Best Grilled Leg of Lamb with Olive Oil infused with Fresh Herbs 1  7 to 8 lb leg of lamb, butter flied For the Marinade : 2  Onions, peeled and sliced 8  Cloves of garlic, crushed 2  Cups dry white wine 1  Cup extra-virgin olive oil 1  Tablespoon chopped Thyme Fresh black pepper to taste Combine the onions, garlic wine, olive oil and herbs in a shallow dish, and then season with pepper to taste.  Place the lamb leg in the dish and turn over to coat well.  Cover and refrigerate for at least 8 hours up to over night. For the Herb infused Olive Oil: 1  Bunch fresh Parsley, rough chopped 1  Tablespoon Fresh Thyme, rough chopped 1  Tablespoon fresh Oregano, rough chopped 1  Clove garlic, rough chopped 1  Lemon 1 1/2  Cup extra-virgin olive oil Using a blender pulse the herbs and garlic together.  Squeeze in the juice from the lemon and then stream in the oil to produce a flavor, green oil.  Reserve. Preheat the grill.  Remove the lamb from the marinade and season with salt.  Over medium heat, place the lamb on the grill and cook until medium-rare, about 10 to 12 minutes per side.  Remove the lamb to a warm platter and cover with a piece of aluminum foil to keep warm.  Allow the lamb to rest for 10 minutes before carving to reabsorb the natural juices.  Remove the rested lamb to a cutting board, but reserve the platter.  Carve the lamb into slices and arrange back onto the platter.  Garnish with fresh herbs and drizzle with the infused olive oil.
