1. Preheat the oven to Gas mark 4-5, 180-190°C, 350-375°F.

2. Place the lamb on a chopping board and with a sharp knife make several slits over the surface of the joint, taking care not to cut through the butcher’s string or elasticated meat bands. Season and place in a large shallow dish. In a small bowl; mix the Thai marinade ingredients together and spread over the surface of the joint. Cover and marinate for 2 hours or overnight in the refrigerator.

3. Place the joint on a metal rack in a large non-stick roasting tin and open roast for the preferred calculated cooking time. Cover the joint with foil if browning too quickly.

4. One hour before the end of the cooking time remove the joint and rack from the oven, add the vegetables, drizzle with the oil and position the joint on the top. Return to the oven and cook uncovered for the remainder of the cooking time.

5. Serve the lamb with roasted vegetables garnished with the fresh thyme leaves.

Tip: For a quick mid-week treat why not use a mini lamb roasting joint instead that will cook in under 1 hour?
