We love lamb and I normally always get it at the local butcher. A few of our friends raved about the lamb at Costco so we decided to give it a try. OMG we were very impressed by the quality and flavor of the lamb. We will defiantly get it again!
Add mint, parsley, basil, nuts, cheese, lemon juice, garlic, salt and pepper in a food processor. Pulse until the herbs are finely chopped. With the machine running, gradually blend in 1/3 cup of EVOO until the mixture is smooth and creamy.
Preheat the oven to 400 degrees F.
Season the lamb racks with salt and pepper. Heat the remaining 2 tablespoons oil and butter in a grill pan or cast iron pan over high heat. Place 1 lamb rack in the skillet and cook just until brown, about 3 minutes per side. Transfer the lamb rack meat side up on a roasting pan. Add second lamb in the hot pan and repeat process.
Roast the lamb until cooked to desired doneness, about 20-23 minutes for medium-rare. Transfer the lamb racks to a wood board. Let rest for 10 minutes. Cut the lamb between the bones into single chops.
Serve with the mint and parsley pesto!
