Prepare your coating stations by setting up three bowls. Place flour in one, beaten egg in another, and mix panko breadcrumbs with seasonings in the last bowl.

Dredge each chicken breast in flour, dip it in egg, then press it into the panko mixture for coating. Repeat for all breasts.

Preheat air fryer to 400°F (200°C) for about 5 minutes. Cook coated chicken for 9 minutes, flip and cook for another 7–8 minutes until golden brown and cooked through.

Toast hamburger buns in the air fryer for 1–2 minutes at 400°F while the chicken cooks, if desired.

Assemble the burgers by placing a crispy chicken patty in each bun and add desired toppings.
