Japanese Udon Noodle Soup

This delicious and impressive udon noodle soup is the easiest soup you may ever make. It is also one of the tastiest. Filled with tender bok choy, sugar snap peas, and pillowy poached eggs, the broth is simple, light, and so flavorful, with hints of star anise and cinnamon. The star of the soup, however, is the thick, chewy noodles (perfect for slurping).

What are Udon Noodles?

Udon, popular in Japanese cuisine, is a thick noodle made from wheat flour. Udon noodles may be served hot or cold, in soups, salads, or stir-frys. The simplest way to serve this Japanese noodle is as a hot soup, kake udon, with a mild broth called kakejiru made from soy sauce, mirin, and dashi.

Udon noodles are not gluten-free.

This recipe is not (at least to my knowledge) an accurate representation of “traditional” udon noodle soup. This is my own delicious made-up Asian-inspired soup anyone can make using simple ingredients.

How to Make Udon Noodle Soup

1. Simmer the star anise and cinnamon stick in the vegetable broth for about 10 minutes allowing the flavor from the spices to infuse with the broth. Uncover and remove the spices using a slotted spoon.

2. Meanwhile, bring a second pot of water to a boil. Once boiling, cook your udon noodles according to package instructions – do not overcook. Drain and rinse with cold water.

3. Stir the sugar, soy sauce, and fresh lime juice into the broth.

4. Add the green onions, sugar snap peas, and bok choy to the soup. Cook until the vegetables are tender, approximately 3-5 minutes. Remove from heat and season with additional soy sauce or salt, to taste.

5. Divide the cooked noodles and soup between two bowls. Garnish with fresh cilantro, scallions, and red pepper flakes, if desired.

Alternatives to Udon Noodles

Easily make this recipe with ramen noodles, soba noodles, or even spaghetti noodles in place of udon. Remember to cook the noodles according to the package instructions.

Ingredients
 
 

  • 5 cups vegetable broth - or low-sodium chicken broth
  • 2 whole star anise

  • 2 teaspoon sugar
  • 2 tablespoon soy sauce
  • 2 tablespoon fresh lime juice
  • 2 servings udon noodles - 6.3 oz/180 g dry udon noodles; 1.1 lb/500 g frozen or parboiled udon noodles

  • 10 oz. fresh sugar snap peas

Instructions
 

  • In a medium saucepan, bring the vegetable (or chicken) broth to a low boil. Reduce heat to medium-low and add the star anise and cinnamon stick. Cover, and allow the broth and spices to simmer for approximately 10 minutes to infuse the flavors of the spices into the broth. Uncover and carefully remove the spices with a slotted spoon.
  • Bring a separate pot of water to a boil. Cook the udon noodles according to the package directions. Once cooked, drain and rinse with cool water. This will help to remove some of the excess starch.
  • Add the sugar, soy sauce, and fresh lime juice to the broth.
  • Add the green onions, sugar snap peas, and bok choy to the soup. Mix well to combine. Return the soup to a simmer and continue to cook until the vegetables have softened (about 3-5 minutes).
  • Remove from heat and season to taste. Add additional soy sauce or salt, if needed. Divide the udon noodles and soup between two bowls and garnish with fresh cilantro and red pepper flakes. Top with a poached egg or boiled egg, if desired.

Jessica’s Notes

  • This soup is best enjoyed immediately as the noodles will dissolve within the broth over time. Freezing is not recommended.

    I made this soup last night. It was very tasty. I added some raw bean sprouts and some sliced Rotisserie white chicken breast in the bowl before I added the broth. I enjoyed the flavor quite a bit. It’s a very easy and quick soup to make. The hardest part of the process was finding Udon Noodles in our area. I plan to make this again soon. Thanks for sharing your recipe.

      Hi Carrie,

      Yes, mostly from the regular chicken stock and soy sauce. If you are looking for less salt, simply substitute with low sodium chicken/vegetable broth and low sodium soy sauce, and that will dramatically reduce the sodium content 🙂
