This refreshing and easy Cold Zaru Soba Noodles recipe features chilled buckwheat noodles served with a savory homemade dipping sauce made from soy sauce, mirin, and dashi. Light, satisfying, and packed with umami, it's a vegan-friendly Japanese dish perfect for summer lunches or light dinners.

Ingredients

Noodles & Garnish

  • 400 g dried soba noodles
  • 4 spring onions finely shredded

Dipping Sauce

  • 50 ml soy sauce
  • 50 ml mirin
  • 600 ml dashi stock use vegan dashi if preferred

Instructions

Prepare the Dipping Sauce

  • In a bowl, mix soy sauce and mirin into the dashi stock. Transfer to the refrigerator and chill for at least 50 minutes before serving.

Cook and Rinse the Soba Noodles

  • Bring a large pot of water to a boil. Add the dried soba noodles quickly and stir to prevent sticking.
  • When the water returns to a boil, add about 1/2 cup of cold water to reduce the temperature. Repeat this step once or twice depending on the dryness of the noodles.
  • Test noodle doneness by pinching or cutting a strand—it should be just tender.
  • Drain the noodles in a colander or sieve. Rinse thoroughly under cold running water, rubbing gently to remove excess starch.
  • Drain again and set aside.

Serve

  • Arrange the cold soba noodles on serving dishes.
  • Garnish with finely shredded spring onions.
  • Serve with individual bowls of chilled dipping sauce on the side.

Notes

  • For a gluten-free version, use 100% buckwheat soba and gluten-free soy sauce.
  • To make the dish vegan, use kombu and dried shiitake to prepare vegan dashi.
  • Adding cold water while cooking helps noodles cook evenly from inside out.
  • Rinse noodles thoroughly to remove starch and prevent gumminess.
