Sweet Potato Casserole with Marshmallow

Sweet Potato Casserole with Marshmallow combines mashed sweet potatoes blended with butter, hot milk, and brown sugar, baked under a layer of mini marshmallows until lightly browned and puffy. The dish results in a creamy, sweet base with a toasted, melting marshmallow topping, making it a classic side dish often served during holiday meals or comfort food occasions.

Description

This Sweet Potato Casserole features peeled and simmered sweet potatoes mashed to a smooth consistency and mixed with melted butter, hot milk, and a small amount of brown sugar to enhance their natural sweetness. The mash is spread evenly in a baking dish and topped generously with mini marshmallows. Baking until the marshmallows puff up and turn a light golden gives the casserole a sweet, crisp topping that contrasts with the creamy sweet potato beneath.

The casserole is traditionally served as a side dish, especially at holiday dinners, offering a sweet alternative to savory sides. Its soft, smooth texture combined with the toasted marshmallow layer provides a familiar and comforting combination.

Varieties of orange-fleshed sweet potatoes like Beauregard or Garnet are recommended for their classic flavor. Only a modest amount of brown sugar is added, enough to enhance but not overpower the sweet potatoes' flavor. The marshmallow topping can be adjusted or substituted based on preference.

Ingredients

Servings
  • 5 pounds sweet potato peeled and cut into 1-inch pieces
  • salt
  • 1/2 cup butter melted (1 stick)
  • 1 cup milk hot
  • 1 tablespoon brown sugar
  • 10 ounces mini marshmallows

Instructions

  1. Adjust an oven rack to the middle position and preheat oven to 450 degrees.
  2. In a Dutch oven or large stockpot, add sweet potatoes and 1 tablespoon salt. Add cold water to cover sweet potatoes by 1 inch.
  3. Bring to boil, reduce heat, and simmer until sweet potatoes are tender and a fork can be easily slipped into the center, about 20 to 25 minutes. Drain well, tossing in colander to remove excess water.
  4. Wipe pot dry. Return sweet potatoes to pot and mash to a uniform consistency. Using a rubber spatula, fold in melted butter until just incorporated.
  5. Stir in hot milk and brown sugar until combined. Season to taste with salt (I like 1/4 teaspoon salt). Spread in the bottom of a 9-inch by 13-inch baking dish.
  6. Spread marshmallows evenly over the sweet potatoes. Bake until the marshmallows are lightly browned and puffy, about 5 minutes. Serve immediately.

Notes

  • Orange-fleshed varieties such as Beauregard, Covington, Garnet, and Jewel work best for traditional flavor.
  • A tablespoon of brown sugar adds subtle sweetness without overpowering the dish.
  • Use a full small bag of mini marshmallows for the topping to adequately cover a 9x13-inch baking dish.
  • Consider alternative toppings if preferred; see recipe FAQ for ideas.
