Mushroom Herb Veal Gratin

Preheat broiler with rack 4 inches (10 cm) from heat. Line a large rimmed baking sheet with foil; lightly butter foil.

If necessary, place veal cutlets between sheets of plastic wrap and pound to 1/4-inch (0.5 cm) thickness. Cut into 12 equal-size pieces. In a shallow dish, combine 3 tbsp (45 mL) of the cornstarch and half each of the salt and pepper. Dip cutlets into cornstarch, turning to lightly coat both sides (discard any excess). Place veal in a single layer on prepared baking sheet.

Broil for about 2 min, until lightly browned. Flip over and broil for 1 min, until just browned. Transfer veal to a 13 x 9-inch (33 x 23 cm/3 L) glass baking dish, overlapping as necessary; set aside. Position rack 6 inches (15 cm) from heat; leave broiler on.

In a large saucepan, melt butter over medium-high heat. Sauté mushrooms, onion and thyme for 7 min or until browned. In a bowl, whisk a little of the milk into remaining 1 tbsp (15 mL) cornstarch to form a paste. Whisk paste into remaining milk, then gradually stir into saucepan. Cook, stirring, for about 3 min or until bubbling and thickened. Remove from heat. Stir in remaining salt and pepper and the lemon zest and juice. Pour evenly over veal in baking dish.

In a bowl, combine Canadian Swiss or Cheddar cheese, bread crumbs and parsley. Sprinkle evenly over mushroom sauce in baking dish. Broil for about 3 min or until topping is golden.
