Vegan Dashi with Kombu and Dried Shiitake
Japanese Dashi is typically made with fish, like bonito flakes—but if you’re looking for a plant-based alternative, this vegan dashi is perfect. Just soak kombu and dried shiitake mushrooms in water and let the umami-rich flavors develop. It’s super easy, so give it a try!

Vegan Dashi with Kombu and Dried Shiitake

Equipment
Ingredients
Instructions
- Combine Ingredients: Place the dried shiitake mushrooms and kombu in a glass jar or container. Pour in the water to cover.
- Refrigerate: Place in the fridge for at least 5 hours, or overnight for a deeper, richer flavor.
- Strain the Dashi: Once the liquid turns a light golden brown, remove the shiitake and kombu. Your vegan dashi is ready to use in soups, simmered dishes, or rice recipes.
Notes
- Storage: You can store the dashi in the refrigerator for up to 3 days. For longer storage, freeze it for up to 1 month. Using an ice cube tray makes it easy to portion and use as needed.
- Be sure to remove the kombu after the dashi is made — if left in the liquid for too long, it can turn slimy.
- The soaked kombu and shiitake are packed with flavor. Slice them up and use them in miso soup, takikomi gohan (seasoned rice), furikake, or stir-fries.

I love this home made dashi! It’s pure and simple, easy to make, and there are no hidden additives. It is the perfect base for soups with the dried shiitake & seaweed giving such a wonderfully rich umami flavor. Kombu is not readily available here, so I use wakame.
This stock is perfect to keep in the fridge as a meal prep ingredient. Now making soup couldn’t be easier! Thank you Juri.
