Ingredients

Scale

Main Ingredients:

  • 4 large sweet potatoes
  • 1/2 cup milk
  • 1/4 cup unsalted butter
  • 1 cup mini marshmallows
  • 1/2 cup chopped pecans

Seasoning and Flavor Enhancers:

  • 2 tbsp brown sugar
  • 1 tsp ground cinnamon
  • 1/2 tsp vanilla extract
  • 1/4 tsp salt
  • 1/8 tsp ground nutmeg

Gravy and Topping Components:

  • 1/4 cup heavy cream
  • 2 tbsp maple syrup
  • 1 tbsp cornstarch
  • 1/4 cup water

Instructions

  1. Peel and chop sweet potatoes into uniform cubes, ensuring even cooking and smooth texture.
  2. Boil sweet potato cubes in salted water for 15-20 minutes until fork-tender and easily mashed.
  3. Drain potatoes thoroughly and return to pot, allowing excess moisture to evaporate.
  4. Mash potatoes with butter, milk, brown sugar, cinnamon, vanilla extract, salt, and nutmeg until creamy and well-integrated.
  5. Transfer mashed sweet potato mixture to a greased baking dish, spreading evenly with a spatula.
  6. Prepare marshmallow gravy by whisking heavy cream, maple syrup, cornstarch, and water in a small saucepan over medium heat.
  7. Simmer gravy for 3-4 minutes until thickened and glossy, stirring constantly to prevent burning.
  8. Drizzle half the marshmallow gravy over mashed sweet potatoes.
  9. Sprinkle chopped pecans across the surface for added crunch and nutty flavor.
  10. Top casserole with mini marshmallows, covering entire surface.
  11. Bake in a preheated 375°F oven for 20-25 minutes until marshmallows are golden brown and puffy.
  12. Remove from oven and let rest for 5 minutes before serving.
  13. Drizzle remaining marshmallow gravy over the casserole just before serving for extra indulgence.

Notes

  • Achieve consistent cooking by cutting sweet potatoes into equal-sized cubes, preventing uneven texture and ensuring uniform doneness.
  • Control moisture levels by thoroughly draining boiled potatoes and allowing them to sit in the pot, helping create a smoother, less watery mash.
  • Enhance flavor complexity by toasting pecans briefly before sprinkling on top, which intensifies their nutty profile and adds deeper roasted notes.
  • Accommodate dietary restrictions by substituting dairy milk with almond or oat milk, and using coconut oil instead of butter for a vegan-friendly version of the casserole.
