                Cut chicken breasts into uniform 2-3 cm pieces to ensure even cooking and tender texture.

                In the crockpot, whisk together chicken broth, sour cream or Greek yogurt, Dijon mustard, dried thyme, garlic powder, onion powder, salt, and pepper until smooth.

                Stir in the rinsed rice, then add the chicken pieces. Mix gently to evenly distribute ingredients and prevent clumping.

                Place broccoli florets on top of the mixture without stirring to allow gentle steam cooking during simmering.

                Cover and cook on low heat for three to four hours or on high for two to three hours, until chicken is cooked through, rice is tender, and liquid is absorbed. Avoid overcooking to maintain rice texture.

                Stir half of the grated cheddar into the hot mixture until melted. Sprinkle remaining cheese over the surface, cover, and let rest for fifteen minutes to enhance creaminess.
