What Flat Iron Is

Flat iron is a cut from the shoulder, taken from the top blade portion of the chuck. It is valued for reliable marbling and tenderness once the central connective seam is removed.

In Wagyu, flat iron offers a rich, savory bite with more structure than ribeye, making it a practical choice for buyers who want balance.

Where It Comes From

Flat iron comes from the shoulder area of the animal, within the chuck primal. It sits above the shoulder blade and is part of the top blade muscle.

When the seam of connective tissue is removed, the muscle can be cut into flat iron steaks or left as a small roast.

Marbling and Texture

Flat iron shows consistent marbling through a slightly coarser grain than ribeye. At higher BMS levels, the fat melts readily and increases richness, while the muscle keeps a defined chew.

How to Cook Flat Iron

Sear over high heat and finish to medium-rare, then rest to keep the cut tender and juicy.

Common Flat Iron Terms

  • Flat iron steak: the most common retail name for the trimmed top blade muscle.
  • Top blade steak: an older name that may include more connective tissue.
  • Shoulder top blade: the primal muscle flat iron is cut from.
  • Flat iron roast: a larger cut meant for slicing after cooking.
