Kake Udon is one of Japan's simplest and most comforting noodle dishes, featuring thick, chewy udon noodles served in a light, savory dashi broth. Its beauty lies in its simplicity, allowing the delicate flavors of kombu, bonito, soy sauce, and mirin to shine. Popular throughout Japan as an everyday meal, Kake Udon is enjoyed year-round and serves as the foundation for many other udon variations.

What is Kake Udon?

Kake Udon (かけうどん) is a traditional Japanese noodle soup consisting of freshly cooked udon noodles served in a hot broth known as Kakejiru. The broth is typically made from dashi, Japanese soy sauce, mirin, and salt, creating a clear, mildly seasoned soup that complements the soft yet chewy noodles.

Unlike heavily topped noodle dishes, Kake Udon focuses on balance and simplicity, often garnished with only sliced green onions and a sprinkle of shichimi togarashi (Japanese seven-spice blend).

Choosing the Right Udon Noodles

The best udon should be:

  • Thick
  • Soft
  • Chewy
  • Smooth
  • Fresh or frozen for the best texture

Frozen udon often provides a texture very close to freshly made noodles and is widely used in Japanese households.

Making the Dashi Broth

Step 1: Heat the Dashi

Pour the dashi into a saucepan.

Bring to a gentle simmer.

Do not boil vigorously.

Step 2: Season the Broth

Add:

  • Soy sauce
  • Mirin
  • Salt
  • Sugar (if using)

Simmer gently for 3–5 minutes.

Taste and adjust the seasoning if needed.

The broth should be light, balanced, and savory without being overly salty.

Cooking the Udon

Bring a large pot of water to a rolling boil.

Cook the udon according to the package instructions:

  • Fresh udon: 2–3 minutes
  • Frozen udon: 1–2 minutes
  • Dried udon: 8–10 minutes

Drain thoroughly.

Briefly rinse under warm water to remove excess starch while keeping the noodles warm.

Assembling the Kake Udon

Divide the cooked noodles evenly among four warmed serving bowls.

Pour the hot dashi broth over the noodles until fully covered.

Top with:

  • Sliced green onions
  • Kamaboko (optional)
  • A light sprinkle of shichimi togarashi
  • Grated ginger (optional)
  • Toasted sesame seeds (optional)

Serve immediately while hot.

Understanding Dashi

Dashi is the heart of Kake Udon.

Traditional dashi is made from:

  • Kombu (dried kelp)
  • Katsuobushi (bonito flakes)

Alternative versions include:

  • Shiitake mushroom dashi
  • Kombu-only vegetarian dashi
  • Mixed seafood dashi

A well-made dashi creates a clean, deeply savory broth with natural umami.

Chef's Tips

  • Use high-quality dashi for the best flavor.
  • Avoid over-seasoning the broth.
  • Warm the serving bowls before assembling.
  • Cook noodles just before serving.
  • Do not overcook the udon.
  • Taste the broth before serving.
  • Serve immediately for the best texture.

Egg Udon
