1 1/2 lbs. frozen hash brown potatoes
1/2 pt. half & half, or milk
1/4 lb. butter
1/2 lb. American processed cheese (we prefer Velveeta)
4 oz. sharp cheddar cheese, grated

Arrange frozen hash brown potatoes in a 9"x9" baking dish. Melt all remaining ingredients in a saucepan; pour over potatoes; stir gently to mix. Cover and refrigerate for one hour or longer. Bake uncovered in preheated 350 degree oven for 1 hour. Makes 9 to 12 servings.

Chef's Note: May be frozen after baking. 8"x8" pan will also work.
