i know a lot of people like to grill steak, but the good old cast iron pan i think makes steak extra special.
heat the oil and butter over medium high heat.
make sure steaks are at room temperature. never put a cold steak in a hot pan. pat the steak dry then season on both sides with a good amount of salt and pepper.
add the garlic and rosemary to your pan.
place your steaks in the pan, your cook time will depend on how rare you like your steak and the thickness of the steak. i like mine medium rare and they were not terribly thick so i went about two and
