Step 1

Combine the olive oil, garlic, rosemary, lemon juice, lemon zest and salt & pepper in a small bowl.

Step 2

Pour the mixture over the racks of lamb and let marinate at least 30 minutes, or up to overnight.

Step 3

When ready to grill, allow the lamb to come to room temperature (about 20-30 minutes) while you preheat your grill. Season the racks with salt and pepper.

Step 4

Prepare grill for high heat (450°F).

Step 5

Cover the bones of the lamb with foil (to prevent charring) and place on grill, fat side down. Close grill and let cook for 7 minutes, flip and cook for another 5 minutes, or until the internal temperature reaches 145°F for medium-rare (or see below).

Step 6

Remove from grill and let lamb rest 10 minutes. Cut into individual chops.
