Tteokguk is a traditional Korean soup made with sliced rice cakes, typically enjoyed during the Korean New Year celebration.

This dish holds cultural significance as it symbolizes the gaining of a year in age and is believed to bring good luck for the coming year.

To prepare Tteokguk, start by slicing the rice cakes and chopping green onions. Simmer beef with garlic and soy sauce to create a savory broth. Add the rice cakes to the broth and cook until they become tender.

Once the rice cakes are cooked, garnish the soup with sliced egg and green onions before serving it hot.

While Tteokguk is traditionally made with beef, you can customize it by using different proteins such as chicken or seafood, or by adding vegetables like mushrooms and spinach.

In Korea, Tteokguk is often served as a main dish during family gatherings and festive occasions, accompanied by various side dishes like kimchi and pickled vegetables.

It's important to note that Tteokguk can be high in sodium due to the soy sauce, so those watching their salt intake should consume it in moderation. The dish is also a good source of protein and can provide essential nutrients from the added vegetables.
