Thanksgiving casseroles have one huge advantage: they can quietly wait in the refrigerator while you deal with everything else.
That matters on Thanksgiving.
The turkey needs attention. Gravy suddenly needs whisking. Someone wants to know where the serving spoons are. And somehow the rolls still aren’t in the oven.
This is exactly why I love casseroles for the holiday table.
You can assemble many of them ahead, cover the dishes, and come back when you’re ready to bake.
For these Thanksgiving casserole recipes, we’re making five very different sides: creamy green bean casserole, cheesy potato casserole, savory corn casserole, cranberry sweet potato casserole, and broccoli cheddar casserole.
They’re cozy without all tasting the same.
And yes, we’re going to talk about oven timing too.
Because five casseroles are only helpful if you can actually get them onto the table.

The Green Bean Casserole With a Creamy Homemade Sauce
Creamy Green Bean Casserole
Green bean casserole is one of those dishes people expect to see somewhere on the Thanksgiving table.
This version skips canned condensed soup and makes a quick mushroom sauce instead.
Bring a large pot of salted water to a boil.
Add the green beans.
Cook for about 4 minutes, until bright green and just beginning to soften.
Drain and immediately rinse under very cold water or transfer them to ice water.
Drain thoroughly.
Preheat the oven to 375°F.
Melt the butter in a large skillet over medium heat.
Add the mushrooms.
Cook for 6 to 8 minutes, until they’ve released their moisture and started to brown.
Add the garlic.
Cook for another 30 seconds.
Sprinkle the flour over the mushrooms.
Stir for about 1 minute.
Slowly pour in the milk and chicken broth while stirring.
Add Worcestershire sauce, salt, and black pepper.
Cook until the sauce thickens enough to lightly coat the back of your spoon.
Add the green beans.
Stir gently.
Transfer everything to a baking dish.
Bake uncovered for about 20 minutes.
Scatter the crispy fried onions over the top.
Bake another 8 to 10 minutes, until bubbling around the edges.
Save the fried onions for the end.
Put them on too early and those crispy little pieces can become soft.
Nobody came to Thanksgiving hoping for damp fried onions.
Pro Tips
Undercook vegetables slightly before baking. They’ll continue cooking inside the casserole.
Grate your own cheese when you can. It usually melts more smoothly into sauces.
Don’t add crunchy toppings too early. Breadcrumbs, nuts, and fried onions are much better when they stay crisp.
Use shallow casseroles when oven space is tight. They’re easier to arrange and often heat more evenly.
Write baking instructions on the foil. When five dishes are waiting in the refrigerator, you’ll be very glad you did.
A Cheesy Potato Casserole Worth Making Room For
Cheesy Potato Casserole
There are already mashed potatoes on many Thanksgiving tables.
Do you still need cheesy potatoes?
This is between you and your family.
I’m just giving you the recipe.
Preheat the oven to 375°F.
Peel the potatoes if desired.
Slice them into thin rounds, approximately 1/8 inch thick.
Try to keep them similar in thickness.
Melt the butter in a saucepan.
Add the onion.
Cook for about 4 to 5 minutes, until softened.
Add the garlic and cook for another 30 seconds.
Sprinkle in the flour.
Stir continuously for 1 minute.
Gradually whisk in the milk and heavy cream.
Season with salt and black pepper.
Cook until slightly thickened.
Remove from the heat.
Stir in 1 1/2 cups cheddar and the Parmesan.
Arrange about one-third of the potatoes in a greased 9×13-inch baking dish.
Spoon some sauce over them.
Repeat the layers.
Finish with the remaining sauce.
Cover tightly with foil.
Bake for 45 minutes.
Remove the foil.
Add the remaining cheddar.
Bake for another 20 to 30 minutes, until the potatoes are completely tender and the top is golden.
Let the casserole rest for about 10 minutes.
Finish with chopped chives.
Test the potatoes before removing the casserole from the oven.
A knife should slide easily through the center.
Golden cheese on top means very little if the potatoes underneath are still crunchy.
The Corn Casserole That Sits Somewhere Between Bread and Side Dish
Savory Corn Casserole
This one is soft in the middle, lightly golden around the edges, and full of sweet corn.
It also happens to be ridiculously easy to mix.
Preheat the oven to 350°F.
Grease a 2-quart baking dish.
In a large bowl, whisk the eggs.
Add sour cream, milk, and melted butter.
