Sweet Potato Casserole Marshmallow Recipe

These Sweet Potatoes with marshmallows is my favorite version of the slightly sweet classic holiday side dish.  It’s filled with warmed mashed potatoes, brown sugar, cinnamon and nutmeg and topped with ooey gooey mini marshmallows.

Ingredients

  • 4 lbs Sweet Potatoes peeled and cut into 1" pieces
  • 1 cup Butter
  • 1 Cup Dark Brown Sugar
  • ½ teaspoon Ground Cinnamon
  • 1 pinch Nutmeg
  • 3 Cups Mini Marshmallows Reserve half to top casserole before baking

Instructions

  • Preheat oven to 400 degrees.
  • Wash and peel the sweet potatoes, cut into 1" pieces and add to a large pot. Fill the pot with water to cover the potatoes and bring to a boil. Continue to boil for 15-20 minutes, or until they are fork-tender.
  • When the sweet potatoes have finished cooking, put them back into the cooking pot and use a potato masher to mash the sweet potatoes until they are smooth.
  • In a medium-sized saucepan over medium heat, melt the butter, then add the brown sugar, cinnamon and nutmeg. Bring to boil and boil for 30 seconds, then reduce the heat slightly, add 1 ½ cups of the marshmallows and continue to cook and stir until the marshmallows are melted.
  • Pour the butter and marshmallow mixture into the sweet potatoes and stir until combined. Spread this sweet potato mixture into a 9 x 13" baking dish and top evenly with the remaining 1 ½ cups mini marshmallows.
  • Bake in a preheated oven for 15 minutes, or until the tops of the marshmallows are golden brown. Remove from the oven and let cool slightly before serving. Enjoy!
