Bring steak to room temperature by pulling it out of the fridge at least 1 hour before cooking.
Preheat oven to 375℉. Heat cast iron pan with a small amount of oil to a medium high heat (until the pan is smoking.
Generously season steak on all sides with salt and pepper. Cook on first side for 7 minutes then add butter, garlic and herbs to the pan. Flip the steak and baste with butter for 60 seconds. Place steak into preheated oven and finish cooking for 5 minutes.
Remove from the oven and let the steak rest for 5-10 minutes. Slice rested steak against the grain, top with a finishing butter (if using) and serve.
Notes
Cooking times will vary based on the steak’s thickness and your preferred doneness (medium-rare, medium, well done) - use the chart above to determine the cooking times for each side for your steaks.
