Pre heat oven at 350 degrees
Grease a 9x13 cake pan
In the cake pan, ,mix the box of rice, cans of celery and mushroom soup and one can of water (I always add the extra can of water because I like moist rice not crunchy rice)
Arrange the raw chicken on top of the rice mixture, cover and seal with foil
Bake at 350 degrees for 2 1/2 hours and "DON'T PEEK!" your house will smell amazing!
