Bring to room temp: Take the steak out of the fridge 30 minutes prior to bring to room temperature.
Dry steaks: Pat dry with paper towels.
Heat skillet: Heat oil in a heavy based skillet over high heat until it is very hot β you should see smoke!
Season: Sprinkle each side of the steak generously with salt and pepper, then immediately place in the skillet.
Sear Side 1: Cook for 2 β 2.5 minutes until you get a great crust, then turn.
Garlic Butter: Leave for 1 minute, then push steaks to one side and toss in butter, garlic and thyme. BE CAREFUL β the thyme will sputter!
Baste: As soon as the butter is melted, continuously spoon the butter over the steak until itβs cooked to your liking β 2 minutes in total for the 2nd side for medium rare (52C/125F, chart below for other doneness temps)
Basting also renders fat on the side of the steak β use tongs to sear the edges at the end if you want it browned more.
Rest: Transfer steak to a plate and cover loosely with foil, rest for 5 to 10 minutes.
Serve steak with a bit of the butter from the skillet drizzled on top.
