Roast Bone In Leg of Lamb Recipe

This Roast Bone In Leg of Lamb features a garlic and herb marinated leg of lamb, roasted to medium-rare, paired with sautéed yellow potatoes and red onions. The marinade includes olive oil, fresh rosemary, thyme, garlic, and white wine, infusing the meat with savory flavors during an overnight rest. The potatoes are browned in oil and roasted to finish, creating a complete and flavorful meal.

Description

The recipe begins by scoring the surface of a 7-9 pound bone-in leg of lamb and rubbing it with a mixture of olive oil, minced garlic, fresh rosemary and thyme leaves, white wine, salt, and cracked black pepper. This seasoned lamb is refrigerated under plastic wrap for 12 to 48 hours to let the flavors penetrate deeply.

For cooking, the lamb is roasted at a high temperature initially to develop a crust, then lowered to a moderate oven until the internal temperature reaches 135° to 140°F, indicating medium-rare doneness. After resting for 15 minutes, the lamb is sliced for serving.

Meanwhile, potatoes cut into chunks and sliced red onions are sautéed in olive oil over high heat until they begin to brown, then roasted in the oven to complete cooking and crispness. This accompaniment complements the rich lamb.

Notes include reheating with beef stock to keep meat moist, storage instructions for refrigeration or freezing, and advice on white wine substitution. The recipe emphasizes serving the lamb shortly after resting for best results but allows a make-ahead approach within one hour.
