Why We Love This Recipe

  • This udon noodle soup recipe is so simple to make at home – all you need are a few basic Japanese ingredients: dashi powder, soy sauce, and mirin (sweet rice wine). Even better, these ingredients can also be used as the base for a wide range of essential Japanese dishes – our favourites are okonomiyaki savoury pancakes, onigiri rice balls and gyoza dumplings.
  • Udon noodles are a fantastic dish to slurp down when you’re in a rush. But we like to take our time a little more to appreciate the subtle flavours, and enjoy the differences of the dashi stock between restaurants, home made and powder form.
  • The great thing about this dish is the ability to make it as quick or a slow as you like, depending on how hands-on you want to be, and what toppings you’d like. While our Udon Noodle Soup Recipe uses only basic ingredients for a quick eat, below are some further ideas for beefing up your dish.

What You’ll Need

For our simple udon noodle soup recipe we opted to make our dashi stock with dashi powder. If you have time, you might like to make your own proper dashi stock base with kombu seaweed and bonito flakes. 

Optional Toppings

 

How To Make Udon Noodle Soup Recipe

  • Cook udon noodles according to packet directions, or recipe if you’re making them by hand.

Tips

  • For the best experience, use the freshest udon noodles you can source. Any noodles will do of course, but freshly made udon noodles have the most delicious chewy texture that you just can’t beat. Cook them until al dente, just like pasta, so they don’t become too soggy.

FAQs

What are Udon Noodles made from?

Udon noodles are made from a combination of wheat (normal regular white flour) and salt. That’s it! No egg or rice. Sometimes a little cornflour is used when the noodles are cut to stop them from sticking together.

How are Udon Noodles made?

We’re so glad you asked! This has to be the most fascinating part. Traditionally, udon noodles are actually made with your feet! Depending on the style, it’s not uncommon to press out the dough many times to ensure the ultra smooth texture of the final product.

During our previous trips to japan we’ve learnt a couple of different methods to make udon noodles from scratch. The first is Shikoku Mountain-style Udon and the second is Shoganji Temple Udon Noodles – made with fresh seawater for the perfect balance of salt.

What other toppings can you put on Udon Noodles?

The most simple udon noodle topping is a handful of sliced spring onion (scallions) with bonito flakes, but why stop there?

Try these other popular udon noodle toppings:

  • Fried tofu
  • Wakame (seaweed)
  • Tempura vegetables or prawns (shrimp)
  • Kamaboko – fish cake slices
  • Thinly sliced beef
  • Egg
  • Anything else you’d like to experiment with!

What are your favourite topping combinations?

Variations & Substitutes

  • For a vegetarian/vegan version of this dish, be sure to use kombu dashi powder – it’s made with only seaweed and no bonito flakes.
  • For a more intense flavour we usually use hon dashi (note, this is made with bonito flakes).

Where We Learned This Recipe

Our favourite place for Udon noodles is a tiny place near Osaka Station which we walk past on our way back to our apartment. The noodles there always have the best texture, and their dashi broth is so flavourful!

Now that we’ve been able to replicate the flavours so easily at home, we’re in heaven, and love that we can bring another little piece of Japan back home with us.

    I decided to have udon last night and came across this recipe, along with the recipe for okonomiyaki and daifuku mochi, so last night was a Japanese feast that brought me right back to my last holiday! Warm and comforting udon with the crispy and saucy okonomiyaki finished off with a soft mochi (I filled mine with whipped cream, my fave) so good! And looking at your about us section you’re from little old Adelaide too! Howdy neighbours and keep being awesome👋

      Well hello there neighbour Jess from Adelaide! *high five!* 😀 Haha – Wow, sounds like you went on quite the Japanese adventure. So glad you could recreate the flavours and pretend to be back in Japan for a night. Sounds epic with cream in the mochi too – how decadent! Did you semi-freeze the cream to wrap the mochi over it? Or just be uber careful sealing it up?

    It was perfect! I’ve been cooking this for 3 Fridays now (no-meat day of the week for us, Catholic, by choice). So happy with it. Wish I could attach my photo, but don’t know how.
