Ingredients

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

Instructions

  1. Preheat your oven to 350 degrees Fahrenheit. 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, salt, nutmeg, and cinnamon. Mix until the sweet potato base is smooth and well combined.
  3. Spread the sweet potato mixture evenly into the prepared baking dish.
  4. Prepare the pecan praline topping: In a separate medium bowl, combine the remaining 1 cup brown sugar, flour, and chopped pecans. Cut in the 1/2 cup cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
  5. Sprinkle the pecan topping evenly over the sweet potato layer.
  6. Bake for 30 to 35 minutes, or until the topping is golden brown and the filling is heated through.
  7. Remove from the oven and let it cool slightly before serving.

Notes

  • For a smoother base, press the mashed sweet potatoes through a fine-mesh sieve before mixing.
  • If you prefer a marshmallow topping, skip the pecan topping ingredients and top the casserole with 2 cups of miniature marshmallows during the last 10 minutes of baking.
  • You can cook the sweet potatoes by boiling, steaming, or baking them until tender.
