What is a butterflied leg of lamb? A butterflied leg of lamb is a boneless leg that's been opened out and flattened to an even thickness. Removing the bone means it cooks faster and more evenly than a traditional whole roast, takes on marinades beautifully, and is far easier to carve which is why it's a favourite for the barbecue and for entertaining. How to cook a butterflied leg of lamb? On the barbecue: cook over medium heat for around 2530 minutes per side, turning occasionally, until cooked to your liking. In the oven: roast at 200C (fan 180C Gas Mark 6). For the best flavour, marinate generously with garlic, herbs and olive oil before cooking, and rest before slicing.
