Ingredients

  • 3 lbs boneless leg of lamb, well trimmed and butterflied to an even 2-inch thickness
  • 8 garlic cloves, divided
  • 1/2 cup whole grain Dijon mustard
  • 1/2 cup extra virgin olive oil
  • 1/4 cup dry white wine
  • 2 tablespoons fresh rosemary, finely chopped
  • 2 tablespoons fresh lemon juice
  • kosher salt
  • fresh ground black pepper
  • fresh rosemary, for garnish
  • fresh parsley sprig, for garnish

Method

  • On a work surface, open lamb like a book; use the tip of a small knife, and make slits all over the lamb.
  • Peel and thinly slice 4 garlic cloves; insert garlic into the slits in the lamb.
  • In a food processor, combine remaining 4 garlic cloves, mustard, olive oil, wine, rosemary, and lemon juice; puree to a paste.
  • Spread half the paste on the lamb, then place seasoned side down in a glass baking dish; spread with remaining paste and cover with plastic wrap.
  • Marinate in the refrigerator overnight.
  • Allow an hour to bring lamb back to room temperature, then sprinkle generously with salt and pepper; roll lamb and tie with kitchen twine at 1-inch intervals.
  • Meanwhile, preheat oven to 375 degrees F.
  • Place lamb on a rack and roast to an internal temperature of 125 degrees F, about 45 minutes.
  • Let rest for 15 minutes, then slice thinly.
  • Place slices overlapping on a serving platter, drizzle with pan juices, sprinkle with salt and pepper, and decorate with fresh herb stems, if desired.
