Vegan Fish Sauce

Fish sauce is a common ingredient used many Southeastern and Eastern Asian cuisines, among those Thai food. It lends a distinctive umami flavor to many dishes, and Thai food really doesn’t taste like Thai food without it. It is typically made by fermenting whole fish, or fish blood with salt- but there is also a vegan way to capture this flavor.

The real secret to getting a fishy flavor without the fish is by finding underwater vegetation- seaweed. I used a couple different varieties I picked up when I spent a week up on Grand Manan Island, in New Brunswick. I got them at Roland’s Sea Vegetables, which provided at least a dozen different varieties of dried seaweeds- in the end I got 4-5 types, including dulse flakes and alaria (which is similar to wakame). I used both of them in the creation of this fish sauce, and found the flavor deeper and more delicious than when I had made it in the past with only dulse. I highly recommend this combination of seaweeds, but you should feel free to experiment with the types that are available to you.

Vegan Fish Sauce


  • 3 cups of water
  • 4 cloves of garlic
  • 1 tsp. of Chinese peppercorn
  • ½ cup of dulse flakes
  • ½ cup of dried alaria seaweed
  • ½ cup of mushroom soy sauce


1. In a medium sized sauce pan, add the water, garlic, peppercorn and seeweeds and bring to a boil. Reduce to a simmer and continue to cook, stirring occasionally, for 25 minutes.

2. Strain the solids from the liquid, and return the pot to the stove. On medium-low heat add the soy sauce and continue to cook down, until the liquid tastes slightly fishy and very salty. Refrigerate for future use.

  1. What an incredible idea! Really answers the “I can’t have that because it will contain fish sauce” issue!
