Sweet Potato Casserole with Marshmallows


  • Author: OliviaBennett

Description

This cozy holiday classic takes humble sweet potatoes and transforms them into the star of your table. Creamy, lightly spiced, and crowned with a gooey, golden marshmallow topping, it’s a dish that tastes like a warm hug. Every bite brings nostalgia, comfort, and celebration—no holiday table feels complete without it.


Ingredients

Scale
  • 4 large sweet potatoes (about 3 lbs), peeled & cubed

  • ½ cup unsalted butter, melted

  • ½ cup packed brown sugar

  • ¼ cup milk (whole or 2%)

  • 2 large eggs, whisked

  • 1 tsp vanilla extract

  • ½ tsp cinnamon

  • ¼ tsp nutmeg

  • Pinch of salt

  • 3 cups mini marshmallows


Instructions

  • Prep: Preheat oven to 350°F (175°C). Grease a 9×13″ baking dish.

  • Cook potatoes: Boil sweet potatoes in salted water until fork-tender (≈15 min). Drain very well.

  • Mash & mix: Mash potatoes smooth. Mix in butter, brown sugar, milk, eggs, vanilla, cinnamon, nutmeg, and salt. Use a hand mixer for extra lightness.

  • Assemble: Spread mixture evenly in the baking dish. Top with marshmallows in a full, even layer.

  • Bake: 20–25 min, until marshmallows are golden and filling is bubbly.

  • Rest: Cool 5 min before serving for neater scoops.

Notes

  • Drain potatoes very well—extra water = runny casserole.

  • Bake in the middle of the oven to avoid burning marshmallows.

  • For nutty crunch, swap marshmallows for a pecan praline topping.

  • Make ahead: Prep filling up to 2 days in advance; add marshmallows before baking.
