Mix rice and gravy mixture in crockpot

Put chicken in and mix gravy around to fully cover the chicken

Put crockpot on low, and let cook for 5-6 hours. Mix every 2-3 hours, or use a crockpot liner to ensure rice doesn't burn on bottom. If cooking in the oven, cook for 2 hours @ 350°F

Add more rice and milk / water to increase rice content as desired. Note that a consistent rice to water mix will ensure correct rice and chicken moisture content at the end
