01 - Place chicken breasts in a single layer at the bottom of the crockpot.
02 - Whisk together the barbecue sauce, honey, Worcestershire sauce, Dijon mustard, apple cider vinegar, smoked paprika, garlic powder, onion powder, and black pepper in a medium bowl until thoroughly combined.
03 - Pour the sauce evenly over the chicken breasts, ensuring all pieces are well coated.
04 - Cover and cook on LOW for 4 to 6 hours, or until chicken reaches an internal temperature of 165°F and is very tender.
05 - For shredded chicken, use two forks to shred the chicken directly in the crockpot, then stir to coat with sauce. Serve hot, garnished with fresh parsley or chives if desired.
