Use butter to grease the bottom of a large glass baking dish. Peel potatoes and slice into 1/4 inch thick slices. Cover the bottom of the dish with a layer of potatoes. Pierce them with a fork. Place pork chops in a layer on top.

Mix soup and 1 can water in a separate bowl. Pour about 1/2 over the meat. Then continue layers until you run out of potatoes, pierced. Pour remaining soup over the top.

Bake at 400 degrees for 30 minutes to an hour, until potatoes reach desired tenderness.
