Pat the steaks dry and season both sides with salt and pepper. Let them sit at room temperature for 30 minutes.
Heat a heavy pan over medium-high for 4 minutes. Add the oil and heat until it shimmers and looks thin and shiny, 1 to 2 minutes.
Add the steaks. You should hear a strong sizzle right away. Sear 2 to 4 minutes on the first side, until well browned and easy to lift.
Flip the steaks and reduce the heat to low. Add the butter and garlic. Spoon the foaming butter over the steaks for 2 to 6 minutes, until they reach 130 degrees F for medium rare.
Move the steaks to a plate. Pour the garlic butter into a small dish right away to stop the cooking. Rest 5 minutes, then spoon the butter over to serve.

Notes
Doneness: Pull the steak at 130 degrees F for medium rare. The temperature rises a few degrees while it rests.Pan: Use cast iron or stainless steel for the best crust. Avoid nonstick.Garlic: Add it only after you flip and lower the heat so it does not burn.
