11 Sweet Potato Casseroles to Add to Your Thanksgiving Menu

It wouldn't be a proper, all-American Thanksgiving menu without roast turkey, creamy mashed potatoes, cornbread or buttery biscuits, pecan pie, and sweet potato casserole! Whether you like to cover sweet potatoes in marshmallows or a nutty brown sugar crumble, sweet potato casserole is a staple for Thanksgiving. Below, we're sharing exactly how to make it, plus several delicious variations including delicious sweet potato gratin recipes.

A basic sweet potato casserole is made with peeled and cooked sweet potatoes that are mashed before being mixed with milk or cream, butter, spices such as ground cinnamon or nutmeg, and salt. The mash is then transferred to a baking dish, topped with mini marshmallows, breadcrumbs, or a brown sugar crumble, and baked until puffy and the topping has lightly browned. This essential sweet side dish is a delicious counterpoint to other rich, savory foods often found on the Thanksgiving table such as turkey covered in gravy, green bean casserole, and cranberry sauce. If you'd like to prepare this classic version, you can make the sweet potato mixture in advance, which cuts down on valuable prep time on Thanksgiving Day. Looking for something a bit sweeter? Sweet Potato-Coconut Casserole calls for both coconut milk and sweetened shredded coconut, which is an extra-special side dish for the holiday.

Sweet potato casseroles can be savory, too. Do you want to spice things up? Try this Southwestern Sweet-Potato Gratin, a Tex-Mex twist on the classic potato side dish. It's topped with all the fixins'—grated Monterey Jack cheese, fresh Cotija cheese, fresh cilantro, and crushed tortilla chips for a surprising twist.
