Marinade Instructions
Combine all the marinade ingredients into a mixing bowl.
Pour the marinade into a Ziploc bag.
Add the flat iron steaks into the bag, press the air out and seal the bag.
Marinate in the refrigerator for at least 4 hours.
Pan Sear The Flat Iron Steaks
Remove bagged steak from the refrigerator, then remove the steaks from the marinade, using a paper towel dab to remove excess marinade, and allow to come to room temperature.
Heat a large skillet or cast iron pan to medium high. Add the olive oil to the pan.
Get the pan very hot, the oil should be shimmering.
Sprinkle the steaks with salt and pepper. Add the steaks to your heated pan and cook for 4-6 minutes, turn steaks over for another 3-5 minutes. (Use an instant-read temperature probe to determine doneness.)
When steaks are 2 minutes away from being done add the butter to the pan. Spoon the butter over the steaks.
Remove steaks from pan and allow to rest 5 minutes before serving, enjoy!
