1 (8oz) package of cooked spaghetti
2 tablespoons of butter OR margarine
1 cup grated Parmesan cheese, divided
1 (24oz) carton ricotta cheese
1 lb ground beef
1 jar of preferred spaghetti sauce
1 (8oz) package shredded mozzarella cheese
Preheat oven to 400 degrees F. Line a 13x9x2 inch baking pan with Reynolds Wrap.
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 1/2 cup Parmesan cheese. Brown ground beef, drain; add pasta sauce. Mix. 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.
