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

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 when pierced with a fork, about 20-25 minutes. Drain well to avoid excess moisture.
  2. Mash and mix: Mash the drained sweet potatoes in a large bowl. Add brown sugar, melted butter, pumpkin pie spice, vanilla extract, and salt. Mix until fully combined and smooth.
  3. Assemble sweet potato layer: Pour the sweet potato mixture into a greased baking dish, spreading it out evenly for a flat surface.
  4. Prepare pecan topping: In a separate bowl, combine chopped pecans, melted butter, brown sugar, and all-purpose flour. Mix until crumbly and evenly incorporated.
  5. Add topping and marshmallows: Sprinkle the pecan mixture evenly over the sweet potato layer. Then, evenly distribute the mini marshmallows on top of the pecan topping.
  6. Bake: Preheat the oven to 350°F (175°C). Bake the casserole for about 20 minutes or until the topping is golden brown and the marshmallows are melted and lightly toasted.
  7. Serve: Remove from oven and let cool slightly before serving to allow the casserole to set.

Notes

  • Use fresh sweet potatoes for the best texture and flavor.
  • Be careful not to overcook the sweet potatoes in water to avoid sogginess.
  • The pecan topping adds a crunchy contrast to the creamy sweet potatoes.
  • If you prefer, substitute mini marshmallows with marshmallow fluff spread after baking for less browning.
  • This casserole pairs wonderfully with roasted meats, especially during the holidays.
