Description

A comforting and traditional Japanese Udon Soup featuring a flavorful kombu dashi broth seasoned with soy sauce, mirin, and sugar, served over chewy udon noodles and garnished with fresh green onions and nori strips. Perfect for a quick, warm meal that showcases authentic Japanese flavors.


Ingredients

Scale

Broth Ingredients

  • 4 cups water
  • 1 piece dashi kombu (dried kelp), about 4 inches
  • 2 tbsp soy sauce
  • 1 tbsp mirin
  • 1 tsp sugar

Noodles and Garnish

  • 200 g udon noodles (fresh or dried)
  • 2 green onions, thinly sliced
  • 1 sheet nori, cut into strips


Instructions

  1. Soak Kombu: In a medium pot, soak the dashi kombu in 4 cups of water for 10 minutes to extract initial flavors and soften the kelp.
  2. Heat Broth: Place the pot over medium heat and warm the water until it is nearly boiling. Just before boiling, remove the kombu carefully to avoid bitterness.
  3. Season Broth: Add 2 tablespoons soy sauce, 1 tablespoon mirin, and 1 teaspoon sugar to the pot. Stir gently and let the broth simmer for 5 minutes to blend the flavors.
  4. Cook Udon Noodles: Prepare the udon noodles according to the package instructions, usually boiling them until tender. Once done, drain and rinse under cold water to stop cooking and remove excess starch.
  5. Assemble Soup: Divide the cooked udon noodles evenly between two serving bowls. Pour the hot kombu broth over the noodles to warm them through.
  6. Garnish and Serve: Top each bowl of soup with the sliced green onions and nori strips. Serve immediately while hot for the best flavor and texture.

Notes

  • Using fresh udon noodles will give a more authentic texture compared to dried.
  • Do not let the broth boil vigorously after adding kombu to prevent bitterness.
  • You can add other toppings like sliced fish cake, mushrooms, or boiled eggs for variety.
  • Mirin adds a gentle sweetness and shine to the broth; substitute with a mix of sugar and sake if unavailable.
  • For a vegetarian version, ensure your dashi kombu is not mixed with fish-based stock ingredients.
