When it comes to cooking up a storm in the kitchen, having the right condiments can make all the difference. If you’re familiar with Thai recipes, you’ll know that fish sauce is a staple ingredient that adds depth and umami flavor to dishes. However, there are instances where a substitute might be necessary. For those who follow a vegan or vegetarian diet, traditional fish sauce is off-limits due to its animal-derived ingredients.
Similarly, individuals with fish allergies will need to find an alternative to ensure their safety while cooking. And let’s not forget about the occasional mistake – we’ve all been there when we realize we’re out of a crucial ingredient at the last minute! In recognition of these scenarios, I’ve compiled a list of 10 reliable fish sauce substitutes that can help you achieve similar flavors and textures in your dishes, no matter what the circumstances.
What is Fish Sauce?
Fish sauce is an integral component in various Asian cuisines, particularly in Thai and Vietnamese cooking traditions. This condiment is a complex blend of fermented fish, shellfish, and salt, which yields a distinctive flavor profile that’s both bold and pungent. While its strong fishy aroma may not be appealing to everyone, the harmonious balance of ingredients effectively tames the fishiness, making it enjoyable for those who appreciate the ocean’s bounty.
For fans of seafood, this savory condiment is a must-have; conversely, even those who don’t typically enjoy fish or shellfish might develop an appreciation for its unique characteristics.
The Best Fish Sauce Substitutes

When seeking alternatives to fish sauce, I’ve discovered a range of options that can elevate your dishes just as well. Here are ten of my go-to substitutes, each offering unique flavors and textures worth exploring. Try one out on your next culinary adventure!
Soy Sauce

Soy sauce is often substituted for fish sauce due to two primary reasons: its ease of use in a one-to-one ratio and its widespread availability. The majority of people have a spare bottle of soy sauce lying around, making it a convenient replacement when fish sauce runs out. While soy sauce can be used as a substitute, it lacks the complexity and distinct flavor that fish sauce provides. However, it still works well in dishes like noodle recipes, fried rice, and stir-fries.
When using soy sauce as a main ingredient, you may miss out on the unique ‘fishiness’ that defines fish sauce. To compensate for this, you can try adding anchovies to the dish along with soy sauce. For every tablespoon of soy sauce, use one minced anchovy to achieve a fair representation of fish sauce’s flavor. In this case, the soy sauce can be used in a one-to-one ratio with the anchovies.
Tamari Sauce

While tamari and soy sauce share many similarities, there’s a key difference: tamari is often gluten-free. This makes it a great option for those with dietary restrictions. Tamari also tends to be richer, earthier, and less salty than its soy-based counterpart. When substituting tamari for fish sauce, you can use the same ratio – one-to-one – but consider adding a pinch of salt to balance out the flavors.
If you’re looking to amplify the umami flavor, try combining tamari with anchovies or rice vinegar (for a vegan or vegetarian option). It’s essential to note that not all tamari brands are gluten-free, so be sure to check the label before using it in your recipe.
Oyster Sauce

If you’ve ruled out the fish in the sauce as the issue, you’re in luck. Oyster sauce is an excellent substitute for fish sauce, and it’s often preferred due to its rich flavor profile. You can make a direct substitution using a 1:1 ratio, making it ideal for stir-fry dishes. However, its versatility allows it to be used in any recipe that calls for fish sauce.
So, what sets oyster sauce apart from its counterpart?
One notable difference is the presence of sugar, which gives oyster sauce its characteristic sweet and salty flavor. Additionally, oyster sauce tends to have a thicker consistency than fish sauce. To address these differences, adding a small amount of water can help thin the sauce and balance out the sweetness.
Worcestershire Sauce

When considering substituting Worcestershire sauce for fish sauce, the initial reaction might be skepticism. However, when you delve into its composition, the connection becomes clear. This common condiment shares a similar flavor profile with fish sauce due to its fermented fish and anchovy components. In fact, both share a salty, savory taste. The revelation that Worcestershire sauce uses fermented fish as a key ingredient might surprise some, but it’s true.
With all these similarities in mind, using Worcestershire sauce as a 1:1 replacement for fish sauce is a viable option. Its unique flavor profile makes it an acceptable substitute, and most people won’t be able to detect the difference.
Hoisin Sauce

While some individuals may substitute Hoison sauce for fish sauce, I find that it doesn’t quite replicate the desired effect when used alone. The thick, sweet profile of Hoison sauce can be overpowering. However, when combined with soy sauce, a game-changer is born. For instance, if a recipe calls for half a cup of fish sauce, I’d mix in a quarter cup of Hoison and a quarter cup of soy.
This harmonious blend yields the same level of saltiness and umami flavor as traditional fish sauce, while effectively tempering the sweetness of Hoison sauce.
Coconut Aminos

While many advocate for a one-to-one substitution of coconut aminos for fish sauce, I believe there’s room for nuance. In my experience, a more effective ratio is three-quarters coconut aminos to one part fish sauce, with the added depth of a pinch of soy sauce. This blend not only replicates the umami flavor of traditional fish sauce but also introduces a hint of sweetness.
For those looking for a gluten-free, soy-free, and vegan-friendly alternative, coconut aminos tick all the boxes – provided you opt out of adding soy sauce, that is. With this versatile ingredient on hand, cooks can confidently cater to a wide range of dietary requirements.
Fish Broth

While the unique flavor of fish sauce is undoubtedly a consideration, its role in recipes can be substituted to a certain extent with fish broth. To make this substitution work, you’ll want to use it in a 1:1 ratio with your original recipe. However, keep in mind that fish broth may not provide the same level of umami flavor as fish sauce, so some adjustments may be necessary.
One potential solution is to add a thickening agent like cornstarch, adding small amounts at a time until you reach the desired consistency. Additionally, you may need to adjust the seasoning by adding a pinch more salt to balance out the flavors.
Seaweed

While seaweed is often associated with sushi and sandwich wraps, it’s also an excellent vegan-friendly alternative to fish sauce. Its natural, allergy-free properties make it a great option for those looking for a plant-based substitute. However, converting seaweed to a liquid replacement can be tricky due to its solid nature. Fish sauce is typically used in larger quantities than seaweed, making the conversion rate challenging to determine.
Rather than offering a specific ratio, I recommend adding seaweed to your dish gradually and tasting frequently until you achieve the desired flavor. This approach allows for a more nuanced understanding of how much seaweed suits your taste buds. Keep in mind that seaweed has a stronger umami flavor profile compared to fish sauce, so it’s essential to start with half the intended amount. Trust me when I say that seaweed is potent – use it sparingly and adjust to taste.
Liquid Aminos

A vegan alternative to fish sauce that’s also gluten-free is liquid aminos. While they contain soy and salt, similar to fish sauce, they lack its umami depth. To compensate, you can use the same technique as adding anchovies, adjusting to taste if you’re not opposed to incorporating meat into your dish. When substituting, maintain a one-to-one ratio: simply add an anchovy filet for every tablespoon of liquid aminos, and adjust accordingly.
Vegan Fish Sauce

In no time at all, you can whip up your own vegan fish sauce using a variety of ingredients. For instance, you could combine soy sauce, tamari sauce, shiitake mushrooms, and seaweed to create a unique flavor profile. If you’re short on time, you can also purchase it online or find it in some grocery stores, although the selection might be limited. When you have your homemade fish sauce ready, simply use it as a one-to-one substitute for traditional fish sauce in your recipes.
