01 - Preheat oven to 400°F. Pat lamb rack dry with paper towels and season generously with salt and pepper on all sides.
02 - Heat 1 tablespoon olive oil in large ovenproof skillet over medium-high heat. Sear lamb fat side down for 2-3 minutes, turn and sear opposite side 1-2 minutes until browned. Remove from heat and cool slightly.
03 - Combine breadcrumbs, parsley, rosemary, thyme, garlic, lemon zest, and 2 tablespoons olive oil in mixing bowl. Mix thoroughly until evenly distributed.
04 - Brush seared lamb with Dijon mustard on fat side. Press herb breadcrumb mixture firmly onto mustard-coated surface, creating uniform crust.
05 - Transfer skillet to oven. Roast 18-22 minutes for medium-rare, until internal temperature reaches 135°F when measured with meat thermometer.
06 - Remove from oven, cover loosely with foil, rest 10 minutes before slicing into individual chops. Serve immediately, garnished with additional herbs if desired.
