Ingredients

Scale
  • 4 cups mashed sweet potatoes (about 4 large sweet potatoes)
  • ½ cup white sugar
  • 2 eggs, beaten
  • ½ teaspoon salt
  • 4 tablespoons butter, softened
  • ½ cup milk
  • ½ teaspoon vanilla extract
  • 2 cups mini marshmallows

Optional Additions:

  • A sprinkle of cinnamon or nutmeg
  • Brown sugar for extra flavor
  • Chopped pecans for crunch

Instructions

  1. Preheat oven: Set oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
  2. Cook sweet potatoes: Peel and cube sweet potatoes, then boil until fork-tender, about 15–20 minutes. Drain and mash until smooth.
  3. Mix filling: In a large bowl, combine mashed sweet potatoes with sugar, eggs, salt, butter, milk, and vanilla. Mix until smooth and creamy.
  4. Bake the base: Pour the mixture into the prepared baking dish and bake for 25–30 minutes, until set and slightly puffed.
  5. Add topping: Remove from oven and evenly top with mini marshmallows.
  6. Toast marshmallows: Return to oven and bake for another 10–15 minutes, or until marshmallows are golden and gooey.
  7. Serve: Let cool slightly before serving. Enjoy this cozy, sweet, and festive side dish!

Notes

  • Use fresh sweet potatoes for the best flavor — avoid canned yams if possible.
  • Roast sweet potatoes instead of boiling for a deeper caramelized flavor.
  • Keep an eye on the marshmallows while toasting to prevent burning.
  • Make ahead: prepare filling up to 2 days in advance and bake before serving.
  • Store leftovers in the fridge for up to 5 days or freeze without marshmallows for 2 months.
