Everyday mashed potatoes become appealingly elegant in Kathy Kittell's extra-cheesy souffle. "This casserole bakes up fluffy and golden-and makes a perfect company side dish," she confides from her Lenexa, Kansas kitchen.

Ingredients

  • 4 cups mashed potatoes (without added milk and butter)
  • 1 cup fat-free milk
  • 1 cup shredded reduced-fat cheddar cheese
  • 2/3 cup shredded reduced-fat Swiss cheese
  • 1/3 cup shredded Parmesan cheese
  • 1/3 cup chopped green onions
  • 1 small onion, chopped
  • 1-1/4 teaspoons salt
  • 1/4 teaspoon pepper
  • 4 large eggs, separated

Directions

  1. In a large bowl, combine the potatoes, milk, cheeses, onions, salt and pepper. Beat egg yolks; stir into potato mixture. In a small bowl, beat egg whites until stiff peaks form; gently fold into potato mixture.
  2. Transfer to a 2-qt. souffle dish coated with cooking spray. Bake, uncovered, at 375° for 40-45 minutes or until golden. Serve immediately.
