Roasting a leg of lamb is a simple way to produce a flavourful and elegant main course.
In this recipe, we will walk you through the steps necessary to make a perfect roast leg of lamb.
How To Make Roast Leg of Lamb
The key to success is to start with a good quality cut of meat and to cook it slowly so that the flavour has a chance to develop.
Remove the leg of lamb from the fridge and leave it at room temperature for about 1 hour before preparing. This will help to ensure that the meat cooks evenly.
Prepare The Leg Of Lamb Marinade
To begin, preheat the oven to 180C/160C Fan/Gas Mark 4.
Then, rub the leg of lamb with a mixture of olive oil, garlic, and herbs. Optionally add in some chopped onions and bashed garlic cloves.
Roast for about an hour and a half (more details on the leg of lamb cooking times below).
When the meat is cooked through, remove it from the oven and let it rest for 10 minutes before carving. This will give the juices time to redistribute throughout the meat, resulting in a juicy and delicious final product.
What Is The Cooking Time For A Roast Leg Of Lamb?
