01 - Set up three shallow bowls: place flour in the first bowl, whisk eggs with milk in the second bowl, and combine breadcrumbs, Parmesan, oregano, garlic powder, salt, and pepper in the third bowl.
02 - Pat chicken breasts dry with paper towels. Dredge each cutlet in flour, shaking off excess. Dip into egg mixture, allowing excess to drip off, then press firmly into breadcrumb mixture to coat evenly on both sides.
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 to 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 platter and serve immediately with lemon wedges on the side.
