A simple yet elegant herb-crusted roasted leg of lamb recipe that delivers tender, juicy meat with a flavorful crust, perfect for special dinners and celebrations.

Ingredients

Scale
  • 4 to 5 pounds leg of lamb, bone-in or boneless
  • 2 tablespoons fresh rosemary, finely chopped
  • 2 tablespoons fresh thyme, chopped
  • 2 tablespoons fresh parsley, chopped
  • 4 to 5 garlic cloves, minced
  • Zest of 1 lemon
  • 3 tablespoons extra virgin olive oil
  • 1 tablespoon kosher salt
  • 1 teaspoon freshly ground black pepper
  • 1 tablespoon Dijon mustard (optional)

Instructions

  1. Remove the lamb from the fridge about 30 minutes before cooking to bring it to room temperature. Pat dry thoroughly with paper towels.
  2. Score the fat layer in a crisscross pattern about 1/4 inch deep without cutting into the meat.
  3. In a mixing bowl, combine rosemary, thyme, parsley, garlic, lemon zest, kosher salt, and black pepper. Add olive oil and Dijon mustard if using, mixing into a thick paste.
  4. Rub the herb mixture all over the lamb, pressing it into the fat and scoring marks to coat evenly.
  5. Preheat the oven to 425°F (220°C).
  6. Place the lamb fat-side up on a rack in a roasting pan. Roast at 425°F for 20 minutes to brown the crust.
  7. Reduce oven temperature to 350°F (175°C) and continue roasting for about 15 minutes per pound (60-75 minutes for 4-5 lb) until internal temperature reaches 135°F (57°C) for medium-rare.
  8. Remove from oven and tent loosely with foil. Let rest for 15-20 minutes to allow juices to redistribute.
  9. Carve the lamb against the grain into thin slices and serve.

Notes

Bring lamb to room temperature before cooking for even roasting. Score the fat to help seasoning penetrate and crisp the crust. Use a meat thermometer to avoid overcooking. Let the meat rest after roasting to keep it juicy. For stronger flavor, rub herb mixture at least an hour or overnight before cooking. You can substitute parsley with mint or add spices like red pepper flakes for variation. Slow cooker adaptation possible but crust won’t be as crispy.
