Prepare the Slow Cooker: Place the thawed chicken breasts inside the slow cooker and set it to low heat to begin the cooking process.
Mix the BBQ Sauce: In a separate bowl, thoroughly combine the barbecue sauce, light brown sugar, apple cider vinegar, olive oil, garlic powder, onion powder, smoked paprika, chipotle chili powder, and ground white pepper until well blended.
Coat the Chicken: Pour the prepared BBQ sauce mixture evenly over the chicken breasts in the slow cooker, ensuring all pieces are fully coated with the sauce.
Slow Cook the Chicken: Cover the slow cooker with its lid and cook the chicken for 6 to 7 hours on low heat or alternatively 3 to 4 hours on high heat, until the chicken is tender and easily shredded.
Shred the Chicken: Once cooked, shred the chicken directly in the slow cooker using two forks and mix it thoroughly with the remaining sauce to maximize flavor absorption.
Serve Your Pulled BBQ Chicken: Serve the pulled BBQ chicken hot on toasted, buttered buns for sandwiches, or incorporate it into wraps, salads, or tacos for a variety of delicious meals.
Notes
Use a slow cooker liner for easy cleanup and adjust the sweetness level by varying the amount of brown sugar or barbecue sauce.
