What is Flat Iron Steak?

Here is a brief but information-packed video overview of the cut, including butchering and cooking:

In brief, this another one of those steaks whereby the name gives us no clue as to what it is or where it comes from on the steer.

The name comes from its similar appearance to an old-fashioned flat iron that was heated on an open fire and used for ironing clothes. Nothing to do with cooking steak.

It is a thick cut that is uniform and rectangular in shape, with an average 8oz cut and around 1 inch thick, making it one of the most popular steaks for grilling. With its uniform thickness, it cooks evenly and quickly, making it a joy to slap on the grill.

Where Does Flat Iron Steak Come from on the Cow?

It comes from the chuck primal, which is right up front by the shoulder.

Originally attached to the Top Blade roast, this part of the animal was thought to be a tough cut that needed slow cooking.

That is until it was discovered that by removing the central fatty connective tissue, you’re left with two distinctly different cuts of meat:

  1. The Top Blade steak which is tough
  2. The Flat Iron steak that is full of marbling for flavor and tenderness.

The appearance is similar to the Ribeye with its extensive marbling, a term that refers to the thin white strips of fat that run through the meat, and it is these intramuscular fat ribbons that give it an intense flavor.

Other Names for the Flat Iron Steak

There are only a couple of other names it’s known by in various places for differing reasons.

Here are a few alternatives name that you may recognize:

  • Butler’s steak, so-called in the UK as it was the cheaper cut of meat that in-house waiting staff, also known as butlers, would get if they were lucky.
  • Oyster Blade steak, as commonly referred to as in Australia and New Zealand. A cross between the standard cut it comes from and a reference to the fact it is found hidden within the shoulder blade and removed.

If your butcher still isn’t quite sure, just use the recognized butcher’s ID number to get the correct cut: IMPS/NAMP — 1114D PSO 1, UPC–1166.

Whichever name you know it by, you can rest assured that this steak is sure to please your guests!

Flavor, Texture, Fat Content and Tenderness

The Flat Iron has become popular for two main reasons. Its extensive marbling gives it plenty of flavor, and it’s tenderness.

The tenderness is a result of it being located towards the top of the shoulder, where it gets less exercise than the rest of the shoulder muscles.

There is no fat cap on it traditionally. Still, some butchers do now present it with some fat attached to give it extra flavor when cooking.

Typical Uses

As a popular cut being served more and more, the Flat Iron is typically used as a stand-alone cut, but coming from a slow-cooking heritage, it can be used in any recipe that calls for beef.

From a good butcher, it will come ready to place straight on the grill or smoker, needing just a simple seasoning with oil and salt in preparation to cook it.

If you do intend to smoke it, you could try smoking the whole Top Blade roast and then removing the Flat Iron steaks after it has slowed cooked, and the result is a delicious cut that will always impress.

How to Cook Flat Iron Steak on a Grill or Smoker

It is best cooked on a hot grill or hob in a sizzling hot pan but take note reader, do not use a griddle.

We want the meat to cook in its own fat from the marbling so that it retains all the flavor. A griddle drains the fat away from the meat, which means flavor and juiciness is compromised, and this is a meat crime no one should commit!

Here is our simple guide to cooking your Flat Iron steak:

  1. Pat the steaks dry and bring to room temperature.
  2. Heat your grill to maximum heat, anywhere from 450-600f grill dependent.
  3. Season with oil and salt and place them onto the grill.
  4. Following our guide on how long to grill a steak, cook until internal temperature hits 130F for medium-rare, being careful not to overcook it as it will render it dry and flavorless.
  5. Remove from the grill, it will continue to cook for a few minutes after until a final 135F. Add a knob of butter and tent in tin foil to retain heat while resting.
  6. Allow to rest for at least 10 minutes.
  7. Slice against the grain and enjoy.
