Ingredients

  • 4 anchovy fillets
  • 4 garlic cloves, thinly sliced
  • Finely grated zest of 2 lemons
  • 1 tablespoon chopped marjoram
  • 1 teaspoon freshly ground pepper
  • 1 cup pitted green olives, such as Picholine
  • 1/3 cup extra-virgin olive oil
  • One 7-pound, bone-in leg of lamb

Method

  • Preheat the oven to 450.
  • In a food processor, combine the anchovies, garlic, lemon zest, marjoram and pepper and pulse until finely chopped.
  • Add the olives and pulse until finely chopped.
  • With the machine on, add the olive oil and process to a coarse paste.
  • Place a rack in a roasting pan and set the lamb on top.
  • Slather the lamb with the olive paste and roast on the lowest rack of the oven for 20 minutes.
  • Reduce the temperature to 350 and roast the lamb for about 1 hour and 10 minutes longer, until an instant-read thermometer inserted into the thickest part of the meat registers 125.
  • Let rest 15 minutes before carving.
  • Pour any accumulated juices into a bowl and serve with the lamb.
