Mix 2 cans of soup (cream of chicken, mushroom or celery) with 1/2 cup water.
Put 1 cup rice in 9x13 pan, cover with liquid.
Place 6 chicken breasts on top. Sprinkle with 1 package onion-mushroom dry soup.
Cover with double aluminum foil and bake at 350 for 2 hours.
I don't know why it says to use 2 layers of aluminum foil, but I always do. The only time a didn't was when I had some of that super heavy duty foil.
Notes: use two packs soup next time, more water
