Ingredients

Sweet Potato Base
  • 4 cups mashed sweet potatoes Vitamin-rich base (beta-carotene) with creamy texture.
  • 1/2 cup brown sugar Adds warm molasses sweetness and moisture.
  • 1/4 cup milk Helps create a silky, scoopable consistency.
  • 1/4 cup melted butter Adds richness and a golden finish.
  • 1 teaspoon vanilla extract Enhances sweetness and rounds flavors.
  • 2 large eggs Bind the mixture and give a slightly custardy structure.
  • 1/2 teaspoon salt Balances sweetness and lifts flavors.
Topping
  • 2 cups mini marshmallows Provide a nostalgic, toasted topping with soft chew.

Method

Preparation
  1. Preheat the oven to 350°F (175°C).
  2. In a large bowl, combine the mashed sweet potatoes, brown sugar, milk, melted butter, vanilla extract, eggs, and salt.
  3. Mix until the ingredients are well combined and the mixture is smooth and slightly glossy.
  4. Grease a 9x13-inch baking dish (or similar) and pour the sweet potato mixture into the dish. Smooth the top with a spatula.
Baking
  1. Bake the casserole for 25 minutes, uncovered, until it is set around the edges.
  2. Remove the casserole from the oven and evenly spread mini marshmallows across the surface.
  3. Return to the oven and bake an additional 10–15 minutes, or until the marshmallows are toasted and golden. Watch closely — marshmallows can brown quickly.
  4. Let the casserole sit for a few minutes before serving warm as a side dish.

Notes

For a different topping, substitute with streusel or toasted meringue. This casserole can be made ahead and refrigerated without marshmallows. To reduce sugar, lower the brown sugar and add cinnamon and nutmeg.
