Perfect, Easy Ribeye Steak that is butter basted in a cast iron skillet in the oven with Rosemary. A Perfect error-proof medium rare in 20 minutes including resting time.
Sear the steaks on high heat for 30 seconds on each side.
Put the pan with the steaks into the oven for 4-5 minutes (if you'd like you can flip them halfway through - I don't and you can see how mine have cooked through.)
Rest for five minutes before serving.
