Cozy up with a piping hot bowl of hearty Miso Soup with Yuzu Kosho. Japanese citrus pepper paste adds a refreshing, spicy kick and pairs wonderfully with this soup packed with pork belly and vegetables. {Vegan adaptable}

Miso soup served into a soup bowl from a donabe clay pot.

Soups are ideal for serving nutrient-dense foods that nourish our bodies. That is why the Japanese drink a warm bowl of miso soup almost every single day. There are many versions of miso soup one can make at home, but this Miso Soup with Yuzu Kosho is everything my family and I desire for dinner at home. Simmered in a dashi broth, it’s deliciously layered with pork belly, shiitake mushrooms, sweet cabbage, carrots, leek, and tofu, and lightly spiced with a very special condiment – yuzu kosho.

Miso Soup with Yuzu Kosho

I remember vividly when I first tried miso soup that was flavored with yuzu kosho. It was at a breakfast setting at a Japanese ryokan in Kurokawa Onsen, Kyushu (read here). The lady who served our hot breakfast told me to add in yuzu kosho to the miso soup. I thought I’ve heard her wrong and found myself repeating after her “yuzu kosho in miso soup?”, but only with a highly dubious face. She smiled and gave me some reaffirmation nods.

Now, while I enjoy using yuzu kosho to season meat or to flavor yakitori and other dishes, I’ve never heard of seasoning miso soup with yuzu kosho. Curiously, I took the lady’s advice and gave it a try. I first drank the miso soup as it was, and it was delicious, then I added a tiny bit of yuzu kosho to my soup and drank it again. Wow…I was blown away instantly!

Watching my deep satisfaction, Mr. JOC followed suit and added some yuzu kosho into his miso soup. Needless to say, he too was taken by how insanely delicious this little pepper paste did to the soup. We both happily drank up our soup and asked for okawari (second serving). The lady was so happy to see how amazed we were and she kept asking if we want another okawari.

Citrusy, slightly spicy, slightly salty but incredibly aromatic, who would have thought this condiment can add so much more punch to the everyday soup that I’ve been drinking all my life. I would never forget my first taste. Since we returned home to the States, we’ve been enjoying our miso soup with yuzu kosho frequently and we’ve been telling our friends and family about this little new discovery, and I would love for you to try it too.

What’s Yuzu Kosho?

Yuzu kosho is still a relatively unknown condiment to most outside of Japan, but when I was recently Google Trends searching Yuzu Kosho, I was surprised to see it actually has a higher result than the direct translation of “yuzu pepper”. I think many Japanese restaurants are using Yuzu Kosho on their menus these days, and many customers are probably searching it on their phone while trying to decide what to order.

So what is yuzu kosho? Yuzu is a winter citrus that’s used in Japanese cooking. It has a flavor somewhere between a lemon, mandarin orange, and grapefruit! It looks like this, and I have used this citrus to make Yuzu Sorbet. Yuzu kosho is simply a paste made from chili peppers, yuzu peel (when it’s still green), and salt. It is then allowed to ferment to bring out the flavors even stronger.

The best yuzu kosho is the one pictured above. It comes in a jar and costs about $8-9. You can find it in the spice aisle (where they carry wasabi, karashi mustard, shichimi togarashi, etc) at Japanese grocery stores. You can also find a different brands on Amazon.

Substitutions and Variations

Miso soup is all about customization. If you couldn’t find thinly sliced pork belly, that’s okay. You can leave it out. Just know that pork belly is not bacon; it’s the same cut as bacon but it is fresh/raw and not cured like bacon. Not a fan of mushrooms or tofu? That’s okay too.

You can make a vegetarian/vegan version with kombu dashi (just leave out katsuobushi) and add in lots of vegetables. You can add pretty much any vegetable in your miso soup, even though they may not be the typical Japanese options. If you only have kale in your hands, of course, you can throw in some kale in your miso soup. Just because we don’t use kale in Japanese food, it doesn’t mean we can’t have miso soup with kale.

