Description

This classic Thanksgiving side dish features creamy whipped sweet potatoes topped with a buttery brown sugar streusel and toasted mini marshmallows. It’s a comforting and indulgent addition to any holiday table.


Ingredients

Scale

For the Sweet Potato Base:

  • 3 cups mashed sweet potatoes (about 3 large sweet potatoes)

  • ½ cup sugar

  • 2 large eggs

  • ½ cup melted butter

  • 1 teaspoon vanilla extract

  • ⅓ cup milk

  • ¼ teaspoon salt

For the Brown Sugar Streusel Topping:

  • ⅓ cup melted butter

  • ½ cup brown sugar

  • ⅓ cup all-purpose flour

  • 1 cup chopped pecans

For the Marshmallow Magic:

  • 1 ½ to 2 cups mini marshmallows


Instructions

  • Bake the Sweet Potatoes: Preheat oven to 400°F (204°C). Place sweet potatoes on a baking sheet and bake for about 45 minutes, or until tender. Larger sweet potatoes may require up to 1 hour.

  • Prepare the Filling: Once cool enough to handle, scoop out the flesh of the sweet potatoes into a mixing bowl. Add melted butter, brown sugar, milk, egg, maple syrup, cinnamon, and vanilla extract. Whip until smooth and creamy.

  • Make the Streusel: In a separate bowl, combine softened butter, brown sugar, and flour. Mix until crumbly.

  • Assemble the Casserole: Preheat oven to 350°F (177°C). Spread the sweet potato mixture evenly in a greased 9×9-inch baking dish. Sprinkle the streusel over the top.

  • Bake: Bake for 28–32 minutes, or until the casserole is heated through and the streusel is golden.​

  • Add Marshmallows: Remove from oven and sprinkle mini marshmallows over the top. Return to oven and bake for an additional 4–5 minutes, or until marshmallows are toasted. For a more toasted top, place under the broiler for 1–2 minutes, watching closely to prevent burning.​

Notes

  • Pan Size: This recipe fills a 9×9-inch baking dish. For a 9×13-inch dish, multiply the recipe by 1.5 or double it.​

  • Make Ahead: The sweet potato filling and streusel can be prepared ahead of time and stored separately in the refrigerator. Assemble and bake when ready to serve.​

  • Variations: For added texture and flavor, consider adding chopped pecans to the streusel topping.​
