01 - Prepare three shallow bowls: place flour in the first bowl; whisk together 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 press firmly into breadcrumb mixture to coat evenly on both sides.
03 - Heat oil in a large skillet over medium-high heat until shimmering but not smoking.
04 - Add chicken cutlets in batches, being careful not to overcrowd 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 - Serve immediately with lemon wedges on the side.
