Do you have old recipes that you love but forgot about? That’s the beauty of having  food blog. You have all your favorite recipes at your fingertips. This keto marinated grilled flank steak is an old favorite that my mom used to make in the summertime.

She would use blue cheese dressing as the marinade for flank steak and grill it during the summer. We ate this quite often and I loved it. So I when I remembered it I had to make it a post because it is so easy and definitely a low carb recipe that I thought my readers would love.

There are a few tips you have to remember but it only requires a bottle of blue cheese and a flank steak so it’s the perfect steak dinner for busy weeknights. This is also a high protein, low carb dinner with just 1.6 grams net carbs and 32.9 grams protein per serving.

And don’t worry if you aren’t a fan of blue cheese dressing, you won’t taste it when the meat is done grilling. It will create a juicy and tender steak and just give it tons of flavor.

The 2 recipe ingredients I used and substitutions.

Since you only need two simple ingredients this recipe doesn’t get any easier. I used bottled blue cheese and a flank steak. No need to season with salt and black pepper, just the dressing. Though I love black pepper on and kind of steak.

Flank Steak
This meat is a good marinating steak as it makes this cut of meat more tender and imparts lots of flavor. Plus it’s great to grill and doesn’t take much time. You could probably use a skirt steak as well but I have not tried that yet.

It’s a lean piece of meat and should be cut against the grain when carving. You can learn all about different cuts of beef and how to prepare them on  Certified Angus Beef® website. They all have useful recipe videos.

Blue Cheese Dressing
You can use any brand of bottle blue cheese dressing you want. I do not have a favorite because you really don’t taste the dressing on the steak after it’s been grilled.

If you wanted to substitute you could possible try ranch dressing, though I have not done this. I’m guessing that this could work because it’s similar type of dressing but just doesn’t have the cheese in it. I’ll have to try that and get back to you!

How to make keto marinated grilled flank steak.

Step 1: The first thing you want to do is prep the steak by scoring both sides so that it absorbs more of the dressing.

Look at the grain of the meat which the direction the tough muscle fibers are aligned. It’s pretty easy to see on a piece of flank steak.

You want to score a diamond pattern in the meat so the dressing soaks in. Slice lines going in one direction then slice the other way to make the diamond cut. Do this on both sides. Be careful and try not to cut too deeply. Just enough so the blue cheese will seep into it.

Step 2: Next add about ½ bottle of blue cheese dressing marinade over steak on both sides of the meat and let it marinate overnight. You can place it in a marinating container like this, large ziplock bag or even a baking dish.

The longer the marinating time the better it will be for optimal flavor do it overnight.

Step 3: When ready to grill the meat, take it out and let it come to room temperature for about 15 minutes. Then take the steak from marinade and place it on an outdoor grill.

You want to grill each side over high heat for at least 5-10 minutes on both sides. I like mine to be charred on the outside but pink in the middle. If you use a meat thermometer to get the internal temperature, medium rare is usually 135 degrees F in the middle and 145 degrees F for medium.

 So grill it for 10 minutes on each side and use a meat thermometer. If you don’t have a meat thermometer you can always cut a small piece off! Note cooking time may vary.

Please Note: You really need to grill this blue cheese marinated flank steak. Otherwise you will have a sickly looking, gray piece of meat. You want the heat to burn up that white blue cheese. Believe it’s worth it though. It has so much flavor!

Step 4: Once the meat is done, let the steak rest for about 5 – 10 minutes to seal in the juices. Then slice steak but make sure to cut against the grain as it makes the meat tender. If you want to know exactly how to do that, here’s a great article on how and why to cut against the grain.

I like to place the slices of beef on a platter for everyone to serve themselves. You can garnish with fresh herbs or even grill veggies while you’re doing the steak and serve them on the platter as well.
