Method

  1. Using the point of a sharp knife make small incisions all over the lamb, then poke a slice of garlic into each hole. Cut the rosemary into smaller sprigs and push them into the incisions too. Cover and chill for at least 2 hours, preferably overnight.
  2. Take the lamb out of the fridge 1hr before roasting to allow to come to room temperature. Heat oven togas 7, 220°C, fan 200°C. Place the chopped onion and carrot in a large roasting tin, then sit the lamb on top, season well and drizzle over the oil. Roast for 15 mins, then turn down to gas 5, 190°C, fan 170°Cand roast for a further 1hr 20 mins. Remove the lamb, cover lightly with foil and leave to rest in a warm place for 30-45 mins. (Now’s the time to pop your potatoes in the oven).
  3. Meanwhile make the pesto sauce. Boil the kettle and pour over the peas, leave to stand for 1-2 mins. Drain the peas, then run under cold water. Once cool transfer to the small bowl of a food processor. Add the remaining ingredients and blend to a smooth paste. Season and transfer to a serving dish.
  4. Strain any lamb juices from the roasting tray into a small saucepan. Add any resting juices and heat through. Slice the lamb and serve with the roasting juices and pea and mint sauce.
