Flat Iron Steak vs Flank Steak: What You Need to Know
Flat iron steak stands out with better marbling, tenderness, and richer flavor than flank steak—making it ideal for marinades and grilling.
Why Flat Iron Steak Stands Out
This well-marbled chuck shoulder cut has its tough gristle removed, leaving a tender, juicy steak perfect for high-heat cooking. It delivers rich beefy flavor at an affordable price.
What Makes a Marinade Work
-
Oil (olive, avocado) locks in moisture and spreads flavor.
-
Aromatics & Salt (garlic, herbs, soy sauce) boost flavor depth.
-
Sweetness (brown sugar, honey) creates caramelized browning.
Note: Marinate 2–12 hours to avoid mushy meat; a pinch of baking soda helps tenderize.
