Sweet Potato Casserole with Marshmallows

Sweet potato casserole with marshmallows blends creamy mashed sweet potatoes with a sugary marshmallow topping that browns in the oven. The dish offers a smooth, mildly sweet base enriched by milk, butter, brown sugar, and eggs. Toasting the mini marshmallows adds a light, crisp layer contrasting with the tender potato filling. This casserole is often made for gatherings or holiday meals, providing a comforting, sweet side dish that can be prepared ahead of time and baked when needed.

Description

Sweet Potato Casserole with Marshmallows combines peeled and cubed sweet potatoes cooked until tender, then mashed smooth with milk, brown sugar, butter, eggs, salt, and vanilla extract. The mixture is poured into a greased baking dish and topped with mini marshmallows that toast and brown during baking, creating a lightly crisp and sweet topping. The marshmallows provide a delicate textural contrast to the creamy and dense sweet potato base.

Baking at 350°F allows the casserole to heat through while giving the marshmallows a golden finish. The flavors balance mild sweetness from the potatoes and sugar with vanilla notes, creating a familiar and satisfying side dish often served at festive meals.

The casserole can be prepared ahead by assembling the sweet potato mixture and refrigerating it without marshmallows. When ready, topping with marshmallows and baking brings freshness to the toasted topping and warmth to the dish, making it convenient for planning ahead during holidays or events.

Ingredients

Servings
  • 3 to 4 pounds sweet potato peeled and cubed
  • 1/2 cup milk whole, 2%, or 1%
  • 1/2 cup brown sugar light or dark
  • 4 tablespoons butter salted
  • 2 large egg
  • 1/2 teaspoon salt
  • 1/2 teaspoon vanilla extract
  • 10 ounces mini marshmallows

Instructions

  1. Preheat the oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish or a 3-quart casserole dish.
  2. Fill a 5-quart pot 2/3rds full with water and bring to a boil over high heat. Peel and cube 3 to 4 pounds sweet potatoes. Add the cubed sweet potatoes to the boiling water, return to a boil, then reduce heat to low. Simmer until the sweet potatoes are tender, about 15-20 minutes. Drain and set aside.
  3. Transfer the sweet potatoes to a large mixing bowl and add 1/2 cup milk, 1/2 cup brown sugar, 4 tablespoons salted butter, 2 large eggs , 1/2 teaspoon salt, and 1/2 teaspoon vanilla extract. Use a hand mixer to blend until smooth and creamy.
  4. Transfer the sweet potato mixture to the prepared baking dish, spreading it evenly. Sprinkle 10 ounces mini marshmallows evenly over the top.
  5. Bake for 25-30 minutes, until the marshmallows are toasted and golden brown.

Notes

  • To prepare in advance, assemble the casserole without marshmallows and refrigerate. Add marshmallows just before baking.
  • Use mini marshmallows for even melting and browning on top.
