The flat Iron steak – also referred to as the ‘top blade steak’ – is a thinly cut steak that comes from the hard-working shoulder (“chuck”) of a cow. Typically containing a high amount of intermuscular fat (or, ‘marbling’), the flat iron steak has skyrocketed in popularity in the UK due to it’s premium taste yet affordable price! It’s so tasty in fact that it’s becoming known as the nation’s affordable alternative to the tenderloin or fillet! It’s taste profile is very ‘beefy’, however, it’s known to be very versatile; matching a luxurious marinade on one day whilst a simple coating of salt on another!
Buy Sustainable Flat Iron SteakThe flat iron steak is named so because it supposedly looks like an old-fashioned metal flat iron. The happymeat.uk team isn’t sure why though, as it’s rectangular in shape? More broadly, the story goes that the flat iron steak was originally part of the top blade roast. Top blade roasts have a very tough bit of connective tissue that runs through their middle. At one point however, butchers decided that they would remove the tough part in the middle, making 2 pieces of meat — one of them being (yes, you guessed it) our beloved flat iron!
To ensure the highest quality at an affordable price, our artisan butchers strongly recommend buying flat iron steaks that come from cows that have been grass fed. Flat Iron steaks coming from grass fed cows are considerably healthier (having a higher % of antioxidants, vitamin A and omega 3 fatty acids), and more premium in taste. The difference in taste can be matched to the difference between an organic and GMO onion. That’s big.
Spotting a grass fed flat iron steak is easy: just look for rich, dark red meat color matched with fat or ‘marbling’ that is orange (yes, that’s right, not pale white) in tone. Read more about why the fat is this color in our complete guide to grass fed beef.