If you’re not sure with your selection of vegetables, leave a comment below and I’ll see if it’s a good match.

Whether you’re making regular or vegetarian miso soup, you must use dashi for the soup broth. Do not substitute with chicken broth or water because dashi is the only ingredient that makes miso soup taste authentically Japanese.

If you love miso soup, I hope I’ve convinced you to add a jar of yuzu kosho to your pantry so you can have your miso soup with this amazing pepper paste. The spicy, citrusy and aromatic flavors of the condiment really do the trick to elevate the bowl of soup and everything just taste a whole lot more delicious.

    Miso Soup with Yuzu Kosho Ingredients

To Start the Dashi

  • In a measuring cup (or a large pot), add 4 cups water and 1 piece kombu (dried kelp). Let it steep overnight (if possible) or as soon as you start preparing this dish. This is kombu dashi or Vegan DashiTip: Alternatively, you can make dashi with dashi powder or a dashi packet.

To Finish the Dashi

  • Transfer the vegan kombu dashi to a soup pot or donabe. Slowly bring the kombu dashi to a boil over medium-low heat. When the water is almost boiling, remove the kombu to avoid sliminess. If you are vegan/vegetarian, skip the next two steps.

  • Add 3 cups katsuobushi (dried bonito flakes) and cook for 15 seconds. Then, turn off the heat and let the katsuobushi steep in the pot for 15 minutes.

To Cook the Miso Soup

  • Meanwhile, in a separate large pot (or donabe), heat 1 Tbsp toasted sesame oil over medium heat. Once the pot is hot, add the pork belly and stir to cook.

  • Once the pork belly is 80% cooked through, add 1 Tbsp sake and stir to combine. Then, add the chopped leeks.

  • Once the leeks are wilted, add the rest of the vegetables and mushrooms. Stir to coat with the oil. Using a fine-mesh strainer, strain the dashi into the pot (or add the dashi you made with dashi powder or a dashi packet).
    Miso Soup with Yuzu Kosho 11
  • Bring the soup mixture to a boil, skimming the foam and scum from the surface while cooking. Turn off the heat. Add half of the 4 Tbsp miso first, and then gradually add in more as you taste the soup. Each brand and type of miso tastes different and the sodium level varies, so you want to taste the soup before adding more miso.
    Miso Soup with Yuzu Kosho 12
  • To the soup, add 14 oz soft/silken tofu (kinugoshi dofu), cut into cubes. Turn on the heat to continue to simmer until the tofu is warm (tofu is edible chilled, so you don’t have to worry about “cooking” it). Do not let the miso soup boil. It should take no more than 3–4 minutes to warm the tofu. The soup is now ready.

To Serve

  • Before serving, scoop out a small portion of yuzu kosho (Japanese citrus chili paste) from the jar and place it on a small plate. Grind 2 Tbsp toasted white sesame seeds and put it in a small bowl. Serve them alongside the soup pot or donabe. After you ladle the soup into individual serving bowls, add a pinch of Yuzu Kosho, sprinkle some sesame seeds, stir in, and enjoy!

  • You can keep the leftovers in an airtight container and store in the refrigerator for up to 3 days and in the freezer for 2 weeks.

Love making this chunky miso soup! so hearty! my husband loves it too! never tried adding meat to a miso soup! Your video is a winner too! Thank you so much!5 stars

Hi,just made this dish.It was delicious,except I didn’t have yuzu koshu.I think I overcooked the pork belly.I will get the yuzu kosho.There is a Japanese store next to my job.Tomorrow I will cook pan fried ginger pork belly.Thanks for your recipes.5 stars

Nami,

First of all, your recipes ROCK!! I have tried many with pleasant results.
Now, are you using red or green yuzu kosho? I assume green (in picture). I use the green (just a touch) in the karaage marinade – nice spicy touch! I am a bento fan for work lunches. they are quite healthy and impress my co-workers. Its just an easy to make lunch for me.
Thanks for all the great recipes and meals.

