Butterfly and/or pound your chicken breasts until they are 1/2 inch thick. Sprinkle both sides of the chicken breasts with salt and pepper to your preference
Arrange three separate shallow dishes. In the first dish, place the flour. In the second, pour the whisked egg. In the third, add the panko bread crumbs.
Coat the chicken breasts in the flour, making sure to shake off any excess.
Next, dip them into the egg, ensuring a complete coat.
Finally, press them into the panko crumbs, ensuring they are well-coated on both sides.
Heat the oil in a large skillet over medium-high heat. Once hot, place the coated chicken into the oil. Fry until golden brown, which should take 3 or 4 minutes on each side.
Carefully remove the chicken from the skillet and transfer to a plate lined with paper towels to drain excess oil. Serve warm and enjoy!
