🗝️ Key ingredients & substitutions

Six small bowls arranged on a wooden surface, containing sesame oil, tamari (or soy sauce), sherry, garlic and ginger mix, brown sweetener, and xanthan gum. Each bowl is labeled with its contents.
  • Tamari or Low-Sodium Soy Sauce: The heart of that umami-rich flavor! For a gluten-free option with more depth, go for tamariCoconut aminos is a great alternative if you’re avoiding soy, but the carbs can be a little higher.
  • Brown Sugar Substitute: Keeps it keto without sacrificing sweetness. Monk fruit or erythritol blends work well here.
  • Sesame Oil: Adds a toasty, authentic note. Use avocado oil if you want a more neutral flavor.
  • Fresh Ginger & Garlic: These two pack a punch, giving the sauce a zesty kick. For a quick fix, ground ginger and garlic powder will do.
  • Xanthan Gum: A little goes a long way to thicken the sauce. If you’re out, an arrowroot slurry works too, but adds a bit of carbs.
  • Sherry: Adds depth and a hint of tangy sweetness. You could swap with a splash of rice wine vinegar for a bit more sharpness.

🥣 How to make keto teriyaki sauce

  1. Heat the Sesame Oil: Add 1 tablespoon sesame oil to a small saucepan over medium-high heat. When it’s hot and shimmering, you’re ready for the next step!
  2. Sauté the Ginger and Garlic: Toss in minced ginger and garlic, letting them cook for about 2 minutes until they release that amazing aroma.
  3. Add Tamari and Sweetener: Pour in the tamari and brown sugar substitute, along with the sherry. Give it a good stir, and let the mixture simmer for about 10 minutes to meld the flavors.
  1. Make the Xanthan Gum Slurry: In a small bowl, gradually mix xanthan gum with water, adding it slowly until you get a thick paste.
  2. Thicken the SauceStir the slurry into the saucepan, whisking until the sauce becomes smooth and thick. Then, take the pan off the heat.
  1. Use it as a marinade, serve over chicken, beef, veggies, or as a dip, and enjoy!

🪄 Recipe notes & tips

  • Control the Thickness: Start with a small amount of xanthan gum, as a little goes a long way. Add more gradually if you want a thicker sauce. The more you mix, the thicker the xanthan gum will become!
  • Taste Test: Everyone’s preference for sweetness and saltiness is different! Feel free to adjust the brown sugar substitute or tamari to get the perfect balance for your palate.
  • Make It Ahead: This sauce keeps well in an airtight container in the fridge, so you can whip it up ahead of time for easy weekday meals.

✨ Variations

  • Spicy Kick: Add a dash of chili flakes or a few drops of sriracha to bring some heat to your keto teriyaki sauce.
  • Sweeter Twist: For a touch more sweetness, use a bit of keto-friendly maple syrup.
  • Garlic LoversDouble up on minced garlic if you’re a fan of that bold, garlicky flavor.
  • Citrusy: Try adding a hint of lemon or orange zest for a bright, tangy note.
  • Veggie Boost: Toss in some stir-fried green beans or hibachi vegetables to make a full meal.
  • Soy-Free Option: Use coconut aminos instead of tamari if you’re looking to keep it soy-free and paleo-friendly. You may want to reduce the amount of sweetener used as coconut aminos are a little sweet already.
