A hearty casserole layered with mashed potato, cheese, and caramelized onion captures all the flavor of a pan of sautéed pierogi, but is far easier to make.
Ingredients
1 cup finely chopped onion
1/4 cup butter, cubed
2 cups 4% cottage cheese, drained
1 large egg
1/4 teaspoon onion salt
2 cups mashed potatoes (with added milk and butter)
1 cup shredded cheddar cheese, divided
1/4 teaspoon salt
1/8 teaspoon pepper
9 lasagna noodles, cooked and drained
Optional: sour cream and chopped chives
Instructions
1Prep ingredients for each layer
2In a skillet, sauté onion in butter until tender. In a bowl, combine the cottage cheese, egg and onion salt. In another bowl, combine the potatoes, 2/3 cup cheddar cheese, salt and pepper.
3Build the casserole and bake
4Place three noodles in a greased 13x9-in. baking dish. Top the noodles with the cottage cheese mixture and add three more noodles. Top this layer with the potato mixture, remaining noodles and sauteed onion. Top it with the remaining 1/3 cup cheese. Cover and bake at 350°F until heated, for 25 to 30 minutes. Let the lasagna stand for 10 minutes before serving. If desired, top with chopped chives and serve with sour cream.
