A comforting sweet potato casserole topped with golden toasted marshmallows, perfect for holiday gatherings or cozy family dinners. This easy recipe combines creamy sweet potatoes with warm spices and a sweet, crunchy marshmallow topping.

Ingredients

Scale
  • 4 medium sweet potatoes (about 2 pounds or 900 grams), peeled and cubed
  • 1/2 cup (115 grams) unsalted butter, softened
  • 1/3 cup (65 grams) brown sugar, packed
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1 teaspoon vanilla extract
  • 1/4 cup (60 ml) milk (whole or 2%, or dairy-free alternative)
  • 1/2 teaspoon salt
  • 2 cups large marshmallows (about 50 marshmallows)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with butter or non-stick spray.
  2. Place peeled and cubed sweet potatoes in a large pot. Cover with cold water and add a pinch of salt. Bring to a boil and cook for 15-20 minutes, or until tender when pierced with a fork.
  3. Drain the sweet potatoes well and return them to the pot or a large mixing bowl. Mash until smooth but still slightly textured using a potato masher or electric mixer.
  4. Stir in softened butter, brown sugar, ground cinnamon, ground nutmeg, vanilla extract, milk, and salt until well combined and creamy.
  5. Spread the sweet potato mixture evenly into the prepared baking dish and smooth the top with a spatula.
  6. Scatter marshmallows evenly over the top of the sweet potatoes.
  7. Bake for 25-30 minutes, or until the sweet potato mixture is heated through and marshmallows are melted and puffed.
  8. Turn the oven to broil and broil the casserole for 2-4 minutes until marshmallows are toasted and caramelized. Keep the oven door slightly ajar and watch closely to avoid burning.
  9. Let the casserole cool for 5 minutes before serving.

Notes

Do not overboil sweet potatoes to avoid mushy texture. Use room temperature butter and milk for easier mixing. Watch marshmallows closely when broiling to prevent burning. For a fluffier topping, add mini marshmallows on top before baking. The casserole can be prepared ahead and refrigerated for up to 24 hours before baking.
