Spray a 9”x13” baking dish with cooking spray and pour rice into a casserole dish. Cover rice with 1 cup Jack cheese and then layer on uncooked chicken pieces over the top of the cheese. Sprinkle chicken with paprika and layer with the remaining 1 cup grated cheese.
Add broth (or water) to the soup. Mix and spoon over top of the cheese.
Add the melted butter to stuffing mix and spread over the top of the casserole.
You can refrigerate overnight (or freeze it for later) or cook immediately.
