Mashed Sweet Potatoes with Marshmallows

Step 1
Gather all ingredients.

Step 2
Preheat the oven to 350 degrees F (175 degrees C).

Step 3
Place sweet potatoes into a large pot and cover with water; bring to a boil. Reduce the heat to medium-low and simmer until tender, about 20 minutes.

Step 4
Drain potatoes and transfer to a baking sheet.

Step 5
Bake sweet potatoes in the preheated oven until dried, 3 to 4 minutes; transfer to a mixing bowl. Keep the oven on.

Step 6
Mash sweet potatoes with a potato masher until no large lumps remain. Add brown sugar, allspice, and cinnamon; continue mashing until potatoes are evenly seasoned.

Step 7
Spoon mixture into a casserole dish and spread marshmallows in an even layer over top.

Step 8
Bake in the oven until marshmallows just begin to brown, 10 to 15 minutes. Turn on the broiler and broil for 1 minute.
