Dredge one piece of chicken in the flour mixture, shake to remove excess. Next, dip it in the egg mixture, making sure there are no dry spots, shake gently to remove excess. Finally, dip chicken into the seasoned panko mixture, gently pressing each side into the panko to fully coat. Place each coated piece of chicken on a large plate and repeat with remaining chicken.
Save a tablespoon of the panko dredge to use for checking that the oil is at the right temp for cooking the chicken.
