Quick Dashi Recipe - Japanese Soup Stock (2024)

Ichiban Dashi (number one dashi) is the backbone of Japanese cuisine. Dashi brings the umami richness through lightly simmered kombu and bonito flakes. Ready in 30 minutes, this quick soup stock is a Japanese household staple to take your hot pots and soups to the next level!

Why We Love This

Dashi is the key ingredient to Japanese cuisine! It brings that classic umami flavour without tasting fishy.

It’s so simple to make fresh dashi stock at home and much healthier and commercial dashi stock powder too. Made with natural ingredients – no fake flavour enhancers here! – it’s easy to adapt to your preference too. Soak the kelp for a shorter time to get cooking faster, or soak it longer to bring out a deeper, richer flavour.

You can even use the leftover kelp and bonito flakes to make your own rice seasoning (furikake), so everything is used and there’s no food waste.

What is Dashi?

Dashi is a popular variety of Japanese soup stocks, with the most commonly used being Ichiban Dashi / Awase Dashi – a three ingredient dashi made from water, katsuobushi and kombu.

You’ll find dashi in Japan’s most famous dishes, including takoyaki, okonomiyaki, shabu shabu and nikujaga. You can even use it as a simple stock for onsen tamago (hot spring eggs).

What is Dashi Powder?

In many places it can be hard to track down the ingredients to make fresh dashi from scratch, which is where dashi powder is becoming very popular to use instead. Dashi powder is great when you’re short on time, travelling or camping, or can’t get the ingredients. It’s now widely found in most big supermarkets or Asian grocers.

We use a ratio of 1 tsp of dashi powder for every cup of water (250ml / 8.45fl oz), but some people prefer a milder flavour and in that case use only 1/2 tsp of dashi per cup.

For those that haven’t used it before, it’s very similar to reaching for the chicken or vegetable stock powder in Western cuisines.

Dashi Variations

• Ichiban Dashi / Awase Dashi – Full strength dashi made from katsuobushi and kombu. This is the recipe we’re sharing today, and one of the most popular used in Japan!
• Niban Dashi – A half strength dashi made from the leftovers of ichiban dashi, sometimes made by adding a little more fresh katsuobushi for extra flavour. Mostly used for miso soup, but you could also use it in zosui rice soup.
• Kombu Dashi – This is the vegan and vegetarian friendly version that uses only kelp / kombu and omits the katsuobushi.
• Shiitake Dashi – Made with shiitake mushrooms, this is also vegan and vegetarian friendly.
• Katusobushi Dashi – Made with katsuobushi only – no kombu!
• Iriko / Niboshi Dashi – Made with sardines or anchovies, this is more commonly found in Korean based dishes and called dasima in Korean.

Where We Learned This

We were lucky enough to learn about dashi from quite a few friends and acquaintances we met along our many trips through Japan. Two that stand out to us are from one of our “Osaka Mums”, Yoshiko, who teaches homestyle Japanese cooking, and the other is from a chef in Okayama who was taught by her grandmother. Both styles taught us so many tips for the perfect dashi broth that we can’t wait to share with you!

How to Make Ichiban Dashi at Home:

1. Using scissors, cut 1-2cm / ½ inch slits along the sides of thekombuto open up the flavour.
2. Pour thewaterinto a medium saucepan and add thekombu. Allow to soak for 15 minutes for a quick dashi, or overnight for a rich dashi stock.
3. Place the saucepan over a low-medium heat, and once you see small bubbles start to form on the bottom of the pan (around 5-10 minutes), remove thekombu.

4. Pour thebonito flakesinto the water, but don’t stir, just lightly press with chopsticks or a spoon to make sure they’re all submerged. Simmer gently for a minute before switching off the heat. Stand for a few minutes and allow the flavours to bloom.
5. Place a colander and paper towel or cloth over a medium bowl and slowly strain the dashi through, catching the bonito flakes in the colander.Alternatively, allow the bonito flakes to sink to the bottom, and carefully ladle out the liquid dashi stock.
6. Use immediately or store in the fridge in an airtight container for 2-3 days or in the freezer for 1-2 months.

Ichiban Dashi vs Niban Dashi

Ichiban Dashi means “first stock”, it is the strongest dashi stock and what is used in most Japanese recipes that call for dashi stock.

Niban Dashi means “second stock”, it is a weaker dashi stock made from the leftover kombu (kelp) and katsuobushi (bonito flakes). This second stock is mainly used for making miso soup.

If you want to make niban dashi after making ichiban dashi, the steps are simple!

Making Niban Dashi

Place the used kombu and katsuobushi back into the medium saucepan and add 4 cups of spring water / filtered water.

Heat over a medium heat for 5-6 minutes, bringing it to a gentle simmer with small bubbles on the bottom of the pan (just under boiling). Add 15g of new katsuobushi and continue to simmer for a minute before switching the heat off.

Allow to cool and steep for a few minutes, then strain and use straight away or store in an airtight container.

Wandercook’s Tips

• Cooked Kombu – Once the kombu / kelp is cooked, you’ll notice it’s quite slimy and slippery when you go to remove it, this is completely normal.
