Ingredients
- 1 3/4 pounds sweet potatoes (3 to 4 large), peeled and cubed
- 4 tablespoons (1/2 stick) unsalted butter, cubed, plus more for the baking dish
- Kosher salt
- 1/2 cup heavy cream
- 1/4 cup packed brown sugar
- 1 teaspoon pure vanilla extract
- 2 large eggs
- One 14- to 16-ounce box refrigerated rolled pie crusts (2 crusts)
- 3 cups mini marshmallows
Instructions
- Preheat the oven to 350 degrees F.
- Combine the sweet potatoes, butter and 1 teaspoon salt in a 2.5-quart broiler-safe baking dish and cover tightly with foil. Bake, tossing the sweet potatoes halfway through and re-covering the dish with the foil, until the sweet potatoes are tender, about 50 minutes.
- Transfer the sweet potato mixture to a large bowl, including any remaining butter from the dish. Mash with a whisk, then whisk in the cream, brown sugar, vanilla, eggs and 1/2 teaspoon salt to combine.
- Rinse and dry the baking dish, then butter it lightly. Stack the pie crusts on top of each other and roll them out on a clean surface until they are large enough to cover the bottom of the baking dish and come 2 inches up the sides; crimp the edges. Pour in the filling. Bake until the filling is set and the crust is golden, about 1 hour.
- Increase the oven to broil. Top the pie with the marshmallows and broil until golden, 1 to 2 minutes.
- To make ahead: Bake the pie and let it cool to room temperature (don’t add the marshmallows). Cover and refrigerate up to 4 days. To serve, bring the pie to room temperature and warm in a 350-degree F oven until heated through, about 15 minutes. Add the marshmallows and broil as directed above.
