Keto Mongolian Beef – Low Carb Copycat Recipe

keto Mongolian beef

This Keto Mongolian Beef recipe is so easy to make. It may be keto-friendly, but the taste is similar to the Mongolian beef dish that you get at PJ Chang’s or your favorite Chinese restaurant.

To make this copycat recipe from Jennifer Banz keto-friendly, a low-carb sweetener was used instead of sugar. And while the traditional recipe uses cornstarch to coat the beef, this recipe does not use any coating.

Xanthan Gum

Also, instead of adding cornstarch to thicken the sauce, Xanthan gum was used. This ingredient is keto-friendly and will give the sauce a similar consistency.

Xanthan gum is used in food manufacturing as a thickener or stabilizer. Although it’s created in a lab it’s actually a soluble fiber. In large amounts it can cause digestive upsets in some susceptible people but it’s generally considered to be safe.

You can eat this Keto Mongolian Beef with a cup of low carb cauliflower rice. It’s perfect for lunch or dinner, and you can even cook it for your weekend gathering with friends. Whether they are on the keto diet or not, they will surely love this savory dish!

Is Soy Sauce Keto Friendly?

This recipe calls for soy sauce or coconut aminos. Different makes of soy sauce vary in the amount of carbs they contain so coconut aminos is probably a better choice. One once contains about 1.6 grams net carbs.

Soy sauce also contains gluten which is not good for your gut so is not ideal. If you prefer soy sauce to coconut aminos then look for Tamari Soy Sauce which is usually gluten free.

Check the label carefully if you have to be gluten free because some brands are not truly gluten free. They just claim to use less wheat. Tamari generally contains only 1.4 net grams carbs per ounce.

Coconut aminos are popular among people who want to avoid soy. The majority of soy is genetically modified and the crops are highly sprayed with pesticides. You would be safe to buy organic products like this Tamari Soy Sauce.

Coconut amino products are lower in sodium, milder, and slightly sweeter than Tamari or Soy Sauce.

Keto Mongolian Beef


  • 1 ½ pounds Flank Steak or Flatiron Steak
  • 2 tsp. minced ginger
  • 2 tbsp. avocado oil
  • ½ cup soy sauce or coconut aminos
  • 1 tbsp. minced garlic
  • ¾ cup granulated sweetener such as Lakanto monkfruit sweetener 
  • ¼ tsp. red pepper flakes
  • ½ cup filtered water
  • 5 stems of green onions, sliced on the diagonal into 2″ pieces
  • ¼ tsp. Xanthan gum


Prepare the Sauce:

1. Place a medium sized pan on medium heat and heat 1 tbsp of the avocado oil.
2. Add the garlic, ginger, and red pepper flakes. Stir until combined for about 30 seconds.
3. Add the water, coconut aminos and sweetener and bring it to a boil. Simmer for about 5 minutes or until the sauce has thickened.
4. Remove the sauce from the pan, pour it into a bowl and set aside.

Cook the Steak:

1. Hold the knife at a 45-degree angle and slice the flank steak into about 1/4 inch slices.  Cut the long pieces in half in order to make them much easier to bite.
2. Heat the remaining 1 tbsp avocado oil in a skillet and cook the beef. You may need to cook it in two batches so as not to crowd the pan.  Cook for about 2 to 3 minutes until brown turning them to get both sides cooked.
3. Pour the sauce into the skillet and add the Xanthan gum.
4. Cook for a few minutes more over medium-high heat. Stir well to coat the meat.
5. Add the green onions before removing the Keto Mongolian Beef from heat.
