Step 1

Rub the steak with the salt, pepper, and mustard. Heat a cast iron skillet over medium-high heat and melt your butter in the pan. Add the steak and cook for 6-7 minutes on each side (6 minutes for medium-rare, 7 minutes for medium, and let's not cook it for longer than that, shall we?), making sure that there is a nice bit of black crust before turning it over.

Step 2

After cooking on each side, remove the pan from the heat and cover with foil. Allow the steak to rest for 8-10 minutes. If you skip this, all of the juices will leak out when the steak is sliced and you will lose a lot of its flavor. When ready, slice, drizzle with garlic butter (recipe below), and serve.

Step 3

Melt your butter in a pan or in the microwave, then add in the minced garlic and herbs. Stir to combine, then allow to sit for 5 minutes or so, until the flavors have melded together a bit. Drizzle over the steak and enjoy.
