Cover and cook on high for 5–6 hours (or best setting for your slow cooker) until potatoes are tender.
Top with remaining cheese just before serving.
Notes
Cheddar cheese: Sharp cheddar gives the boldest flavor, but you can mix in Monterey Jack for a creamier melt.Ham: Great for using up leftover holiday ham. Deli ham or pre-cubed ham also work.Soup substitute: Cream of mushroom soup is the classic casserole binder. Swap with cream of chicken if you prefer.Slow cooker setting: If your slow cooker runs cooler, the casserole may take up to 6 hours to finish cooking.
