This crockpot recipe is made with ham, potatoes, onion, cheddar cheese, and condensed soup. It's a very easy preparation. Just slice the potatoes and onions and layer everything in the slow cooker. Mix the soups and milk together and pour over the casserole. You can make the casserole with sharp cheddar, but mild cheddar or cheddar jack cheese will work as well. You can also use a 1-pound package of diced ham instead of slices or reduce the amount of ham and serve the potatoes as a side dish. Serve the potatoes with a tossed salad and biscuits or crusty bread.
