Set out steaks a couple of hours before to let them come to room temperature.
Preheat oven to 400°F.
Rub both sides of each steak with olive oil. Season both sides with salt and pepper.
Heat a cast iron skillet over medium-high heat. Once it is very hot, add in the steaks. Sear for 1-2 minutes or until you get a nice crust.
Flip and cook for another 1-2 minutes on the second side.
Remove from the heat and top each steak with a tablespoon of butter. Add the thyme to the pan.
Bake for 10-15 minutes, until desired temperature is achieved.
Let the steaks rest for 5-10 minutes before serving with more butter.