Mix until combined.
In another bowl, combine the cornmeal, flour, sugar, baking powder, and salt.
Add the dry ingredients to the wet mixture.
Stir gently.
Fold in the corn, cheddar, and green onions.
Pour into the prepared baking dish.
Bake for approximately 35 to 45 minutes, until golden around the edges and set in the center.
Let it rest for 10 minutes before serving.
The center should stay soft.
You’re not trying to turn it into a dry block of cornbread.
That little bit of sugar isn’t there to make the casserole sweet.
It just works with the natural sweetness of the corn.
Sweet Potato Casserole Gets a Tart Little Upgrade
Cranberry Pecan Sweet Potato Casserole
Thanksgiving already has plenty of sweet flavors.
So instead of burying the sweet potatoes under a thick layer of marshmallows, we’re adding tart dried cranberries and a crunchy pecan topping.
Peel and cut the sweet potatoes into chunks.
Place them in a large stockpot.
Cover with water.
Bring to a boil and cook for about 15 minutes, or until completely tender.
Drain well.
Mash until smooth.
Add melted butter, maple syrup, milk, eggs, vanilla, cinnamon, nutmeg, and salt.
Mix until combined.
Fold in the dried cranberries.
Spread the mixture into a greased 2-quart baking dish.
Now make the topping.
Combine the pecans, brown sugar, flour, and softened butter.
Mix until crumbly.
Scatter evenly over the sweet potatoes.
Bake at 375°F for 25 to 30 minutes, until heated through and lightly browned.
The cranberries break up all that sweetness nicely.
And the pecan topping gives you the crunchy bit everyone starts stealing from the corners.
You know who you are.
A Broccoli Casserole That Still Tastes Like Broccoli
Broccoli Cheddar Casserole
The goal here isn’t to hide broccoli underneath three inches of cheese.
We’re keeping the broccoli recognizable.
It just happens to be sitting in creamy cheddar sauce underneath buttery breadcrumbs.
Bring a large pot of salted water to a boil.
Add the broccoli.
Cook for about 2 to 3 minutes.
Drain immediately.
You want it bright green and still fairly firm.
Preheat the oven to 375°F.
Melt 3 tablespoons butter in a saucepan.
Whisk in the flour.
Cook for about 1 minute.
Slowly whisk in the milk.
Continue cooking until slightly thickened.
Reduce the heat.
Add the cheddar gradually.
Stir until melted.
Add garlic powder, salt, and black pepper.
Place the broccoli in a greased baking dish.
Pour the cheese sauce over the top.
Mix the breadcrumbs with 2 tablespoons melted butter and Parmesan.
Scatter over the casserole.
Bake for approximately 20 to 25 minutes, until bubbling and golden.
That’s it.
Creamy underneath.
Crispy on top.
Broccoli still has some texture.
Everyone wins.
Which Thanksgiving Casseroles Should You Actually Make?
Please don’t look at five casserole recipes and decide all five must be on your table.
Unless you’re feeding a very large crowd.
Then carry on.
For most Thanksgiving dinners, choose casseroles that don’t duplicate everything else you’re serving.
| Casserole | Main Flavor | Texture | Oven Temp |
|---|---|---|---|
| Green bean | Savory, creamy | Tender and crispy | 375°F |
| Cheesy potato | Rich, cheesy | Creamy | 375°F |
| Corn | Savory-sweet | Soft | 350°F |
| Sweet potato | Maple, cranberry | Creamy and crunchy | 375°F |
| Broccoli cheddar | Cheesy, savory | Creamy and crisp | 375°F |
If mashed potatoes are already on the menu, maybe skip the cheesy potato casserole.
If you’re serving several rich dishes, green bean or broccoli casserole adds more vegetables.
And if sweet potatoes are non-negotiable in your family, that decision has already been made for you.
The Thanksgiving Casserole Trick That Saves the Most Time
Assemble first. Bake later.
That’s where casseroles earn their place on the Thanksgiving menu.
Two Days Before
You can:
- Trim the green beans.
- Cut the broccoli.
- Grate the cheeses.
- Chop the pecans.
- Measure dry ingredients.
- Dice the onions.
One Day Before
Prepare the green bean casserole without the fried onion topping.
Assemble the cheesy potato casserole.
Prepare the sweet potato filling and topping separately.
Blanch the broccoli and prepare its cheese sauce.
You can also measure the corn casserole ingredients.
