Kimchi natto somen noodles ingredients.
  • Somen noodles: Somen are thin, white Japanese noodles made from wheat flour. They cook in just 1–2 minutes, making them perfect for quick and light summer meals.
  • Toppings: This recipe uses cucumber, kimchi, and natto. Cucumber adds a fresh crunch, but you can also use other crunchy vegetables such as lettuce or carrots. If you’re not a fan of natto, tofu is a great substitute.
  • Seasonings: The sauce is made with soy sauce, kombu dashi powder, rice vinegar, and sesame oil. Since kimchi and natto can vary in flavor and saltiness, feel free to adjust the seasoning to your taste.

Equipment

  • Medium saucepan
  • Strainer

Ingredients
  

  • 2 bundles somen noodles
  • 1 cucumber, shredded
  • ½ cup kimchi
  • 2 packs natto
  • toasted sesame seeds, optional
Sauce
  • ¾ cup water
  • 1 Tbsp soy sauce
  • A pinch of kombu dashi powder
  • A splash of vinegar
  • 2 tsp sesame oil

Instructions
 

  1. Cook Somen Noodles: Boil the somen noodles according to the package instructions, about 1–2 minutes. Drain the noodles in a strainer, then rinse under cold running water to cool them down and remove excess starch. Drain well.
  2. Prepare the Sauce: In a small bowl, mix water, soy sauce, kombu dashi powder, vinegar, and sesame oil.
  3. Prepare the Toppings: Shred the cucumber. Mix the natto with the sauce packet that comes with it, or use a little soy sauce instead.
  4. Serve: Place the chilled somen noodles in serving bowls. Top with cucumber, kimchi, and natto. Pour the sauce over the noodles. Finish with toasted sesame seeds and enjoy!

Notes

  • Boil with plenty of water to keep noodles from sticking.
  • Rinse under cold water right after boiling to stop cooking and remove starch; this makes them firm and chewy.
  • Adjust the seasoning to your taste. If you want more flavor, add a little extra soy sauce.
