Top Questions Answered About Gluten-Free Soy Sauce

7 March 2025

Soy sauce is a staple in many kitchens, offering a burst of umami flavour to countless dishes. But for those following a gluten-free diet, finding the right soy sauce can be a bit more complicated. Here are the top questions answered about gluten-free soy sauce to help you make informed choices in your cooking. 

Is soy sauce gluten-free?

Traditional soy sauce is not gluten-free. It is typically made with wheat, soybeans, salt, and water. During fermentation, wheat contributes to the sauce's rich flavour and aroma, but this means it contains gluten. For those with coeliac disease or gluten sensitivity, consuming traditional soy sauce could trigger adverse health reactions. 

Gluten-free soy sauces exist to cater to this need. These are made using alternative grains or ingredients that do not contain gluten, ensuring they are safe for gluten-free diets. 

How is gluten-free soy sauce made?

Gluten-free soy sauce is produced by replacing wheat with gluten-free grains like rice or using 100% soybeans in the brewing process. The fermentation process is similar to traditional soy sauce, maintaining the signature umami flavour. The absence of wheat ensures no gluten contamination, making it suitable for those with dietary restrictions. 

When selecting gluten-free soy sauce, it is important to check for gluten-free certification on the packaging. Look for labels such as "Certified Gluten-Free" or symbols like the crossed grain logo to ensure the product has been tested and verified as gluten-free.  

How can I tell if soy sauce is gluten-free?

The best way to determine if soy sauce is gluten-free is by examining the product label. A "gluten-free" designation ensures that the product contains less than 20 parts per million (ppm) of gluten, which is considered safe by regulatory standards, including the UK's Coeliac Society guidelines. 

Additionally, reading the ingredient list can provide further clarity. Gluten-free soy sauces typically avoid wheat and may use rice, soybeans, salt, and water as primary ingredients. 

Can I substitute regular soy sauce with gluten-free soy sauce in recipes?

Yes, gluten-free soy sauce can be used as a direct substitute for traditional soy sauce in recipes. It maintains the same balance of salty, savoury, and slightly sweet notes, making it versatile for all types of dishes, including stir-fries, marinades, soups, and dressings. 

When using gluten-free soy sauce in recipes, a 1:1 substitution ratio works perfectly. This ensures the flavour and consistency of the dish remain unchanged, while keeping the meal safe for gluten-sensitive individuals. 

Can I use gluten-free soy sauce in cooking and dipping?

Gluten-free soy sauce is just as versatile as traditional soy sauce. It can be used for: 

  • Marinating: Adds depth of flavour to meats and vegetables. 

  • Stir-Frying: A go-to ingredient for Asian-inspired dishes. 

  • Dipping Sauce: Mix with fresh ingredients like ginger, garlic, and chilli for a gluten-free dipping sauce. 

  • Seasoning: Use as a low-calorie, gluten-free alternative to salt in recipes. 

When cooking for those with gluten sensitivities, it is important to avoid cross-contamination in the kitchen. Use separate utensils and cookware when preparing gluten-free meals. 

What are the best gluten-free accompaniments for soy sauce?

Pairing gluten-free soy sauce with the right foods means you can enjoy authentic dishes from around the world. Some popular, naturally gluten-free accompaniments include: 

  • Rice Noodles: Ideal for Asian dishes like stir-fries, soups, and cold noodle salads, as they absorb the rich flavours of soy sauce-based sauces. 

  • Sushi: Enjoy sushi with gluten-free soy sauce for dipping. Ensure that the sushi rice, fillings, and any additional sauces are also gluten-free to avoid cross-contamination. 

  • Vegetable Stir-Fries: Combine fresh vegetables with gluten-free soy sauce to create a quick, healthy, and satisfying gluten-free meal.  

  • Quinoa: These grains are perfect as a base for bowls or as a side dish, allowing soy sauce dressings to infuse each bite with savoury goodness. 

  • Rice Paper Wraps: When made with 100% rice flour, rice paper wraps are naturally gluten-free. They pair well with fresh vegetables, herbs, and a soy sauce-based dipping sauce for a light, gluten-free meal. 

These pairings not only keep meals gluten-free but also enhance the authentic taste of your dishes. 

Is Gluten-Free Soy Sauce Healthier?

Nutritionally, gluten-free soy sauce offers similar benefits to regular soy sauce. It is low in calories and contains beneficial amino acids due to the fermentation process. The primary advantage is that it is safe for those who need to avoid gluten. 

Gluten-free soy sauce is an excellent choice for anyone on a gluten-free diet or looking to avoid gluten in their meals.