Cover everything tightly and refrigerate.
Thanksgiving Day
Bring chilled baking dishes toward room temperature only as appropriate for the type of dish you’re using and the manufacturer’s guidance.
Add toppings shortly before baking.
Bake the casseroles.
Keep anything crispy for the final few minutes.
Now Thanksgiving Day involves considerably more putting-things-in-the-oven and considerably less chopping-things-frantically.
That’s progress.
One Oven, Several Casseroles
Here’s some good news.
Four of these recipes bake at 375°F.
That was intentional.
The corn casserole calls for 350°F, but it can generally be baked before the others and reheated later.
If you’re baking multiple casseroles simultaneously, leave enough space around the dishes for hot air to circulate.
They may also need slightly more time.
Don’t rely entirely on the clock.
Check the actual food.
Casseroles should be hot through the center and bubbling where appropriate.
If a topping is browning too quickly, cover it loosely with foil.
And remember that your turkey may have its own oven plans.
Write out your oven schedule the night before.
It sounds slightly excessive.
At 3:30 p.m. on Thanksgiving, it feels brilliant.
Substitutions and Variations
These recipes don’t need to be rigid.
Fresh green beans: Frozen green beans can work. Thaw and drain them thoroughly first.
Cremini mushrooms: White button mushrooms are fine.
Chicken broth: Vegetable broth works in the green bean casserole.
Yukon Gold potatoes: Russets can work, though the finished texture will be slightly different.
Sharp cheddar: Use medium cheddar, Gruyère, Monterey Jack, or a combination.
Whole milk: Half-and-half can create a richer sauce.
Corn kernels: Fresh, frozen, or well-drained canned corn can work.
Dried cranberries: Dried cherries are a good alternative.
Pecans: Use walnuts.
Broccoli: Cauliflower works beautifully with the cheddar sauce too.
For vegetarian casseroles, use vegetable broth in the green bean casserole.
For a nut-free sweet potato casserole, skip the pecans and make a simple brown sugar oat topping instead.
A Few Ways to Keep Thanksgiving Casseroles From Turning Mushy
Casseroles get a bad reputation when everything inside has the same soft texture.
We can avoid that.
Don’t overcook the vegetables before they enter the oven.
Drain boiled vegetables thoroughly.
Cook mushrooms until their excess moisture evaporates.
Keep crispy toppings separate until close to baking.
Don’t drown everything in sauce.
And let casseroles rest briefly before serving.
That last few minutes gives sauces time to settle.
Creamy is good. Watery is not.
There’s a difference.
What to Serve With Thanksgiving Casseroles
These casseroles are side dishes, so build the rest of the meal around them.
They pair naturally with:
- Roast turkey
- Roast chicken
- Glazed ham
- Cranberry sauce
- Homemade gravy
- Dinner rolls
- Fresh salad
- Roasted carrots
- Mashed potatoes
- Stuffing
If you’re serving the potato and sweet potato casseroles, you probably don’t need mashed potatoes too.
Unless your family would consider that a personal attack.
I don’t know your Thanksgiving politics.
How Much Casserole Do You Need?
When several sides are available, people usually take smaller servings of each.
A 9×13-inch casserole can often provide around 10 to 12 side-dish portions, depending on the recipe and serving size.
Smaller 2-quart casseroles generally suit smaller gatherings or tables with lots of other sides.
Think about your menu as a whole.
Six side dishes means nobody needs a giant portion of each one.
Two side dishes means you’ll want more generous amounts.
And make extra of the dish your family actually eats.
Every Thanksgiving table seems to have one casserole that vanishes and another that spends the evening looking increasingly lonely.
Plan accordingly.
Leftovers and Storage
Casserole leftovers are wonderfully easy.
Cool and refrigerate perishable leftovers within 2 hours.
Green bean casserole: Refrigerate for 3 to 4 days.
Cheesy potato casserole: Refrigerate for 3 to 4 days.
Corn casserole: Refrigerate for 3 to 4 days.
Sweet potato casserole: Refrigerate for 3 to 4 days.
Broccoli cheddar casserole: Refrigerate for 3 to 4 days.
Cover tightly or transfer to airtight containers.
Reheat leftovers to 165°F.
For casseroles with crispy toppings, reheating in the oven usually gives you a better texture than the microwave.
A little fresh cheese, breadcrumbs, or fried onions added during reheating can also bring a tired-looking leftover casserole back to life.
