Best Make-Ahead Thanksgiving Side Dishes
Here are some of the best Thanksgiving side dishes to prepare before the big day.
1. Make-Ahead Mashed Potatoes

Creamy mashed potatoes are one of the easiest Thanksgiving sides to prepare ahead.
Make the mashed potatoes up to 2 days in advance and refrigerate them in an airtight container.
On Thanksgiving Day, gently reheat them in a saucepan or slow cooker. Stir in a little warm milk, cream, or butter if they need to be loosened.
2. Make-Ahead Stuffing
Classic stuffing is another Thanksgiving favorite that works beautifully as a make-ahead side.
Prepare the bread mixture, vegetables, herbs, and broth ahead of time. Refrigerate until you’re ready to bake.
For the best texture, bake the stuffing close to serving time so the top becomes golden and slightly crisp.
3. Make-Ahead Green Bean Casserole
Green bean casserole can be assembled ahead of time and refrigerated.
Prepare the green beans and creamy sauce, then assemble the casserole in its baking dish. Cover and refrigerate.
Add the crispy fried onions shortly before baking so they stay crunchy.
4. Make-Ahead Sweet Potato Casserole
Sweet potato casserole is perfect for holiday meal prep.
Prepare the sweet potato mixture and place it in a baking dish up to a couple of days ahead.
Add the topping before baking and heat until the casserole is hot and golden.
5. Make-Ahead Cranberry Sauce

Cranberry sauce is one of the easiest Thanksgiving recipes to make ahead.
In fact, making it a day or two early allows the flavors to develop while the sauce chills in the refrigerator.
Serve it cold, cool, or slightly warmed depending on your preference.
6. Make-Ahead Mac and Cheese
Creamy baked macaroni and cheese can be assembled before Thanksgiving.
Prepare the pasta and cheese sauce, transfer everything to a baking dish, cover tightly, and refrigerate.
Allow the dish to sit at room temperature briefly before baking and add a little extra cheese on top for a golden finish.
7. Make-Ahead Roasted Vegetables
Vegetables such as carrots, Brussels sprouts, sweet potatoes, and butternut squash can be chopped and prepared ahead.
For the freshest texture, roast them on Thanksgiving Day.
Having the vegetables washed, peeled, chopped, and seasoned ahead of time saves valuable kitchen time.
8. Make-Ahead Dinner Rolls

Dinner rolls are another excellent item to prepare ahead.
Depending on the recipe, rolls can often be prepared, shaped, and refrigerated before baking.
Warm freshly baked rolls shortly before dinner and serve with butter.
9. Make-Ahead Gravy
Gravy doesn’t need to wait until the turkey comes out of the oven.
A flavorful make-ahead gravy can be prepared using turkey or chicken stock and reheated before dinner.
Add turkey drippings on Thanksgiving Day if you have them available for an extra layer of flavor.
10. Make-Ahead Corn Casserole
Creamy corn casserole is a comforting Thanksgiving side that can be mixed and assembled ahead of time.
Keep it covered and refrigerated until you’re ready to bake.
The result is a warm, tender side dish that pairs beautifully with turkey and gravy.

How to Keep Make-Ahead Thanksgiving Sides Fresh
Use Airtight Containers
Store prepared foods in airtight containers whenever possible.
Label Everything
Write the dish name and reheating instructions on containers or foil-covered baking dishes.
Keep Cold Foods Refrigerated
Don’t leave prepared Thanksgiving dishes sitting at room temperature for extended periods.
Reheat Gently
Creamy dishes can separate if reheated too aggressively. Use moderate heat and stir when appropriate.
Refresh Before Serving
A little butter, fresh herbs, grated cheese, crispy onions, or freshly ground black pepper can make reheated dishes taste freshly prepared.
Tips for Hosting Thanksgiving
Don’t Make Everything Ahead
Some foods are better when prepared fresh. Roasted vegetables, crispy toppings, and freshly baked rolls are often best finished shortly before serving.
Create an Oven Schedule
Write down which dishes need the oven and their temperatures and cooking times.
This prevents multiple casseroles from competing for oven space.
Use Your Slow Cooker
Mashed potatoes, some vegetable sides, and gravy can often be kept warm in a slow cooker.
Prepare Serving Dishes Early
Set out serving bowls, spoons, and platters the night before.
Don’t Forget Refrigerator Space
If you’re preparing several dishes ahead, make sure you have enough room in the refrigerator.
How to Reheat Thanksgiving Side Dishes
Mashed potatoes: Reheat gently in a saucepan or slow cooker with a little milk, cream, or butter.
Stuffing: Reheat covered to prevent drying, then uncover near the end for a crisp top.
Green bean casserole: Reheat in the oven and add crispy onions near the end.
Sweet potato casserole: Bake until warmed through and the topping is golden.
Mac and cheese: Cover during most of reheating and uncover toward the end.
Gravy: Reheat gently on the stovetop, whisking occasionally.
Cranberry sauce: Serve chilled or warm gently in a saucepan.
