Au Gratin Potatoes

 About 4 large potatoes, peeled,     sliced very thin

 1 or 2 onions, sliced thin

 Layer the above in a buttered dish. Sprinkle salt and fresh ground black pepper between the layers

 

 Sauce:

 4 tablespoons (1/2 stick) butter

 1 to 2 tablespoons flour

 About 2 cup milk

 3/4 to 1 cup cheese (more or less) sharp Cheddar, Velveeta, Swiss, etc., grated or shredded,

Bread crumbs, plain or mixed with parmesan cheese

 

 Melt butter, add flour to make a loose paste ( you have to judge this one...the thicker the paste, the thicker the sauce). Don't let it brown. Add milk and mix together with a whisk until it gets thick. Add some salt and pepper. Add cheese. Pour sauce between the layers. You can add more cheese between the layers too. Top with cheese and a thin layer of plain bread crumbs. Bake in a 400 degree F oven for 1 1/2 hours.
