Ingredients

Scale
  • 3 cups cooked and mashed sweet potatoes (about 4 large sweet potatoes)
  • 1/2 cup granulated sugar
  • 1/2 cup packed light brown sugar
  • 1/2 cup (1 stick) unsalted butter, melted
  • 2 large eggs, lightly beaten
  • 1/2 cup milk
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • Pinch of salt
  • 1 cup chopped pecans
  • 1/2 cup packed light brown sugar (for topping)
  • 1/2 cup all-purpose flour
  • 1/4 cup (1/2 stick) cold unsalted butter, cut into small pieces

Instructions

  1. Preheat your oven to 350°F. Lightly grease a 9×13 inch baking dish.
  2. In a large bowl, combine the mashed sweet potatoes, 1/2 cup granulated sugar, 1/2 cup brown sugar, 1/2 cup melted butter, eggs, milk, vanilla extract, cinnamon, nutmeg, and salt. Mix until the filling is smooth and well combined.
  3. Pour the sweet potato mixture evenly into the prepared baking dish.
  4. Prepare the pecan streusel topping: In a separate medium bowl, combine the 1 cup chopped pecans, 1/2 cup brown sugar, and flour. Use your fingers or a pastry blender to cut in the cold butter until the mixture resembles coarse crumbs.
  5. Sprinkle the pecan streusel topping evenly over the sweet potato filling.
  6. Bake for 30 to 35 minutes, or until the topping is golden brown and the filling is heated through.
  7. Let the casserole cool for 10 minutes before serving.

Notes

  • You can cook the sweet potatoes by boiling, baking, or microwaving until tender before mashing them for the filling.
  • For an easy make-ahead option, prepare the entire casserole through step 4, cover it, and refrigerate for up to 24 hours. Add about 10-15 minutes to the baking time if baking directly from the refrigerator.
  • If you prefer a maple flavor, substitute 2 tablespoons of the milk with pure maple syrup in the filling mixture.
