  • Total Time: 55 minutes
  • Yield: 8 servings

Ingredients

Sweet Potato Mixture

  • 3 pounds sweet potatoes, peeled and roughly cubed
  • 1 cup brown sugar
  • 3 tablespoons butter, melted
  • 1 1/2 teaspoons ground cinnamon
  • 1/2 teaspoon kosher salt
  • 1/4 to 1 cup milk, added as needed for desired consistency

Topping

  • 2 cups mini marshmallows

Instructions

  1. Preheat the Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole later.
  2. Cook Sweet Potatoes: Bring a large pot of salted water to a boil, then reduce to medium-low heat and add the cubed sweet potatoes. Boil until the potatoes are fork-tender, about 20 minutes. Drain thoroughly.
  3. Mash Sweet Potatoes: Mash the cooked sweet potatoes using a potato masher until smooth. For an extra creamy texture without lumps, use a hand mixer to beat the potatoes.
  4. Mix Ingredients: Stir in the brown sugar, melted butter, ground cinnamon, and kosher salt until fully combined. Gradually add milk, a little at a time, until you reach your desired consistency—smooth and creamy but not runny.
  5. Prepare Casserole Dish: Lightly spray an 11 x 7-inch medium casserole baking dish with nonstick cooking spray. Evenly spread the sweet potato mixture into the dish.
  6. Add Marshmallow Topping: Sprinkle the 2 cups of mini marshmallows in an even layer over the sweet potato mixture.
  7. Bake: Place the casserole in the preheated oven and bake for 20-25 minutes, or until the marshmallows are melted and golden brown on top.
  8. Cool and Serve: Remove from oven and let the casserole cool for 5-10 minutes before serving to allow it to set slightly.

Notes

  • For a smoother texture, use a hand mixer when mashing the sweet potatoes.
  • Adjust milk quantity to achieve your preferred mashed sweet potato consistency.
  • Toasting marshmallows under a broiler for 1-2 minutes can speed up browning, but watch closely to avoid burning.
  • This dish can be prepared ahead and baked just before serving for convenience.
  • Use kosher salt or sea salt for best flavor balance.
