Flat Iron vs Hanger — What's the Difference?
Quick Answer
Side-by-side
| flat iron | hanger | |
|---|---|---|
| Primal | chuck | plate |
| Muscle / location | Infraspinatus muscle, top blade of the shoulder clod | Hangs from the diaphragm, between the last rib and the loin |
| Character | The second most tender muscle on the entire animal, after the tenderloin. A flat, rectangular steak extracted from the top blade by splitting it along the central connective tissue. Uniform thickness makes it ideal for grilling. Also known as butler's steak in the UK. | Also called hanging tender or butcher's steak. A thick, V-shaped muscle that 'hangs' from the diaphragm — only one per animal. Extremely flavorful with a coarse grain. Distinct from skirt steak, which is the diaphragm muscle itself. |
Key differences
- Different primals: chuck vs plate.
- Texture and slicing: compare fibrous, grain-heavy cuts vs more tender steak-style muscles based on each cut’s description.
- Retail naming diverges by country—always map through a canonical cut when translating menus or labels.
When to use each
Flat Iron
Pick Flat Iron when you want its specific marbling/texture profile: The second most tender muscle on the entire animal, after the tenderloin. A flat, rectangular steak extracted from the top blade by splitting it along the central connective tissue. Uniform thickness makes it ideal for grilling. Also known as butler's steak in the UK.
Hanger
Pick Hanger when its primal/muscle traits fit the dish: Also called hanging tender or butcher's steak. A thick, V-shaped muscle that 'hangs' from the diaphragm — only one per animal. Extremely flavorful with a coarse grain. Distinct from skirt steak, which is the diaphragm muscle itself.
Flat Iron and Hanger are different canonical muscles/primals: Flat Iron is chuck (Infraspinatus muscle, top blade of the shoulder clod); Hanger is plate (Hangs from the diaphragm, between the last rib and the loin).
Choose based on tenderness, marbling, grain direction, and how you plan to cook (sear vs braise vs slice thin).
