01 - Season chicken thighs evenly with salt and pepper. 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 the slow cooker and cook on low for 4 to 5 hours, or until the chicken is 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 thickens. Return the chicken to the sauce and turn to coat.
05 - Transfer the chicken to a serving platter, spoon the sauce over the top, and finish with chopped fresh parsley and sesame seeds. Serve immediately over steamed rice alongside your favorite vegetables.
