Creating Slow Cooker Honey Chicken is straightforward when you follow these simple steps:

1. Prepare the Chicken: Place the boneless, skinless chicken thighs into the slow cooker.
2. Mix the Sauce: In a medium bowl, combine the honey, soy sauce, rice vinegar, minced garlic, minced ginger, sesame oil, black pepper, and red pepper flakes (if using).
3. Pour the Sauce: Pour the honey mixture over the chicken, ensuring it is well-coated.
4. Cover and Cook: Cover the slow cooker and cook on low for 6 hours or on high for 3 hours. The chicken should be tender and fully cooked.
5. Shred the Chicken: Once cooked, remove the chicken from the slow cooker and shred it using two forks.
6. Thicken the Sauce (Optional): If you prefer a thicker sauce, pour the remaining liquid into a saucepan and simmer on medium heat for 5-10 minutes until it reduces.
7. Return the Chicken: Return the shredded chicken to the slow cooker and stir to combine with the sauce.
8. Serve: Garnish with sliced green onions and sesame seeds before serving.
