Vegan fish sauce: what it is made from and how to use it

Published 5 min readBy the Nashville Pantry Guide team

Short answer

Vegan fish sauce is a plant-based stand-in for fish sauce, made from ingredients such as seaweed, soy sauce, mushrooms, pineapple or fermented soybeans. It adds salt and savory depth to dips, stir-fries and noodles without any fish.

Vegan fish sauce is a plant-based seasoning designed to replace fish sauce in cooking, usually made from seaweed, soy sauce, mushrooms, pineapple or fermented soybeans. It is salty and savory with a hint of the sea, and it works in dips, stir-fries, noodle bowls and soups without using fish.

What is vegan fish sauce made from?

Vegan fish sauce is made from plant ingredients that supply salt and umami, the savory taste that fish sauce is known for. Common bases are kelp or other seaweed, soy sauce, dried shiitake mushrooms, fermented soybeans and, in some brands, pineapple or coconut.

Seaweed contributes a briny ocean note. Mushrooms and soy add deep savory flavor. Pineapple or sugar balances the salt, and some bottles include vinegar or spices. Because recipes differ by brand, the ingredient list tells you what is in your bottle.

How does vegan fish sauce taste?

Vegan fish sauce tastes salty, savory and slightly sweet, with a faint seaweed or mushroom background. It is less pungent than regular fish sauce and has no fermented fish smell.

Expect the flavor to depend on the base. A seaweed version tastes briny and clean. A soy version tastes darker and closer to a seasoned soy sauce. A pineapple version has a light fruity edge. None of them is identical to the original, but in a balanced dish most people find the difference small.

Which types of vegan fish sauce are there?

There are four common types: seaweed based, soy and mushroom based, fruit based and homemade. The table compares them.

Type Main ingredients Taste Good for
Seaweed based Kelp, salt, water Briny, clean Dips and soups
Soy and mushroom based Soy sauce, shiitake Dark, savory Stir-fries, marinades
Fruit based Pineapple, soy, salt Slightly sweet, mild Dressings, noodles
Homemade Mushrooms, kelp, soy Adjustable Everything, if made fresh

How do you use vegan fish sauce in recipes?

Use vegan fish sauce the way you would use regular fish sauce, as a salty seasoning added in small amounts. Start with the same quantity the recipe lists, taste, and adjust.

Good places to use it:

  • Stir-fried vegetables, tofu and noodles.
  • Vietnamese style dipping sauce with lime, sugar, garlic and chili.
  • Thai style salad dressings and noodle bowls.
  • Soups and broths for extra depth.
  • Marinades for mushrooms, tofu or grilled vegetables.

Because the sauces vary in saltiness, taste the dish before adding extra salt.

How do you make a vegan nuoc cham?

Vegan nuoc cham is made by replacing the fish sauce in the classic Vietnamese dipping sauce with a vegan fish sauce or a mix of soy sauce and seaweed seasoning. The rest of the sauce stays the same.

  1. Dissolve 3 tablespoons of sugar in 1/2 cup of warm water.
  2. Add 1/4 cup of vegan fish sauce and 1/4 cup of lime juice.
  3. Add 1 minced garlic clove and sliced chili.
  4. Taste and adjust the sweet, sour and salty balance.

Serve it with spring rolls, rice noodles or grilled tofu. It keeps for several days in the refrigerator.

How do you make vegan fish sauce at home?

You can make vegan fish sauce at home by simmering dried mushrooms and kelp in water, straining, and adding soy sauce and a little sugar. It takes about 45 minutes, most of it hands off.

  1. Soak 6 dried shiitake mushrooms and a 4-inch piece of kelp in 2 cups of water for 30 minutes.
  2. Simmer gently for 20 minutes, then strain the liquid.
  3. Add 1/4 cup of soy sauce, 1 tablespoon of sugar and a small piece of crushed garlic.
  4. Simmer until reduced by about half and cool.

The finished sauce is salty and savory. Keep it in a covered jar in the refrigerator and use it within about a week.

What should you check on a vegan fish sauce label?

Check the ingredient list for anything you want to avoid, such as wheat, soy or added sweeteners. Not every product labeled vegan is also gluten free, and some include sugar or flavorings.

  • Wheat: soy sauce is often made with wheat, so look for tamari or a gluten-free note.
  • Salt level: compare the sodium figure between bottles if you are choosing by saltiness.
  • Allergens: soy is a common ingredient, and some blends also use sesame.
  • Storage: many need refrigeration after opening.

This is general guidance, so read the actual label and ask the maker if you have an allergy or dietary need.

Vegan fish sauce vs regular fish sauce: what is the difference?

Regular fish sauce is made by fermenting fish with salt for months, which gives a deep, pungent, savory liquid. Vegan fish sauce uses plants to copy the salty savory taste without fish.

Feature Regular fish sauce Vegan fish sauce
Main ingredients Fish, salt Seaweed, soy, mushrooms
Smell Pungent, fishy Mild, briny or soy-like
Fermentation Months Often none
Flavor Deep, funky, salty Salty, savory, lighter
Suitable for plant-based cooking No Yes

What dishes work best with vegan fish sauce?

Vegan fish sauce works best in dishes where fish sauce is a supporting flavor, such as stir-fries, noodle soups and marinades. In dishes where fish sauce is the star, such as a classic dipping sauce, the difference is easier to notice, but a balanced vegan version still tastes good.

Try it in pad thai style noodles, fried rice, vegetable curries, tofu marinades and papaya or cabbage salads. Add it in stages, tasting as you go, because the saltiness of vegan bottles varies. A squeeze of lime, a pinch of sugar and a little chili bring the flavor closer to the Southeast Asian original.

Is vegan fish sauce the same as soy sauce?

No. Soy sauce is a single, well-known fermented seasoning, while vegan fish sauce is a blend designed to taste closer to fish sauce. Many vegan fish sauces contain soy sauce, but they add seaweed, mushrooms, fruit or sugar to round out the flavor.

If you do not have a vegan fish sauce, soy sauce with lime juice is a good stand-in, and the swap is covered in the guide to fish sauce substitutes on this site’s guides page.

Common questions

Does vegan fish sauce taste like real fish sauce?

Not exactly. It matches the saltiness and savory depth but lacks the fermented fish note. Seaweed versions come closest to a briny, ocean taste, while soy and mushroom versions taste more like a dark savory sauce.

How much vegan fish sauce replaces regular fish sauce?

Start with the same amount as the recipe calls for, then taste. Some bottles are saltier than fish sauce, so you may need less, and a squeeze of lime often helps balance it.

Is vegan fish sauce gluten free?

Not always. Some bottles use soy sauce made with wheat. Look for a label that says gluten free or uses tamari, and read the full ingredient list of the bottle you buy.

Can I make vegan fish sauce without special ingredients?

Yes. Simmer dried mushrooms and a piece of kelp in water, strain, and stir in soy sauce and a little sugar. Reduce by half. The result is salty, savory and keeps about a week in the refrigerator.

How long does vegan fish sauce last once opened?

Follow the storage line on the bottle. Many are kept in the refrigerator after opening and used within a few months. A homemade version lasts a shorter time, about a week, in a covered jar.
