How long does it take to cook a sirloin steak in a cast iron skillet?
Sear the steak for 9 minutes on one side, flip and sear 7 minutes on the other. Spoon the butter mixture over the steaks and cook an additional 30 seconds per side. Remove the steak from the pan when the internal temp reaches 155 degrees and allow the steak to rest for 5-10 minutes.
