Au Gratin Potatoes

I use this recipe every Christmas Eve. They are easy, just take awhile to cook

3 T butter or margarine

3 T all purpose flour

1 1/2 tsp salt

1/8 tsp pepper

2 cups milk

1 cup (4 oz) shredded cheddar cheese

5 cups thinly sliced peeled potatoes (about 6 medium)

1/2 cup chopped onion

In a large saucepan, melt butter over low heat. Stir in the flour, salt and pepper until smooth. Gradually add milk. Bring to a boil; cook and stir for 2 minutes or until thickened. Remove from the heat; sire in cheese until melted. Add potatoes and onion; stir well.

Transfer to a greased 2 qt baking dish. Cover and bake at 350 for 1 hour. Uncover; bake 30-40 minutes or until the potatoes are tender.
