Flat iron steaks on the grill make for an epic, beefy, and tender dinner at home. Given its uniform thickness and nice marbling, it’s the perfect cut for grilling. In recent years, the flat iron steak has become increasingly popular on restaurant menus across the country, and for good reason.

What is a Flat Iron Steak?

Taken from the upper portion of the top blade roast, the flat iron steak is named after its triangular shape (like a clothes iron). The bold, beefy flavor of the flat iron cut makes it the second most tender steak, right behind the filet mignon.

So, where has this steak been all your life? Well, the top blade roast was actually overlooked for years due to the tough tissue that runs through its center. Once that tissue was removed and the roast was separated into two pieces, the incredibly tender flat iron steak was born.

Now that you’ve been properly introduced, you should know this popular steak has the best of both worlds with its extra tender consistency and incredibly juicy flavor. Hand-trimmed and aged at least 28 days for a superior experience, we’re betting it’ll be your new favorite!

Using the app is simple and extremely efficient: enter the steak cut and thickness and your desired doneness, then start the cooking timer. The app will alert you when it’s time to flip and when your steak is done.

5. Rest Steaks 5-10 Minutes

Take your steaks off the grill and allow them to rest for 5-10 minutes so the juices can redistribute, ensuring every bite is juicy perfection.
