Bring your steaks to room temperature by setting out of the fridge about 30 minutes before preheating the oven.
Place your cast iron skillet in a cold oven and preheat it to the highest temperature. My oven goes to 550 degrees.
Season your steaks to your liking. I like to use Montreal Steak seasoning.
When the oven and your skillet reach temperature, remove the skillet from the oven and melt two tablespoons of butter in the skillet.
Add the steaks, seasoned side down and place the skillet into the hot oven.
Set the timer for three minutes.
Flip the steaks and cook for three minutes more.
Remove the skillet and test your steaks for desired doneness by using a meat thermometer. Return the steaks to the oven for one minute increments until the desired temperature is reached.
Allow the steaks to rest at least ten minutes before serving.
