  • 1 1 - 1.5 pound Flat Iron Steak Try Snake River Farms Flat Iron
  • 1 tablespoon extra virgin olive oil
  • 1 tablespoon SPG Rub


  • Prepare grill for direct grilling, using lump charcoal targeting 500 degrees Fahrenheit directly under the flat iron.
  • Apply olive oil to steak, then generously season the steak with the beef rub.
  • Place the steak on the grill over direct heat. You should hear it sizzle as soon as it hits the grate. Grill over direct heat for 3 - 4 minutes or until you see char marks. Flip the steak over and grill the other side for additional 3 - 4 minutes or until char marks form.
  • Remove from the grill when the internal temperature of the steak reaches 125 degrees F for rare using an instant read thermometer.
  • Let the steak rest for 10 minutes to allow for carry over cooking, and then slice in pencil thin slices. Serve alone or with our Jalapeño Parsley Chimichurri Sauce.


A note about times: Every grill will run a different temperature. If you like your steak cooked to a higher temperature, then flip every 3 minutes to keep it cooking evenly on both sides until it reaches your desired internal temperature.
