This was my first experience with flat iron steaks but it won't be my last. Damn, that's some good cow, y'all! Very lean and beefy and tender. I brushed them with EVOO (because they're so lean), sprinkled them with salt and cracked pepper, and grilled them 4 minutes per side on a hot grill. Which was a bit too long and/or hot because they came out medium instead of medium rare, so next time I'll adjust that a bit. They were still extremely tender and flavorful, though, and the outside got nice and caramelized. I'd heard you had to marinate flat irons to get them tender, but that definitely wasn't the case with these babies!
