Description

This Sweet Potato Casserole with Marshmallows is a classic comforting dish featuring creamy mashed sweet potatoes topped with a crunchy pecan layer and golden toasted marshmallows. Perfect for holiday dinners or as a cozy side dish.


Ingredients

Scale

Sweet Potato Filling

  • 4 large sweet potatoes, peeled and chopped into large chunks
  • ½ cup unsalted butter
  • 1 cup brown sugar
  • ½ teaspoon salt
  • ½ teaspoon cinnamon
  • 1 teaspoon vanilla extract
  • ¼ teaspoon nutmeg

Pecan Topping

  • 4 tablespoons unsalted butter, melted
  • ⅓ cup brown sugar
  • 2 tablespoons all purpose flour
  • ½ teaspoon salt
  • 1 ¼ cups finely chopped pecan pieces

Marshmallow Layer

  • 10 oz mini marshmallows


Instructions

  1. Prepare Sweet Potatoes: Peel and cut the sweet potatoes into large chunks and place them into a large saucepan. Cover with water and bring to a boil.
  2. Boil Sweet Potatoes: Boil the sweet potatoes until they are fork tender and easily pierced, about 20-25 minutes. They should fall apart easily.
  3. Mash Filling: Drain the sweet potatoes and return them to the saucepan. Add the butter and mash with a potato masher until smooth. Add brown sugar, salt, cinnamon, vanilla extract, and nutmeg. Mix well until combined.
  4. Prepare Pecan Topping: In a separate bowl, stir together melted butter, brown sugar, all purpose flour, salt, and finely chopped pecans until thoroughly combined.
  5. Prepare Baking Dish: Grease a 9 by 13 inch baking dish with cooking spray to prevent sticking.
  6. Assemble Casserole: Spread the sweet potato filling evenly into the baking dish. Then spread the pecan topping evenly over the sweet potato layer.
  7. Add Marshmallows: Evenly distribute the mini marshmallows over the pecan topping layer.
  8. Bake: Bake in a preheated oven at 350 degrees Fahrenheit for 35 minutes, or until the casserole is bubbly and the marshmallows are golden brown. Watch closely towards the end to avoid burning.

Notes

  • Leftover casserole can be stored in an airtight container in the refrigerator for 4-5 days.
  • Use fresh sweet potatoes for best texture; canned sweet potatoes can alter flavor and consistency.
  • Toasting pecans before mixing enhances their flavor.
  • For a lighter version, reduce butter amounts or substitute with a lower-fat alternative.
  • If you prefer less sweetness, reduce brown sugar slightly in the filling or topping.
  • Keep a close eye on marshmallows in the last 5 minutes of baking to achieve a perfect golden brown without burning.