I’m drooling! I’m totally a soup-a-holic and this sounds amazing. I’ve heard of yuzu before but not this paste. I can imagine it would work so well in the soup.

it’s overcast and raining here on Guam so I made this special miso soup. It is so delicious, hearty and perfect for this type of weather.
Thank you, Nami for sharing this amazingly delicious recipe!

Thank you!!! This was so good, that I made it twice last month. There is something very grounding about the flavors and textures in this recipe, especially on cold winter evenings. And thanks for introducing me to yuzu kosho. It really gives the broth a nice, warm depth (just a teenie bit goes a long way). I can’t believe I had never heard of it before. I didn’t use the pork belly, but used shabu shabu slices of pork in its place. It was just right for me. Can’t wait to make it again.

Hi Nami,

If I am using instant dashi (by adding dashi powder to water), how many cups of it will I need for this recipe? Thanks!

Can’t wait to try this recipe. My hubby excitedly went to buy the yuzu kosho after reading about it!

thank you. great recipes and teaching techniques.

Bless you!

Hi Nami, I made this miso soup with yuzu kosho last night with mixed results. The broth was wonderful, as were the veggies. I think I might have added a little too much yuzu kosho to my bowl, but I did get a sense of its essence and the citrusy umami flavor it added to the dish. My problem was with the pork belly. I have made a couple of your other recipes with pork belly in the past with great success. Unfortunately, last night it turned out really tough and although I’m sure the fat added some great flavor, my husband and I both found ourselves picking it out of our soup after getting a fatty mouthful once or twice. Do you have any tips? Maybe I sliced it too thick or the wrong direction? Was I supposed to put all of the fat into the soup after cooking it? Any suggestions would be welcome.

Thanks as always for the wonderful recipes. They remind me of the home cooking I experienced when I lived with a host family in Japan during high school for two years. I bought a donabe pot a few years ago and look for any chance to use it. Last night’s dinner was a great opportunity to pull it out again.

You’re just showing off with your gigantic suribachi. Now my wife wants a bigger one as well 🙂
How come you don’t use a miso strainer like this one https://www.amazon.com/Oxo-Stainless-Steel-Miso-Strainer/dp/B0001BDD20 Its a bit easier since you can hang it on the edge of the pot.

Great recipe by the way. Your website is the best.

I have been following your instagram and blog for nearly two years and so far, this miso soup is my favorite — your video made it look delicious and so simple to prepare (it was both). I added extra cabbage because I didn’t have any carrots, and it tasted so good. I also did not have the yuzu kosho paste, but I used the yuzu kosho hot sauce from Trader Joes — which was fine, but I’m looking forward to trying it with the yuzu kosho paste. It was satisfying and made a great meal during our extended winter on the east coast. Thank you for all of your wonderful recipes.

Hello Nami
Thank.you for sharing this recipe about yuzu kosho
Recently i went to Donki.They sell yuzu kosho for $3-4.It looks cheap.However other jap supermarkets sell.it for about $8-9 like the one u showed in the picture.Since there is a big difference in price, is there also a difference in quality?

Hi Nami… very special recipe ..very excite..
i want to ask you something…
what is the different about yuzu and lemon….. ???
and do you know … homemade yuzu kosho..
Best regards…

Thanks for this recipe Nami !! Although I do not think I can get yuzu kosho, I still find it interesting how a citrus fruit can combine with miso soup.
Also, these days I have seen several of your recipes and I have noticed that in some you simply mention dashi as an ingredient but in others you specify a quantity of water and katsuobushi to later do dashi. The latter has caused me curiosity and I would like to know why it is done this way.
Finally, if I can not find yuzu kosho, is there a substitute?
Finally, thanks for answering my comments in other post, I feel that I have become intense, I’m sorry
regards

Hi Nami! Do you think adding a bit of lemon rind to the broth could add a similar citrusy punch? In any case I will try and let you know! Best, Ana
