01 - Pound beef escalopes between plastic wrap until approximately ¼ inch thick for even cooking.
02 - Arrange three shallow dishes: flour mixed with salt and pepper; beaten eggs whisked with milk; panko combined with grated Parmesan.
03 - Dredge each escalope in flour, shaking off excess. Dip into egg mixture, then press firmly into breadcrumb-Parmesan blend to coat evenly.
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 deep golden brown and crispy. Fry in batches without overcrowding pan for proper browning.
06 - Transfer cooked escalopes to paper towels to drain excess oil. Keep warm while finishing remaining batches.
07 - Plate escalopes while hot, garnished generously with chopped parsley and fresh lemon wedges on the side.
