Mix first 4 ingredients and 1 tablespoon olive oil in large bowl. Add lamb; turn to coat. Let marinate at room temperature at least 30 minutes and up to 1 hour.
Preheat oven to 400°F. Heat remaining 1 tablespoon olive oil in heavy large ovenproof skillet over high heat. Add lamb; cook until browned, about 3 minutes per side. Transfer skillet to oven and roast lamb chops to desired doneness, about 10 minutes for medium-rare. Transfer lamb to platter, cover, and let rest 5 minutes.
