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
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 9x9-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 9x9-inch baking dish. For a 9x13-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.
