Udon Soup – A classic Japanese meal made with thick udon noodles in a flavorful broth. This is a delicious dish that can be made in less than 20 minutes!
Udon soup is my favorite food. I first fell in love with it in (of all places) Disney World. Yes, Japan in Epcot had some wicked udon that has stuck with me all of these years. Ever since then, it has become one of my go-to recipes to get at any Japanese restaurant or in Japan.
Now don’t worry, this is such an easy recipe that really anyone can make. Start to finish, you need about 20 minutes and just a few simple ingredients. It’s as simple as boiling the noodles, combining a few ingredients in a pot and warming them up into a broth, and then combining the noodles and broth. Easy peasy!
There are many varieties of udon soups with some of the other being meat-centric such as chicken udon or beef udon along with other types such as kitsune, tempura, curry, miso, nabeyaki, etc. All of them are amazing but this is the most basic of the recipes with a traditional noodle broth.

If you are using dashi powder, then you will need to bring the amount of water needed for the recipe to a boil and then add in 1 teaspoon of dashi powder per cup of water. (example: 4 teaspoons of dashi powder for 4 cups of water)
Tips and tricks on this udon soup recipe
- If you can’t find any of the ingredients at your local grocery store, then either an Asian market or Amazon will have all of them for just a few dollars.
- Light soy sauce is different from dark soy sauce and effects the taste of the broth. You can use just one type of soy sauce but the broth will not taste the same.
- You can make homemade udon noodles to go in the soup like I did.
- To store, keep the noodles and broth in separate containers. The soup will be good for about 2-3 days.

This broth was delicious! My husband and I loved it so much. I had to do some substitutions: broth for the dashi because we're vegan, sugar and rice vinegar for the mirin, and Bragg's for the light soy sauce. Didn't matter...still tasted like our beloved Udon restaurant that closed during the pandemic. Came together in no time at all and was so rich and complex. Next time, I'll have the correct ingredients on-hand. Thank you so much for sharing.

This was delicious and easy. Instead of dried noodles, I used frozen udon noodles from an Asian market. It was more delicious and nearly as easy as the soups packaged in plastic bowls. My goal is to reduce plastic and this recipe happily fulfills that goal. Thank you!
