Below are some ideas for changing up this Casserole recipe. You can change the cheeses or the meat. If you'd like to use more or less cheese you're going to start to change the consistency of the dish. More cheese will have a creamier, richer consistency. Less cheese will result in a Casserole that is dry, and is not recommended. If you'd like to make your hash browns meatier, you can add in some extra meat, however you might want to add in a little extra cheese to coat the extra ingredients.
