Sweet potato casserole is Thanksgiving's most debated dish—is it a side or a dessert? This version settles the argument by being absolutely both, with a pillowy marshmallow crown.

Why This Recipe Works

Whipping the sweet potatoes with butter and cream makes them impossibly smooth, while baking the marshmallow topping until just golden gives you both gooey and toasty textures.

Ingredients

  • 4 lbs sweet potatoes, peeled and cubed
  • 1/2 cup butter, softened
  • 1/3 cup heavy cream
  • 1/3 cup brown sugar
  • 1 tsp cinnamon and 1/4 tsp nutmeg
  • 1 bag (10 oz) mini marshmallows

Instructions

  1. 1

    Boil sweet potatoes in salted water until very tender, about 15 minutes. Drain well.

  2. 2

    Mash or whip sweet potatoes with butter, cream, brown sugar, cinnamon, nutmeg, 1 tsp vanilla, and 1/2 tsp salt until smooth.

  3. 3

    Spread the sweet potato mixture into a buttered 9x13 baking dish.

  4. 4

    Bake at 350°F for 15 minutes until heated through.

  5. 5

    Cover the top with mini marshmallows and return to the oven for 8-10 minutes, or broil 2-3 minutes, until marshmallows are golden and toasted.

Serving Suggestions

Ways to Serve This Dish

  • Serve with a fresh side salad for a balanced meal

  • Pair with your favorite grain or bread on the side

  • Garnish with fresh herbs for a beautiful presentation

Substitutions

Marshmallow toppingPecan streusel (pecans, brown sugar, flour, butter)

A crunchy, less sweet alternative

Heavy creamOrange juice for a brighter, lighter version

Adds a citrus note that pairs beautifully with sweet potato

Tips & Storage

Pro Tips

  • Watch the marshmallows closely under the broiler—they go from perfect to charred in seconds.

  • For a pecan streusel alternative, mix 1 cup pecans with 1/3 cup flour, 1/3 cup brown sugar, and 3 tbsp butter.

Storage

Refrigerate without marshmallow topping up to 3 days. Add marshmallows before reheating.

Reheating

Reheat at 350°F for 20 minutes, add fresh marshmallows, and broil until golden.

Frequently Asked Questions

Can I make it ahead?
Prepare the sweet potato base up to 2 days ahead. Add marshmallows and bake day-of.
Marshmallows or pecan streusel?
Both are classic—marshmallows are more indulgent, streusel adds crunch. Some do both.
