Product Details

Our Wagyu Flat Iron Steak is a hidden meat gem. Cut from the top blade of the Chuck, this steak is rich and marbled and surprisingly tender, thanks to our clever butcher who removes the tough fascia and trims it to be steak-ready. You read that right. This steak is ready for you. It’s waiting. What are you waiting for? Throw it on the grill or sear in a hot pan and eat it. 

Our 100% Fullblood Wagyu Flat Iron Steak is an outstanding, lesser-known cut with marvelous marbling that is perfect for the grill.

Product Details

The Flat Iron comes from the Top Blade section of the Chuck, located just under the shoulder blade. "Steak-Ready" Flat Iron means that the fascia membrane has been removed and the cut trimmed to be ready for the plate. The expected Wagyu flavor, tenderness and marbling show up well in the Flat Iron, and because of this, Wagyu Flat Iron is growing in popularity and can be found served at top restaurants across the country. Our "steak-ready" flat iron weighs approximately 1.5 pounds but can vary in size by as much as a half pound, due to the varying sizes of the muscle. Flat Iron Steaks are outstanding on the grill or skillet.  Each steak offers several servings.

Preparation Tips 

Thaw your Wagyu in the refrigerator for 24 hours. Once thawed, allow meat to reach room temperature for 30 minutes.

Grill: Heat grill to medium high. Season your steak generously with sea salt and fresh ground pepper. Cook for 6 minutes on each side. Let rest 10 minutes before digging in, tenting with foil if you'd like to preserve heat.

Seared: Heat cast iron skillet with olive oil over medium heat until very hot. Season steak generously with sea salt and fresh ground pepper. Cook for 4-5 minutes per side. Let rest for 5 minutes before slicing. 

Prep Tips

Thaw the the Wagyu flat iron steak as you see fit (see below under "Handling and Thawing" for deeper guidance.) We also suggest bringing thawed steaks to room temperature for 30 minutes or so.

We always recommend cooking Wagyu to no more than Medium Rare. But your oven might throw heat better than ours, or you might be at sea level while we're up past mile-high. So, for the love of all things holy - like your precious Wagyu - take our timing specs with a grain of proverbial salt. Use your common sense and maybe even a meat thermometer and don't take our word for gospel. 

Grill: Heat the grill to medium high. Season the steak with salt, at minimum, or anything else that floats your boat. Sear each side for a minute or two. We're looking for Maillard reaction - that's brown and crispy. Move steaks to a lower heat and cook for another couple maybe 4-5 minutes. Take off the heat and let rest for 5 minutes, if you can wait. Oven: Heat oven to 425 F. Heat a cast-iron skillet over high heat on stove, and add a pat of butter or oil. Season the steak as your heart desires. Same idea as above: sear each side for a minute or two until browned and then transfer skillet to the oven for a few minutes, maybe 4 or 5. Take out and let rest for 5 minutes. We dare you.


Loved the flavor.

Handling & Thawing

Not digging into your Wagyu right away? Place your vacuum-sealed package in your freezer upon delivery. Your meat should be good for up to 12 months in your freezer… though we doubt it will stay there that long!

Have some time? Thaw your beef in the refrigerator for up to 48 hours. This is the best way to thaw, allowing the Wagyu to retain all of its natural juices for an exceptional flavor.

Hungry sooner? Keep beef in the vacuum-sealed package and submerge in a bowl of cold water for a few hours.

Change of dinner plans? Thawed steaks still in the vacuum-sealed package can be safely refrozen as long as they have remained refrigerated and have not been thawed for longer than a day.
