Dashi is what gives the amazing “umami” flavor to Japanese dishes and is a class of soup and cooking stock used in Japanese cuisine. As you can imagine, it’s often used in Japanese dishes.

As a fan of Japanese food, you cook it quite often. But you’ve realized: I don’t have dashi! What to do?!

Don’t worry, I’ve got you covered. You can actually make dashi at home with a few simple ingredients, and that’s also the most common and authentic form of dashi you’ll find anywhere else in Japan or abroad.

You can also use one of these 5 secret substitutes instead! Or if you’re not feeling up to it just yet, just buy some of my favorite instant dashi here now!

5 Dashi Stock Substitutes

To name a few of my favorite dishes, takoyaki and okonomiyaki are grilled foods that use dashi to form their tasty batter, which is made of flour.

As I’ve mentioned above, you can actually make dashi at home with a few simple ingredients, and that’s also the most common and authentic form of dashi you could make.

But if you’re a vegetarian, you might not want to. Or if you don’t have time to get the proper ingredients, you might not be able to.

In this video, I look at the best substitutes you can use. It’s definitely worth the time to watch it, as you’ll also get a lot of visuals on the types of thing you could use. Or you can read on if you just want to get down into some of your favorites!

What makes a good dashi substitute?

Dashi delivers umami and is made from kombu (seaweed) and katsuobushi (fermented fish), so you want a substitute that can deliver umami too. Chicken or white fish broths can, but a great vegan alternative would be to substitute the katsuobushi for shiitake mushrooms, another umami-rich Japanese ingredient, and keep the kombu.

Let’s get more into what dashi is and how you can use these substitutes in your dishes.

What is dashi?

Dashi is made by simmering kezuribushi (preserved, fermented skipjack tuna shavings, also known as katsuobushi) and kombu (edible kelp) in boiling water for 3 – 5 minutes. Then, it’s strained, leaving only the broth, which is called “dashi”.

Katsuobushi is dried, smoked bonito, which is a kind of tuna. Katsuobushi is often used as flakes shaved from a piece of dried fish.

This is actually kezuribushi, but we still call it katsuobushi.

You can actually buy the main ingredients katsuobushi and kombu on Amazon these days:

The high content of sodium inosinate in the katsuobushi and the glutamic acids in the kombu create a synergy of umami that’s very appealing to the taste buds on the tongue, which is why most people love it. Combining the flavors of katsuobushi and kombu in the broth unleashes the element of umami (one of the five basic tastes) into the dashi.

However, homemade dashi is no longer that popular these days. Even in Japan, it’s been replaced by granulated or liquid instant dashi since the end of WWII.

The added glutamates and ribonucleotides (which are chemical flavor enhancers in the instant dashi) are preferred by chefs since they have a stronger and less subtle flavor compared to homemade dashi.

I don’t make my own anymore and prefer to use this Ajinomoto – Hon Dashi for its rich flavor:

There are also other variations of dashi stock that include soaking shiitake, niboshi, or kelp in plain water for long hours to extract their flavors, or simmering them in hot water (70 – 80° Celsius) and then straining the broth that you get out of it.

Kikunae Ikeda, a chemistry professor at Tokyo Imperial University, discovered the unusual and strong flavor of kelp dashi in 1908 and identified it as the “fifth flavor” of the umami.

According to him, the glutamic acid found in the kelp in dashi stimulates a specific human taste receptor.

What is “umami” in dashi?

Umami is one of the five basic tastes that the human taste receptors react to and roughly translates as “pleasant savory taste”. It’s one of these five taste types:

It’s been described as savory and is characteristic of broths and cooked meats.

Believe it or not, until dashi was invented, scientists didn’t know that humans had a specific taste receptor that reacts to the glutamate in dashi!

In essence Professor, Kikunae Ikeda discovered both umami and the glutamic taste receptor in the tongue. It was also Professor Ikeda that coined the term.

