- Preheat the oven to 160C fan forced.
- Mix the chopped garlic, salt, rosemary and olive oil together in a small bowl to form a paste.
- Rub the paste generously all over the lamb, massaging gently.
- Place the marinated lamb onto a roasting dish. Fill the roasting dish with water. Cover the dish with aluminium foil.
- Reduce heat down to 110C fan forced and place the roasting dish in the oven. Cook slowly for 4 hours.
- After 4 hours, increase oven heat to 180C fan forced and remove aluminium foil. Cook for 1 hour.
- Place the chopped carrots, pumpkin, sweet potatoes, potatoes and parsnip onto a large, flat baking tray on a single layer. Season by sprinkling dried basil, salt and pepper. Drizzle with some olive oil.
- Place the veggies and potatoes in the oven to cook along with the lamb. Cook the veggies and potatoes for approx. 30 minutes – or depending on oven, until the potatoes are crunchy.
- Once the lamb is cooked, allow meat to rest for 10 minutes before carving and serving with roast veggies and potatoes. Drizzle the lamb juices from the roasting dish all over the carved meat and potatoes. Serve also with steamed peas, corn and brocolli if desired.
Edit 19/7/2010: I cooked this dish again last weekend for a group of guests with a lamb leg as well as a lamb shoulder. I must say, the lamb shoulder is a lot more tender and tasted divine! It’s got a little bit more fat in the meat therefore provides a really good, tender juiciness in the meat. I would highly recommend you use this recipe for the lamb shoulder next time around! The leg is still pretty good of course, but if you prefer a bit more taste of lamb fat, shoulder is the way to go.
We just served everything up on the kitchen island and got our guests to “help themselves” to the meat, gravy (using the juices from the lamb added with some flour), roast parsnip, garlic bread and green peas! It turned out to be quite a feast 🙂
