Remove the foil for the last 10 minutes of baking to allow the top to brown slightly.
Serve hot, spooning the creamy sauce over the chicken.
For added flavor, consider sprinkling some paprika or black pepper over the top of the casserole before baking. If you prefer a bit of crunch, top the casserole with crushed Ritz crackers or breadcrumbs before the last 10 minutes of baking. You can also add a layer of cooked vegetables like peas or carrots under the soup mixture for a more complete meal. For those who enjoy a bit of cheese, a handful of shredded cheddar can be sprinkled on top for a golden, bubbly finish.
