What You'll Need

  • 3 cups mashed sweet potatoes, cooled*
  • 1 1/2 cups brown sugar (packed, divided)
  • 2 large eggs, lightly beaten
  • 1 teaspoon vanilla extract
  • 1/2 cup milk
  • 3/4 cup butter, melted (divided)
  • 1/3 cup flour
  • 4 ounces chopped pecans (1 cup)

How to Make It

  1. Heat the oven to 350 F (180 C/Gas 4).
  2. Butter a 2-quart casserole or baking dish.
  3. In a large bowl, combine the mashed sweet potatoes with 1 cup of the brown sugar, the eggs, vanilla extract, milk, and 1/2 cup of melted butter. Blend thoroughly; spoon the mixture into the prepared baking dish.
  4. In another bowl combine the remaining 1/2 cup of brown sugar, the flour, the remaining 1/4 cup of melted butter, and the chopped pecans; blend thoroughly.
  1. Sprinkle the pecan topping mixture over the top of the sweet potato casserole.
  2. Bake the casserole for 35 to 40 minutes, until the filling is hot and the topping has browned.

*Peel 3 large or 4 medium sweet potatoes; cut them into 1-inch slices and put them in a saucepan. Cover with water, bring to a boil; and lower the heat to medium-low. Cover the pan and cook for about 15 minutes, or until the potatoes are very tender. Drain, mash, and let them cool slightly before using in the recipe.

To Make Ahead  Prepare the sweet potato filling the day before. Transfer to the prepared baking dish, cover, and refrigerate. You may also prepare the topping in a separate bowl; cover and refrigerate. Take the casserole out of the refrigerator about 30 minutes before baking. Spread with the topping and bake as directed.


  • Marshmallow Topping - Omit the pecan topping and bake the casserole for 30 minutes. Top with about three to four cups of mini marshmallows. Return to the oven for 10 minutes longer, or until the marshmallows are lightly browned.
  • Pecan and Marshmallow Topping - Reduce the pecan topping ingredients by about half and sprinkle all around the edge of the baking dish. Bake for 30 minutes, then fill the center in with about two to three cups of miniature marshmallows. Continue baking for 10 more minutes, or until the marshmallows are lightly browned.
