To make sauce, cook onion in butter or margarine till tender but not brown. Stir in flour, 1 1/2 tsp. salt, and 1/8 tsp. pepper. Add milk. Cook and stir till thickened and bubbly. Cook and stir 1 to 2 minutes more. Remove from heat. Place half of the sliced potatoes in a greased 2 quart casserole. Cover with half of the sauce. Repeat layers. Bake, covered, in a 350 degree F oven 45 minutes, stirring once. Uncover, bake about 30 minutes more or till potatoes are done. Makes 4 to 6 servings.
Prepare recipe as above, except reduce salt to 1 teaspoon; stir 1/2 cup shredded American cheese into sauce till melted.
My variation is to increase flour to 1/3 cup and milk to 3 to 3 /12 cups for creamier potatoes. Also, add parsley as desired.
One of my most requested dishes to bring to a dinner.
