You can add cheese or not. Mom-Mom didn't and they were great. I suggest heating the milk in the microwave to get things cooking faster. Mom-Mom didn't use hers for cooking - it was just an expensive bread box to her.
This dish can be made in a large baking pan or in a deep casserole dish. The advantage of the large baking pan is the amount of surface area that gets crispy on top. The downside is the milk is likely to spill over the top and require a sheet pan underneath to catch the drips.
Slice potatoes very thin. Layer in deep casserole dish or large glass baking dish as follows:
Repeat 2 more times, ending with cheese on top. Use enough potatoes so that dish is full nearly to the top.
Heat milk in microwave (this isn't mandatory, but it gets things cooking a bit faster). Pour over potatoes. Bake uncovered in preheated 325° oven for 1-3/4 hours total, adding more milk if needed to keep it from drying out.
This batch was cooked in large glass baking dish. Notice the sheet pan underneath to catch any drippings - that is one full dish!
