Method
Preparation
- Preheat the oven to 350°F and butter a 9x13 baking dish.
- In a large bowl, combine the warm mashed sweet potatoes, softened butter, milk, brown sugar, eggs, vanilla, cinnamon, nutmeg, and salt. Stir until smooth but do not overmix.
- Spread the mash evenly in the prepared baking dish.
- In a separate bowl, mix together the brown sugar, flour, chopped pecans, cinnamon, salt, and melted butter until it forms a crumbly mixture.
- Sprinkle the streusel topping over the mashed sweet potatoes.
Baking
- Bake for approximately 30 to 35 minutes until the edges are set and the topping is golden.
- If using marshmallows, bake the casserole uncovered for 25 minutes. Then, top with mini marshmallows and bake for an additional 8 to 10 minutes until toasted.
Serving
- Let the casserole sit for 10 minutes before serving so it cuts nicely and the flavors settle.
Notes
Make-ahead: Assemble the mash and topping separately up to 2 days ahead and keep them covered in the fridge. Top and bake the day of serving. Leftovers can be refrigerated and reheated; it also freezes well for up to a month.
