Ingredients

Scale

For the Sweet Potato Base:

  • 3 cups mashed sweet potatoes (about 3–4 medium sweet potatoes, cooked and peeled)

  • ½ cup granulated sugar (adjust to taste)

  • ½ tsp salt

  • ½ tsp ground cinnamon

  • ¼ tsp ground nutmeg

  • 2 tbsp unsalted butter, melted

  • ½ cup milk

  • 1 tsp vanilla extract

For the Topping:

  • 1½ cups mini marshmallows (or large marshmallows cut in halves)

  • Optional: ¼ cup chopped pecans or walnuts for crunch


Instructions

1. Prepare Sweet Potatoes

  • Peel and cube sweet potatoes.

  • Boil in water for 15–20 minutes until tender, or roast at 400°F (200°C) for 25–30 minutes.

  • Drain and mash until smooth.


2. Mix the Base

  • In a large bowl, combine mashed sweet potatoes, sugar, salt, cinnamon, nutmeg, butter, milk, and vanilla.

  • Mix until smooth and creamy.


3. Assemble the Casserole

  • Preheat oven to 350°F (175°C).

  • Spread sweet potato mixture evenly in a greased 8×8-inch baking dish (or similar size).

  • Sprinkle marshmallows evenly over the top.

  • Optional: sprinkle chopped nuts over marshmallows for extra texture.


4. Bake

  • Bake uncovered for 20–25 minutes, until marshmallows are melted and golden brown on top.

  • If marshmallows brown too quickly, loosely cover with foil in the last 5 minutes.


5. Serve

  • Serve warm as a comforting side dish.

  • Pairs beautifully with turkey, ham, or roasted chicken.
