Description

A classic and comforting Sweet Potato Casserole featuring a creamy mashed sweet potato base mixed with warm spices and brown sugar, topped with a crunchy pecan streusel and melted mini marshmallows, baked to golden perfection. Perfect as a side dish for holiday meals or any cozy dinner.


Ingredients

Scale

Sweet Potato Layer

  • 3 ½ pounds sweet potatoes (peeled and cut into large chunks)
  • ½ cup brown sugar
  • ½ cup unsalted butter (melted)
  • 1 teaspoon pumpkin pie spice
  • 1 teaspoon vanilla extract
  • ½ teaspoon salt

Pecan Topping

  • 1 cup pecans (chopped)
  • ¼ cup unsalted butter (melted)
  • ¼ cup brown sugar (packed)
  • 3 tablespoons all-purpose flour

Additional Topping

  • 5 ounces mini marshmallows


Instructions

  1. Prepare Sweet Potatoes: Boil the peeled and chunked sweet potatoes in a large pot of water until they are tender and easily pierced with a fork, about 15-20 minutes. Drain well to remove excess water.
  2. Mash and Mix: Transfer the drained sweet potatoes to a large bowl and mash them until smooth. Stir in the brown sugar, melted butter, pumpkin pie spice, vanilla extract, and salt until the mixture is well combined and creamy.
  3. Assemble Sweet Potato Layer: Pour the sweet potato mixture evenly into a baking dish, spreading it out smoothly to form the base layer of the casserole.
  4. Make Pecan Topping: In a separate bowl, combine the chopped pecans, melted butter, brown sugar, and all-purpose flour. Mix the ingredients together until they form a crumbly topping mixture.
  5. Top Sweet Potatoes: Sprinkle the pecan topping evenly over the sweet potato layer in the baking dish.
  6. Add Marshmallows: Evenly distribute the mini marshmallows over the pecan topping for a sweet, gooey finish.
  7. Bake: Preheat your oven to 350°F (175°C). Place the casserole on the middle rack and bake for 20 minutes, or until the marshmallows are golden brown and the filling is heated through.

Notes

  • For a smoother texture, you can use a hand mixer to mash the sweet potatoes.
  • Make sure to drain the sweet potatoes thoroughly to avoid a watery casserole.
  • Toast the pecans lightly if you prefer a deeper nutty flavor before mixing with the topping ingredients.
  • Keep an eye on the marshmallows during baking to prevent burning—cover with foil if they brown too quickly.
  • This dish can be prepared a day ahead and baked just before serving for convenience.
