  • 1 tablespoons salt
  • 2 tablespoons olive oil

  • Reduce the oven temperature to 300ºF (150ºC). Add the crushed garlic cloves and sliced onions to the pan. Continue roasting for another 20 minutes, or until the lamb reaches the desired level of doneness. For medium (pink), the internal temperature should be 55ºC. Remove the lamb from the oven, cover it with foil, and let it rest for 15 minutes.

Notes

  • Meat thermometer: Use it to get the perfect doneness. For medium-rare, aim for 55ºC (130ºF). If you prefer medium, go a bit higher—about 60ºC (140ºF).
  • Garlic prep: Crush the garlic cloves but don’t mince them. They roast better and won’t burn.
  • Rest time: Let it rest under foil before carving so the juices don’t run out all over your cutting board.
  • One-pan meal: Add potatoes or carrots to the roasting pan if you want an all-in-one dinner.
  • Rosemary: Fresh rosemary is best, but dried works too—just use a bit less.
  • Lamb cut: Bone-in or boneless leg of lamb both work, but boneless is easier to carve and often cooks faster.

Storage and Reheating Instructions

  • Fridge: Let the roast leg of lamb cool completely, then store it in an airtight container in the fridge for up to 4 days.
  • Reheat:  To reheat, cover slices with foil and warm them in the oven at 300ºF (150ºC) until heated through. Add a splash of water or pan juices to keep it moist.  
  • Freeze: You can also freeze the lamb (sliced or whole) for up to 2 months. Just wrap it tightly in foil or a freezer bag, then thaw in the fridge overnight before reheating.
