Place the cooked macaroni in a slow cooker that has been coated with nonstick vegetable spray. Add the remaining ingredients except 1 cup of the cheese; mix well. Sprinkle with remaining 1 cup cheese, then cover and cook on LOW for 5 to 6 hours, or until the mixture is firm and golden around the edges. Do not remove the cover or stir until the macaroni has finished cooking.
