Place the boneless chicken breasts into the Crockpot.
Pour the BBQ sauce over the chicken in the Crockpot, ensuring the chicken is well coated.
Cover and cook on low for 6-8 hours or high for 3-4 hours, until the chicken is cooked through and tender.
Once cooked, use two forks to shred the chicken directly in the Crockpot, mixing it with the sauce.
Take the slider buns and fill each with a generous portion of the BBQ chicken.
If desired, add coleslaw, pickles, or sliced onions on top of the chicken.
Enjoy your delicious BBQ chicken sliders with your favorite sides!
