01 - Pound beef escalopes between plastic wrap until approximately ¼ inch thick for even cooking.
02 - Arrange three shallow dishes: flour seasoned with salt and pepper; eggs whisked with milk; panko mixed with grated Parmesan.
03 - Dredge each escalope in flour, shaking off excess. Dip into egg mixture, then coat thoroughly with breadcrumb-Parmesan blend, pressing gently to adhere.
04 - Combine vegetable oil and butter in large frying pan over medium-high heat until shimmering.
05 - Cook escalopes 2-3 minutes per side until golden brown and crispy. Fry in batches without crowding the pan for optimal results.
06 - Transfer cooked escalopes to paper towels to drain excess oil. Keep warm while completing remaining batches.
07 - Plate hot escalopes garnished with fresh chopped parsley and lemon wedges on the side.
