The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions, to ensure that you have all the ingredients and equipment required and understand the steps and timings involved.

Flat iron steak is a more affordable cut of beef than tenderloin, but nearly as tender.

Because of the marbling of flat iron steak, it is known for its rich, beefy flavor, which is great on its own, but as you’ll see in this flat iron steak recipe, it benefits from a marinade.

Flat iron is not as well known as flank or skirt steak, and you may confuse them, but flat iron steak is cut from the shoulder of the cow, while flank and skirt come from the belly area.

Because of this, flat iron steak is best cooked to just medium-rare and no more

In the UK, you will find this cut called butler steak, and it is known as oyster blade steak in New Zealand and Australia.

Book steak, shoulder top blade steak, and petite steak are just a few other cuts found in various regions around the world that seem to resemble the flat iron steak.

And if you’re wondering where this steak gets it’s name from, it’s allegedly because it looks like an old-fashioned metal flat iron!
