Creating Air Fryer Korean Soy Garlic Chicken Thighs can be simple by following these steps:

1. Prepare the Marinade: In a bowl, combine minced garlic, soy sauce, brown sugar, sesame oil, ground ginger, black pepper, and red pepper flakes if using. Mix well.
2. Marinate the Chicken: Place the chicken thighs in a resealable bag or bowl and pour the marinade over them. Ensure the chicken is well-coated. Seal or cover and let marinate in the refrigerator for at least 30 minutes, preferably up to 2 hours for deeper flavor.
3. Preheat the Air Fryer: Preheat your air fryer to 380°F (190°C) for about 5 minutes.
4. Remove from Marinade: Take the chicken thighs out of the marinade, letting any excess drip off. Discard the remaining marinade.
5. Arrange in Air Fryer: Place the chicken thighs skin-side down in the air fryer basket. Make sure they are not overcrowded for even cooking.
6. Cook the Chicken: Cook at 380°F (190°C) for 15 minutes. After 15 minutes, flip the chicken thighs over and cook for an additional 10 minutes or until the internal temperature reaches 165°F (75°C).
7. Let it Rest: Once cooked, remove the chicken thighs from the air fryer and let them rest for 5 minutes. This helps retain moisture.
8. Garnish and Serve: Sprinkle chopped green onions and sesame seeds over the chicken before serving for added flavor and crunch.
