📝 About This Recipe

Kake Udon is the soul-soothing cornerstone of Japanese noodle culture, celebrated for its elegant simplicity and deep umami profile. This dish features thick, chewy wheat noodles swimming in a crystal-clear 'Kakejiru' broth made from high-quality dashi, soy sauce, and mirin. It is the perfect warm embrace on a cold day, offering a masterclass in balancing subtle salty, sweet, and smoky flavors.

🥗 Ingredients

The Noodles

  • 2 packs Frozen Udon Noodles (Sanuki-style preferred for best texture)

The Dashi Stock

  • 4 cups Water (Filtered water provides the cleanest taste)
  • 1 piece Kombu (Dried kelp, about 4x4 inches)
  • 2 cups Katsuobushi (Dried bonito flakes, loosely packed)

The Kakejiru Seasoning

  • 2 tablespoons Usukuchi Soy Sauce (Light-colored soy sauce to keep the broth clear)
  • 1.5 tablespoons Mirin (Authentic brewed mirin is best)
  • 1/2 teaspoon Sugar (To balance the saltiness)
  • 1/4 teaspoon Kosher Salt (Adjust to taste)

Garnish and Finish

  • 2 stalks Green Onions (Finely sliced on a bias)
  • 2 tablespoons Tenkasu (Crunchy tempura bits)
  • 4 slices Kamaboko (Japanese pink-rimmed fish cake)
  • 1 pinch Shichimi Togarashi (Japanese seven-spice powder for heat)
  • 1 teaspoon Ginger (Freshly grated)

👨‍🍳 Instructions

  1. 1

    Begin by wiping the kombu with a damp cloth (do not wash off the white powder, as that is pure umami) and place it in a medium pot with 4 cups of water. Let it soak for 30 minutes if time permits.

  2. 2

    Place the pot over medium heat. Just before the water reaches a rolling boil (look for small bubbles around the edges), remove the kombu to prevent the broth from becoming slimy or bitter.

  3. 3

    Add the katsuobushi (bonito flakes) to the pot and bring to a boil. Once boiling, immediately reduce heat to low and simmer gently for 2 to 3 minutes.

  4. 4

    Turn off the heat and let the flakes sink to the bottom of the pot, which takes about 2 minutes. This ensures a clear, sediment-free dashi.

  5. 5

    Strain the dashi through a fine-mesh sieve lined with paper towels into a clean pot. Gently press the flakes to extract every drop of liquid gold.

  6. 6

    Add the usukuchi soy sauce, mirin, sugar, and salt to the strained dashi. Bring it to a very gentle simmer over low heat to keep it hot while you prepare the noodles.

  7. 7

    In a separate large pot, bring plenty of water to a vigorous boil. There is no need to salt this water as the udon itself contains salt.

  8. 8

    Add the frozen udon noodles to the boiling water. Use chopsticks to gently untangle them as they thaw. Cook for 1-2 minutes or according to the package instructions until 'al dente'.

  9. 9

    Drain the noodles thoroughly in a colander. For the best texture, quickly rinse them under hot running water to remove excess starch, then shake well to remove all water.

  10. 10

    Warm your serving bowls by rinsing them with hot water; this prevents the soup from cooling down too quickly.

  11. 11

    Divide the hot noodles between the two warmed bowls, nestling them neatly in the center.

  12. 12

    Ladle the hot Kakejiru broth over the noodles until they are just submerged.

  13. 13

    Top each bowl with two slices of kamaboko, a generous sprinkle of green onions, and a spoonful of tenkasu.

  14. 14

    Serve immediately with a small mound of grated ginger on the side and a dusting of shichimi togarashi for those who enjoy a subtle kick.

💡 Chef's Tips

Always use frozen udon over shelf-stable vacuum-packed ones; the frozen variety has a vastly superior 'koshi' (chewy bounce). Usukuchi (light) soy sauce is essential for the aesthetic; regular soy sauce will make the broth too dark and overly earthy. Never boil the bonito flakes for too long, or the broth will become cloudy and develop a fishy 'off' flavor. If you don't have tenkasu, you can crush a few plain rice crackers or use panko breadcrumbs toasted in a little oil as a substitute for crunch. Adjust the sweetness by adding mirin half a teaspoon at a time; the broth should be savory first with a very faint sweet finish.

🍽️ Serving Suggestions

Pair with a side of vegetable or shrimp tempura for a classic 'Tempura Udon' experience. Serve with Inari Sushi (sweet fried tofu rice balls) to make a heartier meal. A chilled glass of dry Sake or a hot roasted Hojicha tea complements the umami of the dashi beautifully. Add a soft-boiled 'Ajitama' egg or a poached egg directly into the hot broth for extra richness. Include a small side dish of pickled daikon (takuan) to provide a refreshing, crunchy contrast to the soft noodles.
