Ingredients

  • 3 3/4 cups cubed day-old bread
  • 3 tablespoons olive oil
  • 1 large shallot
  • 2 ounces pancetta, finely diced
  • 2 ounces mortadella, finely diced
  • 8 fresh sage leaves, finely chopped
  • 1 cup lamb broth (see headnote)
  • 3/4 cup freshly grated Parmigiano-Reggiano cheese
  • Freshly ground pepper
  • One 4 1/2 - to 5-pound leg of spring lamb, butterflied, with the shank bone left in
  • Kosher salt

Method

  • Preheat the oven to 400.
  • Toss the bread with 1 1/2 tablespoons of the olive oil.
  • Spread the bread on a baking sheet and toast in the oven for 12 to 15 minutes, until dry and brown.
  • In a small skillet, warm the remaining 1 1/2 tablespoons olive oil.
  • Add the shallot, pancetta, mortadella and sage and stir over moderate heat until the shallot is soft, about 5 minutes.
  • In a bowl, combine the toasted bread with the lamb broth and let stand for 5 minutes.
  • Add the pancetta mixture along with the cheese and mix well.
  • Season the stuffing liberally with pepper.
  • Open the leg of lamb and season the meat with salt and pepper.
  • Spread the stuffing over the meat and then re-form the leg, patting it into an even cylindrical shape.
  • Tie the roast at 1-inch intervals and place in a small roasting pan.
  • Season with salt and pepper.
  • Roast the leg of lamb on the top shelf of the oven for 1 hour and 10 minutes, basting with the pan juices every 20 minutes.
  • The meat is medium-rare when the internal temperature reaches 125.
  • Let the roast rest for about 10 minutes, then carve and serve with the pan juices.
  • (If the pan is dry, deglaze it by stirring in approximately 1 cup of water and boiling until the juices are well reduced and flavorful.)
