2 cups macaroni - cook and drain
cheddar cheese ( old/sharp is best) coarsely grated.
1/4 cup butter
1/4 cup flour
2 cups milk
salt and pepper to taste
I make my white sauce in the microwave but it can also be made on the stove. The method is the same.Melt butter in 8 cup microwavable bowl. Stir in flour with a wire whisk until smooth. Very gradually add milk, stirring smooth with each addition. Microwave for 1 minute at a time, stirring well each time until sauce bubbles. Add salt and pepper to taste.
In buttered casserole dish, place a layer of cooked macaroni.
Pour white sauce over to cover.
Sprinkle with grated cheese.
Repeat layers ending with cheese.Bake at 350 degrees for about 30 minutes or until it bubbles at the edges.