5 best dashi substitutes

When you don’t live in Japan or in Asia, it can be a bit irritating to know that there aren’t a lot of Asian (or more precisely, Japanese) stores that sell instant dashi, or kelp or shavings of fermented skipjack tuna for that matter.

If you’re a fan of Japanese foods like miso soup, katsu don, sukiyaki, or oyakodon, then it might put you off because you won’t be able to cook your favorite Japanese meals.

Although you can actually order instant dashi online, it may take a few days before it arrives. Still, it’s a good way to store as much dashi as possible in the cupboard for all your future Japanese delicacies because you can use it in a lot of them!

Don’t fret in the meantime, because there are actually alternatives to dashi broth and you running out of it is the perfect time to try out dashi variants and replacements!

It may not be to your liking when trying out these alternatives for the very first time, especially since you’re accustomed to the taste of regular dashi. But in time, you’ll find that the varying flavors are also good in and of themselves.

Even though the substitutes may not be picked up by the taste receptors that are specifically tuned to umami (glutamic acids), they can still be the next best thing and you might even prefer to use one of these substitutes when you’re trying to stick to a vegan diet.

Here are the 5 best alternatives to dashi!

5 Best Alternative to Dashi

1. White meat fishes in dashi

Going by Japanese tradition, the washoku (和食) or Japanese cooking, they’d originally intended for dashi to be made from fish or seafood broth.

If you’re going to make a dashi replacement, then you’ll need mild, non-oily, white meat fishes, such as the tilefish, bass, halibut, snapper, and cod.

Don’t use tuna or mackerel, as these types of fish have a stronger fish flavor and might dominate the overall flavor of the dish that you’re preparing.

Take note that dashi is just a flavor agent and while it gives the perfect taste to the meal, it doesn’t overtake the main flavor in any way.

In order to get started, you’re going to need to get the parts of the fish that people don’t normally eat, like the head and bones (you may also need a few pounds of meat). These meat scraps are actually free in the fish market, so you don’t necessarily need to spend money on this trip.

Once you’ve acquired the parts you need, then wash them thoroughly and make sure no traces of blood remain on them, as they’ll turn the broth into a bitter juice.

Fumet is what you call fish stock. At the most basic level, it's comparable to dashi, as the seafood taste is rooted deep within it.

2. Shellfish dashi replacement

Homemade Shellfish Dashi stock

For this dashi substitute recipe, you’ll need to use shellfish scraps instead of fish. But prawns and shrimp create a better taste for this type of dashi than shellfish, so you may want to put more emphasis on shrimp.

3. Vegetable vegan dashi recipe

Homemade Vegan Dashi broth recipe

If you’re a vegetarian or you plan to cook for people who are on a vegan diet, then the vegetable seaweed and mushrooms (kombu and shiitake) dashi alternative would be a great option to try.

How to make a vegan dashi broth:

Unlike the kombu, however, you can reuse the mushrooms up to 10 times before throwing them away! So that means you can make a lot of mushroom dashi substitute.

Place the mushrooms in a plastic bag and put them in the freezer for future use.

Now, you can’t get shiitake mushrooms everywhere. But fortunately, Amazon ships these dried shiitake mushrooms so you can use those in your stock:

How to make vegan vegetable dashi stock recipe

Other vegetables that are also good to make dashi from are sundried daikon and sundried carrot peelings. These vegetables contain basal umami (free glutamate), which is a good dashi alternative.

If you wish to experiment further with other vegetables and herbs to make a dashi substitute, then visit the Umami Information Center for more details.

4. Chicken broth dashi substitute

Chicken broth is easier to make, as chicken meat is widely available and all the other ingredients needed to make it are very accessible too!

