Preheat your oven to 450°F. Line a quarter-sheet pan with aluminum foil and place an oven-proof rack inside the pan, set the pan aside until ready to use.
Remove the lamb from the refrigerator and dry it with paper towels. Place it on a large plate and generously season it with a few pinches of Kosher salt and freshly ground black pepper.
In a small food processor, add the olive oil, freshly minced garlic, rosemary, thyme, and lemon zest. Place the top on the food processor and blend everything for about a minute until a smooth paste forms.
Then, generously smear the herb rub all over the lamb rack using your hands. Set it aside for about an hour to allow the flavors to penetrate the meat.
Lay the lamb, fat side up, on the wire rack in the prepared pan. Bake in a 450°F oven for 15 minutes.
After 15 minutes, rotate the pan to 180° in the oven and roast for another 10 minutes for medium-rare1 or 15 minutes for medium-done.
Remove the pan from the oven and allow the meat to rest for 10 minutes. Transfer the lamb rack to a cutting board and, cutting between the ribs, cut it into individual chops.
