Oven Roasted Leg of Lamb Recipe [+ Video] - Savory Nothings (2024)

FAQs

Which cooking method is ideal for a leg of lamb? ›

Whether boneless or bone-in, the perfect leg of lamb should be either oven-roasted until blushing pink on the inside (with an internal temp around 130°F) or roasted long and slow for several hours until the meat is very tender and falls apart to internal temp around 175°F (I often use the slow cooker for that).

All the lamb needs is a sprinkle of salt and pepper, drizzle of olive oil. Add beef broth/stock and water into the pan (keeps everything all nice and moist + makes pan juices for gravy), cover then slow roast for 5 hours until tender and fall apart.

For the perfect roast lamb, we recommend seasoning the surface of the meat, and then searing it, especially fat side down in a pan before roasting. Why bother with searing? Contrary to some stories, searing is less about locking in moisture, and all about improving the flavour!

And when you have a gorgeous cut, like a rack of lamb, you can cook it the good ol' Gordon Ramsay way—which is to say, lightly pan-sear it first, then baste it with an herby, garlicky butter, and finally finish it off in the oven until it's still pink and juicy in the middle. It comes out perfectly every time.

Heat the oven to 220C/200C fan/gas 7.

The leg and rack of lamb are perfect for herb-crusting and oven-roasting; since the shank and shoulder are a bit tougher, they fare well in stews or braises—the long cook time allows them to significantly break down and become fork-tender.

Roast uncovered for 45 minutes. Slow-roast 12 hours: Turn oven down to 100°C/210°F (both fan and standard, Note 5). Cover lamb with baking paper, then a double layer of foil and seal very tightly to avoid water evaporation. Roast for 12 hours (I always do overnight!).

Temperature is by far the most critical aspect of cooking lamb chops. Undercooking even tender lamb chops can render them unpleasantly chewy, while overcooking will lead to tough, dried-out meat. Rib chops should be cooked to about 130°F, while loin chops are better at 135°F or even 140°F.

Slow cooking in liquid transforms tougher cuts of lamb into fork-tender meat. Neck, shoulder and belly, either diced or as whole joints, are the best cuts for slow cooking and need to be cooked for at least 2 hrs at 150°C to soften the meat.

Before roasting lamb, remove it from the refrigerator and allow it to sit at room temperature for at least 30 minutes. A piece of meat at room temperature will roast more evenly. Use a roasting rack to ensure even browning and heat circulation around the meat.

General Tips on How to Cook Lamb

Fattier cuts of lamb should be roasted long and slow at a low temperature, while leaner cuts of meat should be cooked at a high temperature for the first several minutes and then at a lower temperature the rest of the time.

It's not really necessary to sear your roast before cooking, but caramelizing the surface gives the cut an incredible depth of flavor, enhanced with the complex layers of nutty caramel and coffee-like bitterness that meat-lovers find delicious.

Fresh rosemary, fresh garlic, lemon zest, black pepper, and salt are simple but amazing flavors that pair amazingly with the lamb! Each of these ingredients adds its unique warmth and depth to enhance the flavor of the dish.

When meat is sliced with the grain, it often results in tougher, chewier pieces. Follow this tip: The grain of the meat refers to the direction in which the muscle fibers run. Always slice lamb against the grain, cutting across the muscle fibers rather than with them.

Place the lamb, fat side up, on a rack set in a roasting pan; spread garlic paste all over lamb. Roast in oven until a meat thermometer inserted into the thickest part of the meat registers 135 degrees, for medium rare, about 2 hours.

A boneless leg is easier to carve, while bone-in can be a bit more difficult to slice. If you're looking for a more intense lamb flavor, bone-in is the way to go.

Various cuts and cooking methods: Lamb's legs offer a range of cuts, including bone-in and boneless options. Popular cooking methods for lamb leg include roasting, grilling, and braising.

A quality leave-in thermometer like the​ ChefAlarm​®​ tracking your internal temperatures while you roast, of course! Lamb is often served on the rare side, seldom passing medium rare, ​130–35°F​(54–57°C).

Lamb loin roast is best prepared using dry heat cooking methods such as roasting, grilling, or broiling. Cook lamb loin with care, as it can dry out easily if overcooked. Other cooking methods for lamb loin roast include brushing the loin with oil and sprinkling it with salt and pepper before grilling or broiling.
