This easy sweet potato casserole is simple and yummy. My husband begs me for this dish. I got the recipe from his mother.
6 large sweet potatoes, peeled and cut into chunks
1 cup white sugar
½ cup brown sugar
2 tablespoons ground cinnamon
1 tablespoon butter, softened
1 cup miniature marshmallows, or as needed
Place sweet potatoes in a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender, about 20 minutes; drain.
Preheat the oven to 375 degrees F (190 degrees C). Grease a deep casserole dish.
Mash potatoes with a potato masher in a bowl until no large lumps remain. Stir in both sugars, cinnamon, and butter until well combined, then transfer to the prepared casserole dish. Cover with a layer of miniature marshmallows.
Bake in the preheated oven until marshmallows are browned, about 30 minutes.
