Oven Candied Sweet Potatoes

• 4 - 5 medium sweet potatoes, scrubbed
• 1/3 cup packed brown sugar
• 1/4 cup butter or margarine
• 1/2 teaspoon salt
• 3/4 cup tiny marshmallows

Remove ends of sweet potatoes and place them in a pot. Cover with water and bring to a boil. Simmer about 30 minutes until tender. Drain, peel and slice 1/2" slices. Cover the bottom of an 8-inch square pan with half of the sweet potatoes. Sprinkle with half of the brown sugar, butter, and salt. Repeat the layer of sweet potatoes, brown sugar, butter, and salt. Bake for 30 minutes at 375 degrees. Sprinkle with marshmallows. Bake about 5 minutes more or until browned.
