Among the popular cuts of lamb like shoulder roast, loin, chops, etc the leg of lamb is the most popular and widely devoured.

The most common methods of cooking a leg of lamb are grilling (barbequing), braising, and roasting. All the methods have their advantages and give an authentic taste to the meat to be prepared. It is must be kept in mind that the time that is taken to cook the meat always depends on the quantity required to be cooked.

For a medium done 1 kg leg of lamb, it could take about 1 hour and 15 minutes to cook it completely.

Cooking times ideally depend on the quantity of meat to be cooked. However, the temperature also has an important role to play. Thus, the time taken by different weights for the leg of lamb to cook evenly would vary depending on the temperature at which it is being cooked.

Slow cooking the leg pieces helps in retaining moisture in the meat pieces which makes the leg of lamb tender, moist, and flavorful.

Thus, a boneless leg could 30 – 45 minutes for a 1 kg meat, while a whole leg of lamb typically takes 50 – 60 mins to get cooked.

Also, just like beef, pork, and other meats, lamb needs to rest after cooking to allow the juices inside the meat pieces to settle back, making it meatier, juicer, and easier to carve it.

Sundays become even better when one is cooking a leg of lamb for dinner. It is a succulent dish that people love to have on any occasion. Lamb meat typically takes a bit longer to cook but this makes them even more delicious, juicy, and more tender in taste. The leg of lamb can be cooked as long as it does not dry out.

A 1 kg leg of lamb takes approximately 1 hour 15 minutes to get cooked and reach its optimum tenderness at medium-rare doneness. If it is cooked beyond this time, the meat might get tougher, chewy, and unappetizing.
