Ingredients

Roast Leg of Lamb:

  • 5 pound boneless leg of lamb
  • 3 Tablespoons kosher salt
  • 3-4 sprigs Rosemary finely chopped (about 3 tablespoons)
  • 2 teaspoons black pepper
  • 3-4 cloves garlic peeled, and sliced into thin slivers

Instructions

Rosemary Rub

  • Mix salt, rosemary and pepper in a small bowl. This is important because you don't want cross-contamination. 

Roasting Lamb

  • Pre-heat oven to 500 degrees F. Adjust oven racks so that lamb will roast on the bottom third of your oven. 
  • With a long, thin knife, make several deep cuts into the roast. Put a sliver of garlic into each cut. Coat all sides of meat with rosemary/salt rub (discard any un-used herb rub).
  • Roast lamb, fat side up, at 500 degrees for 20 minutes.
  • Reduce oven to 375 degrees and continue roasting until internal temperature reaches the proper temperature to your liking.
  • For medium rare, remove at 135 degrees F. (It will continue cooking after you remove it from the oven another 10-15 degrees).
  • If you prefer yours rare, pull at 130 degrees F. For medium lamb, pull at 145 to 150 degrees F. 

Notes

  • Figure on 6-8 ounces of meat per person for a boneless leg of lamb.
  • Cooking time will range from 20 to 25 minutes per pound depending on desired temperature.
  • For medium rare, remove at 135 degrees F. (It will continue cooking after you remove it from the oven another 10-15 degrees).
