01 - Place chicken breasts between plastic wrap sheets. Pound to even 1/2-inch thickness with meat mallet. Season both sides with salt and pepper.
02 - Prepare three shallow bowls: flour in first, whisked eggs with milk in second, panko mixed with Parmesan, basil, garlic powder, and paprika in third.
03 - Dredge each chicken breast in flour, dip into egg mixture, then coat thoroughly with Parmesan-basil breadcrumb mixture.
04 - Heat oil in large skillet over medium heat. Add chicken in single layer, cooking batches if needed. Fry 3-4 minutes per side until golden and internal temperature reaches 165°F.
05 - Drain cutlets briefly on paper towel-lined plate. Serve immediately with extra Parmesan, fresh basil, and lemon wedges if desired.
