How to Make Dashi (The Ultimate Guide) (2024)

This is the ultimate guide to Dashi, Japanese soup stock. You’ll learn about the different types of dashi, the ingredients, and how each stock is used in Japanese cooking.

What is Dashi?

Dashi (だし, 出汁) or Dashijiru (出し汁) is Japanese soup stock that is the backbone of many Japanese dishes. It is all-important and indispensable, and you can trace its existence in Japanese daily cooking back to the Edo period (17th Century).

Unlike soup stocks from other cuisines, which are typically made by boiling an assortment of meat, vegetables, herbs, and spices for several hours, dashi usually containsonly one or two ingredients, and preparation takes just 20 minutes. Yet, dashi gives Japanese food its unique, rich, umami-packed savory flavor.

The Japanese soup stock is often made from:

• Kombu(dried kelp)*
• Katsuobushi(dried bonito flakes)
• Irikoorniboshi(dried anchovies/sardines)
• Shiitake (dried shiitake mushrooms)*
• OR acombinationof all above or two (such as kombu + katsuobushi)

*vegetarian and vegan

How Does Dashi Taste Like?

All the dried ingredients that are used to make Japanese soup stock are rich in naturally occurring glutamates and provide intense flavor to the stock. Dashi creates a savory umami flavor from all these ingredients and you don’t need to season the food as much once you have a good stock.

With a distinctive sweet and savory note, the deep umami flavor is what set dashi apart from other stocks.

How Do You Use Dashi in Cooking?

The most common use for Japanese soup stock is in a bowl of delicious miso soup, the soup for the soul for the Japanese. If you wish to make a bowl of authentic Japanese miso soup, I strongly encourage you to use dashi instead of substituting it with other broths such as vegetable or chicken broth. You will notice the difference right away!

Dashi is also being used as abroth basein Japanese hot pots (e.g., Shabu Shabu), stews (e.g.,Oden), simmered dishes (e.g., Nikujaga), and noodle soup dishes (e.g., udon, soba, and ramen).

You can also use it as aseasoning liquid(e.g, Tamagoyaki,Takikomi Gohan, and Takoyaki) or add it to sauces to bring out the savory depth of the dishes. Since it is a clear umami-rich broth with a subtle aroma, dashi is really versatile and you can literally use it in any dish that call for a touch of liquid.

6 Different Types of Dashi

A lot of people think dashi is made of fish, so vegetarians and vegans can’t use it. No, that’s not true.

There are 5 different types of dashi and I’ll introduce them here. How do we decide which stock to use for a particular dish? Well,there is no rule and it’s up to you. Below, I added some examples of dishes that go well with each type of dashi.

Classic Awase Dashi (Kombu and Katsuo Dashi)

• Awase dashi (合わせだし) is a combination of kombu(dried kelp)andkatsuobushi(dried bonito flakes).
• The most common, all-purpose seafood-based stock (and this is my go-to stock).
• Awasemeans “combination” or “mixed” in Japanese.
• This is my go-to dashi for my recipes.

3 Ways to Make Dashi

Depending on your time and need, you can decide how to make Japanese soup stock using three ways. I’ll start from the most time-consuming method (but only 20 minutes!) to the instant method.

• Method 1: Make Dashi from Scratch (20 minutes)
• Method 2: Dashi Packet (5 minutes)
• Method 3: Dashi Powder (5 minutes)

Method 1: Make Dashi from Scratch

Once you decide what ingredient(s) you want to use for your dashi, please click the link to get the recipe.

1. Kombu(dried kelp)+katsuobushi(dried bonito flakes) →Awase Dashi
2. Kombu→Kombu Dashi
3. Katsuobushi→ Katsuo Dashi
4. Irikoorniboshi(dried anchovies/sardines)→Iriko Dashi
5. Dried shiitake mushrooms→Shiitake Dashi
6. Dried shiitake mushrooms + kombu → Vegan Dashi

If you are not sure, go with Awase Dashi. If you’re vegetarian/vegan, go with Vegan Dashi.

Method 2: Dashi Packet (Shortcut)

This is the most convenient method which produces pretty flavorful soup stock. One drawback is that these dashi packets might be hard to find in Asian grocery stores. Your local Japanese grocery stores should carry one or several brands.

The Dashi packet above is Japan’s most popularKayanoya Dashi Packet(MSG-free & additive-free; a bit pricy; Amazon).You may also find Yamaki Dashi Packet in Japanese grocery stores or onAmazon.

Method 3: Dashi Powder(Shortcut)

If you want to make a bowl of miso soup, instant dashi powder can be very convenient and save a lot of your time. The most commonly known products areHondashi (ほんだし) andDashinomoto (だしの素), which you can find in Asian or even American grocery stores.

However, I strongly recommendMSG-free & additive-free Dashi Powderthat’s available at Japanese grocery stores or Amazon.
