I can’t believe it’s almost Thanksgiving. I say that every year, but it really feels like this year is moving incredibly faster than usual.

We can’t slow down time, but we can prepare for the rest of the year early and maybe, just maybe, that will feel like time is slowing down. Which is why now is the best time to plan your Thanksgiving menu.

I know which of my Thanksgiving side dish casseroles I’m making. Corn casserole, if you’re wondering. Classic corn casserole is one of the best Thanksgiving side dish recipes. Who am I kidding? It’s the best. And I know everyone else likes it because it’s one of the best Thanksgiving side dishes and there aren’t ever any leftovers. But no one else will make it. So if I want it at Thanksgiving, I have to be the one to make it.

If you’re looking for a delicious side dish to add to your Thanksgiving meal this year, we have a bunch of casseroles for you below. Casseroles are such an easy side dish because you dump everything in the pan and put it in the oven. That frees up your hands to do everything else you need to do for Thanksgiving.

Vegetarian Brussels Sprouts Casserole

Brussels sprouts are such a staple at the Thanksgiving table. But so many people serve really boring, bland, boiled Brussels. End that right now with this Vegetarian Brussels Sprouts Casserole.

This Brussels sprouts recipe is packed with flavor — and Parmesan cheese. And the delicious flavor of the Brussels sprouts come through. Most Brussels sprouts recipes hide their flavor with bacon, but this doesn’t need to.

This isn’t the easiest casserole recipe because you do have to cook the Brussels sprouts two ways before putting them in the casserole pan, but I promise this side dish is worth it.

Corn casserole.

Corn Casserole

Corn Casserole is my favorite Thanksgiving side dish recipe.

It’s so easy to make from really simple ingredients: canned corn, butter, sour cream, and corn muffin mix. You put all the ingredients into a casserole pan, stir, and bake. There’s nothing to cook ahead of time, so it’s super simple. Which you need on Thanksgiving because everything else you make is really hands on. So this dump and go casserole will be one of your new favorite east Thanksgiving side dishes.

And, leftover corn casserole is even better than the fresh version. Heat it up in the microwave with a dollop on butter on top and it’s incredible. Trust me.

Stuffed Sweet Potato Casserole.

Baked Sweet Potato Casserole

I (patiently) wait for sweet potatoes to hit our local grocery stores so I can buy them and make this Baked Sweet Potato Casserole. What I really love about it is you don’t need a casserole pan. You can just bake the “casserole” right in the sweet potato itself.

You bake the sweet potatoes, then cut them open and add butter, brown sugar, and mini marshmallows. You bake again and that’s that. You get all the flavors of sweet potato casserole, just not in casserole form. It’s a really fun twist on a classic.

If you bought too many potatoes for this, check out our long list of sweet potato recipes for ways to use them up.

Mushroom and Rice Casserole.

Mushroom And Rice Casserole

I usually make this Mushroom And Rice Casserole as dinner for me and Pete, but if you’re having a crowd over for Thanksgiving dinner, you can serve it as a side dish.

This hearty casserole is really easy to make. The rice cooks in the casserole pan (thanks to a little help from canned cream of mushroom soup and water), so you don’t have to cook it ahead of time or separately, which is less steps for you.

A lot of vegetarian recipes call for mushrooms to substitute for meat (like our Vegetarian Philly Cheesesteak recipe) because mushrooms are pretty substantial and filling. So, if you needed something to serve as a main dish casserole, this would work as that.

Two pieces of cornbread with the words "Cheesy Zucchini Cornbread Casserole" digitally written on top.

Cheesy Zucchini Cornbread Casserole

You can’t go wrong with this Cheesy Zucchini Cornbread Casserole. It’s a delicious twist on traditional cornbread that’s more moist than the traditional side. This cornbread casserole is packed with a full pound of zucchini and a ton of cheddar cheese — inside and on top. The cheese on top turns a beautiful golden brown that’s sure to entice everyone at your holiday table. 

Cornbread casserole is most interesting than regular cornbread, which is served at nearly every Thanksgiving dinner. Tiny, dry corn muffins are aways on the table, but no one really wants to waste the room in their stomach on them. If you jazz up the cornbread with zucchini, you’ll have way less left at the end of the meal.

Mushroom And Kale Pasta Casserole

If you can’t decide between pasta salad, veggies, or a casserole, you can combine all of them with this Mushroom And Kale Pasta Casserole recipe. Plus, part of the fun of Thanksgiving is mixing all your food together and trying to eat as much of it as you can. This casserole basically does that for you.

This casserole is really good reheated the next day with a little bit of olive oil on top. So if you have some leftover, it’s a great lunch for Black Friday. And, that way, you’re not the one stuck eating leftover turkey sandwiches for the rest of the weekend.

Mini Hash Brown Casserole.

Mini Hash Brown Casserole

Don’t mind that this says it’s a breakfast casserole. We actually eat this Mini Hash Brown Casserole as dinner more often than breakfast. But hash browns just feel like breakfast most days. But not on turkey day. On Thanksgiving, hash browns feel like a great side dish and an alternative to mashed potatoes.

This hash brown casserole is cute because it’s served in individual ramekins. So, if you’re having a small Thanksgiving, these will be perfect. If you’re having a lot of guests, you can just make this in a casserole pan instead.

What size casserole dish do I need for side dishes?

Quick fun facts: A casserole dish and a baking dish are the same thing. They’re just different ways of referring to the same pan.

A casserole pan is an oven-safe pan, which is one to two inches deep, made of a variety of materials. Mine are ceramic, but they also come in glass, metal, and more. Traditionally, they’re circular (I have an oval and a circle). They can also be square or rectangular. And they come in a variety of sizes.

For these side dish casseroles, I use a 1.5-quart round casserole pan. That’s the perfect size for a side dish. For our main dish Thanksgiving casseroles, I use a 2.5-quart oval casserole pan.

You don’t want to use that large of a casserole dish for side dishes. You’ll pull it out and people will think it’s a main dish since the pan is so large, and they’ll fill up on it. Then, no one will have any room for your roast turkey (or whatever you’re serving as your main dish).

If you use a smaller casserole pan, they’ll understand it’s just a side and scoop out an appropriate portion.

These all look great! My all-time favorite is sweet potato casserole. And for something different this year, I am actually trying a brussels sprouts salad. I may add one of these casseroles as well.
