For the Soba Noodles

  • 200 grams of soba noodles (buckwheat noodles)

For the Dipping Sauce (Tsuyu)

  • 1 cup dashi (Japanese stock)
  • 1/4 cup soy sauce
  • 1/4 cup mirin (sweet rice wine)
  • 1 tablespoon sugar


  • Nori (dried seaweed), cut into thin strips
  • Green onions, finely chopped
  • Wasabi, to taste
  • Grated ginger, to taste
  • Sesame seeds

Preparation Steps

1. Cooking the Soba Noodles

  1. Boil Water: Bring a large pot of water to a boil.
  2. Cook Noodles: Add the soba noodles to the boiling water. Cook according to the package instructions, usually around 4-6 minutes.
  3. Rinse Noodles: Once cooked, drain the noodles and rinse them thoroughly under cold running water to remove excess starch. This will prevent the noodles from sticking together and give them a firm texture.
  4. Drain Well: Allow the noodles to drain completely. Optionally, you can refrigerate them to chill further.

2. Preparing the Dipping Sauce (Tsuyu)

  1. Combine Ingredients: In a saucepan, combine dashi, soy sauce, mirin, and sugar.
  2. Heat Sauce: Bring the mixture to a gentle simmer over medium heat, stirring occasionally until the sugar dissolves.
  3. Cool Sauce: Remove from heat and let the sauce cool to room temperature. You can also chill it in the refrigerator for a colder serving.

3. Assembling and Serving

  1. Plate Noodles: Place the cooled soba noodles on a bamboo mat or a plate.
  2. Add Garnishes: Sprinkle nori strips and chopped green onions over the noodles.
  3. Serve Sauce: Pour the dipping sauce into small individual bowls.
  4. Enjoy: Serve the soba noodles with the dipping sauce on the side. Add wasabi, grated ginger, and sesame seeds to the sauce as desired for additional flavor.

Tips for the Perfect Zaru Soba

  • Quality Noodles: Use high-quality soba noodles for the best texture and flavor.
  • Cold Rinse: Rinsing the noodles under cold water is crucial to stop the cooking process and to remove excess starch.
  • Fresh Ingredients: Use fresh and high-quality ingredients for the dipping sauce and garnishes.
  • Optional Additions: You can add other garnishes like shiso leaves, daikon radish, or tempura bits for extra flavor and texture.


  • Cha Soba: Use green tea soba noodles for a different flavor and color.
  • Spicy Tsuyu: Add a touch of chili oil or shichimi togarashi (Japanese seven-spice) to the dipping sauce for a spicy kick.
  • Vegetarian: Ensure your dashi is vegetarian by using kombu (kelp) and shiitake mushrooms instead of bonito flakes.
