Ingredients

Scale
  • 3 large sweet potatoes (about 2 pounds), scrubbed and sliced into ¼-inch rounds
  • 4 tablespoons unsalted butter, melted
  • ½ teaspoon salt
  • ½ teaspoon cinnamon
  • ½ cup packed light brown sugar
  • ¾ cup chopped pecans
  • ¼ cup all-purpose flour
  • 3 tablespoons unsalted butter, cold and cubed
  • ½ teaspoon vanilla extract
  • Pinch of salt

Instructions

  1. Preheat oven to 400°F (200°C).
  2. Wash and dry sweet potatoes; slice into ¼-inch thick rounds. Place in a large mixing bowl.
  3. In a small bowl, melt 4 tablespoons butter. Pour over sweet potato slices, add ½ teaspoon salt and ½ teaspoon cinnamon. Toss to coat evenly.
  4. Arrange sweet potatoes in a 9×13-inch baking dish, overlapping slightly in a single layer.
  5. In a separate bowl, combine ½ cup packed light brown sugar, ¼ cup all-purpose flour, and a pinch of salt. Add ¾ cup chopped pecans. Add 3 tablespoons cold cubed butter and ½ teaspoon vanilla extract. Use a pastry cutter or fingers to work butter into dry ingredients until mixture resembles coarse crumbs.
  6. Sprinkle streusel mixture evenly over sweet potatoes.
  7. Bake uncovered for 20-25 minutes, until sweet potatoes are fork-tender and streusel is golden brown and bubbling. If topping browns too quickly, tent with foil.
  8. Let rest for 5 minutes before serving. Serve warm.

Notes

Slice sweet potatoes evenly for even cooking. Cold butter is essential for a crumbly streusel. Watch the oven at the end to prevent burning. For make-ahead, assemble without baking, cover, and refrigerate up to 24 hours; add 10 minutes to baking time. Leftovers keep in the refrigerator for up to 4 days or freeze for up to 3 months.
