Flat Iron Vs Flank: The Difference Between These Two Steak Cuts - Tasting Table
Briefly

Flat iron steak, sourced from the cow's shoulder, offers more marbling and tenderness compared to flank steak, making it a richer and more affordable option.
Flank steak, coming from below the cow's loin, is leaner but thicker and firmer than flat iron, making it ideal for marination and diverse recipes.
