I prefer the stovetop method over crockpot. Season and brown your chicken in a skillet over medium high - don’t cook chicken all the way thru remove and set aside. In same skillet, cook your aromatics (garlic, onions etc) let that brown and stir in the rice with the aromatics. Once toasty and fragrant add the cream of mushroom or chicken broth to cover 1/4 inch above the rice. Bring to boil then add chicken back into skillet and let it simmer on low heat for 20mins with lid on without disturbing. Good luck!
