  • ¼ teaspoon xanthan gum
  • 1 tablespoon water
  • ¼ cup reduced sodium soy sauce
  • 1 tablespoon rice vinegar
  • ½-1 tablespoon Swerve, granular (or Swerve brown; I used ½ tablespoon, use more if you want sweeter teriyaki sauce)
  • 1 clove garlic, minced
  • 1 teaspoon toasted sesame oil
  • ½ teaspoon fresh ginger, grated


  • Whisk the water and xanthan gum together. It will form a gel quickly.
  • Add the soy sauce, rice vinegar, Swerve, garlic, sesame oil, ginger, and xanthan gum mixture to a small saucepan. Whisk well to combine.
  • Put the pan over medium heat and whisk until it is thick and glossy. This takes about 10-12 minutes. Do not let it turn into a gelatin-like consistency, you want a pourable sauce.
  • Use your sauce immediately in your favorite teriyaki recipes. Enjoy!


This is a level 1 recipe (may help support fat loss). This sugar free teriyaki sauce is a low calorie and low carb condiment that can add rich umami flavor to a meal. Are you eating a lot of protein and non-starchy veggies as part of your weight loss strategy? A little teriyaki sauce can help keep your meals from getting boring. 
A little is key here. This sauce is really too strong to be used as a dipping sauce. This recipe makes enough teriyaki sauce to flavor at least 2-3 meals, so enjoy some teriyaki chicken with the whole family! 
Benefits aside, this is still a high sodium condiment, even though I used reduced sodium soy sauce. Teriyaki sauce is not the best choice for flavoring if you’re on a low sodium diet. Instead of teriyaki sauce, try flavoring foods with herbs, citrus juice, or citrus zest instead. 
Also keep in mind that “low sodium soy sauce” will usually be much lower in sodium than “reduced sodium soy sauce.” If you need a lower sodium option, make sure your soy sauce says “low sodium” on the label. Servivita Zero Calories Soy Sauce is one of the lowest sodium soy sauce options I’ve found. 
On the other hand, if you’re on a low carb or keto diet, your levels of electrolytes (including sodium) can drop. In this case, being more liberal with your intake of sodium may help. This keto teriyaki sauce may help you to replenish some of the sodium losses that can result from a very low carb diet pattern.
