Before we dive into the cooking process, let’s talk about what Wagyu flat iron steak actually is.

Wagyu beef comes from Japanese cattle breeds that are known for their high levels of marbling, resulting in a slice of more flavorful and tender meat.

The flat iron steak comes from the shoulder of the cow and is a relatively new cut that has gained popularity recently due to its great flavor and affordable price point in comparison to the more expensive cuts.

When you combine the two, you get a delicious and luxurious cut of beef that’s a must-try for any steak lover.

Selecting and Preparing Your Wagyu Flat Iron Steak

To start, you’ll want to find a high-quality Wagyu flat iron steak. Look for one that has even marbling throughout and is a deep red color.

You can typically find Wagyu beef at specialty butcher shops or online.

Before cooking your steak, it’s important to let it come to room temperature. This allows for even cooking throughout the meat.

Season your steak generously with salt and pepper and let it sit for about 30 minutes while you prepare your cooking equipment.

How To Cook Wagyu Flat Iron Steak

When cooking your Wagyu flat iron steak, you can use a few different methods.

Here are some of the most popular ways I recommend:

Grilling

Grilling is a popular method for cooking steaks and works well for Wagyu flat iron.

Preheat your grill to high heat and place your steak on the hot grates.

Cook for 2-3 minutes on each side, then move the steak to a cooler part of the grill to finish cooking.

Let the steak rest for a few minutes before slicing and serving.

Pan-Searing

Pan-searing is another great option for cooking Wagyu flat iron.

Heat a cast-iron skillet over high heat and add a little oil to the pan.

Place your steak in the pan and cook for 2-3 minutes on each side until a crust forms.

Finish the steak in the oven at 400°F for about 5-6 minutes until it reaches your desired level of doneness.

Let it rest for a few minutes before serving.

Sous Vide

Sous vide cooking is a more advanced method for cooking steak, but it results in a perfectly cooked piece of meat every time.

Season your steak and vacuum-seal it in a bag.

Cook it in a water bath at 130°F for 2-3 hours, then sear it in a hot pan for a few seconds on each side to form a crust.

Serving Your Wagyu Flat Iron Steak

Once your steak is cooked to perfection, it’s time to serve it up.

I recommend slicing it into thin strips against the grain to ensure maximum tenderness.

Pair it with your favorite side dishes, such as roasted vegetables, pomme frites, or garlic mashed potatoes, and enjoy!
