What is Kong Guksu?

Kong guksu is a Korean dish made with noodles and a chilled soymilk broth. It’s nutty, rich and creamy, no dairy required! This recipe is naturally vegan. To make a gluten-free version, simply substitute with gluten free noodles.

The flavour of this soup is a little more mild. It really allows the richness of the nuts and beans to shine.

How to Serve Korean Soybean Soup

This noodle soup is served cold. In fact, there are often ice cubes in the bowl to keep it super chilled. It’s great to enjoy during the summer and warmer seasons especially.

And because the soup has a more mild flavor, it’s often enjoyed with accompanying “ban chan” or side dishes like kimchi and fresh cucumbers.

Ingredients for Vegan Soybean Soup

Here’s what you need for this vegan and gluten-free soup:

  • Soy beans. These add richness and body, plus protein, to the soup.
  • Pine nuts. For creaminess.
  • Sesame seeds. These add a major nutty flavor to enrich your broth.
  • Cucumber. This is a refreshing topping to cut through the richness of the soup.
  • Gluten-free noodles. Use any kind you like!

Ingredient Notes

I like to use a combination of soybeans, pine nuts and sesame seeds for extra flavour. However, you can also use only soybeans or only pine nuts. Other nuts and seeds to consider using include pumpkin seeds, peanuts, cashews etc.

If you’d like to make this recipe soy-free, you can omit the soybeans. However, I recommend adding another nut or seed in place, like sunflower seeds or cashews. Pine nuts can have a strong flavor on their own, and they are quite pricey, which is why I like to use a combination.

If you’re allergic to nuts, consider replacing pine nuts with seeds like sunflower or use a heavier hand with the sesame seeds.

How to Make Soybean Soup

Making this recipe is fairly simple. Simply soak the soybeans overnight, then boil them until tender. Next, blend the cooked soybeans with pine nuts and sesame seeds to make a milky broth. After straining, you’re ready to pour over noodles and serve.

Make-Ahead Korean Chilled Soup

You can prep the milk broth in advance. However, fresh plant milks tend to spoil after a few days. So don’t keep it in the fridge for more than 2-3 days maximum.
