What is flat iron steak?
If you've never made flat iron steak, you may be wondering what this cut of meat is! Flat iron steak is taken from the upper portion of the top blade roast. The flat iron (it supposedly got it's name because it looks like an old-fashioned metal flat iron) is uniform in thickness and rectangular in shape. This makes it perfect for grilling because it's all the same thickness.
It also has some great marbling (see above) which means it’s got a great rich beefy flavor. Flat iron steaks are also quite affordable when comparing to other cuts of beef like a good filet or rib-eye. So this penny pincher is ALL about that!
Is flat iron steak tender?
Oh yeah!! You might be scared that this cut of beef might be tough and I don't blame you. As long as it's cooked correctly it's incredibly tender. ❤️
How should a flat iron steak be cooked?
I think the best way to cook a flat iron steak is on the grill, but I've also had great success placing it under a broiler for about 10 minutes too! You'll just want to let it soak in a flavorful marinade before cooking. This really enhances the flavor and ensures a perfect steak every time. 🙂
How do you grill a flat iron steak?
This steak is very easy to grill. Marinate the steak, then grill it to medium-rare or medium. Let stand for 5-6 minutes, then slice it against the grain in thin strips. Couldn't be any simpler and really a great bang for your buck!
Don't confuse flat iron steak with flank steak. 🙂
What's the difference between flat iron and flank steak?
I get asked this a lot since getting into the menu planning business so here ya go!
A flat iron steak is cut from the shoulder area of the cow whereas a flank steak is cut from the belly muscle. Both steaks are extremely flavorful and tender (when seasoned correctly and not cooked above medium), but the flank steak is a bit leaner than the flat iron.
(This diagram might help. You'll find the flat iron steak located in the highlighted yellow section.)
Now that you're well versed with where the flat iron steak comes from and all the things, let's get to this recipe! Whew! I mean, look at this beauty – I can't wait!
First you'll want to whisk all those marinade ingredients together.
Get that steak to marinating and let it do it's thing for at least 30 minutes.
Get your grill ready while you let the steak come to room temperature.
This is also a good time to mix the butter, cheese, green onion and pepper together to make the gourmet butter. Yum!
Place that baby on the grill (preheated to medium-high) for 6-8 minutes each side. If you can handle it being on the pink side it really is more tender this way. 🙂
Patience is a virtue right!! You'll need some while you let the steak rest for about 10 minutes before slicing across the grain to serve.
Give it a good dollop of gourmet butter and the anticipation will just about do you in, ha!!
Here are a few great side dish ideas to go with this Flat Iron Steak recipe.
I like to toss some fresh asparagus with olive oil and pop on the grill. Just turn them every few minutes and they cook fast. Sprinkle with kosher salt and they are super yummy!
I do corn on the cob on the grill in a similar fashion. Both of these side dishes can be grilled at the same time the steak is grilling and are a perfect compliment!
I also think my One Dish Corn Casserole would be pretty amazing alongside this flat iron steak as well.
Baked potatoes, side salad and of course my Homemade Bread are some other suggestions.
Whatever you choose to serve with this amazing Grilled Flat Iron Steak with Gourmet Butter will be great because it's really the winner here!
