Hash Brown Casserole

6lbs frozen hash browns (I like the Southern Style)
5 cups grated cheddar cheese
2 cups sour cream

White sauce:
1/2 cup butter
3/4 cup flour
1 tsp salt
1 tsp garlic
4 cups milk

Melt butter in medium saucepan. Stir in flour, salt, garlic. Cook for 1 minute. Slowly stir in milk. Continue stirring with wire whisk until slightly thickened. Cool slightly.

Sitr together frozen potatoes and cheese. Set aside while you cook the white sauce. When white sauce is slightly cooled, stir in sour cream. Mix everything together. Put into a greased 5qt casserole. Bake uncovered at 350deg for 2 hrs or less if potatoes are tender.

Serves at least 14. :-)
