Ingredients

  • 1 boneless leg of lamb, rolled and tied (3–4 pounds)
  • 3 tablespoons olive oil
  • 4 garlic cloves, minced or slivered
  • 1 tablespoon fresh rosemary, chopped
  • 1 tablespoon fresh thyme or oregano (or 1 teaspoon dried)
  • Zest and juice of 1 lemon
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 cup red wine or beef broth (optional, for pan juices)
  • 2 carrots, chopped (optional)
  • 1 onion, chopped (optional)
  • 2–3 potatoes, chopped (optional)

Instructions

  1. Preheat the oven to 275°F (135°C) and let the lamb sit at room temperature for 30 minutes.
  2. In a small bowl, mix olive oil, garlic, rosemary, thyme, lemon zest, salt, and pepper into a paste.
  3. Pat the lamb dry and rub the herb paste all over the meat, pressing it into the surface.
  4. Place the lamb in a roasting pan, fat side up. Add optional vegetables around it, drizzled with olive oil and seasoned.
  5. Roast uncovered for 3.5 to 4 hours, or until internal temperature reaches 135°F for medium-rare or 145°F for medium.
  6. Remove the lamb and let it rest, loosely covered, for 15–20 minutes.
  7. Meanwhile, deglaze the pan with red wine or broth, scraping up browned bits to create a simple jus.
  8. Slice the lamb and serve with pan juices drizzled on top.

Notes

  • Stuff the lamb with extra garlic, herbs, or spinach before tying for more flavor.
  • Use Dijon mustard in the rub for a zesty crust.
  • Finish under the broiler for a crisp, browned edge.
  • Drizzle honey or balsamic into the herb mix for subtle sweetness.
  • Reheat slices gently with broth to maintain moisture.
