4 to 5 c. spaghetti sauce
8 oz. lasagna noodles
1 lb. Ricotta cheese
8 oz. Mozzarella cheese
1 c. grated Parmesan

In a 9 x 13 pan spread about 1 cup spaghetti sauce. Arrange a layer of uncooked lasagna. Top with some sauce, then Ricotta, Mozzarella and Parmesan cheese. Then sauce. Repeat gently pressing lasagna into cheese mixture. Pour remaining sauce over all, making sure all lasagna pieces are covered with sauce. Top with remaining Mozzarella and Parmesan cheese. Don't be concerned with empty spaces at ends. Lasagna will expand.

Bake at 350 degrees for 45 to 55 minutes until bubbly. Let stand 15 minutes before serving.
