Slice sweet potatoes into 1/4 inch round slices. Arrange potatoes in a lightly greased baking dish (approx. 13”x9”x2”).
Mix brown sugar, cinnamon, and pecans in a bowl. Sprinkle each layer of potatoes with the mixture. Pour 3/4 cup melted butter over potatoes evenly. Cover and back at 375°F for 30 minutes.
Remove, and baste with remaining 1/4 cup butter. Cover and continue baking for 30 minutes. (If transporting dish, stop here and continue last step at remote location – warm 5-10 minutes in oven before adding marshmallows).
Remove, sprinkle marshmallows evenly on top and continue baking without cover for 5 minutes.
