Easy Creamy Sour Cream Chicken Casserole

"This is one of the first recipes I really "mastered" when I was learning how to cook. My husband got to enjoy this recipe at least twice a month because it was one of the few dishes I knew how to make. Now, that I'm a much better cook, we still have this delicious dinner on our menu at least monthly. It is so easy to put together and very good. If you like your casserole's creamy, then this is one you've gotta try! I hope you enjoy it as much as we do!..."
