Butterfly chicken breast: split horizontally, stop before cutting all the way through, and unfold it like a book. Pound the chicken to an equal thickness of 1/4 and 1/2 inch using a meat mallet and season with salt and pepper
Add oil to a medium-sized, heavy-bottomed pan and heat to 340°F. Three bowls or trays should be prepared: one for panko, one for flour, and one with an egg mixture.
Combine the egg and oil by whisking them together. Take off any excess flour after coating the chicken. Then use the beaten egg to cover it. Add panko pressing it into the chicken to ensure good adhesion.
Shredded cabbage salad goes best with Chicken Katsu.Tonkatsu, Ebi Fry, Korokke, and other panko-breaded fried delicacies are frequently served in Japan over a side of finely shredded cabbage.
