Instructions
1. Cook the Sweet Potatoes:
- Preheat your oven to 350°F (175°C).
- Place the peeled and cubed sweet potatoes in a large pot of salted water. Bring to a boil and cook for 15-20 minutes, or until tender. Drain and transfer to a large mixing bowl.
2. Prepare the Sweet Potato Filling:
- Mash the sweet potatoes with 1/2 cup brown sugar, 1/2 tsp cinnamon, 1/8 tsp nutmeg, 1/4 cup melted butter, heavy whipping cream, and vanilla extract. Mix until smooth and creamy. Adjust seasoning as desired.
- Spread the sweet potato mixture evenly into a greased 9×13-inch baking dish.
3. Make the Streusel Topping:
- In a medium bowl, combine the flour, oats, 3/4 cup brown sugar, 1 tsp cinnamon, and 1/4 tsp nutmeg.
- Cut in the remaining 1/4 cup butter using a pastry cutter or your fingers until the mixture forms a crumbly texture.
4. Assemble the Casserole:
- Sprinkle the streusel topping evenly over the sweet potato layer.
- Top with marshmallows, either in a single layer or scattered, depending on your preference.
5. Bake:
- Bake in the preheated oven for 25-30 minutes, or until the marshmallows are golden brown and the casserole is bubbling around the edges.
6. Serve:
- Remove from the oven and let cool for 5 minutes before serving. Enjoy as a side dish or a dessert!
Notes
- Make Ahead: Prepare the sweet potato filling and streusel topping separately up to 1 day in advance. Assemble just before baking.
- Nut Option: Add 1/2 cup chopped pecans or walnuts to the streusel topping for added crunch.
- Lighter Version: Use half-and-half instead of heavy cream and reduce the brown sugar if desired.
