Ingredients

  • 5 cups water
  • 5 teaspoons instant dashi granules
  • 2 tablespoons dark soy sauce
  • 2 tablespoons light soy sauce
  • 1 tablespoon sugar
  • 2 tablespoons mirin
  • 1 pound dried udon noodles
  • 1/4 cup green onions, thinly sliced
  • Seven-spice mixture (optional)

Instructions

  1. Step 1: Cook udon noodles according to the instructions on the packaging. Once done, drain and rinse them under cold water to stop the cooking process. Set aside.
  2. Step 2: In a large pot, bring 5 cups of water to a boil. Add the instant dashi granules, dark soy sauce, light soy sauce, sugar, and mirin. Stir and simmer until the sugar and dashi have completely dissolved.
  3. Step 3: Divide the cooked noodles evenly among four bowls. Pour the hot broth over the noodles, then garnish with thinly sliced green onions. Sprinkle seven-spice mixture on top if you like a little extra heat. Serve immediately.

Tips & Variations

  • For extra protein, add cooked chicken, tofu, or a soft-boiled egg to the soup before serving.
  • If you prefer a richer broth, substitute part of the water with dashi stock made from kombu and bonito flakes.
  • Adjust soy sauce quantities to taste for a saltier or milder broth.

Storage

Store leftover broth separately in an airtight container in the refrigerator for up to 3 days. Keep cooked noodles refrigerated but consume within 1 day for best texture. Reheat the broth gently on the stove and warm the noodles briefly before serving.

  • 2 tablespoons dark soy sauce
  • 2 tablespoons light soy sauce
  • 1 tablespoon sugar
  • 2 tablespoons mirin

Noodles and Garnish

  • Seven-spice mixture (optional)

Instructions

  1. Cook the udon noodles: Prepare the dried udon noodles according to the package instructions, usually boiling them until tender. Once cooked, drain the noodles and rinse under cold water to stop the cooking process and prevent sticking. Set aside.
  2. Prepare the broth: In a large pot, bring 5 cups of water to a boil. Stir in the instant dashi granules, dark soy sauce, light soy sauce, sugar, and mirin. Reduce the heat to a simmer and cook until the sugar and dashi granules have fully dissolved, creating a balanced, flavorful broth.

Notes

  • Instant dashi granules provide a quick and easy way to make authentic Japanese broth, but homemade dashi can also be used for deeper flavor.
  • Adjust the amount of soy sauce and sugar to taste depending on your preference for saltiness and sweetness.
  • Seven-spice mixture (shichimi togarashi) adds a spicy, aromatic kick but is optional.
  • Rinsing noodles after cooking prevents them from becoming mushy and helps maintain a pleasant texture in the hot broth.
  • For a heartier meal, consider adding protein like tofu, chicken, or tempura vegetables.
