Pro Tips
- Flat iron is the second most tender cut after the tenderloin — seriously underrated.
- Don’t cook past medium — it’s got great marbling but toughens quickly when overdone.
- Slice thin, against the grain, for the best texture.
- A chimichurri sauce is the perfect match for flat iron.
Resting Time
Rest for 5 minutes after removing from the BBQ. This allows juices to redistribute for a juicier result.
