1 (8 ounce) package spaghetti, cooked
2 tablespoons butter OR margarine
1 cup grated Parmesan cheese, divided
1 (24 ounce) carton ricotta cheese OR cottage cheese
1 pound ground beef
1 (25.75 ounce) jar Spaghetti Sauce
1 (8 ounce) package shredded mozzarella cheese
Preheat oven to 400 degrees F. Line a 13x9x2-inch baking pan with Aluminum Foil with non-stick side toward food.
Combine hot cooked spaghetti with butter; stir until butter melts and coats spaghetti. Add 1/2 cup Parmesan cheese; stir to coat. Arrange spaghetti in an even layer in foil-lined pan. Spread ricotta cheese over spaghetti. Sprinkle with 1/4 cup Parmesan cheese. Brown ground beef, drain; add pasta sauce and heat until bubbly. Spoon over cheeses. Top with mozzarella cheese and remaining Parmesan cheese.
Cover with non-stick foil. Bake 30 minutes. Remove foil cover and continue baking 15 minutes or until cheese is lightly browned. Let stand 10 minutes before serving.
Tip: Here's the easy way to line a pan - turn the pan upside down and press Aluminum Foil (non-stick side down) around it. Remove the foil. Flip the pan upright and drop the foil inside. Crimp the edges and you're ready to cook!
