How do you make a keto stir fry sauce? 

The Ingredients

  • Chicken or vegetable broth– Instead of using water, using broth will make the sauce even more flavorful. It also cuts out any salt, pepper, or spices. 
  • Soy sauce– Standard soy sauce or gluten free soy sauce. Do not use dark or flavored soy sauce, as their flavors can be quite overpowering and often contain added sugars and carbs. 
  • Fish sauce– Adds a delicious and umami flavor to the overall stir fry sauce. Don’t worry about any fish flavors or tastes, as it is not evident at all. 
  • White vinegar– Adds an overall tanginess and helps the sauce stick to the protein and vegetables. Apple cider vinegar can also be used. 
  • Granulated sweetener of choice– Every good stir fry sauce needs some sweetness to balance out all the salty flavors. To keep it low carb, use a keto powdered sugar or brown sugar substitute
  • Xanthan gum– Optional, but adding a dash of xanthan gum thickens the sauce considerably. 

The Instructions

In a small bowl, whisk together all the ingredients until combined. 

To add to a stir fry- Cook your protein and vegetables until tender. Pour the sauce over them in the pan and cook for 4-5 minutes, until the sauce is bubbling and has reduced.
