grilled leg of lamb on a serving plate with sauce

Marinated Grilled Leg of Lamb

When thinking of summer grilling, a boneless leg of lamb is probably not usually what comes first to mind.  Lamb has somehow gotten a bad rap of having a very strong flavor and taste. This recipe I believe will change the minds of even the biggest lamb skeptics out there. The boneless leg of lamb is “ butterflied” which is a culinary term to cut a thick piece of meat into a thinner thickness. The lamb is marinated and then perfectly grilled. Smoky charred on the outside, juicy on the inside and, served with a simple fresh herb pistou sauce, this just may make it to the top of your outdoor grilling repertoire!

Ingredients
  

  • 1 4- pound Boneless Leg of Lamb butterflied*

Rub:

  • 3 cloves Garlic peeled
  • 1 cup Loosely Packed Parsley Leaves
  • 4 T Fresh Thyme Leaves or Rosemary

Pistou:

  • 3 cloves Garlic peeled
  • 1 cup Loosely Packed Parsley Leaves
  • 3 cups Basil Leaves
  • ½ cup Olive Oil
  • Salt & Pepper

Instructions
 

  • *You can ask your butcher to butterfly the boneless leg of lamb for you or you can do it yourself by placing the leg of lamb on a cutting board, using a boning knife to “butterfly” the thickest part of the leg areas so that the overall thickness of the meat is 1 – 1½” thick.
  • If necessary, trim any large pieces of fat off the meat.
  • I then cut the leg into 2 pieces so that it is easier to handle. Set aside.

  • Approximately 1 ½ hour before want to serve the lamb, Remove the meat from the bag or container, place on a platter and let sit on your counter for 30 minutes. Preheat your BBQ grill.
  • Right before grilling, pat the meat dry using paper towels dry. Season with salt and pepper.

  • Place the meat fat side up on the grill over “medium-high” heat. Let the meat achieve a nice sear before flipping it over, about 6 minutes.

  • Flip to the other side. You may need to occasionally flip or turn the meat over if the fat should catch on fire and flare up.

  • Continue cooking until the thermometer reads 125º-130º F for medium rare, about and additional 10-15 minutes, depending on the thickness of the meat and the temperature of your grill.
  • Remove from grill and place on platter. Cover loosely with aluminum foil. Let it rest for 15-20 minutes.
  • Slice the lamb against the grain i.e. with the knife slicing perpendicular to the direction of the grain in the meat.

  • Add the olive oil, pulse until smooth, season with salt and pepper. This sauce can be made 4 days ahead, but remove from refrigerator a hour before serving.

Notes

TIPS & TRICKS
– If you have the lamb butterflied by the butcher, make sure to ask to have it cut so that the overall thickness of the meat is 1- 1½ inches, this will make the cooking process much easier and insure that the meat is cooked evenly.
– You can make the pistou directly after you make the rub, so that you don’t have to wash the food processor twice.
– Left over grilled lamb makes the most fantastic sandwiches or tacos!
