01 - Prepare three shallow bowls: place flour in the first bowl; whisk eggs and milk in the second bowl; combine breadcrumbs, Parmesan, oregano, garlic powder, salt, and pepper in the third bowl.
02 - Pat chicken breasts dry with paper towels. Dredge each breast in flour, shaking off excess. Dip into egg mixture, allowing excess to drip off, then coat thoroughly with breadcrumb mixture, pressing firmly to adhere.
03 - Pour oil into a large skillet and heat over medium-high heat until shimmering but not smoking.
04 - Add chicken cutlets in batches without overcrowding the pan. Fry for 3–4 minutes per side until golden brown and cooked through, reaching an internal temperature of 165°F. Transfer to paper towels to drain.
05 - Arrange cutlets on a serving platter and accompany with fresh lemon wedges.
