I’ll show you how to roast lamb perfectly. A delicious leg of lamb roast is only about 1 1/2 hours and a few ingredients away!


  • 1 tsp. garlic powder
  • 1 tsp. pepper
  • 1/2 tsp. salt
  • 1 (4 1/2- to 5-lb.) boneless leg of lamb
  • 3 ribs celery (optional)


  • Preheat the oven to 350°F.
  • Mix together the garlic powder, pepper, and salt.
  • Trim any fat on the lamb to a thin layer. Unroll the lamb and, if you want, trim any silver skin from the inside (see note). Sprinkle with about 1/3 of the seasoning mixture. Roll the lamb back up into a log and tie with kitchen twine every 1 1/2 to 2 inches. Sprinkle with the remaining seasoning mixture.
  • Put the lamb on a rack in a roasting pan fat side up. If you don’t have a rack use 3 stalks of celery lying side by side.
  • Roast until the internal temperature is 125°F for medium-rare to 150°F for well done, 15 to 25 minutes per pound (the temperature will increase as the meat rests).
  • Cover the roasting pan with foil and let rest for 30 minutes.
  • Meanwhile, increase the oven to 475°F.
  • Roast uncovered for another 10 minutes, until the meat is nicely browned.
  • Carve and serve immediately.
