First of all, preheat your oven to 450 Fº
Then, Dry the chicken breasts completely with a paper towel. One of the parts should be placed between two plastic sheets or in a sizable plastic bag and flattened to a consistent thickness of ½ inch. Repeat with the rest of the pieces. Salt and pepper the chicken breast liberally on both sides.
Place the flour in a different, small basin. In a shallow medium bowl, whisk the eggs and the olive oil together. In a small bowl, mix panko and parmesan cheese.
Chicken should be dipped in flour and any extra coating shook off. Then, coat completely with egg wash, being sure to drain any excess. Last but not least, lightly dredge in the breadcrumbs, pressing to coat evenly. With the remaining pieces, repeat the procedure.
Fry the Chicken: In a 12-inch nonstick skillet over medium-high heat, heat ½ cup of vegetable oil. Two pieces of chicken should be gently placed in the pan after the oil is shimmering. Fry for 2 to 3 minutes, or until the first side is golden brown and crispy.
Flip the chicken after lowering the heat to medium. Cook for 3 minutes, or until the food is golden brown and the internal temperature reaches 160°F (71°C). Place the chicken on a wire cooling rack positioned on top of a sheet pan after briefly draining the excess oil on a plate lined with paper towels.
Clean the pan after discarding the extra oil. Then, add ½ cup of new vegetable oil and cook the remaining 2 pieces in the same manner.
Garnish with freshly cut parsley just before serving.
