  • 2 cups onions, chopped
  • 1½ cups reduced-fat (2%) cottage cheese
  • ⅔ cup buttermilk
  • 3½ pounds russet potato (~4 large baking potatoes)
  • 6 tablespoons Parmesan Cheese, shredded
  • Salt and fresh ground pepper, to taste


  1. Preheat oven to 450 degrees. Cover a baking pan with foil. Line the inside of a 9-inch springform pan with foil too. Spray the foil-lined pan with cooking spray.
  2. Place onions on a microwave safe plate and cook for about 4 minutes in the microwave until soft.
  3. In a food processor or blender, add cooked onions, cottage cheese, buttermilk and process until smooth. Pour enough of mixture to coat the bottom of the spring-form pan.
  4. Peel all potatoes. Slice each very thin by hand or use a mandolin. Arrange 2 layers of slices on the pan. Start at the edge and work in, overlapping slightly. Press down on potatoes then spread with about ⅓ of cheese mixture. Season with salt and pepper and 2 tablespoons of Parmesan cheese. Layer remaining potatoes and cheese 2 more times, ending with cheese mixture. Season with a little salt and pepper and top with remaining Parmesan cheese (It made be made to this point, covered and refrigerated up to 1 day ahead).
  5. Cover pan with foil and place on foil-lined pan because it tends to leak while cooking. Bake until potatoes are tender, about 1¼ hours. Remove foil cover and continue baking until cheese is golden brown, about 30 minutes.
  6. Remove from oven and let rest for at least 30 minutes before removing from pan. Un-mold and cut into 10 slices.
  7. Makes 10 servings (each serving, 1 slice)

    Some of the quantities in this recipe show errors in the typing, i.e., "...spread with about ? of cheese mixture." and "Bake until potatoes are tender, about ? hours...."

    Makes it kinda hard to accurately measure this recipe.
