Sweet potato casserole is a classic Thanksgiving side dish. Sometimes you will find it topped with mini marshmallows or nuts as in this recipe. This sweet side dish compliments the robust stuffing, rich gravy, and savory turkey. Baked sweet potatoes are mashed with aromatic spices like cinnamon, ginger, and nutmeg (a little cayenne pepper wouldn't hurt either) that makes for a sweet and spicy side. If you can't decide which topping you want, add them both! Sweet potato casserole is a side dish that everyone at the table will love.
