Remove the steaks from the fridge about 30 minutes to 1 hour before cooking.
Place them on a paper towel-lined cutting board and pat them dry with paper towels.
Season well all sides of the steaks with coarse salt and set aside.
In a 12-inch cast iron skillet over medium heat, add olive oil. When the pan is near smoking, it’s a sign that it’s properly heated.
Place the steaks in the hot skillet and cook for about 3 minutes each side or until the steaks get a nice crust.
Reduce heat to medium-low, add butter and garlic. Flip the steaks again and tilt the pan to help the butter spread on the skillet.
Using a spoon, pour butter over the steaks. Flip again the steaks and check the internal temperature of the steaks. For rare is Medium rare is 135 degrees, medium = 145 degrees, medium well = 150 degrees and well done = 160 degrees.
The totally cooking time for my steak was about 8 minutes. It will depend on how you prefer your steak to be (rare, medium, medium well or well done).
Transfer to plates. Let rest 5 minutes before slicing.
