For the Marshmallow Topping
2 1/2cupsmini marshmallows
Instructions
Step 1: Roast the Sweet Potatoes
Preheat your oven to 400°F. Pierce two large sweet potatoes a few times with a fork and place them on a foil-lined baking sheet. Roast for about 45-50 minutes or until fork-tender. Let cool, peel, and mash until smooth. You’ll need 2 cups of mashed sweet potato for the filling.
Roasting enhances the natural sugars and gives a caramelized depth of flavor you won’t get from boiling.
Step 2: Prepare the Crust (or Use Store-Bought)
In a mixing bowl, whisk together the flour and salt. Cut in the cold butter using a pastry blender or two forks until the mixture resembles coarse crumbs. Add ice water, 1 tablespoon at a time, mixing just until the dough comes together. Form into a disk, wrap in plastic, and chill for 30 minutes.
Roll out the chilled dough on a floured surface and fit into a 9-inch deep-dish pie plate. Crimp the edges and refrigerate while you make the filling.
Step 3: Make the Filling
Preheat the oven to 350°F. In a large bowl, combine mashed sweet potatoes, brown sugar, eggs, evaporated milk, melted butter, vanilla, cinnamon, nutmeg, and salt. Mix until smooth using a hand mixer or whisk vigorously.
Pour the filling into the chilled pie crust and smooth the top with a spatula.
Step 4: Bake the Pie
Place the pie on the center rack of your preheated oven and bake for 45 to 50 minutes, or until the filling is set and no longer jiggles in the center. If the crust begins to brown too quickly, cover the edges with foil or a pie shield.
Let the pie cool on a wire rack for at least 1 hour.
Step 5: Add the Marshmallow Topping
Once the pie has cooled, top it with an even layer of mini marshmallows, pressing them gently into the surface.
Turn the oven to broil and place the pie on the top rack. Broil for 30–60 seconds, watching very closely, until the marshmallows puff and turn golden brown. Remove immediately to prevent burning.
Let the pie sit for 10 minutes before slicing so the marshmallow topping sets slightly.
