Boneless Leg of Lamb Recipe - Southern Cravings (2024)

FAQs

Does lamb leg get more tender the longer you cook it? ›

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.

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).

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!

Because the bone acts as an insulator, boneless lamb leg cooks faster than bone-in lamb leg, giving you more leeway in terms of hitting the exact doneness you want, but this advantage can be easily mitigated with careful monitoring and a good thermometer.

The leg and rack are the most tender cuts of meat on a lamb, and are at their best when roasted. Roasting is a "dry heat" cooking method, meaning that you do not add any liquid to the meat as you cook it.

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.

Immediately putting this large cut of meat in the oven after removing it from the fridge can lead to uneven cooking and an even longer cooking time. To ensure a leg of lamb cooks evenly, remove it from the fridge and let it sit at room temperature for an hour before cooking.

Lamb should be roasted 20 mins per 450g/lb, plus an extra 20 mins. Weigh meat prior to roasting to determine cooking times. Cook at 220C/200C fan for the first 20 mins and then 190C/170C fan for the remaining time.

As the end of the cooking time draws near, press the outside centre of your lamb lightly with tongs or a clean fingertip to judge its degree of doneness. As a rough guide: Very soft = rare – bright red, raw centre. Soft = medium rare – pink inside with a red centre.

By removing the bone from the leg of lamb and flattening it out you can cook it more quickly.

Should I salt leg of lamb before cooking? ›

No matter how you decide to cook your beautiful cut of grass-fed lamb, seasoning is the essential first step. Start by setting your cut of lamb onto a wire rack set into a rimmed baking sheet and sprinkle generously on all sides with kosher salt.

Lamb can also be prepared for service without cooking

For our quick cuts 1-2 hours is enough, but our shoulder and leg cuts would need at least 8 hours or overnight. This way you can be economical with the cuts you use and still achieve that tender result.

A rare, or pink, lamb chop that has been seared well on the outside should be fine because any bacteria on the outer surface will have been killed by the heat. But minced or diced lamb or mutton should never be served pink. It needs to be thoroughly cooked and browned. The same goes for burgers.

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.

It depends on the cut. If you cook a lamb shank low and slow, it will become more tender as long as you don't let it dry out. A lamb chop, on the other hand, will reach optimum tenderness at medium rare. After that it will become tougher as it cooks.

Note: Most slow cookers only have a high or low setting. If you find that your lamb is still tough after these times, test the meat in 30 minute intervals until it's fork tender.

Slow-cooking lamb requires patience. While cooking, resist the urge to keep checking on the lamb and refrain from opening the oven or slow cooker. Opening the lid or foil too often will lower the temperature and extend the cooking time, making the meat less juicy and tender.

Lower temp = more succulent meat – Tough cuts like lamb shoulder need slow-cooking to tenderise them. The lower the roasting temperature, the less total moisture evaporation and thus juicier meat.
