A simple, quick, and flavorful low-carb herb-crusted leg of lamb recipe perfect for weeknight dinners or special occasions. The herb crust locks in juiciness and delivers a rustic yet refined flavor.

Ingredients

Scale
  • 4 to 5 pounds leg of lamb, bone-in or boneless
  • 2 tablespoons fresh rosemary, finely chopped
  • 2 tablespoons fresh thyme, finely chopped
  • 2 tablespoons fresh parsley, finely chopped
  • 4 cloves garlic, minced
  • Zest of 1 medium lemon
  • 3 tablespoons extra virgin olive oil
  • 1 ½ teaspoons kosher salt
  • 1 teaspoon freshly ground black pepper
  • 1 tablespoon Dijon mustard
  • Optional: pinch of red pepper flakes

Instructions

  1. Preheat the oven to 425°F (220°C).
  2. Pat the leg of lamb dry with paper towels. Trim excess fat but leave some for moisture.
  3. Score the fat with shallow diagonal cuts about 1 inch apart.
  4. In a mixing bowl, combine rosemary, thyme, parsley, garlic, lemon zest, olive oil, Dijon mustard, salt, and pepper to form a thick herb paste.
  5. Rub the herb paste all over the lamb, working it into the scored cuts and all sides. Optionally marinate covered in the fridge for 1-2 hours or overnight.
  6. Place the lamb on a rack in a roasting pan and roast at 425°F (220°C) for 15 minutes to develop the crust.
  7. Reduce oven temperature to 350°F (175°C) and continue roasting for 45-60 minutes, depending on size and desired doneness. Use a meat thermometer to check for 135°F (57°C) for medium-rare or 145°F (63°C) for medium.
  8. Remove from oven and tent loosely with foil. Let rest for 15-20 minutes to redistribute juices.
  9. Carve against the grain and serve with low-carb sides.

Notes

If the herb crust browns too quickly, cover the lamb loosely with foil midway through roasting. Use a meat thermometer to avoid overcooking. Resting the meat is crucial for juiciness. Fresh herbs are preferred but dried can be used in reduced amounts. You can marinate the lamb overnight for deeper flavor.
