Sweet Potatoes

  • 7 pounds sweet potatoes (6-8 medium)


  • 8 tablespoons butter, softened and cut into small pieces
  • 1/2 cup all-purpose flour
  • 1/2 cup packed brown sugar
  • 1/4 teaspoon kosher salt
  • 1 cup pecans


  • 6 tablespoons butter, melted
  • 2 teaspoons kosher salt
  • 1/2 teaspoon ground nutmeg
  • 1/2 teaspoon ground black pepper
  • 1 tablespoon vanilla
  • 4 teaspoons lemon juice
  • 1/4 cup packed brown sugar
  • 4 large eggs
  • 1 cup half-and-half


Roasting Sweet Potatoes:

  1. Adjust the oven rack to the middle position and heat oven to 400°F.
  2. Poke sweet potatoes several times with a knife and space evenly on a rimmed baking sheet.
  3. Bake potatoes, turning them once, until they are very tender and can be squeezed easily with tongs, about 1 to 1 ½ hours.
  4. Remove the potatoes from the oven and cut in half lengthwise to let steam escape; cool at least 10 minutes. Reduce oven temperature to 375°F.

 Sweet Potato Filling:

  1. Butter a 13x9-inch baking dish.
  2. After the sweet potatoes are roasted and have cooled slightly, use a spoon to scoop the flesh into a large bowl.
  3. Add the melted butter, kosher salt, nutmeg, pepper, vanilla, lemon juice, brown sugar and eggs.
  4. Beat with a hand mixer until ingredients are smooth. You could also use a stand mixer with the paddle attachment to beat ingredients together, or a potato masher to combine ingredients. (I like to have a little texture to my casserole, so I leave some potatoes a little chunky.)
  5. Next pour in half-and-half and mix until blended.
  6. Pour the sweet potato mixture into the prepared baking dish and spread into an even layer with a spatula.

Pecan Streusel:

  1. Pulse flour, brown sugar and kosher salt in a food processor until blended.
  2. Sprinkle butter pieces over the flour mixture and pulse until coarse crumbs form.
  3. Sprinkle nuts over the flour mixture and pulse until combined, but some large pecan pieces remain.

 To Assemble & Bake Casserole:

  1. Sprinkle the pecan streusel over the sweet potato mixture.
  2. Bake for 40-45 minutes, or until the topping gets crispy.
  3. Cool 10 minutes before serving.


To make ahead, assemble casserole and wrap tightly with plastic wrap and refrigerate for up to 2 days. Bake as directed, increasing the cooking time to about 50-6o minutes if baking dish directly from the refrigerator.
