Instructions
 

For the steak:

  • Mix all ingredients except for the flank steak in a gallon-sized Ziploc bag. Add flank steak, and allow the steak to marinate in the refrigerator for a minimum of 4 hours and up to overnight.
  • Preheat oven to 400°. 
  • Heat a cast-iron skillet over high heat until a few drops of water sprinkled in the skillet “dance” and evaporate.
  • Add meat and sear for 3-5 minutes on each side, or until a deep brown color is achieved.
  • Place the skillet in the oven and check meat with a meat thermometer every 5 minutes until desired cook is reached.
  • Let meat rest for 10 minutes, tented with foil, and slice against the grain. Serve with a pat of cowboy butter.

For the cowboy butter:

  • Mix all ingredients together and place on a sheet of plastic wrap.
  • Form into a log shape, roll up in the plastic wrap, and twist the ends. Tuck ends underneath the roll of butter and refrigerate.
  • Unwrap and slice to serve.
