01 - Preheat the oven to 425°F. Pat the lamb rack dry with paper towels to ensure proper browning.
02 - Combine olive oil, minced garlic, thyme, rosemary, sea salt, and black pepper in a small bowl to create a herb paste.
03 - Rub the herb paste evenly over the entire lamb rack, coating all sides thoroughly.
04 - Heat a large ovenproof skillet over medium-high heat. Sear the lamb rack fat side down first, cooking for 2 to 3 minutes per side until a golden-brown crust forms.
05 - Transfer the skillet with the lamb rack to the preheated oven. Roast for 15 to 20 minutes for medium-rare, aiming for an internal temperature of 135°F, or adjust time to preferred doneness.
06 - Remove the lamb from the oven and loosely cover with foil. Allow it to rest for 10 minutes to retain juices.
07 - Slice the rack into individual chops. Garnish with extra thyme sprigs and a sprinkle of flaky sea salt before serving.
