What is Bibim Guksu (비빔국수)?

In Korean, Bibim Guksu" (비빔국수) translates to "mixed noodles" in English. The term "bibim" means "mixed," and "guksu" refers to "noodles".

It is a popular Korean noodle dish made with thin noodles, fresh vegetables, and a spicy-sweet gochujang-based sauce. It is said that it is eaten cold to combat the summer heat.

Why it works?

It's packed with flavour - Gochujang is one of those super-charged ingredients that does ALL the heavy lifting for flavour. Stir it into anything and you have a ready made wallop of taste. Any eating it cold with noodles is a revelation.

It's quick - The only cooking you need to do is some noodles and egg -simple! The rest is assembly which, let's face it, is the best way to cook!

Stuff You'll Need

There's not a lot to hunt around for with my Bibim Guksu recipe here are the key flavours.

  • Noodles - I love the light, nutty chewiness of Soba Noodles, but you can use a regular Asian wheat noodle or indeed rice noodles if you're so inclined.
  • Gochujang Paste - This Korean chilli paste is becoming easier to find in most supermarkets these days. If not, almost all Asian markets stock it. Failing that, the Internet has everything!
  • Kimchi - For a little more umami and funky, crunchy spice, grab a little kimchi - whichever kind you prefer. I opt for regular cabbage kimchi and buy the spiciest I can find.
  • Flavourings - Soy sauce, rice vinegar, sugar and sesame oil add to the complexity of the sauce.
  • Cucumber - The cold, cooling nature is the perfect counter balance to the spicy sauce.
  • Egg - no Asian noodle bowl seems complete without a 'just set' jammy boiled egg.
  • Garnishes - I opt for extra chilli flakes and a few mixed black & white sesame seeds to finish the dish off.

Step by Step

Making Bibim Guksu at home is simple. There are only a few basic cooking steps and the rest is assembly. My kind of cooking. Cook your noodles to the packet instruction and then plunge into cold water. Drain and set aside. Then boil your egg, cool and peel and set aside.

  1. Step 1 - Finely chop the kimchi and place in a bowl with the gochujang, sesame oil, vinegar, sugar and soy sauce.
  2. Step 2 - Stir this well until completely combined
  3. Step 3 - Mix the cold noodles with the sauce

Now all you need to do is arrange some noodles in a deep Asian bowl and then arrange a good handful of cucumber batons followed by your egg, cut in half. Sprinkle over your garnishes and you're done!
