Main ingredients

  • 4 medium medium sweet potatoes, peeled and cubed (about 3–4 lb total)
  • 1/2 cup brown sugar (light or dark) Reduce to 1/3 cup for less sweetness.
  • 1/2 cup milk (dairy or unsweetened plant milk) For dairy-free, use almond or oat milk.
  • 1/4 cup butter, melted (or vegan butter) Use vegan butter for a dairy-free option.
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon Adjust to taste.
  • 1/4 teaspoon ground nutmeg Adjust to taste.
  • 1 cup mini marshmallows (optional) Do not freeze; add before serving.
  • 1/2 cup pecans or walnuts, chopped (optional) For extra crunch, toast in a dry skillet for 3–4 minutes.

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C). Grease a 9x13-inch or similar baking dish.
  • Place peeled, cubed sweet potatoes in a large pot and cover with cold water. Bring to a boil and simmer until tender when pierced with a fork, about 15–20 minutes.
  • Drain the potatoes thoroughly and return them to the hot pot for a minute to evaporate residual moisture. Mash until smooth with a potato masher or hand mixer.
  • In a large bowl, combine the mashed sweet potatoes with brown sugar, milk, melted butter, vanilla, cinnamon, and nutmeg. Stir until evenly blended and smooth.
  • Transfer the mixture to the prepared baking dish, smoothing the top. If using, sprinkle the mini marshmallows and chopped nuts evenly over the surface.

Baking

  • Bake for 25–30 minutes, until heated through and the marshmallows are golden brown (if using). Tenting with foil if marshmallows brown too quickly.

Notes

For a richer mash, use whole milk or a splash of cream. This casserole is perfect paired with roasted turkey, pork, or grilled chicken. It can also be frozen; omit marshmallows if freezing.
