This holiday side pairs creamy, spiced sweet potato filling with a crunchy brown sugar pecan streusel instead of marshmallows. A touch of bourbon and vanilla deepens the flavor without overpowering the dish. It bakes until the topping turns golden and the filling is warmed through, making it a fitting centerpiece for Thanksgiving or Christmas dinner.
Ingredients
- 3 pounds sweet potatoes, peeled and cubed
- 1/2 cup unsalted butter, melted
- 1/3 cup granulated sugar
- 1/3 cup packed brown sugar
- 2 large eggs
- 1/2 cup whole milk
- 2 tablespoons bourbon
- 2 teaspoons vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/2 teaspoon salt
- 1 cup all-purpose flour
- 1/2 cup packed brown sugar
- 1/2 cup unsalted butter, cold and cubed
- 1 1/4 cups pecans, chopped
- 1/4 teaspoon salt
Method
-
Place the sweet potato cubes in a 6-quart saucepan and cover with cold water by 2 inches. Bring to a boil over high heat, then reduce to a simmer and cook until fork-tender.
-
Drain the sweet potatoes well and return them to the pot. Mash until smooth, or use a potato masher for a slightly textured mash.
-
Preheat the oven to 350°F. Butter a 9x13-inch baking dish.
-
In a large bowl, whisk together the melted butter, granulated sugar, brown sugar, eggs, milk, bourbon, vanilla extract, cinnamon, nutmeg, and salt until smooth.
-
Add the mashed sweet potatoes to the bowl and stir until fully combined and smooth.
-
Spread the sweet potato mixture evenly into the prepared baking dish.
-
Make the streusel: in a medium bowl, combine the flour, brown sugar, and salt. Add the cold cubed butter and work it in with your fingers or a pastry cutter until the mixture resembles coarse crumbs.
-
Stir the chopped pecans into the streusel mixture, then scatter evenly over the sweet potato layer.
-
Bake until the streusel is golden brown and the filling is heated through, 40 to 45 minutes.
-
Let the casserole rest for 10 minutes before serving.
