Easy Prawn Tempura Udon Soup

Japanese

When I need something quick, cosy and ridiculously easy, this Prawn Tempura Udon Soup is one of the dishes I turn to. Also known as Kake Udon, this Japanese noodle soup is all about the broth. The broth is subtle, savoury and packed with umami from the dashi. It's basically comfort in a bowl with springy udon noodles, crispy prawn tempura and chewy slices of narutomaki. The best part? It comes together in around 15 minutes!

Possible Substitutions

  • Prawn tempura: Use vegetable tempura, chicken katsu or tofu if you want to switch things up.
  • Udon: Fresh or frozen udon both work, I prefer frozen! Just follow the packet instructions as cooking times can vary.
  • Dashi: Use instant dashi powder for convenience, or make your own dashi if you have the time.
  • Narutomaki: You can leave this out or swap it for another Japanese fish cake.

Things to Keep in Mind

  • Keep the tempura separate until you're ready to eat so it stays nice and crispy.
  • Taste the broth before adding more salt as the soy sauce and dashi already add plenty of seasoning.
  • If you're using a ddukbaegi, be careful as it gets very hot and will continue cooking after you take it off the heat.

Fridge

Storage

This is best eaten fresh, especially because the tempura will lose its crispiness once it sits in the broth.

Method

Cook the prawn tempura

Cook the frozen prawn tempura according to the packet instructions, either in the air fryer or oven, until golden and crispy.

Cook the udon

Bring a pot of water to a boil and cook the udon according to the packet instructions. Once cooked, drain and set aside.

Make the broth

While the udon cooks, add the water, dashi powder, light soy sauce, mirin and salt to a separate pot or ddukbaegi (Korean earthenware pot, like I'm using in my video).

Bring to a gentle boil, then taste and adjust the seasoning to your liking.

Cook the narutomaki

Add the slices of narutomaki to the broth and simmer for around 2 minutes, just to warm them through.

Assemble & serve

Turn off the heat and add the cooked udon to a serving bowl.

If you're using a ddukbaegi like I am, you can add the udon straight into the pot.

Top with the crispy prawn tempura, narutomaki, spring onions and a sprinkle of shichimi togarashi, your soy-marinated egg and enjoy!
