Prep the chicken: If using whole chicken breasts, slice them horizontally to make thin cutlets.
Place between sheets of plastic wrap and gently pound to even thickness, about 1/4 inch. Pat dry with paper towels.
Season generously: Sprinkle both sides with salt and pepper. This helps build flavor all the way through, not just on the crust.
Set up a breading station: In one shallow dish, add flour.
In a second, whisk eggs until smooth. In a third, combine breadcrumbs, Parmesan, garlic powder, onion powder, and oregano. Taste the breadcrumb mixture and adjust salt if needed.
Dredge the cutlets: Coat each piece in flour, shaking off excess.
Dip into egg, letting the excess drip off. Press firmly into the breadcrumb-Parmesan mix, coating both sides. Set on a wire rack to rest for 5 minutes so the coating adheres.
Heat the pan: Use a large skillet and add a mix of olive oil and neutral oil to reach a shallow layer, about 1/8 inch.
Heat over medium to medium-high until shimmering. A breadcrumb dropped in should sizzle on contact.
Pan-fry in batches: Add cutlets without crowding. Cook 2–3 minutes per side until deep golden and crisp.
If desired, add a small knob of butter in the last minute for extra color and flavor.
Check doneness: Internal temperature should reach 165°F (74°C). Since cutlets are thin, they cook quickly, so watch closely.
Drain and rest: Transfer to a wire rack set over a sheet pan or onto paper towels. A rack keeps the bottom crisp.
Sprinkle with a pinch of salt while hot.
Finish and serve: Squeeze fresh lemon over the cutlets. Garnish with chopped parsley. Serve immediately with a side salad, roasted vegetables, or pasta.
