My easy marinated pan-seared flat iron steak is beyond delicious and the perfect meaty main to serve with any of your favorite sides! Steaks are marinated in a garlicky red wine marinade that tenderizes the meat and infuses it with incredible flavor!
Combine all the marinade ingredients into a mixing bowl.
½ cup dry red wine, ¼ cup olive oil, 1 tablespoon lemon juice, ½ tablespoon minced garlic, ½ tablespoon onion powder, 1 teaspoon sea salt, 1 teaspoon ground black pepper
Pour the marinade into a Ziploc bag.
Add the flat iron steaks into the bag, press the air out and seal the bag.
1 lbs flat iron steak
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.
½ tablespoon olive oil
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.)
each, salt & pepper
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!
