Vegan fish sauce is a flavorful and conscientious alternative to the beloved Southeast Asian condiment. We’ll shed some light on its benefits and how you can make a delicious plant-based sauce at home. 


In a fascinating testament to its versatility, fish sauce has traveled through many centuries and cultures to retain its spot at the table. The first reported origins of fish sauce hark as far back as Ancient Greece and Rome, where the condiment was known as gàros or garum. 

Remarkably, the Italian archaeologist Claudio Giardiono has traced the earliest mentions of fish sauce in Roman literature as far back as the 4th century BC. In the Eastern hemisphere, fish sauce enjoys enduring popularity in Southeast Asian cuisine. 

In Thailand, where’s it added open-handedly to most dishes, fish sauce is known as nam pla, and in Myanmar, it’s ngan bya ya. It’s also highly cherished in Laos, Cambodia, and the Philippines. Regardless of its ever-evolving names, one fact stands the test of time. Fish sauce plays a vital role in enhancing many excellent dishes, which brings us to how it’s used – and why vegan fish sauce might be a better alternative. 

How Fish Sauce is Used

With its distinct reddish-golden-brown color, fish sauce is employed as a flavorful base for many dishes. It’s often used to marinate fish, chicken, and other meat dishes, plus homemade soups, salads, curries, stir-fries, pad thai, and omelets. Traditionally, it’s mixed with fresh chilies and lime juice to produce a bold, unmistakable flavor. 

At its essence, fish sauce is typically comprised of three key ingredients: 

  • fermented fish
  • water
  • salt

    Generally, the fish (typically anchovies) are placed in a barrel with salt and left to ferment, taking between several months right up to two years. Next, the fish are pressed down so that the fish sauce liquid itself can be extracted.  

    Although some brands may deviate slightly from this simple formula, and occasionally use other fish like shrimp or squid, the basic formula of a traditional fish sauce remains fish, water, and salt. Occasionally molasses or caramel are used to enrich the flavors. 

    Vegan Fish Sauce: A Better Alternative 

    Although the name vegan fish sauce might seem a bit of a misnomer, it’s a much more sustainable and ethical alternative for dishes that lean on fish sauce for a base. Although fish is arguably a great source of Omega 3, it’s more than convenient to obtain Omega 3 from flaxseeds, hemp seeds, chia seeds, and walnuts. 

    On an ecological level, the fishing industry’s consequences have colossal and troubling implications that are bigger than all of us. The irreversible damage to the environment caused by overfishing and habitat destruction is occurring the world over at a highly alarming, unprecedented level, and will surely contribute to a loss in biodiversity.

    To make matters worse, many more species of fish become entangled in the bycatch, leading to a further loss of marine life. Although many food manufacturing companies sing the tune of ethical fishing, the bitter truth is that the legislation surrounding the fishing industry has many loopholes that are exploited.  

    On another ethical level, fish have been shown time and time again to exhibit feelings and display social bonding behaviors. When it comes to the pecking order for valued species, it seems the sentience of marine life is often disregarded in the debate. 

    Finally, another reason why you should strive towards vegan fish sauce comes down to its benefits for your health. The classic fish sauce fermentation process involves a lot of salt, which means that ordinary fish sauce contains unhealthy levels of sodium. 

    Not only will vegan fish sauce have lower levels of sodium,  the fact that it’s plant-based means that people with seafood allergies will finally be able to enjoy it in their cooking.
