Instructions

Begin by adding 1 tablespoon of sesame oil to a saucepan over medium-high heat.
1.5 tablespoons sesame oil
When hot, add the ginger and garlic, and sauté for 2 minutes until fragrant.
1 1/2 teaspoons fresh ginger, 1 teaspoon garlic
Add the tamari, brown sugar substitute, and sherry. Stir and simmer for 10 minutes.
1/2 cup tamari, 1/4 cup brown sugar substitute, 3 tablespoons sherry
When the sauce has simmered for 10 minutes, make a xanthan gum slurry by adding the xanthan gum to a small bowl. Gradually add the water, 1 teaspoon at a time to start, until it becomes a thick sauce.
1/2 teaspoon xanthan gum, 1/4 cup water
Add the slurry to the sauce, and whisk continuously until it is smooth and thick. Remove the pot from the heat and serve or store it for later.

Notes

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.

Storage instructions

Fridge Storage: Keep any leftover keto teriyaki sauce in an airtight container or mason jar in the fridge. It’ll stay fresh and flavorful for up to a week.

Freezer-Friendly: Want to make a big batch? Freeze in a freezer-safe container for up to 3 months. Just thaw it in the fridge overnight when you’re ready to use it.

Reheat with Care: Gently reheat on the stove over medium heat, stirring frequently. Avoid microwaving if possible to keep the sauce texture smooth.
