Pound veal to about 1/4 inch thickness. Pat dry. Season both sides with salt and pepper.
Arrange three shallow bowls for breading: flour, beaten eggs mixed with milk, and breadcrumbs.
Dredge each cutlet in flour, shaking off excess so only a light coat remains.
Dip into the egg mixture, letting extra drip back into the bowl.
Coat with breadcrumbs, pressing gently to adhere. Rest breaded cutlets 10 minutes.
Heat oil and butter in a large skillet over medium-high until hot and foamy.
Fry cutlets in batches, 2 to 3 minutes per side, until deeply golden and crisp.
Drain on a rack. Sprinkle with parsley and a squeeze of lemon juice.
Season to taste and serve immediately while hot and crunchy.
