In a large bowl, combine bread crumbs, garlic, rosemary, 1 teaspoon salt and 1/4 teaspoon pepper. Toss in 2 tablespoons olive oil to moisten mixture. Set aside. Season the rack all over with salt and pepper. Heat 2 tablespoons olive oil in a large heavy oven proof skillet over high heat. Sear rack of lamb for 1 to 2 minutes on all sides. Set aside for a few minutes. Brush rack of lamb with the mustard. Roll in the bread crumb mixture until evenly coated.
For oven cooking, place the lamb in an uncovered roasting pan and cook at 165 degrees C (325 degrees F). For every 0.5 cm (inch) of thickness, allow 10 to 15 minutes of cooking time. You can allow more time for a well-done steak, cooking to an internal temperature of 76 degrees C (170 degrees F).
Grill the chops. Add the lamb chops to the grill and grill over high heat with the lid open. If you get any flareups, move the chop to a cooler part of the grill until the flames die down. After about 4 minutes, turn the chops over and cook for another 4 to 5 minutes. Lamb chops-about 1 inch thick. 1/2 teaspoon per chop of Dried rosemary. 1/2 tablespoon per chop Olive oil. Pinch per chop or to taste of Salt. Pinch per chop of Pepper. Directions. Trim the fat.
