01 - Season chicken thighs evenly with salt and pepper, then arrange them in a single layer at the bottom of the slow cooker.
02 - In a medium mixing bowl, whisk together honey, soy sauce, minced garlic, ketchup, olive oil, dried thyme, and red pepper flakes until well combined. Pour the sauce evenly over the seasoned chicken.
03 - Cover and cook on the low setting for 4 to 5 hours, until the chicken is fork-tender and cooked through to an internal temperature of 165°F.
04 - For a richer, thicker sauce, whisk cornstarch and water together to form a slurry. Transfer the chicken to a plate, stir the slurry into the cooking liquid, then set the slow cooker to high for 10 to 15 minutes until the sauce coats the back of a spoon. Return the chicken to the sauce and turn to coat.
05 - Plate the chicken, spoon the sauce over each portion, and finish with a sprinkle of chopped fresh parsley and sesame seeds. Serve alongside steamed rice and your favorite vegetables.
