Ingredients needed

Here are all the ingredients that go into my authentic keto Mongolian beef recipe:

Flank steak

The base of this dish is thinly sliced flank steak. You can swap for any cut of beef you prefer, though flank steak gives the most authentic texture. 

Coconut aminos

For a salty, umami flavor, I add a healthy bout of coconut aminos to my Mongolian beef sauce. Tamari or gluten-free soy sauce can also be used in a pinch.

The rest of the sauce is thinned out with equal parts water. 

Erythritol

To sweeten the dish, I use erythritol. Feel free to use your favorite low-carb sweetener.

Garlic and ginger

Arguably, the most important ingredients in this dish are fresh minced garlic and ginger. These flavor enhancers totally make the dish!

Olive oil

To grill the flank steak, I like to use a bit of olive oil. This also adds some additional fat content (your macros will thank you!). 

Green onion and sesame seeds

Green onion and sesame seed garnishes complete this recipe, adding bright and nutty flavors. 

Cauliflower rice

Cauliflower rice is always a great base for dishes like this because it soaks up all of the delicious sauce. It’s optional, but I highly recommend it.

Cooking tips

  • Use more or less sweetener depending on your flavor preference. 
  • Don’t overcook your beef; it’ll get chewy fast!
  • Enhance your recipe by including the optional garnishes. Green onion brings a necessary brightness, while sesame seeds add a nutty crunch.

FAQs

Have more questions about my keto Mongolian beef recipe? I’m here to help! If you have any more questions for me, please leave them in the comments below. 

What makes Mongolian beef a keto recipe?

In its authentic form, Mongolian beef is almost keto-friendly. A few things fall short:

1. It’s sweetened with high-carb sweeteners.

2. It includes soy sauce, which is made with wheat, a non-keto ingredient.

3. Often, the sauce is thickened with high-carb cornstarch or flour. 

To make this recipe low-carb, I substitute soy sauce with coconut aminos and sugar with erythritol. 

Is keto Mongolian beef gluten-free?

My Mongolian beef recipe is 100% gluten-free and suitable for celiacs.

Please note the ingredients list on all packaged products, particularly the coconut aminos. While they are naturally gluten-free, you’ll want to be sure there is no chance of cross-contamination through the manufacturer. 

How can I thicken keto Mongolian beef sauce?

Usually, we use cornstarch or flour roux to thicken a sauce. On a keto diet, however, neither of these options works!

Instead, you can use a tiny bit of xanthan gum to help thicken your Mongolian beef sauce if necessary. While it looks suspiciously like corn starch, xanthan gum is low-carb and keto-friendly. 

Can I add vegetables to keto Mongolian beef?

You can absolutely add some tasty low-carb vegetables to this dish. In fact, I recommend it!

Keto vegetables like broccoli, bell peppers, green beans, and bean sprouts would all make great additions to this dish. Be sure to cook them in your prepared sauce for the best flavor. 

If you want to add sneaky vegetables to this dish, a bed of cauliflower rice when serving is your best option; the texture is so similar to rice, especially when topped with the beef.
