Easy Korean Oyster Broth Recipe (Gulguk)

Korean oyster broth

Korean oyster broth, or Gulguk, is a popular oyster soup in Korean cuisine. The liquid is almost clear and very briny. It is a lovely light broth, basically the opposite end of the scale to French onion soup.

Gulguk is also a very easy broth to make. A few ingredients tossed into some cups of water and brought to a boil is about the extent of it.

Unlike most soup recipes that use a flavorful stock as the base, this oyster soup only requires water. The oysters, kelp, and radish provide all the salty, umami taste needed to make a delicious soup.

Fast facts

It’s nutritious

Oysters are known as “milk of the sea” thanks to their high nutritional content. They are high in iron, protein, zinc, calcium, and omega-3 fatty acids.

Any oysters will work

Frozen, canned, or jarred oysters are suitable for use in soup and are usually much cheaper than the fresh alternative.

Got no Korean radish?

Korean radish, or mu, can often be found at Asian grocers. If you can’t get any where you live, another suitable option is daikon radish; this vegetable is more readily available.
