Ingredients

Sweet Potatoes

  • 5 tablespoons unsalted butter, melted
  • 5-6 large sweet potatoes
  • 2 tablespoons dark brown sugar
  • 1/4 teaspoon ground nutmeg
  • 1/4 teaspoon ground cinnamon
  • 1/8 teaspoon cayenne pepper
  • 3 eggs, room temperature
  • 1 teaspoon vanilla
  • 1/2 teaspoon Kosher salt
  • 1/2 teaspoon freshly ground black pepper

Marshmallow Meringue

  • 4 egg whites, room temperature
  • 1/2 cup granulated sugar
  • 1/2 teaspoon cream of tartar
  • 1 teaspoon vanilla

Instructions

  1. Preheat oven to 375°F.

Sweet Potatoes

  1. Place sweet potatoes on a foil-lined baking sheet, and bake until soft, (about 70-80 minutes).
  2. Pierce the top of each potato with a knife and let cool for 15-20 minutes, or until the sweet potatoes are cool enough to handle.
  3. Scoop out the inside of each sweet potato (discard the skins) and place the contents into the bowl of a food processor.
  4. Add brown sugar, nutmeg, cinnamon, cayenne pepper, eggs, vanilla, salt, and pepper. Blend until smooth.

  5. Pour mixture into a greased 11x7 casserole dish.

  6. Transfer casserole dish to the oven and bake for 20-25 minutes, or until sweet potatoes are set. While sweet potatoes are baking, prepare the marshmallow meringue.

Marshmallow Meringue

  1. Bring a saucepan filled with water to a boil.
  2. Reduce heat to simmer.
  3. In a medium bowl, add egg whites, sugar, and cream of tartar. Whisk together.
  4. Place the bowl over the saucepan and cook, whisking constantly, until the sugar is completely dissolved (about 3 to 4 minutes)
  5. Remove from heat.

  6. With an electric mixer, beat the mixture until smooth and soft peaks form (about 5-6 minutes). If peaks do not form after 6 minutes, slowly add in 1 teaspoon of sugar at a time, continue mixing and repeat until it begins to firm up.

  7. Add in the remaining 1 teaspoon of vanilla.

Assemble

  1. Once the sweet potatoes have baked, change the oven temperature from 375° F to Broil.

  2. Carefully top the cooked sweet potatoes with the marshmallow meringue in an even layer (the pan will be hot).

  3. Broil until marshmallow meringue is browned (30 seconds to 2 minutes). The meringue should be golden brown.

  4. Serve hot.
