Before you start:

We highly reccomend purchasing  a digital meat thermometer, which is an essential tool for any cook.


It’s important to note that cooking times and temperatures will vary depending on the size and internal temperature of your meat, as well as the oven temperature.


Therefore, it’s recommended to use cooking times and temperatures as a guide, but invest in a digital thermometer to ensure that your roast is cooked to your desired level of doneness.

Choosing your lamb:

When selecting lamb, look for a deep pink color with dry, white fat.


Step 1: Prepare the Leg of Lamb

Ensure the leg of lamb is brought to room temperature before cooking.

Do not remove excess fat from the leg, as it adds flavor and helps keep the meat tender.

Step 2: Preheat the Oven

Preheat the oven to 190˚C-220˚C.

Step 3: Season the Lamb

Season the leg of lamb with salt and pepper, or your preferred seasoning blend.

Step 4: Roast the Lamb

Place the seasoned leg of lamb in a roasting pan or baking dish.

Roast the lamb in the preheated oven for the recommended cooking time, based on its weight (approximately 45 minutes per kilogram).

Step 5: Baste the Lamb

Occasionally baste the lamb with the pan juices to keep it moist and flavorful.

Step 6: Check the Doneness

Use a meat thermometer to check the internal temperature of the lamb.


The desired doneness for pink in the middle is around

  • 55-59˚C  for medium
  • 60-66˚C  for medium
  • 67–74˚C for well done


Roast lamb should be served pink in the middle.


Adjust the cooking time accordingly.

Step 7: Rest the Lamb

Once the lamb reaches the desired doneness, remove it from the oven and let it rest for about 20 minutes under foil.


This allows the juices to redistribute and the meat to become tender.

Step 8: Carve and Serve

Carve the leg of lamb into slices or desired portions.


Serve the lamb with your favorite sides, such as roasted potatoes, vegetables, or mint sauce.


Enjoy the succulent and flavorful leg of lamb, cooked to perfection, with its tender texture and delicious taste.
