01 - Set the oven temperature to 400°F.
02 - Pat the rack of lamb dry with paper towels. Season generously with salt and black pepper on all sides.
03 - Heat 1 tablespoon olive oil in a large ovenproof skillet over medium-high heat. Place the lamb fat side down and sear for 2 to 3 minutes until browned. Turn and sear the opposite side for 1 to 2 minutes. Remove from heat.
04 - Combine Dijon mustard, remaining olive oil, minced garlic, rosemary, parsley, thyme, and lemon zest in a small bowl. Mix thoroughly.
05 - Brush the seared lamb evenly with the mustard-herb blend, pressing gently to ensure adhesion.
06 - Transfer the skillet with lamb to the preheated oven. Roast for 15 to 20 minutes for medium-rare doneness (internal temperature 130–135°F), or adjust cooking time to preferred level.
07 - Remove from oven. Tent loosely with foil and allow the meat to rest for 10 minutes.
08 - Cut the rack into individual chops. Garnish with lemon wedges and additional herbs as desired. Serve immediately.
