This comforting and hearty recipe for crockpot chicken and rice is a family favorite. Start by processing onions, garlic, and carrots in a food processor until finely chopped. Then, add the vegetables to a crockpot along with chicken breasts, rice, chicken broth, and seasonings. Cook on low for 6-8 hours, or until the chicken is cooked through and the rice is tender. Serve hot with a side of steamed vegetables.
