Toshikoshi soba ingredients list.
  • Soba noodles – Soba noodles are popular Japanese long noodles made by kneading buckwheat flour with water, stretching it out thinly, and cutting it into thin strips. Dried, fresh, or frozen soba noodles are available at grocery stores. I use fresh soba noodles in this recipe.
  • Egg (make onsen tamago), kamaboko fish cakes, tenkasu (crispy tempura flakes), wakame seaweed, and scallions (green onions) for the toppings. To explore the variations, check out the topping section and find more options!
  • Dashi, salt, mirin, and soy sauce for dashi-based broth. Dashi stock is the key ingredient bringing rich umami to Japanese cooking (find more in What is dashi). It’s typically made from bonito flakes, but I use store-bought kombu dashi powder in this recipe. If you like to make homemade noodle soup from scratch, try this Mentsuyu recipe!

Helpful tips

  • Adjusting Soup Seasoning: If your noodle soup is too salty, you can balance it by diluting it with water. Conversely, if it’s too mild, add more mentsuyu to enhance the flavor.
  • Soba noodles typically take a couple of minutes to cook frozen noodles and around 10 minutes or more for dried or fresh noodles. The cooking time can vary depending on the type and brand of soba noodles, so please follow the package directions.
