Ingredients

Scale

Broth 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

Noodles and Garnishes

  • 1 pound dried udon noodles
  • 1/4 cup green onions, thinly sliced
  • Seven-spice mixture (optional)

Instructions

  1. Cook Noodles: Prepare the udon noodles as per the package instructions. Once cooked, drain the noodles and rinse them under cold water to remove excess starch and prevent sticking. Set the noodles aside.
  2. Prepare Broth: 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 well and reduce heat to a simmer. Continue to cook until the sugar and dashi granules are fully dissolved, creating a fragrant and savory broth.
  3. Assemble and Serve: Divide the cooked udon noodles evenly into four serving bowls. Pour the hot broth over the noodles. Garnish each bowl with thinly sliced green onions and, if desired, a sprinkle of seven-spice mixture for added flavor and spice. Serve immediately to enjoy the soup at its best.

Notes

  • Rinsing the noodles under cold water after cooking prevents them from becoming overly soft and sticky.
  • Adjust the soy sauce to your preferred saltiness and taste.
  • Seven-spice mixture is optional but adds a pleasant spicy kick; it typically includes chili pepper, sesame seeds, and other spices.
  • For a richer broth, you can add kombu (kelp) or dried shiitake mushrooms while simmering.
  • This soup is best enjoyed fresh but can be stored separately in the refrigerator for up to two days.
