Flank steak and flat iron are two popular cuts of beef that are used in a variety of dishes. While they share some similarities, there are also some key differences between the two.

One question that often comes up is whether or not you can substitute flank steak for flat iron (and vice versa). In this article, we’ll take a closer look at these two cuts of beef and explore whether or not they can be used interchangeably.

What is Flank Steak?

Flank steak is a long, thin cut of beef that comes from the belly of the cow. It’s known for its rich flavor and texture, but it can be tough if it’s not cooked properly.

Flank steak is best when it’s marinated before cooking and then cooked quickly over high heat (such as on a grill). This helps to tenderize the meat and bring out its delicious flavor.

What is Flat Iron?

Flat iron steak, also known as top blade steak, comes from the shoulder of the cow. It’s a relatively new cut of beef (it was only discovered in the early 2000s), but it has quickly become popular due to its tenderness and rich flavor. Flat iron steak is best when it’s cooked quickly over high heat (such as on a grill or in a hot skillet).

Can You Substitute Flank Steak for Flat Iron?

The short answer is no, you can’t substitute flank steak for flat iron (or vice versa) in all cases. While these two cuts of beef share some similarities, they also have some key differences that make them better suited for certain dishes.

For example, if you’re making fajitas or stir-fry, flank steak is a better choice because it’s thin and cooks quickly over high heat. Flat iron steak, on the other hand, is better suited for dishes where it can be slow-cooked (such as in a stew or braise) or quickly seared over high heat.
