01 - Pound each beef escalope between two sheets of plastic wrap until approximately ¼ inch thick for even cooking.
02 - Arrange three shallow dishes: first with flour mixed with salt and pepper; second with beaten eggs whisked with milk; third with panko breadcrumbs combined with grated Parmesan.
03 - Dredge each escalope in flour, shaking off excess. Dip into egg mixture, allowing excess to drip off. Press firmly into breadcrumb mixture to ensure complete coating.
04 - Combine vegetable oil and butter in a large frying pan over medium-high heat until shimmering.
05 - Cook escalopes for 2 to 3 minutes per side until golden brown and crispy. Fry in batches without overcrowding the pan for proper browning.
06 - Transfer cooked escalopes to paper towels to drain excess oil. Keep warm while completing remaining batches.
07 - Plate escalopes while hot, garnished with freshly chopped parsley and accompanied by lemon wedges.
