Here’s why you need to try butterflied lamb on the BBQ

Love the idea of cooking a leg of lamb but don’t want to heat up the kitchen? Here’s the answer: cook it on the BBQ. In fact, the BBQ will do some pretty magical things to your lamb – it adds an amazing smoky flavour, leaves the meat tender and juicy, and adds those beautiful chargrill lines for an impressive finish. We promise, once you’ve tried a BBQ leg of lamb, you’ll never look back.

Why go for a butterflied lamb leg?

A butterflied leg of lamb has had the bone removed so it sits (mostly) flat. That means it will cook evenly on the BBQ, and it will cook quicker than a traditional lamb leg. The even better news is, all the prep has been done for you – it comes bone out. There may be some fat on the top side; if you prefer, you can trim some of that.

The perfect BBQ butterflied leg of lamb marinade

There are some things that just make sense – pork and apple, strawberries and cream, garlic and butter … add to that lamb and mint. Our mint marinade for lamb makes the most of those fresh herby flavours and then goes even further with mustard and garlic. Other great herbs for lamb include oregano, rosemary and thyme. The must-know tip here is to make sure you use a shallow bowl to add the marinade to the lamb. Make sure the marinated butterflied lamb leg is totally coated, then let it work its magic in the fridge.

How to cook a butterflied lamb leg on the BBQ

As always, start with a clean BBQ when cooking butterflied lamb. Any charred bits from previous cooks can stick to your lamb and burn. Now preheat the BBQ to medium-high. Add the butterflied lamb to the grill and cook for 5 minutes each side – this seals in the juices. Then drop that heat to low and close the lid to help the heat circulate.

How long does it take to cook butterflied lamb

A 1kg butterflied lamb leg’s cooking time is a quick 30 minutes for medium-rare doneness. You can check the internal temperature with a meat thermometer – for rare look for 60°C, for medium go for 65°C and for well done aim for 70°C.

How to carve a butterflied leg of lamb

There’s no bone to cut around when carving a BBQ butterflied leg of lamb, so simply cut across the grain to ensure maximum juiciness. Then all you need is a drizzle of peppercorn and mint salsa … because more mint is never wrong with lamb!
