Start by seasoning the boneless, skinless chicken breasts with salt and black pepper. Sprinkle on the smoked paprika, garlic powder, onion powder, and optional cayenne pepper. Ensure the spices coat the chicken evenly for maximum flavor.
In a mixing bowl, whisk together the BBQ sauce, chicken broth, apple cider vinegar, and brown sugar. Stir until all ingredients are well mixed and the sugar has dissolved, creating a luscious sauce.
Transfer the seasoned chicken breasts into the bottom of the crockpot. Carefully pour the mixed BBQ sauce over the chicken, ensuring it is well covered for tender and flavorful results.
Cover the crockpot with its lid. Set your cooker to low and let it cook for 6-8 hours, or on high for 4 hours. The chicken is done when it has turned tender and can be shredded effortlessly with a fork.
Once the cooking time is up, remove the chicken from the crockpot using tongs or a slotted spoon. Shred it with two forks until it reaches your desired texture. Return the shredded chicken back into the crockpot, mixing it well with the barbecue sauce for a deliciously sticky consistency.
Generously spoon the pulled BBQ chicken onto soft buns. If desired, top with a generous helping of coleslaw for added crunch and flavor.
Notes
For an appealing serving idea, present your pulled chicken sandwiches on a wooden board. Serve alongside a dish of pickles and a small bowl of extra barbecue sauce for drizzling.
