Let the steaks rest at room temperature for around 30 minutes so they will cook more evenly. Pat the steaks dry with paper towels, then season generously with Kosher salt and freshly ground black pepper.
Place a 12-inch cast-iron skillet over high heat and let it preheat until it just begins to smoke.
Add a tablespoon of oil to the pan, then add the steaks. Let them cook undisturbed for around 3 to 4 minutes. Flip the steaks and cook for another 3-4 minutes.
Add 2 tablespoons of butter and a few sprigs of herbs. Tilt the pan slightly and use a spoon to baste the steaks with the melted butter for 1-2 minutes. Use an instant-read thermometer to check the internal temperature and continue cooking until it reaches 125-130°F for medium-rare or until it reaches your desired doneness.
Transfer the steaks to a plate and tent with foil. Let them rest for 5-10 minutes before serving.
