Ingredients

Scale
  • 2 pounds sweet potatoes, peeled and cooked
  • 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 salt
  • For the Topping:
  • 1 cup packed light brown sugar
  • 1/3 cup all-purpose flour
  • 1/3 cup (about 5 tablespoons) cold unsalted butter, cut into pieces
  • 1 cup chopped pecans

Instructions

  1. Preheat your oven to 350 degrees F. Lightly grease a 9×13 inch baking dish.
  2. Place the cooked sweet potatoes in a large bowl. Mash them until mostly smooth.
  3. Add the granulated sugar, brown sugar, melted butter, eggs, milk, vanilla extract, and salt to the mashed sweet potatoes. Mix until the filling is well combined and creamy.
  4. Spread the sweet potato mixture evenly into the prepared baking dish.
  5. Prepare the topping: In a separate medium bowl, combine the brown sugar and flour for the topping. Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
  6. Stir in the chopped pecans until they are evenly distributed throughout the crumb mixture.
  7. Sprinkle the pecan topping evenly over the sweet potato filling.
  8. Bake for 25 to 30 minutes, or until the topping is golden brown and the filling is heated through.
  9. Let the casserole cool for 10 minutes before serving.

Notes

  • You can boil or bake your sweet potatoes until tender before mashing them for the base.
  • If you prefer a marshmallow topping, skip the pecan topping ingredients and top the casserole with 2 cups of miniature marshmallows during the last 5 minutes of baking.
  • This dish is excellent for making ahead; cover and refrigerate for up to two days before baking. Add 10 minutes to the baking time if baking straight from the refrigerator.
