Instructions
Preheat oven to 325 ° F.
Grease a 2.5 liter, or larger, round casserole dish with 1 tablespoon of the butter. Place a layer of potatoes on the bottom of the dish. Top with a thin layer of onion slices, a little shredded cheese, then season with a pinch of salt and some pepper. Continue in layers like this, gently pressing down as the layers build up, until all ingredients are used, ending with potato slices. Pour the milk over the top, and dot the remaining butter over the top.
Bake for about 1 ½ hours, until the potato feels tender when pierced with a knife. If the dish starts to brown too much, cover it with foil about ½ to 2/3 of the way through the cooking time.
