Pineapple, sugar and marshmallows lend a super sweetness to sweet potatoes. I've been making the casserole for years, both for special occasions and casual dinners. —Ruth Leach, Shreveport, Louisiana

  • 6 medium sweet potatoes
  • 1/2 cup butter, cubed
  • 3/4 cup sugar
  • 1 can (20 ounces) crushed pineapple, drained
  • 2 large eggs, beaten
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground nutmeg
  • 1/2 teaspoon salt
  • 15 large marshmallows


  1. Place sweet potatoes in a large kettle and cover with water; bring to a boil. Boil gently until potatoes can easily be pierced with the tip of a sharp knife, 30-45 minutes. Drain; cool slightly.
  2. Preheat oven to 350°. Peel potatoes and place in a large bowl with butter and sugar; mash. Add pineapple, eggs, vanilla, nutmeg and salt; stir to combine.
  3. Spoon into a greased 2-qt. baking dish. Top with marshmallows. Bake, uncovered, until a knife inserted in the center comes out clean, 40-45 minutes.
