty.

Introducing a dish for anyone who daydreams about second helpings before the first one is gone: Jalapeño Popper Chicken Casserole. This bake takes the creamy, cheesy, a little bit daring party spirit of jalapeño poppers and transforms them into a main event. Shredded chicken is folded into a rich, tangy cream cheese sauce, loaded with chopped jalapeños, bacon crumbles, and a shower of melty cheese.
It’s all crowned with a buttery, crunchy topping, just so everyone at the table is on notice that this is not your average casserole. Leftover turkey even works as a stand-in for chicken here, so it doubles as a post-holiday miracle worker.
Quick Glance:
- Pro-Tip: To tame the spice, remove the seeds and membranes from the jalapeños, or trade in a few for milder peppers. For the boldly brave, leave them in or swap some for hotter varieties.
- Next Steps: Prep the base ahead of time and refrigerate. Just add the crunchy topping before baking. Pair with a crisp salad or some roasted veggies for balance. Use gloves when chopping jalapeños.
8. Cheesy Sausage and Croissant Casserole

This dish is technically a breakfast casserole, but its savory richness makes it a perfect, unexpected addition to the Thanksgiving spread. Flaky croissants are soaked in a savory egg custard with sausage and plenty of cheese.
Serve it for a Thanksgiving brunch, or put it on the dinner table as a unique, bread-based side that can stand in for stuffing. It’s rich, decadent, and feels like a treat.
Quick Glance:
- Pro-Tip: Use day-old, slightly stale croissants. They will hold their shape better and soak up the egg mixture without becoming completely soggy.
- Next Steps: Assemble the entire casserole the night before. This allows the croissants to fully absorb the custard. In the morning, just pop it in the oven for a hands-off, delicious dish.
9. Cauliflower Gratin

Cauliflower Gratin offers a similar creamy, cheesy experience to potatoes au gratin, but with a lighter feel. Tender-cooked cauliflower is enveloped in a rich cheese sauce and baked with a crunchy, golden-brown topping.
This is a wonderful option for those looking for a lower-carb alternative to potato dishes without sacrificing flavor or comfort. It’s elegant, delicious, and a great way to feature a vegetable in a celebratory way.
Quick Glance:
- Pro-Tip: Steam or blanch the cauliflower florets until they are just tender-crisp. Overcooking them beforehand can lead to a mushy final product.
- Next Steps: The cheese sauce is your canvas. Add a pinch of cayenne for warmth, some Dijon mustard for tang, or a blend of cheeses like Gruyère and Parmesan for a nutty, salty flavor.
10. Turkey Tetrazzini

This casserole is the ultimate plan for Thanksgiving leftovers, but it’s so good you might want to make it with pre-cooked turkey breast. It’s a creamy pasta bake with turkey, mushrooms, and peas in a rich Parmesan cream sauce.
If you’re wondering how to reinvent your Thanksgiving turkey, try the turkey tetrazzini. It turns leftovers into a completely new and exciting meal, perfect for the day after the big feast when no one wants to cook.

The hashbrown breakfast casserole combines frozen hash browns, eggs, shredded cheese, and your choice of sausage or bacon into a hearty, oven-baked dish. It is designed for efficiency and flavor, making it a reliable option when you need to feed a group with minimal prep. Thaw the hash browns and press out excess moisture before mixing to avoid sogginess and ensure a crisp finish.
You can assemble the casserole the night before and refrigerate it until ready to bake, which helps streamline your schedule on busy mornings or holidays. Swap the meat for ham, add chopped vegetables like bell peppers or onions, or use a blend of cheeses for more depth. Once baked, it holds well for serving and reheating, making it a practical choice for gatherings or leftovers.
Quick Glance:
- Pro-Tip: Thaw the frozen hash browns and squeeze out as much moisture as possible before mixing them with the other ingredients. This is the secret to avoiding a watery casserole and getting a crispier texture.
