| 1 | 7–8 lb. leg of lamb, at room temperature |
| 4 cloves | garlic, medium-sized, peeled, divided |
| ¼ c | fresh breadcrumbs |
| ¼ c | finely chopped fresh rosemary |
| kosher salt and freshly ground black pepper | |
| 2 T | olive oil |
| 2 T | Dijon mustard |
Preheat the oven (with the rack positioned in the center) to 350°F.
If your butcher has not already done so, remove the excess fat from the lamb, leaving a very thin layer to protect the meat while cooking. Use the tip of a paring knife to make small incisions all over the lamb. Cut three of the garlic cloves into slivers and slip them into the incisions.
Mince the remaining garlic, then add it to a large bowl, along with the breadcrumbs, parsley, and rosemary. Toss to combine, then season with kosher salt and black pepper. Mix well. Rub the lamb all over with olive oil, then brush with the mustard. Sprinkle the bread-crumb mixture over the lamb and pat it with your hands to form a thick, even coating. Line a large roasting pan with aluminum foil, then place the lamb fat side up in the pan. Transfer to the oven and roast until a meat thermometer inserted at the thickest point registers 130°F, about 1½ hours. Remove the lamb from the oven and set it aside to rest at room temperature for 20 minutes before carving.
Serves 8-10.
