Dredge the chicken pieces in flour, ensuring they are well-coated.
Preheat your air fryer to 375°F (190°C).
Arrange the chicken pieces in a single layer in the air fryer basket.
Air fry the chicken for 12-14 minutes, flipping halfway through, until crispy and golden brown.
In a bowl, combine the gochujang, soy sauce, oyster sauce, and roasted sesame oil.
Add the cooked chicken to the bowl and toss to coat evenly with the sauce mixture. Serve and garnish with green onions and roasted sesame seeds.
