Ingredients Method Notes

Ingredients
  

  • 1 bone-in leg of lamb (6-7 pounds), trimmed
  • 6 garlic cloves, minced
  • 3 tablespoons fresh rosemary, chopped
  • 2 tablespoons fresh thyme, chopped
  • 2 tablespoons olive oil
  • 2 teaspoons salt
  • 1 teaspoon black pepper
  • 1 tablespoon Dijon mustard
  • 2 tablespoons breadcrumbs
  • 1 lemon, juiced
  • 2 tablespoons butter, softened

Method
 

  1. Step 1: Preparation
    Remove lamb from refrigerator 1 hour before cooking to bring to room temperature. Preheat oven to 450°F (230°C).
  2. Step 2: Create Herb Paste
    In a small bowl, combine minced garlic, chopped rosemary, thyme, olive oil, salt, pepper, and Dijon mustard. Mix until it forms a paste-like consistency.
  3. Step 3: Score and Season
    Using a sharp knife, make small slits all over the lamb, about 1 inch apart. Rub the herb paste all over the lamb, working it into the slits. Sprinkle breadcrumbs over the surface.
  4. Step 4: Initial Roasting
    Place lamb in a roasting pan and roast at 450°F for 20 minutes to develop a crust.
  5. Step 5: Reduce Temperature
    Lower oven temperature to 325°F (165°C) and continue roasting for approximately 2 hours, or until internal temperature reaches 130°F for medium-rare.
  6. Step 6: Rest and Finish
    Remove from oven and tent with foil. Let rest for 15 minutes. Drizzle with lemon juice and dot with butter before carving.
  7. Step 7: Carving
    Carve against the grain into thin slices and serve immediately.
