Preheat oven to 350°. Butter a casserole dish (I use a round 1½ quart that’s about 5-6” deep). Layer with thinly sliced potato, salt, pepper, flour, dots of butter, thinly sliced onion, thinly sliced ham, dollops of goat cheese. Repeat until 1½” below top. Pour milk or a combination of milk and half and half over until mixture is covered. Dot with butter. Bake for about an hour until potatoes are soft. A wonderful one dish meal.
