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