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