Oyster Sauce is a common ingredient in many Asian dishes, but I have never seen a vegan version of the sauce available at the store (there does seem to be some available online, but contains additives and very expensive!) It’s very easy to make a healthy version at home with whole ingredients that you can use in your favorite dishes, or even as a dipping sauce if desired.
This isn’t a pretty sauce to photograph though!

All you need to do to make this sauce is blend the ingredients in a food processor (or blender if you want a smoother sauce), and then reduce it on the stove top. It is easy to make, but does take some time as you do need to reduce a lot of liquid to get the strong flavor profile. Because it takes a long time on the stovetop, I usually make a double or triple batch and freeze portions for later. It’s such a versatile sauce you will be able to use it in a bunch of different recipes!
When it’s near fully reduced, the sauce will look somewhat like this. The color will vary a bit depending on the type of broth and mushrooms you choose.


Vegan Mushroom “Oyster” Sauce
Ingredients
- 1.5 cups mushrooms Sliced. Use fresh or rehydrate dried mushrooms.
- 1 cup vegetable broth Use mushroom broth and low or no sodium broth if available.
- 2 Tbsp tahini Optional but recommended. See notes.
- 3 cloves garlic
- 2 Tbsp ginger Peeled and diced into chunks.
- 2 Tbsp tamari
- 1 Tbsp miso paste Use white miso if available.
- 2 tsp maple syrup
- 1 1/2 tsp five spice powder
- sesame flavoring Optional, see notes.
Instructions
- Add all ingredients to a food processor, process until somewhat smooth.
- Bring to a boil in pan on stovetop on high heat. Reduce to medium heat, and reduce sauce until it is thick and pasty. See photo. This could take 30-60 minutes depending on pan/heat.
- Refrigerate in an airtight container, or freeze anything you won't use in a week or so.
Notes
This sauce is what I’m using in my Drunken Noodles recipe (available on the site soon!). You will only use a portion of the sauce, so you will have leftovers to use with different dishes. You can freeze this sauce to use later if you want.

This is really good! Tons of flavor.
I just discovered your wonderful site today and I’ve saved a bunch of recipes already. Excellent mushrooms!
Thank you for sharing such a blog!
