01 - Season the chicken thighs evenly with salt and pepper, then place them in a single layer at the bottom of the slow cooker.
02 - In a medium mixing bowl, whisk together the honey, soy sauce, minced garlic, ketchup, olive oil, dried thyme, and crushed red pepper flakes until well combined.
03 - Pour the sauce mixture evenly over the seasoned chicken thighs in the slow cooker. Cover with the lid and cook on the low setting for 4 to 5 hours, or until the chicken is tender and reaches an internal temperature of 165°F.
04 - If a thicker sauce is desired, whisk the cornstarch and water together in a small bowl to form a slurry. Carefully remove the chicken from the slow cooker and stir the slurry into the remaining sauce. Set the slow cooker to high and cook for 10 to 15 minutes, stirring occasionally, until the sauce has thickened. Return the chicken to the sauce and coat evenly.
05 - Transfer the chicken to a serving platter, spoon the sauce over the top, and finish with a sprinkle of chopped fresh parsley and sesame seeds. Serve immediately with steamed rice and vegetables.
