Vegan Fish Sauce: Simple Asian-Inspired Magic in a Bottle!

I was trapped in a broccoli forest the other day — bear with me here—when it dawned on me how complex the whole “going green” thing can be. I mean, kudos to those plant-lovin’ vegans out there; making the universe a healthier place and all that jazz. But like with any good superhero story, there’s always a flip side. The diet can be super unrealistic for some of us, especially those juggling chronic illnesses. So, let’s dial down the self-righteousness, can we?

I have to admit, the carbon footprint that comes from shipping heaps of watermelon to wintry New York is extra AF. And don’t even get me started on the veggie-geddon that can happen when large-scale vegetable farming gets a little out of control. Sometimes I just wanna scream, “Chill, sweet carrots, not everyone can get their cabbage feast all year long!”

Aaaand speaking of uncharted territory, I’ve brewed up this finger-lickin’ vegan fish sauce that, legit, will have you reaching for seconds. Don’t worry, this bad boy swaps fishy fish for a plant-based twist that won’t have Nemo swimming in circles. So, even if we can’t all be full-time members of the Young Avengers or the International Left-Hander Society (yes, that exists), let’s at least get saucy together while exploring the greener side of culinary delights!


  1. Shiitake mushrooms – Rich, smoky flavor that gives depth of umami flavor. Great source of Vitamin D.

  2. Tamari – A type of soy sauce, adds a subtle saltiness to the sauce.

  3. Wakame seaweed – Unique briny flavor, loaded with minerals and antioxidants.

  4. Chickpea miso – Fermented soybean paste that gives the sauce its fishy flavor.

  5. Garlic – Adds a nice kick of flavor and has health benefits.

  6. Water – To make the sauce, good-quality water is recommended for the best flavor.


  1. First thing’s first, chop up the mushrooms.
  2. Grab your saucepan and toss in the water, sliced mushrooms, seaweed, garlic cloves, tamari, and miso.
  3. Bring everything to a boil and then let it simmer for about 15-20 minutes.
  4. Let the sauce cool down to room temperature before straining it into a jar or other airtight container. Optional: If you want an extra boost of flavor, let the sauce sit overnight before straining.
