01 - Preheat the oven to 400°F. Pat the lamb rack dry with paper towels and season generously with salt and pepper.
02 - Heat 1 tablespoon olive oil in a large ovenproof skillet over medium-high heat. Sear the lamb rack, fat side down, for 2-3 minutes, then turn and sear the other side for 1-2 minutes until browned. Remove from heat and let cool slightly.
03 - In a bowl, combine breadcrumbs, parsley, rosemary, thyme, garlic, lemon zest, and 2 tablespoons olive oil. Mix until well combined.
04 - Brush the seared lamb rack with Dijon mustard on the fat side. Press the herb breadcrumb mixture onto the mustard-coated side, ensuring an even crust.
05 - Transfer the skillet with the lamb to the oven. Roast for 18-22 minutes for medium-rare, or until an internal temperature of 135°F is reached.
06 - Remove from the oven, cover loosely with foil, and let rest for 10 minutes before slicing into individual chops. Serve immediately, garnished with extra herbs if desired.
