Preheat oven to 350ºF. Lightly spray a 9x9-inch baking dish with cooking spray.
Combine chicken, cheese, sour cream dip, and cream of chicken soup. Spread into prepared pan.
Sprinkle French fried onions over chicken mixture.
Bake uncovered 30 to 40 minutes.
Notes:
For the french onion dip, it is important to use a container for a refrigerated sour cream dip in this recipe. Look for Kraft, Barber's, Dean's, or Heluva Good Dip.
I used a rotisserie chicken in this recipe. Rotisserie chicken is a great time saver. I use it in all of my chicken casseroles.
If you can't find the sour cream dip, you can substitute sour cream and some onion soup mix.
I suggest using Unsalted Cream of Chicken Soup in this dish to control the sodium.
You can assemble the casserole ahead of time and refrigerate it overnight. You may need to add a few minutes to the cooking time if baking straight from the refrigerator.
You can assemble the casserole ahead of time and freeze the casserole unbaked for later. To bake after freezing, thaw completely and bake as directed below.
You can also freeze the baked casserole. To reheat after freezing, thaw the casserole. Cover casserole with aluminum foil. Bake at 350ºF for 30 to 45 minutes, until warm.
