Making Japanese Kombu Dashi is a breeze! This plant-based broth lets you enjoy the unique, aromatic flavor without much effort. Learn how to make it and give your dishes that extra umami kick!
Soak the Kombu: Add water and kombu to a medium saucepan and soak for 30 minutes or more.
Make the Dashi: Heat the saucepan over medium heat and gradually bring the water to a simmer. Remove the kombu just before the water reaches a boil.
Use or Store: Use the kombu dashi immediately as a base for soups, stews, or sauces. Let the dashi cool to room temperature if storing, then transfer it to a clean glass jar.
Notes
Storage: Keep in a glass jar or airtight container and store in the fridge for 5 days or the freezer for one month.
Don't wash the kombu before using it. The white powder on the surface is an umami ingredient. If you wash it away, you will miss out on its deliciousness.
Avoid boiling the kombu for too long because the broth will become sticky and lose its taste.
Don't waste any leftover kombu! Transform them into delicious side dishes, furikake, and onigiri fillings. See the recipes above.
