In a bowl, whisk together the brown sugar, soy sauce, minced garlic, honey, ketchup, sesame oil, and red pepper flakes (if using).
Place the chicken pieces in the bottom of your slow cooker.
Pour the sauce mixture over the chicken, making sure each piece is well-coated.
Cover and cook on low for 6-7 hours, or on high for 3-4 hours. The chicken should be tender and easily shred with a fork when done.
About 30 minutes before serving, mix the cornstarch and water in a small bowl to create a slurry. Stir this into the sauce in the slow cooker to thicken it.
Cook for an additional 30 minutes on high, or until the sauce has thickened to your liking.
Garnish with chopped green onions before serving.
Notes
Pro tip: For those with dietary restrictions, you can substitute coconut aminos for soy sauce and use a low-carb brown sugar alternative to make this dish gluten-free and lower in sugar.
