Leg of Lamb, Roasted Potatoes and Chimichurri Sauce

Imagine a herb-crusted leg of lamb with a golden exterior and tender, juicy slices that pull apart easily—this roast leg of lamb recipe shows you how to get those results at home. We walk through seasoning, an initial sear and an oven-roast finish so the meat stays succulent while developing a flavorful crust, plus tips for resting and carving to keep every slice perfect. Built for special dinners or holiday gatherings, this oven-roasted leg of lamb pairs beautifully with pan juices or a bright herb sauce, and the precise, even heat of your Thermador oven helps deliver consistent, restaurant-quality results every time.
