Cooking Directions:

Now, let's get into the method of preparing the Pesto Grilled Leg of Lamb:

  1. To make pesto, in a food processor, pulse the Parmesan until it resembles coarse sand. Transfer to a small bowl. To the food processor, add the walnuts, garlic, and a big pinch of salt. Process until a smooth paste forms, about 1 minute. Add the cheese and about half the oil and process until smooth. Tear the basil as you add it to the food processor. Pulse until finely chopped. Add the remaining oil and pulse until incorporated.
  2. Pat the lamb dry, then cut it at its crease (where the lamb is folded over) so it can lay flat. Rub the lamb all over with enough pesto to coat, which should be about half the pesto (reserve the extra pesto for a side dish; see headnote). Refrigerate for up to 8 hours to marinate.
  3. Prepare a charcoal or gas grill for two-zone cooking over medium-high heat. (For a charcoal grill, pour the coals on one side. For a gas grill, heat all burners covered on high, then reduce one burner to medium-high and turn off the other.) Clean the grates.
  4. Rub most of the pesto off the lamb. Grill the lamb over direct heat, flipping and rotating as needed for even cooking, until well browned and the meat registers 125°F to 130°F for medium-rare. This could take anywhere from 12 to 30 minutes depending on the size and shape of your meat. If the meat starts to char before it’s done, move it to the cooler part of the grill, cover the grill, and let it finish cooking over indirect heat.
  5. Rest for 10 minutes, then thinly slice against the grain.
