Ingredients

Scale
  • 3 cups mashed sweet potatoes (canned yams work great for speed)
  • 1/2 cup granulated sugar
  • 1/2 cup packed brown sugar
  • 2 large eggs, lightly beaten
  • 1/2 cup whole milk
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter, melted, divided
  • Topping: 1 cup all-purpose flour
  • Topping: 1 cup packed brown sugar
  • Topping: 1/2 cup granulated sugar
  • Topping: 1/2 cup chopped pecans
  • Topping: 1/4 teaspoon ground cinnamon

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish.
  2. In a large bowl, combine the mashed sweet potatoes, granulated sugar, 1/2 cup brown sugar, beaten eggs, milk, vanilla extract, and salt. Mix until smooth.
  3. Stir in 1/4 cup of the melted butter until just combined. Pour this sweet potato mixture evenly into your prepared baking dish.
  4. Prepare the topping: In a separate medium bowl, whisk together the flour, 1 cup brown sugar, 1/2 cup granulated sugar, chopped pecans, and cinnamon.
  5. Cut in the remaining 1/4 cup melted butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
  6. Sprinkle the pecan topping evenly over the sweet potato layer.
  7. Bake for 25 to 30 minutes, or until the topping is golden brown and the casserole is heated through.
  8. Let the casserole cool for 10 minutes before serving. This dish pairs perfectly with your favorite meal planning efforts for Thanksgiving.

Notes

  • For an even quicker version, use canned sweet potatoes or yams, draining them well before mashing.
  • If you prefer a marshmallow topping instead of pecans, skip the streusel ingredients and top the casserole with 2 cups of mini marshmallows during the last 10 minutes of baking.
  • You can assemble this casserole completely a day ahead. Cover and refrigerate, then add 10-15 minutes to the baking time if baking straight from the fridge.
