  • To make the cooked, cooled, and mashed sweet potatoes, peel three large or four medium sweet potatoes, cut them into 1-inch slices, and put them in a saucepan. Cover them 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 this dish 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, and cover and refrigerate it. Take the casserole out of the refrigerator about 30 minutes before baking. Spread with the topping and bake as directed.

Recipe Variations

  • 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.
  • Coconut Pecan Topping: Combine 1 cup chopped pecans, 3/4 to 1 cup flaked coconut, 1 cup brown sugar, 1/2 cup flour, and 1/4 cup melted butter. Stir until the mixture is crumbly and sprinkle it over the sweet potato filling.
