What is Flank Steak?

What is flank steak, and why is it so popular in the United States? You may have heard of this medium-rare specialty steak by one of its other names—London Broil.

What is Flank Steak, Exactly?

Knowing your beef cuts is essential if you want to fully develop your meat lover’s palette, but what is flank steak? Here is some surprising news about this steak: it is not actually “meat,” it is muscle. As one of the most flavorful steaks available, flank steak is on the tough side because muscle works hard.

If you know how to cook it, flank steak makes for a delicious meal. The right preparation is all this meat needs to provide a perfect steak cooked in a single slab of flavor. The flank is about an inch thick on one end and tapers down to about half an inch on the other.

Flank steak is in the lean steak category. You will typically see muscle fibers on one side of the steak, and its deep red tinge makes it easy to recognize. When shopping, deep red indicates freshness (brownish hues show longer exposure to oxygen).
