Remove the guts from the dried anchovies and microwave them for 30 seconds.

Slice the radish and potatoes into flat pieces.

Cut the beef into bite-sized pieces and place in a pot along with the radish and potatoes.

Add 1 tbsp minced garlic, 1 tbsp soy sauce (for beef), 2 tbsp fish sauce (for radish and potatoes), and 1 tbsp sesame oil. Mix well while pressing the beef with a spoon to evenly coat with seasoning.

Add 900ml water and the prepared anchovies to the pot. Boil on high heat until the soup starts to smell aromatic.

After boiling for 8 minutes, add the sliced onion and green onion. Boil for another 2 minutes.
