Keto Soy Sauce Alternative (Soy Free!)

posted in: Recipes

Last Updated on

Use a keto soy sauce substitute when you need an alternative option for marinades and stir fry. This homemade low carb approved recipe is sugar free, soy free, and wheat free so you can still eat soy sauce on a keto diet without any negative effects!

Cooking easy keto recipes at home is more rewarding and often more delicious than relying on store-bought foods and eating out.

Is soy sauce keto?

Soy sauce contains soy and wheat (shoyu) which are two ingredients we typically avoid on keto.

In general, soy isn’t the greatest food. Regular doses of soy aren’t recommended on a keto diet (or any human diet for that matter) especially if you have high levels of inflammation, endocrine disruption, and hormone imbalances.

However, the carbs in soy sauce are very low per serving.

A splash of soy sauce every once and a while (probably) won’t kill your progress or wreck your health.

If you’re out at sushi and want to dip the sashimi for the quick swim in the sauce, go for it and enjoy it.

Keep it in perspective and stay focused on keto foods for the rest of the meal.

How many carbs in soy sauce?

According to Fat Secret, the average between brands of soy sauce is 1.2 grams of carbohydrate per 1 tablespoon of soy sauce. Low or reduced-sodium soy sauce tends to have slightly more.

Kikkoman Soy Sauce, one of the most popular brands in the US, has 10 calories per 1 tablespoon of liquid coming from 1 gram of protein and 1 gram of carbohydrate.

As you can see, there is a negligible amount of carbs in soy sauce.

If you are like me, the motivation to make a keto approved alternative to soy sauce comes from wanting to avoid the soy more than the carbs.

Sugar Free Keto Soy Sauce Substitute

Making a homemade keto soy sauce substitute replicates all the best flavors from traditional soy sauce but without the soy!

Cooking from scratch will always be healthier than not because you get a greater degree of control over your food.

By using fresh, unprocessed ingredients, your meals will be free of chemical stabilizers, food preservatives, “natural flavors,” endocrine-disrupting dye, not to mention sugar too.

Also, if you are allergic to soy, this low carb soy sauce alternative will be just what you want. 

It is allergen-free; there is no wheat or soy in this recipe.

How to Make Keto Soy Sauce Recipe

This quick and easy Keto Soy Sauce Substitute recipe will walk you through the simple process of making a keto soy sauce alternative at home. 

From start to finish, you’ll spend about 20 minutes before your Asian-inspired, sugar free, soy free keto soy sauce option is ready.

Begin by adding all the ingredients, except the salt, to a saucepan and bring to a simmer over medium heat.

Maintain this for about 15 minutes, until the liquid has reduced by a third.

Season with salt.

Transfer to a bottle or jar with a tight-fitting lid. Store in the refrigerator for up to 1 week. Shake well before using.

You may see the sauce gel after sitting in the fridge. This is due to the gelating in bone broth that firms as it chills. If this happens, bring your homemade soy sauce to room temperature before serving and stir well to recombine the flavors.

Serve in a bowl for dipping or add it into your favorite keto meals!

This healthy soy sauce recipe is great on cabbage noodles.

Low Carb Soy Sauce Alternatives

Like many of my everyday keto recipes, this keto soy sauce substitute does not call for any special ingredients or fancy equipment.

It’s a simple recipe anyone can make!

If you don’t have the time to prepare this homemade soy sauce recipe, you can also use one of the two store-bought keto friendly soy sauce alternatives.

Coconut aminos The sauce is made from the “sap” (actually coconut-blossom nectar) of coconut palms. The sap is fermented and then blended with sea salt.

Coconut aminos are a good choice for people with soy allergies and others who want to avoid soy in general. I recommend Coconut Aminos by Coconut Secret. You can purchase it online or look at your local health food store.

Fish sauce One of the most popular condiments used in Southeast and East Asia is fish sauce. It is the result of fermenting heavily salted fish for a few weeks (in some cases up to two years!). You can find this heritage food in Asian grocery stores and specialty markets.

Look for a formula with no sugar. It may be unavoidable, so check the total carbs per serving on the nutrition label to confirm the amount is minimal. Since you use just a little, it may not be a problem. 

I recommend the Thai Kitchen brand. They have a sauce that is free of preservatives, stabilizers, and chemical flavorings.
