Begin by placing the chicken thighs in the bottom of your slow cooker.
In a separate bowl, mix together BBQ sauce, chicken broth, apple cider vinegar, brown sugar, garlic powder, onion powder, smoked paprika, salt, and pepper.
Pour the sauce mixture over the chicken thighs, ensuring they are well coated.
Cover the slow cooker and set it on low heat for 6-7 hours or high heat for 3-4 hours until the chicken is tender and easily shreds.
Once cooked, remove the chicken from the slow cooker and shred it using two forks.
Return the shredded chicken to the slow cooker and stir it into the remaining BBQ sauce for additional flavor.
Toast the hamburger buns lightly in the oven or on a skillet, for a crispy texture.
Assemble the sandwiches by placing a generous portion of the pulled chicken on each bun.
If desired, top with coleslaw and pickles for an extra crunch and flavor.
Notes
Optional toppings can enhance the flavor and texture.
