Prepare the Chicken: Rinse the chicken breasts and pat them dry with paper towels to remove excess moisture. Trim any fat if desired.
Season the Chicken: Rub the chicken breasts with olive oil (if using), then season them with garlic powder, onion powder, paprika, dried thyme (or rosemary), salt, and pepper on both sides. Make sure to coat evenly.
Place Chicken in Slow Cooker: Arrange the seasoned chicken breasts in the bottom of the slow cooker. Pour chicken broth over the chicken. The liquid will help keep the chicken moist as it cooks.
Cook: Cover and cook on low for 4-6 hours, or on high for 2-3 hours. The chicken is ready when it reaches an internal temperature of 165°F (75°C) and is tender.
Shred the Chicken: Once the chicken is cooked, remove it from the slow cooker and place it on a plate. Use two forks to shred the chicken into bite-sized pieces.
Return to Slow Cooker: For extra flavor, return the shredded chicken to the slow cooker and stir it into the cooking juices. Let it sit for 10-15 minutes on warm.
Serve: Serve the shredded chicken on sandwiches, tacos, wraps, or alongside your favorite side dishes. Garnish with fresh parsley if desired. Enjoy!
