Ingredients

  • 3 clovegarlic cloves, minced
  • 3 sprigfresh rosemary sprigs, leaves stripped and chopped
  • 2 tbspextra-virgin olive oil
  • 1 tbspDijon mustard
  • ½ tbspkosher salt
  • 1 tspfreshly ground black pepper
  • 1 rackfrenched lamb rack (about 2 pounds)
  • flaky finishing salt(optional)

Instructions

  1. Pat the lamb rack completely dry, then massage the minced garlic, chopped rosemary, salt, and pepper into every surface. Slide it into a plastic bag with the olive oil, working the oil around to coat thoroughly. Seal tight, pressing out air, then marinate overnight in the fridge or 1.5-2 hours at room temperature.
  2. Pull the lamb from the refrigerator 1.5-2 hours before cooking — cold meat will cook unevenly. This step is crucial for achieving consistent doneness from edge to center.
  3. Position your oven rack in the center and preheat to 450°F. The high initial temperature will be key to developing that coveted crust.
  4. Score the fat cap with shallow cuts about 1 inch apart — this helps render the fat and prevents the meat from curling. Season again with salt and pepper, then place fat-side up on a foil-lined roasting pan. Wrap the exposed rib bones with foil to prevent burning.
  5. Slide into the 450°F oven for exactly 10 minutes. You'll hear it sizzle and see the surface develop a rich golden-brown color — that's the Maillard reaction working its magic.

  6. Drop the temperature to 300°F and continue cooking 10-20 minutes more. For rare, pull it at 125°F internal temperature; for medium-rare, wait until 135°F. Use an instant-read thermometer inserted into the thickest part of the meat.
  7. Transfer to a cutting board, tent loosely with foil, and let rest for 15 minutes. The temperature will continue rising slightly while the juices redistribute throughout the meat. Slice between the bones and finish with flaky salt if desired.
