Cook Time & Temperature for Steak
Flat iron steak is very versatile, but it tastes best cooked to medium-rare or 135 F (on an instant-read thermometer).
Flat iron steak is great for grilling as it can be cooked quickly and is usually a consistent thickness. A pound of flat iron steak can be cooked in 8 to 10 minutes.
How to Prep Flat Iron Steak
Flat iron steak should be cooked three to five days after you purchase it.
Keep it wrapped while it’s in the refrigerator, but pull it out and unwrap it about 30 minutes to an hour before you grill it.
Allow it to come to room temperature on the counter, and sprinkle it with some kosher salt.

Flat iron steak is also called top blade steak, top blade filet, and shoulder top blade steak.
