Pat the chicken breasts dry and season both sides with salt and pepper.
Set up a breading station with three shallow bowls: flour in the first, beaten eggs in the second, and a mixture of breadcrumbs, Pecorino Romano, and lemon zest in the third.
Dredge each chicken breast in flour, shaking off excess, then dip into the egg wash to coat completely.
Press the chicken into the breadcrumb mixture, ensuring an even and firm coating on both sides.
Heat oil in a large skillet over medium-high heat until shimmering.
Add chicken to the skillet in batches, frying for 3 to 4 minutes per side until golden brown and the internal temperature reaches 165°F (74°C).
Transfer chicken to a wire rack or paper-towel-lined plate to drain.
Garnish with fresh parsley and serve immediately with lemon wedges.
