Keto Low Carb Mongolian Beef, No Sugar!!

Posting Komentar
My Keto Low Carb Mongolian Beef is a healthy remake of the PF Chang’s classic take out!
The regular recipe is often loaded with sugar, but this healthy low carb version has no added sugar but still tastes really delicious, is naturally sweet, and my kids loved it way more than the classic version.

I used coconut aminos instead of gluten free soy sauce as it’s naturally much sweeter tasting because of the coconut but has no added sugars.

And the net carb count for my keto Mongolian Beef is pretty great at around 4g per serving with this recipe,  serving four people. Although if you have hungry teenagers like I do you may want to double the recipe!

how to make keto low carb mongolian beef

Start by cutting the steak into very thin slices against the grain

Then measure out your coconut aminos for the marinade.
You could use gluten free soy sauce instead, however coconut aminos are naturally sweet in a way that gluten free soy sauce is not so you will lose that sweetness in the recipe if you substitute them as we are not adding any sugar.
It will also be a lot saltier so you will probably need less soy sauce if you go that route.

Next, finely chop the garlic and grate the root ginger. Both of these will be added to the coconut aminos to create the marinade for your keto Mongolian Beef. Do not substitute this with powdered ginger in a jar that you typically use for baking, they do not taste the same and it simply won’t work as well.
I use this mircoplane tool to grate the ginger, it’s much easier than chopping it with a knife.

Add the garlic and grated ginger to the coconut aminos marinade and mix well together.
Then we’re going to add it to the already sliced meat.

Then you can either add it to a ziplock bag along with the sliced meat, or you can put it all in a bowl like I have it in the photo above.
You need to let it marinade for at least one hour in the fridge before it’s ready to cook.

While the meat for the keto Mongolian beef is marinating in the fridge you can cut the green onions.
You can chop and slice them any way you like, but cutting them on the diagonal makes for a pretty presentation.

When you are ready to cook you can remove the beef from the fridge and drain off the excess liquid, but don’t discard the liquid as we’ll add it back to the recipe at the end.
Get your large skillet or wok really hot and add the oil, if the oil is not hot enough you won’t get the nice crispy edges on the meat.
Then add the meat to the very hot skillet taking care not to add too much or it will steam the meat if the skillet is too full, so you may need to cook in a couple of batches depending on the size of your skillet.

You only need to cook the meat for your low carb Mongolian Beef for about 1-3 minutes or so, it cooks very fast.
You’ll also need to watch that you don’t burn it when you have the skillet on a high heat.

Then when the meat is almost finished cooking you can add the green onions and cook them briefly for about 30 seconds to a minute or so.
I also like to add the remaining sauce at this point along with the onions and let it reduce while the onions are cooking.
Then serve it hot!

more tips for making keto low carb mongolian beef

My top tip is to start with the right cut of meat!
Flat Iron steak or Flank Steak are my favorite cuts of beef for this recipe.Sirloin steak works too in a pinch, but the other cuts are better in my opinion and are much more likely to give you that nice crispy edge on the slices of meat.

Always make sure you slice the beef very thin, and against the grain for best results.

This will not only help the meat absorb the marinade, but it will ensure it cooks very quickly too.
I recommend seeking out coconut aminos for this recipe as opposed to using gluten free soy sauce. As I mentioned above we are not adding any additional sugar or sugar substitute here and the regular Mongolian Beef recipe is traditionally very sweet so this helps to get that sweet flavor we love, but without the carbs.

I have tried it by adding low carb sugar substitute but the flavors were not pleasant, so in my opinion the coconut aminos are a better option.

Although most of the recipes you’ll see online for Mongolian beef typically have a lot of starch added to make a thick sauce, if you have ever eaten the recipe at PF Chang’s you’d notice that it’s actually not cooked with a thickened sauce, so I like to think that my version is closer to the real thing!
Do remember to drain the meat from the marinade before you fry it.

This will help you get the deliciously crispy edges on your meat that the famous PF Chang’s Mongolian Beef is known for!

And lastly, the second tip for getting those great crispy edges is to have your oil really hot before you add the meat, preferably in a wok, but a cast iron skillet will work too.

Recipe Notes

Root Ginger – use only root ginger, this is not interchangeable with powdered ginger that you typically use in baking. You should be able to find ginger root at any grocery store so just ask if you are not sure. You need to peel it first and then grate it or finely chop it.
This recipe has approximately 4g net carbs per serving.
Some coconut amino brands have a higher carb count than others depending on the ingredients so read the label. I like Coconut Secret or the Kroger brand.
