Grilled Flat Iron Steak

20 mins
4 hrs
10 mins

Sweet, caramelized honey and tangy lime juice with a bite of jalapeno spice give this Grilled Flat Iron Steak a robustly complex flavor profile. The flat iron cut is well-marbled for a rich, true beef experience and marinated for meltingly tender flavor in every bite. Take the spice level up with more peppers and seeds or take it down with less.

We made this recipe on the Performance Series 4-Burner Gas Grill, but you can make it on your grill.
