My family loves this and I make it on regular rotation, it's so easy to make just mix everything in one large bowl then bake, you may prepare the complete casserole and refrigerate until ready to bake, which makes this a perfect potluck dish! --- I have even made this using frozen french fries that I cut up into small pieces when I had no hash browns on hand and can also be made using cooked cubed potatoes --- cream of chicken soup may be used in place of mushroom soup, you may even throw in some chopped cooked ham or chicken also, I most always increase this by using two cans of soup, 1-1/2 cups sour cream and using half a 5-pound bag of hash browns --- you will love this! :)
