01 - Pound the beef escalopes between two sheets of plastic wrap to an even thickness of about 1/4 inch.
02 - Arrange three shallow bowls: one with flour mixed with salt and pepper, a second with beaten eggs and milk, and a third with panko breadcrumbs blended with grated Parmesan.
03 - Dredge each escalope in the seasoned flour, shaking off excess. Dip into the egg mixture, then press firmly into the breadcrumb mixture until fully coated.
04 - In a large frying pan, heat vegetable oil and unsalted butter over medium-high heat.
05 - Working in batches, fry each escalope for 2–3 minutes per side until golden and crispy. Avoid overcrowding the pan to ensure even browning.
06 - Transfer cooked escalopes to a plate lined with paper towels and keep warm.
07 - Serve promptly, garnished with freshly chopped parsley and lemon wedges.
