Ingredients
  

  • 1 leg of lamb bone-in
  • 6 cloves garlic peeled
  • 3 tablespoons fresh rosemary leaves
  • 1 teaspoon dried thyme
  • 2 teaspoons kosher salt
  • 1 teaspoon ground black pepper freshly
  • ¼ teaspoon red chili flakes
  • ¼ cup olive oil

Instructions
 

  • Preheat oven to 425°F (220°C). Give it time to fully heat while you prepare the lamb.
  • Trim any tough silver skin or extra fat, leaving a thin fat layer on top to keep the meat moist. If the bone isn’t already Frenched (cleaned), you can do that now for a neater look.
  • Score the surface of the lamb in a shallow crosshatch pattern, about ¼-inch deep, to help the seasoning stick.
  • Combine garlic, rosemary, thyme, chili flakes, salt, pepper, and olive oil in a food processor. Blend into a chunky paste.
  • Rub the paste all over the lamb, making sure to get it into the cuts and around the bone.
  • Let the lamb rest at room temperature for 30–45 minutes so it roasts evenly.
  • Place the lamb in a roasting pan and roast at 425°F for 20 minutes to brown the outside.
  • Lower the oven to 300°F and continue roasting for 1½ to 2 hours, or until the internal temp reaches 145°F for medium.
  • Remove from oven, loosely cover with foil, and let rest 15–20 minutes before slicing. This keeps the meat juicy as it finishes cooking from residual heat.

Notes

Chef Jenn's Tips

  • To French the bone: cut through the meat around 1 inch from the end of the bone, then scrape away any sinew or fat to expose a clean section of bone.
  • Use a meat thermometer for best results—don’t rely on guesswork.
  • For a more golden crust, place the lamb under the broiler for 3–4 minutes at the end. Watch carefully to avoid burning.
  • Save the pan juices. You can reduce them on the stove for a quick sauce.
