A rich and creamy sweet potato casserole, perfect for holiday gatherings, topped with toasted marshmallows.

Ingredients

Scale
  • 2 pounds sweet potatoes, peeled and cubed
  • 1/2 cup granulated sugar
  • 1/4 cup unsalted butter, softened
  • 1/4 cup milk
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • Pinch of salt
  • 1 cup mini marshmallows

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. Boil the sweet potato cubes in water until tender, about 15-20 minutes. Drain well.
  3. In a large bowl, mash the sweet potatoes until smooth.
  4. Add the granulated sugar, softened butter, milk, vanilla extract, cinnamon, nutmeg, and salt. Mix until well combined and creamy.
  5. Pour the sweet potato mixture into a greased 8×8 inch baking dish.
  6. Spread the mini marshmallows evenly over the top of the sweet potato mixture.
  7. Bake for 20-25 minutes, or until the marshmallows are golden brown and puffy.
  8. Let stand for a few minutes before serving.

Notes

  • For a pecan streusel topping instead of marshmallows, combine 1/2 cup chopped pecans, 1/4 cup brown sugar, 1/4 cup all-purpose flour, and 2 tablespoons melted butter. Sprinkle over the sweet potato mixture before baking.
  • This casserole pairs well with savory dishes and can be a comforting addition to your meal planning.
