01 - Place chicken breasts between two sheets of plastic wrap and gently pound with a meat mallet to an even 1/2-inch thickness. Season both sides evenly with lemon juice, sea salt, and freshly ground black pepper.
02 - Arrange three shallow bowls: fill the first with all-purpose flour, the second with eggs whisked together with water, and the third with a blend of grated Romano cheese, Italian breadcrumbs, and lemon zest.
03 - Dredge each seasoned chicken breast in the flour, shaking off any excess. Dip into the egg wash, then press firmly into the Romano-breadcrumb mixture, ensuring an even, adherent coating on all sides.
04 - Heat olive oil and 1 tablespoon of butter in a large skillet over medium heat. Cook the breaded chicken in batches for 4 to 5 minutes per side until deeply golden and cooked through to an internal temperature of 165°F. Transfer to a warm plate and tent loosely with foil.
05 - Add the remaining tablespoon of butter and minced garlic to the same skillet. Sauté briefly until fragrant, about 30 seconds. Pour in the chicken broth and lemon juice, scraping up any browned bits from the bottom of the pan. Bring to a gentle simmer and cook for 2 to 3 minutes until the sauce reduces slightly.
06 - Return the chicken cutlets to the skillet and spoon the pan sauce generously over each piece. Sprinkle with freshly chopped parsley. Serve immediately alongside pasta, a green salad, or crusty bread.
