- The flavors blend together so well that this delicious marinade is going to become a fast family favorite!
A number of steak marinades I’ve found tend to use soy sauce, rendering them useless to those looking to stay gluten free because most soy sauces has gluten. This recipe uses gluten free tamari sauce instead. Which leads to the following question…
What’s the Difference Between Tamari and Soy Sauce?
They are in fact pretty similar, and if you were to pour each into a glass you’d likely not be able to tell the difference between the two without tasting them. Both are made from soybeans, with most soy sauces also using wheat. Typically tamari does not use wheat but be sure to read your labels as it can definitely sneak its way in there.
For more info on the differences and backgrounds of tamari and soy sauce, see these articles from Downshiftology and Chowhound.
You shouldn’t have any trouble finding gluten free tamari sauce at your local grocery store – it will be located in the same section as soy sauce typically is (just don’t pick that up by mistake). If you aren’t able to find it, you can always order it online.
Now on to the recipe.
How to make this gluten free marinade for steak
Start out by prepping the marinade (see the instructions in the recipe card below). The ingredients are shown here – there’s only eight of them. Told you this was going to be easy.
This is great to do the night before you plan on cooking the flank steak. Stick it in the fridge (covered) and in the morning you can just pop the steak and marinade in a ziploc bag to marinate in the fridge.
How To Grill Flank Steak
About 20 or 30 minutes before you’re ready to start cooking, take the steak out of the fridge to let it come to room temperature. If you don’t, the steak won’t cook evenly – yes, even flank steak, which is quite thin.
Once you’re steak is warmed up, turn up the grill to high heat (500 to 600 degrees F) and place the steak on it, closing the lid. Let it cook for 4 minutes, then flip and cook for another 4 minutes.
At this point you’ll want to check the internal temperature of the meat. If you don’t have a meat thermometer, you need to get one. We’ve had a Thermapen for years and I highly recommend it (it’s the purple one shown in the picture below).
Stick a meat thermometer in the thickest part of the steak and see what the temp is. A general guideline is 125 degrees F for rare, 140 degrees F for medium, and 160 degrees F for well done.
But this is key – you’ll want to remove your steak from the grill when it’s about 5 degrees below your ideal temperature. It will keep cooking once it’s off the grill so you need to factor that in. This article from Thermoworks goes into more detail about steak temperatures if you want more info.
If your steak isn’t at the right temp yet, shut the lid and cook it for another minute. Yes, I said one minute. Flank steak cooks very fast and is easy to overcook, so go in minute increments until you get the desired temperature on your steak.
Once it’s done cooking, set it on a large cutting board to rest for about 10 minutes. This is where those last 5 degrees cook the meat to the ideal doneness. After the 10 minutes are up, grab a sharp knife and a fork and start slicing away. I like to do more of a shave on flank steak, but I’ve seen a number of people like to cut it in pieces about ¼ to ½ an inch wide. Whatever way you like it is just fine.
Cooking Tips
- The marinade is on the salty side, so unless you REALLY like salt don’t marinate the steak overnight. On the flip side, if you only like lightly salted marinades you could do a 4 hour marinade to lessen the intensity a bit.
- Be sure and remove the meat from the grill 5 minutes before it reaches your desired temperature! It will continue to cook off the grill and you don’t want to end up with overdone steak.
- This dish goes well with roasted veggies and a carb-y side. Try it with my Gluten Free Instant Pot Potato Salad, Corn Tomato Avocado Salad, or Turmeric Roasted Cauliflower. Any leftovers (if you have them) also work well in a sandwich or salad.
Variations
- Use coconut aminos if you’re allergic to soy. You may need to add some salt to the marinade as it will turn out sweeter than when using tamari sauce.
- Try using ground ginger if you don’t have fresh. I typically use ½ teaspoon of ground ginger.
- If you don’t want to use wine, try substituting it for ¼ cup grape juice (red, not white) plus a tablespoon of vinegar (red wine vinegar or rice vinegar).
