- Preheat oven to 375 degrees F.  
- Turn heat on medium high  heat and get cast iron pan very hot, prior to adding oil.  
- Add oil and wait about 1 minute.  Add steaks. Steaks must be dry and cold.  
- Use a grill press if you have one. The press keeps the steak on the pan evenly.  
- Sear for about 3 minutes.  The steak should easily move. If not give it another minute. 
- Test with an instant read thermometer which will help gage how much time you need in oven. You will want the final temperature to be 130 degrees F.   
- Once seared, turn over and place in oven.  Cook to 130 degrees F. for medium rare. 
- Season with salt and pepper. Allow to rest for 7 minutes, before cutting.
