Ingredients You’ll Need

  • 4 cups sweet potatoes, peeled and cubed
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar
  • 1/2 cup unsalted butter, melted
  • 1/4 cup milk (or any dairy alternative)
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/4 teaspoon salt
  • 2 cups mini marshmallows
  • Optional topping: 1/2 cup chopped pecans or graham cracker crumbs

Step‑By‑Step Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with butter or cooking spray.
  2. Cook the sweet potatoes: Boil cubed sweet potatoes in a large pot of water for 15–20 minutes until tender. Drain well.
  3. Mash the sweet potatoes: In a large mixing bowl, mash the cooked sweet potatoes until smooth.
  4. Mix in flavorings: Stir in granulated sugar, brown sugar, melted butter, milk, vanilla extract, cinnamon, nutmeg, and salt until fully combined.
  5. Transfer to baking dish: Spread the sweet potato mixture evenly into the prepared baking dish.
  6. Add the marshmallow topping: Sprinkle mini marshmallows evenly over the top. Add pecans or graham cracker crumbs if desired.
  7. Bake: Place in the preheated oven and bake for 20–25 minutes, or until marshmallows are golden brown and slightly toasted.
  8. Serve warm: Let cool for a few minutes, then serve as a comforting side dish.

Helpful Notes & Tips

  • Consistency tip: If your mashed sweet potatoes seem too thick, add 1–2 tablespoons of milk at a time to reach the desired texture.
  • Storage: Cover leftovers and refrigerate for up to 4 days. Reheat gently in the oven to restore the marshmallow topping’s softness.
  • Sweetness control: Adjust sugar according to taste—some prefer less brown sugar for a milder flavor.

Recipe Variations

  1. Nut-free option: Skip pecans or graham cracker crumbs if you have nut allergies.
  2. Dairy-free option: Use coconut milk or almond milk and a dairy-free butter substitute.
  3. Spiced twist: Add a pinch of ginger or allspice for extra warmth and seasonal flavor.

Serving Suggestions

  • Pair with roast turkey or chicken for a classic holiday meal.
  • Serve alongside green beans or a crisp salad to balance the sweetness.
  • Garnish with extra toasted marshmallows or a sprinkle of cinnamon before serving.
