We only had these at Christmas time growing up. John would rather have mashed potatoes...
1 bag frozen hash browns- thawed
2 cans cream of chicken soup
1 1/2 c shredded cheddar cheese
1 c sour cream
1/2 onion, chopped
1/2 c melted butter
Mix soup, cheese and sour cream in a bowl; add remaining ingredients. Top with more cheese. Bake at 350 for 30 minutes or heated thoroughly.
