01 - Place chicken breasts between two sheets of plastic wrap. Gently pound to an even 1/2-inch thickness using a meat mallet or rolling pin. Season both sides with salt and pepper.
02 - Set up three shallow bowls: one with flour; one with whisked eggs and milk; and one with panko, Parmesan, chopped basil, garlic powder, and paprika mixed together.
03 - Dredge each chicken breast first in flour, shaking off excess, then dip into egg mixture, and finally coat thoroughly in Parmesan-basil breadcrumb mixture, pressing gently to adhere.
04 - Heat oil in large skillet over medium heat. Add chicken cutlets in single layer, cooking in batches if needed. Fry for 3-4 minutes per side until golden brown and internal temperature reaches 165°F.
05 - Drain cutlets briefly on paper towel-lined plate. Serve immediately garnished with extra Parmesan, fresh basil leaves, and lemon wedges if desired.