How to make chicken dashi stock:

Ingredients:

Cooking instructions:

  1. Turn on the stove to medium-high heat. Set a large cooking pot over it and put all the aromatic ingredients in it (4 quarts of cold water, salt, thyme, parsley, garlic, onion, carrots, celery, and chicken). Bring to boil for about 30 minutes and then reduce the temperature to medium-low, cover with the lid, and simmer for 2 hours until the chicken falls apart. Skim the foam from the surface as it builds up.
  2. Strain the broth through a large sieve or colander into a large bowl. Once cooled, take a big sieve and strain the broth into a large bowl. Using a wooden spoon, press the mixture as much as possible to get all of the broth.
  3. Pour the broth into 4 pint glass jars, cover them with lids, and refrigerate overnight. Now you’ll have lots of chicken dashi stock in the reserves to use for all your future recipes that may require it.

5. Powdered or cubed broth dashi substitute

Cubed and powdered broths are probably the easiest way to make dashi stock and while you may use chicken, fish, or shrimp flavors, you should never use pork or beef cube or powdered broth, as they won’t accentuate the taste of your dish, but instead, overpower it.

Salt, monosodium glutamate, hydrolyzed soy/corn/wheat gluten protein, hydrogenated cottonseed oil, beef fat, and many more are just some of the ingredients in a beef broth cube.

Too much beef fat and MSG (monosodium glutamate) give the broth cube its strong flavor, but even natural beef broth extracted from fresh cow’s meat still has the same effect.

So it’s best to steer clear of those and pork flavored cubes altogether.

Dashi substitutes for some of your favorite Japanese dishes

Technically, all the ingredients for homemade dashi are easily accessible in Japanese and most Asian grocery stores. However, there may be times when they too will run out of stock or the new ones they’ve ordered haven’t arrived yet.

Fortunately for you, the dashi replacements discussed above should come in handy for situations such as these, especially if you can’t wait for the original ingredients used for dashi to become available anytime soon.

Below are some of the delicious recipes you can prepare with any of the dashi stock alternatives mentioned above.

FAQs about dashi

Here, I answer some of the most common questions around dashi that I didn”t get around to answering in the main post!

Is dashi the same as fish sauce?

While there’s fish in dashi, it’s not the same as fish sauce.

Fish sauce is often made from anchovies, salt, and water, and has a strong salty taste. Dashi is made from seaweed (kombu) and fermented dried tuna (bonito flakes).

Is dashi the same as bonito flakes?

Dashi is not the same as bonito flakes. Rather, bonito flakes are one of the ingredients to making dashi, next to dried seaweed (kombu).

Is dashi the same as miso?

Miso is not the same as dashi, though they’re both used to make miso soup. Dashi is a broth made from dried fermented tuna and dried sheets of seaweed and miso is a paste made from fermented soybeans.

What can I substitute for bonito flakes?

To get the bonito flavor, you can substitute them with some shellfish, preferably shrimp or prawns. A vegan option could be shiitake mushrooms to add umami to your dish.

How long does dashi last in the fridge?

You don’t have to use all of your dashi at once, right after you’ve made it. You can save dashi in a closed container but you have to put it in the fridge. It’ll keep for around 7 days or you can keep it in the freezer, where it’ll last 3 weeks.

Is dashi kosher?

Normally no, as the bonito flakes are made of dried tuna. And while tuna is a fish that can be used in a kosher kitchen, the dried bonito flakes that are used in dashi aren’t certified kosher.

And since it’s very hard to make that yourself, and the shrimp or prawn substitute won’t do, you can make it with the grilled skin of whitefish for flavor.

Can you buy dashi at the grocery store?

Unfortunately, you can’t buy Dashi at the normal grocery store. Even most Asian grocery stores don’t sell it! However, you can purchase dashi from most Japanese stores and a wide variety of online stores that deliver across America.

You can buy Hon dashi stock, which is great:

Enjoy Japanese dishes, even if you’ve run out of dashi stock

It’s true that Japanese cooking uses a lot of dashi stock. But just because you’ve run out of it doesn’t mean you have to go without!

With these handy substitutes, you’ll be able to whip up some Japanese food, all without losing too much of the dishes’ authenticity.
