Season both sides of the steak with salt and pepper for about 10-15 minutes.

Heat a pan and add a little olive oil, spreading it evenly. Then, sear the steak for 2-2.5 minutes on each side, depending on your preference (remember not to move the steak). Sear both sides until cooked, then add a little unsalted butter, garlic (and rosemary if available), and drizzle over the steak before removing it to a plate (Remember not to cut the steak immediately, as cutting it too soon can cause the juices to run out).

Serve the steak with boiled potatoes and asparagus, along with a bit of black pepper sauce. Adding a glass of red wine would be perfect.
