Wash and boil 5 pounds of potatoes. Cool; peel; shred. Grease a 9X13″.
Put in large bowl:
1/2 cube margarine
2 cans cream of chicken soup
2 tsp salt
1/3 cup onion (optional)
1 pint sour cream
1/2-1 pound (I always go heavy) cheese, shredded
Combine ingredients in bowl; add shredded potatoes; mix well; put in greased pan. Bake at 350 degrees for 30 minutes. I like to top with additional shredded cheese prior to baking and let it get brown and crusty on top.
