01 - Arrange three shallow bowls: place flour in the first; whisk eggs and milk in the second; combine breadcrumbs, Parmesan, oregano, garlic powder, salt, and pepper in the third.
02 - Pat chicken breasts thoroughly dry. Dredge each cutlet in flour, shaking off excess. Dip into egg mixture, allowing excess to drip off. Press firmly into breadcrumb mixture to coat evenly on all sides.
03 - Pour oil into a large skillet and heat over medium-high heat until shimmering but not smoking.
04 - Add breaded cutlets in batches without overcrowding. Fry 3–4 minutes per side until deep golden brown and crispy. Internal temperature should reach 165°F. Transfer to paper towels to drain.
05 - Arrange cutlets on a platter and serve hot with fresh lemon wedges for squeezing over the top.
