We can’t wait for you to try this Japanese-inspired Curry Udon recipe! It’s the perfect soup to make for dinner tonight, all you have to do is grab a couple of packets of udon noodles and a block of tofu on the way home.

The simple sauce really packs a punch by itself (this is a curry udon recipe made without curry roux, so you don’t need to worry about that!), but this dish is taken to the next level with plenty of contrasting colours, flavours and textures when you get to the toppings of crispy tofu, sliced chillies, fresh coriander and DIY fried shallots.

And you don’t have to stop there — we’ve added plenty more topping ideas below!

Ingredients to make a udon soup on a wooden tray.

Ingredients

  • cooked udon noodles (we like the ready-to-wok variety that come in vacuum packed pouches – they’re easy to find in most big supermarkets)
  • cubed tofu (we like firm tofu as we can crisp it up nicely, but you can also add diced silken tofu – the Clearspring one has a really lovely texture – to the udon soup just before serving)
  • shallots (buy banana shallots if you find the round ones tricky to slice!)
  • sea salt
  • sunflower oil (or any other neutral tasting oil with a high smoke point)
  • carrot
  • fresh red chilli (we used a bird’s eye chilli here for heat, but you can go for a milder variety if you prefer)
  • fresh coriander
  • onion
  • garlic
  • fresh ginger
  • coconut milk
  • vegetable stock
  • medium curry powder (a Japanese-style powder will work best here)
  • soy sauce
  • honey (or maple syrup if you’re looking to make this Kare Udon recipe vegan!)
  • mirin (mirin is a Japanese rice wine used in cooking that is similar to sake, but it is a bit sweeter and has a less alcohol. Most supermarkets have it but you can always substitute dry sherry or sake with a pinch of sugar instead)
  • fresh lime juice

  • silken tofu
  • stir fried shiitake mushrooms
  • lime wedges

Frequently Asked Questions

What are Udon Noodles?

Udon noodles are thick, Japanese wheat flour noodles with a really satisfyingly chewy finish. If you can’t find any pretty much any noodle that has a bit of bite would work in this soup, from medium egg noodles to thick cut rice noodles. Homemade scissor-cut noodles would also be a good choice as we think it is the chewiness of the udon noodles that make this soup special!

Are these curried noodles vegan?

The recipe as written contains honey which is not suitable for vegans, but an easy switch is maple syrup – otherwise, you’re all set!

I’ve not used all the crispy shallots, where else can I use them?

I LOVE to sprinkle crispy shallots on any kind of noodle bowl, over rice and even over pasta or salads that need a bit of crunch. Keep them in an air tight jar and remember to finish them off within three days for optimum crunchiness!
