01 - Rub the chicken all over with olive oil, salt, pepper, paprika, thyme, and rosemary, ensuring even coverage on all surfaces.
02 - Place carrots, potatoes, celery, onion, and garlic in the bottom of the crockpot, creating an even layer to support the chicken.
03 - Set the whole chicken on top of the vegetables. Add the bay leaf and pour the chicken broth around the chicken, avoiding direct pouring over the meat.
04 - Cover and cook on LOW for 6-7 hours, until chicken reaches internal temperature of 165°F and vegetables are tender.
05 - Carefully transfer chicken and vegetables to a serving platter. Remove and discard the bay leaf before serving.
06 - Pour cooking liquid into a saucepan. Mix cornstarch and cold water, then whisk into the liquid. Bring to a simmer over medium heat, stirring constantly until thickened, about 2-3 minutes.
07 - Carve the chicken and serve with vegetables alongside, drizzling with gravy if prepared.
