1.  Using paper towels, pat both sides of the steak dry; season generously with 1 1/4 teaspoons salt and 1/2 teaspoon pepper.  2.  Heat a medium cast iron skillet over medium high heat until very hot, about 1-2 minutes; add canola oil.
3.  Place the steak in the middle of the skillet and cook, turning every 2-3 minutes, until a dark crust has formed on both sides, about 12-14 minutes.
4.  Reduce heat to medium low. Push steak to one side of the skillet; add butter, garlic, thyme and rosemary to opposite side of the skillet, tilting the skillet towards the butter and cooking until butter is foaming, about 30 seconds to 1 minute.
5.  Working carefully, spoon butter over steak for 1-2 minutes, turning over once, until it reaches an internal temperature of 120 degrees F for medium rare, or until desired doneness. Let rest 15 minutes before slicing.
6.  Serve immediately
