Ingredients

  • 1 cup basil leaves
  • 1/4 cup pine nuts
  • 1/4 cup freshly grated Parmesan cheese
  • 4 garlic cloves
  • 2 tablespoons hot water
  • 1/4 cup olive oil, plus more for burshing
  • 1 cup dried bread crumbs
  • One 1 1/2-pound butterflied and well-trimmed leg of lamb
  • Salt and freshly ground pepper
  • 1 medium eggplant, halved lengthwise and sliced crosswise 1/2 inch thick
  • 4 medium tomatoes, sliced 1/2 inch thick

Method

  • Preheat the oven to 425.
  • In a blender, combine the basil, pine nuts, Parmesan, garlic and water with 1/4 cup of the olive oil.
  • Blend, stopping and scraping the sides of the blender as necessary, until a thick paste forms.
  • Transfer the pesto to a bowl and stir in the bread crumbs.
  • Lay the lamb flat, boned side up, on a large work surface and season generously with salt and pepper.
  • Spread the pesto over the lamb, leaving a 1-inch border on all sides.
  • Roll up the lamb and tie with butcher's twine; season with salt and pepper.
  • Set the lamb on a rack in a large roasting pan and brush it with more olive oil.
  • Arrange the eggplant and tomato slices in a single overlapping layer around the lamb.
  • Brush the vegetables with olive oil and season well with salt and pepper.
  • Roast the lamb for 15 minutes.
  • reduce the oven temperature to 375 and roast for 30 minutes longer, or until an instant-read thermometer inserted in the thickest part of the meat registers 140 for slightly pink meat.
  • Transfer the lamb to a carving board and cover it loosely with foil; let stand for about 10 minutes.
  • Slice the lamb and serve with the vegetables.
