  1. Step 1

    Preheat oven to 200°C. Place lamb on a board. Pat dry with paper towel.
  2. Step 2

    Process breadcrumbs, garlic and mint leaves in a food processor until finely chopped. Add lemon rind and 2 tbs oil. Pulse to combine. Season.

  3. Step 3

    Brush lamb with Dijon mustard. Pat breadcrumb mixture all over lamb, pressing firmly to ensure it sticks. Carefully place lamb in a large roasting pan. Roast for 30 mins. Toss potatoes in remaining oil. Season with salt. Arrange around lamb with extra garlic cloves, lemon wedges and thyme sprigs. Roast for 1 hour. Rest lamb, covered with foil, for 15 mins.
