One hour before dinner is to be served, sprinkle steaks with salt and pepper to taste, place on a rimmed platter, cover, and set aside to bring to room temperature.

Blend cheese and parsley in small bowl to combine. 

Preheat broiler. In a heavy skillet big enough to accommodate both steaks, melt butter over medium-high heat. Add steaks to skillet and cook to desired doneness, about 5 minutes per side for medium-rare. Top steaks with cheese mixture and broil until cheese browns, about two minutes. Allow to rest for a few minutes before serving; drizzle any pan juices onto serving plates.
