• When you are ready to start you will need to get your Weber Q ready for convection oven cooking. Place a new convection tray onto the grill, noticing that Weber Q trays will line up with the holes on the grill, this will prevent movement. Then place a trivet on top of the convection tray.
• Turn on the gas bottle that is connected to your Weber Q and turn both control knobs to the START/HI position. Then, push the ignition switch to fire up the BBQ. If you have a Weber Q Baby, then turn the control knob to START/HI. If you have 2 meat probes handy, then this is the time to rest the first probe onto the convection tray. This will give you the temperature of the Weber Q BBQ. Run at this setting for 10-15 minutes to get the Weber Q nice and hot, with the lid closed.
• While your Weber Q is heating up, now is the time to prep your leg of lamb. Begin by peeling and cutting fresh garlic cloves into small 1cm pieces. You will need about 12-14 small blocks of garlic.
• Cut 8-10 small pieces of fresh rosemary.
• Make 8-10, 2cm cuts across the lamb and place 1 piece of sliced garlic and rosemary into each cut. Make sure to push the garlic in, but leave a small amount of rosemary sticking out, so that you can remove it later upon serving.
• Baste olive oil over the leg of lamb, making sure the entire leg is covered. Then sprinkle salt and pepper as desired.

Roasting the Leg of Lamb

• Place the lamb onto the centre of the Trivet, and if the Weber is hot enough you will hear it sizzle. Now is the time to insert your other meat probe into the centre of the lamb. If your roast has a bone, make sure the probe does not make contact with it, as this will give you a false internal temperature reading. Make sure you remember to close the lid to stop heat from escaping.
• If you have the Family Q series turn down the small control knob to the LOW position and leave the large control knob in the HI position. If you have a Weber Q Baby, then don't change any positions on the control knob and continue with this method. Leave your leg of lamb for at least 25 to 30 min at this setting and please avoid the temptation of lifting the lid to check if the lamb crackle process has begun.
• After 30 minutes the lamb will already show signs of crackle. Next, you need to turn the smaller control knob to the OFF position and the large control knob to the ROAST (middle) position.

  For the Baby Q, turn the single gas control knob to the medium (middle) roast position.
• The temperature will be high at first, but turning the control knob to the medium position will soon bring the temperature down. And don't worry, you won't burn the roast. Keep the roast at between 190°C to 230°C or 375°F to 450°F at all times. You can maintain this easily by keeping an eye on your temperature and adjusting the control between HI and Medium as required.
• Once the internal temperature of the lamb has reached 45°C or 113°F, it is time to add any vegetables that are required for roasting. Place your vegetables around the roast lamb so they can absorb the smokey aroma and flavours of the roast lamb.
• Monitor the temperature of the Weber Q and meat throughout the cooking process with your meat probe. Once the internal temperature of the lamb has reached 155°F or 68°C, lift the lid and remove the meat probe, making sure to wear gloves so as not to burn yourself. Place the lamb onto a serving plate and set aside to rest for 15 to 20 minutes. This will bring the internal temperature to around 160°F or 71°C. After resting carve your lamb and serve with roast vegetables. ENJOY!
