I used to think my aunts’ secret recipe was lost forever, but guess what? I finally found it, and it’s even more delicious!

Preheat oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish.
Combine rice, cream of mushroom soup, cream of celery soup, cream of chicken soup, and water in the prepared dish. Stir well.
Season chicken breasts with salt and pepper. Place on top of rice mixture.
Sprinkle onion soup mix evenly over chicken.
Cover dish tightly with aluminum foil.
Bake for approximately 1 1/2 hours, or until chicken is cooked through and rice is tender. Do not peek!
Let sit for a few minutes before serving.
