Make this simple sweet potato casserole for your next holiday gathering or weeknight dinner. It features a creamy base and a buttery brown sugar pecan streusel topping.

Ingredients

Scale
  • 2 (15 ounce) cans sweet potatoes, drained and mashed (or about 3 cups fresh mashed sweet potatoes)
  • 1/2 cup granulated sugar
  • 1/2 cup packed light brown sugar
  • 1/2 cup (1 stick) unsalted butter, melted, plus 2 tablespoons for topping
  • 2 large eggs, lightly beaten
  • 1/2 cup milk
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt
  • 1/4 teaspoon ground cinnamon
  • 1 cup all-purpose flour
  • 1 cup packed light brown sugar (for topping)
  • 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, and cinnamon. 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 topping: In a separate medium bowl, whisk together the flour, 1 cup brown sugar, and chopped pecans. Cut in the remaining 2 tablespoons of melted butter using a fork or pastry blender until the mixture resembles coarse crumbs.
  5. Sprinkle the pecan topping evenly over the sweet potato mixture.
  6. Bake for 25 to 30 minutes, or until the topping is golden brown and the casserole is heated through.
  7. Let the casserole cool for 5 minutes before serving.

Notes

  • To make this a marshmallow topping casserole, omit the flour, brown sugar, and pecans for the topping. Instead, sprinkle 2 cups of mini marshmallows over the sweet potato filling during the last 5 minutes of baking until they are puffed and golden.
  • You can prepare the sweet potato filling one day ahead. Cover and refrigerate. Add the topping just before baking.
  • For an extra rich flavor, substitute evaporated milk for regular milk.
