Instructions

  1. Step 1: Preheat oven to 325°F. Pat dry 4 pounds bone-in lamb leg and season all over with 2 teaspoons sea salt and 1 teaspoon black pepper, rubbing into the meat.
  2. Step 2: Finely chop 4 sprigs fresh rosemary and mince 6 garlic cloves. Mix with 3 tablespoons extra virgin olive oil and rub the mixture evenly over the lamb.
  3. Step 3: Place lamb in a roasting pan and roast uncovered for 2.5 to 3 hours, basting every 45 minutes with pan juices, until a meat thermometer reads 135°F for medium-rare.
  4. Step 4: Remove lamb and tent with foil to rest while preparing jus. Place roasting pan over medium heat, add 1 cup dry white wine and 1 cup beef broth, scraping browned bits from the pan.
  5. Step 5: Simmer sauce for 8 minutes until slightly reduced and flavorful. Strain jus and serve alongside sliced lamb.
