Choosing the Right Marinade
When it comes to marinades, there are countless options to choose from. However, a classic Greek yogurt and herb marinade is an excellent choice for a leg of lamb. The acidity in the yogurt helps break down the proteins, while the herbs add a fresh and aromatic flavor. You can also experiment with other marinades, such as a mixture of olive oil, garlic, and lemon juice. Whatever marinade you choose, make sure to coat the lamb evenly and refrigerate it for at least 2 hours, or overnight, to allow the flavors to penetrate deep into the meat.
Cooking Time and Temperature
The cooking time and temperature for a leg of lamb on a gas BBQ will depend on the size and thickness of the meat. A good rule of thumb is to cook the lamb at 400°F (200°C) for 20-25 minutes per pound, or until it reaches an internal temperature of 145°F (63°C) for medium-rare. It’s essential to use a meat thermometer to ensure the lamb is cooked to your desired level of doneness.
BBQ Lid Open or Closed
When cooking a leg of lamb on a gas BBQ, it’s essential to decide whether to cook with the lid open or closed. Cooking with the lid closed helps retain moisture and promotes even cooking. This is especially important when cooking a larger piece of meat like a leg of lamb. However, if you prefer a crispy crust on the lamb, cooking with the lid open may be the way to go.
Slicing and Resting
After cooking the lamb, it’s essential to let it rest for 10-15 minutes before slicing. This allows the juices to redistribute, ensuring a more tender and flavorful dish. You can also let the lamb rest for longer, up to 30 minutes, if you prefer a more tender texture.
Bone-In Leg of Lamb
A bone-in leg of lamb can be cooked on a gas BBQ, but it’s essential to adjust the cooking time and temperature accordingly. A bone-in leg of lamb will take longer to cook than a boneless one, so make sure to increase the cooking time by 10-15 minutes.
Side Dishes
A leg of lamb pairs well with a variety of side dishes, including roasted vegetables, quinoa salad, and grilled asparagus. You can also serve it with a side of tangy tzatziki sauce or a drizzle of olive oil and lemon juice.
Rub Instead of Marinade
While a marinade is an excellent way to flavor a leg of lamb, you can also use a rub instead. A rub is a mixture of spices and herbs that you apply directly to the meat. You can use a store-bought rub or make your own using a combination of ingredients like paprika, garlic powder, and thyme.
Checking Doneness
To check if the lamb is cooked to your desired level of doneness, use a meat thermometer. Insert the thermometer into the thickest part of the meat, avoiding any fat or bone. The internal temperature should read 145°F (63°C) for medium-rare, 160°F (71°C) for medium, and 170°F (77°C) for well-done.
Cooking Frozen Lamb
A leg of lamb can be cooked from frozen, but it’s essential to adjust the cooking time and temperature to prevent overcooking. A good rule of thumb is to cook the lamb at 350°F (175°C) for 30-40 minutes per pound, or until it reaches an internal temperature of 145°F (63°C) for medium-rare.
Troubleshooting
If the lamb is cooking too quickly or slowly on the BBQ, there are a few things you can check. First, make sure the BBQ is preheated to the correct temperature. If the lamb is cooking too quickly, you can try reducing the heat or covering it with foil to slow down the cooking process. If the lamb is cooking too slowly, you can try increasing the heat or using a fan to circulate the air.
❓ Frequently Asked Questions
What is the best way to thaw a frozen leg of lamb for grilling?
The best way to thaw a frozen leg of lamb is to place it in the refrigerator overnight or thaw it in cold water, changing the water every 30 minutes. Never thaw a frozen leg of lamb at room temperature, as this can lead to bacterial growth and foodborne illness.

Can I cook a leg of lamb on a gas BBQ with a lid that’s not fully functional?
While it’s possible to cook a leg of lamb on a gas BBQ with a lid that’s not fully functional, it’s not recommended. A fully functional lid is essential for even cooking and preventing flare-ups.
