Prep the chicken: Pat the chicken dry and season lightly with salt, pepper, garlic powder, and onion powder.
Set up the dredging stations: Bowl 1: Flour, Bowl 2: Beaten eggs, Bowl 3: Crushed corn flakes.
Coat the chicken: Toss each piece in flour (shake off excess), dip in egg, then press firmly into crushed corn flakes until coated all over.
Air fry: Preheat air fryer to 380°F (190°C) for 3–4 minutes. Spray basket with oil, arrange nuggets in a single layer. Spray the tops lightly with oil for extra crispiness. Cook 10–12 minutes, flipping halfway, until golden brown and internal temp hits 165°F (74°C).
Make the Korean glaze (optional but worth it): In a small pan, heat all glaze ingredients over medium heat until it bubbles and thickens slightly (about 2–3 minutes).
Toss and serve: Coat the nuggets in glaze or drizzle over the top. Sprinkle with sesame seeds and green onions.
