01 - Preheat the oven to 400°F.
02 - Pat the rack of lamb dry and season generously with salt and freshly ground black pepper.
03 - Heat 1 tablespoon olive oil in a large ovenproof skillet over medium-high heat. Sear the lamb, fat side down first, until browned on all sides, approximately 2 to 3 minutes per side. Remove from heat and set aside.
04 - In a small bowl, combine chopped parsley, rosemary, thyme, minced garlic, fresh breadcrumbs, grated Parmesan cheese, and 2 tablespoons olive oil until thoroughly blended.
05 - Brush the seared lamb evenly with Dijon mustard. Press the herb mixture onto the mustard-coated lamb, covering the top and sides.
06 - Place the lamb back in the skillet or on a baking sheet. Roast in the preheated oven for 18 to 22 minutes until medium-rare, or until an internal temperature of 135°F is reached.
07 - Remove the lamb from the oven, loosely cover with foil, and let rest for 10 minutes before slicing into chops.
