This easy sweet potato casserole with pecan streusel is a quick and delicious holiday side dish that skips boiling and mashing. Thinly sliced sweet potatoes are coated in a buttery cinnamon mixture, topped with a crunchy pecan streusel, and baked to tender perfection.

Ingredients

Scale
  • 3 medium sweet potatoes (about 2 pounds or 900g)
  • 3 tablespoons unsalted butter, melted
  • 2 tablespoons brown sugar, packed
  • 1 teaspoon ground cinnamon
  • ½ teaspoon ground nutmeg
  • ½ teaspoon salt
  • 1 teaspoon vanilla extract
  • 1 cup pecans, chopped
  • ½ cup all-purpose flour
  • ½ cup brown sugar, packed
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon salt
  • 4 tablespoons unsalted butter, cold and cubed

Instructions

  1. Preheat your oven to 375°F (190°C). Position a rack in the middle of the oven.
  2. Peel the sweet potatoes and slice them into ¼-inch thick rounds.
  3. In a medium bowl, whisk together melted butter, 2 tablespoons brown sugar, 1 teaspoon cinnamon, nutmeg, ½ teaspoon salt, and vanilla extract. Add the sweet potato slices and toss gently until every slice is coated.
  4. Arrange the coated sweet potato slices in a 9×13-inch baking dish, overlapping them slightly in even layers. Pour any remaining butter mixture over the top.
  5. In a small bowl, combine flour, ½ cup brown sugar, ½ teaspoon cinnamon, and ¼ teaspoon salt. Add cold cubed butter and use a pastry cutter or your fingers to work it into the dry ingredients until the mixture looks like coarse crumbs with some pea-sized butter pieces. Stir in chopped pecans.
  6. Sprinkle the pecan streusel evenly over the sweet potatoes. Cover the dish tightly with aluminum foil.
  7. Bake covered for 25 minutes.
  8. Remove the foil carefully and continue baking for another 15-20 minutes, until the streusel is golden brown and the sweet potatoes are fork-tender.
  9. Let the casserole rest for 5-10 minutes before serving.

Notes

Slice sweet potatoes evenly for even cooking. Don’t overwork the streusel; leave some pea-sized butter pieces for crunch. Toast pecans first for deeper flavor. Use cold butter for the streusel. Let the casserole rest before serving to allow juices to settle.
