Begin by placing your boneless, skinless chicken thighs in the slow cooker. Ensure they are evenly distributed across the bottom to allow for even cooking.

Sprinkle a generous pinch of salt over the chicken thighs, followed by cayenne pepper and poultry seasoning. Use your hands to rub the seasonings into the chicken.

In a medium bowl, whisk together the BBQ sauce, peach preserves, chicken broth, and Worcestershire sauce until the mixture is smooth and well combined.

Gently pour the prepared sauce mixture over the seasoned chicken thighs in the slow cooker, making sure to evenly cover the chicken with the sauce.

Secure the lid on your slow cooker and set it to high heat for 3 hours.

Once cooked, carefully remove the chicken thighs from the slow cooker and place them on a serving platter. Drizzle some of the remaining sauce over the top.
