Start by placing the chicken breasts between two sheets of plastic wrap. Using a meat mallet or rolling pin, gently pound the chicken to an even thickness of about ½ inch.
In one shallow bowl, add the all-purpose flour and season with salt and pepper. In a second bowl, whisk the eggs until well combined. In the third bowl, combine the panko breadcrumbs with the Italian seasoning.
Take each chicken breast and coat it in the flour, shaking off any excess. Next, dip it into the egg mixture, allowing any excess to drip off, and finally coat it with the panko breadcrumbs, pressing gently to ensure the breadcrumbs adhere well. Repeat for all chicken breasts.
In a large skillet, add enough cooking oil to cover the bottom of the pan generously. Heat the oil over medium-high heat until it shimmers but is not smoking.
Carefully add the breaded chicken cutlets to the hot oil, cooking in batches if necessary. Fry for about 3-4 minutes on each side or until golden brown and cooked through. The internal temperature should reach 165°F (75°C).
Once cooked, transfer the chicken cutlets to a plate lined with paper towels to drain any excess oil. Serve warm with your favorite sides or sauces.
