Instructions

  1. Remove the lamb leg from the fridge at least 60 minutes before cooking.
  2. Preheat oven to 250°F.
  3. Combine olive oil, garlic, parsley, rosemary, mustard, thyme, salt, and pepper in a small bowl.
  4. Dab the lamb dry with paper towels. Rub the lamb with the herb rub.
  5. Place in a rimmed baking sheet and bake until internal temperature reaches 110-115°F, about 60-80 minutes depending on size and shape.
  6. Remove from the oven and rest 20 minutes. While the lamb roast is resting, turn the oven up to 475°F.
  7. Place the lamb roast on a clean pan back into the oven and cook until it reaches 125-130°F (or as desired per the temperatures below), about 15-20 minutes. *See note. The temperature will increase about 10°F while resting.
  8. Rest 10-15 minutes before cutting and serving.

Notes

  • Medium Rare 135°F Dark pink centerMedium 145°F Pink centerMedium Well 155°F Browned center with very little pink
  • A meat thermometer is essential for this recipe. Cooking times can vary based on the type of pan and the shape/size of the roast.
  • Allow the lamb come to room temperature before roasting.
  • Remove the lamb from the oven at 110-115°F for the first cook. When you turn the oven up to a high temperature the lamb will become get a browned crust.
  • The second cook is at a very high temperature to form a nice crust so you may experience some smoking in the oven due to the oil and juices in the pan. To reduce smoking, transfer the lamb roast to a clean pan. If the lamb has a browned crust to your liking but hasn't reached 125°F yet, you can turn the oven off and leave it in the oven until it reaches the desired temperature.
  • Be sure to rest before cutting.
  • Do not overcook. The lamb leg will continue to rise 5-10°F as it rests so be sure to take it out early.
