Tips

- Make ahead: To make ahead, assemble the casserole, cover, and refrigerate for up to 24 hours before baking. Remove from the fridge and let sit at room temperature while you preheat the oven.
Serving suggestions
Serve with a fresh green salad, fruit salad, or steamed green vegetables, like green beans, broccoli, or asparagus, to help round out the meal. You can also serve it with rolls or garlic bread to help sop up the sauce.

Haven't made it yet! However, it's the closest to the recipe my Sister used to make, that is my all time favorite! I've been searching for years to find it! I don't remember her using sour cream but Kraft Old English Cheese that comes in a small clear glass jar, with a metal lid & sealed with a hard plastic tamperproof seal. In addition, it had a very small amount of Worstershire Sauce! It is & always will be my favorite chicken dish!
