6-8 med. potatoes
3 tbsp. butter
3 tbsp. all-purpose flour
1 tsp. salt
1/2 tsp. pepper
2 1/2 c. milk
1 sm. onion, chopped
1 tbsp. butter
1-1 1/2 lb. cubed ham

Wash and peel (optional) potatoes and cut into enough thin slices to measure about 4 cups. Heat 3 tablespoons butter/butter in saucepan over low heat until melted; stir in flour, salt and pepper. Cover over low heat, stirring constantly, until mixture is smooth and bubbly; remove from heat; stir in milk. Heat to boiling again, stirring constantly; boil and stir about 1 minute.

Arrange potatoes in greased 2 quart casserole in layers, topping each layer with desired amount of onion, white sauce and cubed ham. Dot top layer with 1 tablespoon butter. Cover and bake in 325 degree oven for 40 minutes, or in 350 degree oven for 30 minutes. Uncover and bake until potatoes are tender, 60-70 minutes longer. Let stand 5-10 minutes before serving.
