Pour the cream of chicken soup into the bottom of the slow cooker.
Add the chicken breasts. Cover and cook on HIGH for 4 hours or LOW for 6 hours.
About 30 minutes before the chicken is finished, prepare the yellow rice on the stovetop according to the package instructions.
Once the chicken is finished cooking, chop or shred it to your preferred texture.
Add the cooked yellow rice to the slow cooker and stir it together with the chicken, cream of chicken soup, and cooking juices.
Allow the dish to cool slightly before serving.
