Step 1
In a large pot, add the beef stock and water. Add star anise, cinnamon stick, bay leaves, and ginger. Bring to a boil, then reduce heat and let it simmer for about 15 minutes to infuse the flavours.

Step 2
Add soy sauce and Chinese cooking wine. Stir well. Taste and adjust seasoning if needed.

Step 3
Add the beef slices into the hot broth. Cook for 2–3 minutes until just cooked through (avoid overcooking so the beef stays tender).

Meanwhile, cook the Leimein noodles according to package instructions (usually 3–4 minutes). Drain and set aside.

Step 5
Blanch the bok choy briefly in boiling water (about 1 minute) or add directly into the broth just before serving.

Step 6
To serve, place noodles in bowls, ladle over the hot broth with beef slices, and add bok choy on top.Garnish with fresh coriander and a drizzle of chilli oil. Serve hot.
