I sear my rack of lamb over high heat for a crisp herb crust, then finish it over lower heat for a tender pink interior. My pea-and-mint pesto brightens the whole meal.
Preheat your grill to high heat - about 600 degrees Fahrenheit. In a small bowl, mix the olive oil, parsley, rosemary, thyme, Dijon, salt, pepper, and garlic.
3 tablespoons olive oil, 1 tablespoon EACH: finely minced parsley, rosemary, and thyme, 1 teaspoon EACH: sea salt and pepper, 3 cloves garlic, 2 teaspoons Dijon mustard
Rub this mix all over the meat on both racks of lamb. Let this wet rub marinate the meat while you make the pesto.
2 racks of lamb
Combine all the pesto ingredients together in a small blender or food processor and blend until mostly smooth.
1 cup frozen peas, ¼ cup fresh mint leaves, ¼ cup olive oil, 1 tablespoon lemon juice, ¼ teaspoon sea salt, ¼ cup grated parmesan cheese
Sear the meat, fat side down, until it is well browned, about 5 minutes.
Turn the heat down to medium (about 400 degrees Fahrenheit), flip the lamb racks over, and prop them up so the bones rest against each other. Continue cooking for another 15 minutes for a small rack or 25 minutes for a large rack (see notes), until the internal temperature is 125 degrees Fahrenheit.
Remove the lamb from the grill and let it rest for 10 minutes. Cut the rack into 2-bone pieces and serve it with the mint pesto on the side.
Notes
The size of a rack of lamb can vary between a small 1-pound rack and a large 2-pound rack.
