Preparation instructions

Prepare the marinade and lamb leg

1In a bowl, mix olive oil, crushed garlic, chopped rosemary and thyme, lemon juice, honey, salt, and pepper. Rub this mixture all over the lamb leg thoroughly, getting under the skin where possible for more flavor. Let it marinate for at least 1 hour at room temperature or preferably overnight in the refrigerator. This enhances flavor and tenderness.

Preheat and prepare your BBQ for slow cooking

2Set up your barbecue for indirect heat cooking method by lighting coals on one side only, or if gas BBQ, only turn on burners on one side. Maintain the BBQ temperature around 120-130°C (250-270°F). This slow roasting temperature cooks the lamb gently and keeps it juicy.

Place lamb leg on the grill

3Put the marinated lamb leg on the side of the grill without direct heat. Close the BBQ lid and cook slowly for about 4 hours, turning the leg every hour to cook evenly. Use a meat thermometer to check internal temperature to ensure safety and doneness.

Check internal temperature for food safety

4Insert a meat thermometer into the thickest part of the lamb leg without touching the bone. The safe minimum internal temperature for lamb is 63°C (145°F) with a 3-minute rest period before serving. Do not cut into the meat to check doneness prematurely as this releases juices and dries out the meat.

Rest the lamb leg

5Once the internal temperature reaches 63°C, remove the lamb from the BBQ and cover loosely with foil. Let it rest for at least 15 minutes; this allows juices to redistribute making the meat tender and juicy.

Carve and serve

6After resting, carve the lamb leg against the grain into slices. Serve with your choice of sides such as grilled vegetables or a fresh salad. Enjoy your flavorful, safely cooked slow BBQ lamb leg!

FAQ

Can I use a boneless lamb leg instead?

Yes, you can use a boneless lamb leg. Adjust cooking time slightly as boneless cuts may cook faster, and always check the internal temperature.

What if I don’t have a meat thermometer?

While a thermometer is the safest way to ensure doneness, you can check by cutting a small slice; the meat should be juicy and slightly pink in the center for medium rare. However, investing in a thermometer is highly recommended.

Can I prepare the lamb leg indoors?

Yes, you can slow cook the lamb leg in an oven at 130°C (265°F) for about 4 hours using the same preparation and resting method.

How long can leftovers be stored?

Cooked lamb can be stored in the refrigerator for up to 3 days in an airtight container. Reheat thoroughly to at least 74°C (165°F) before consuming.
