Bún Thang (Hanoi Chicken Noodle Soup)
Why this recipe works
- Clean, layered broth: Chicken, ginger, garlic, fish sauce and salt build a savoury base without weighing down the soup.
- Delicate toppings: Fine strands of chicken, soft vermicelli and omelette ribbons give the bowl a light, carefully balanced texture.
- Bright finishing touches: Lime and sliced chilli are added at the table, so each bowl can be sharpened or warmed to taste.

Timing notes
- Serve as soon as assembled: Add the hot broth just before serving so the noodles stay springy and the herbs remain fresh.
- Cool the omelette before slicing: Letting the thin omelette rest briefly makes it easier to roll and cut into neat ribbons.
Texture tips
- Keep the broth clear: Skim early and maintain a very gentle simmer; vigorous boiling can cloud the broth and toughen the chicken.
- Protect the noodles: Cook the vermicelli separately and drain well before dividing between bowls.
Authenticity notes
- Hanoi-style restraint: Bún thang is recognised for its clear broth, fine-cut toppings and balanced seasoning rather than heavy spicing.
- Table-side brightness: Lime and chilli are typical finishing elements, adding acidity and heat without overpowering the delicate broth.
Make-ahead tips
- Store components separately: Keep the broth and chicken apart from the noodles, herbs and omelette for the best texture.
- Reheat the broth properly: Bring the broth back to a full simmer, then warm the chicken in it before ladling over freshly cooked or refreshed noodles.
- Freeze the broth and chicken: The broth and shredded chicken freeze well; leave noodles, herbs, lime and chilli for serving day.

Ingredients
Instructions
- Put the chicken thighs in a stockpot and cover with about 2 litres of cold water. Bring to a gentle simmer, skimming any foam for the first 10 minutes so the broth stays clear. Add the ginger (sliced) and 2 peeled garlic cloves, then simmer very gently for 35 to 45 minutes until the chicken is cooked through and tender.
- Lift out the chicken and leave until cool enough to handle. Strain the broth through a sieve into a clean pot, then season with the fine sea salt and fish sauce, adjusting to taste. Keep the broth at a bare simmer while you prepare the toppings.
- Shred the chicken into fine strands, discarding skin and bones. Thinly slice the spring onion and roughly chop the fresh coriander. Finely slice the red chilli and cut the limes into wedges.
- Beat the eggs with a pinch of the fine sea salt. Heat a nonstick frying pan over medium heat and pour in a thin layer of egg, swirling to coat the base. Cook for 45 to 60 seconds until just set, flip briefly, then repeat to make thin omelettes; roll and slice into fine ribbons.
- Cook the rice vermicelli in boiling water until tender, following the packet timing. Drain well and rinse briefly with warm water to stop it sticking. Divide the noodles between bowls.
- Top each bowl with shredded chicken and the omelette ribbons, then scatter over spring onion and fresh coriander. Ladle over the hot broth until the noodles are submerged and the toppings are warmed through. Serve immediately with lime wedges and sliced red chilli for squeezing and sprinkling at the table.
Recipe notes
Tips
- Keep the broth at the gentlest simmer and skim early; a rolling boil will make it cloudy.
- For the neatest omelette ribbons, let the omelette cool for 2 minutes before rolling and slicing.
- If serving to pregnant people, young children, or anyone vulnerable, ensure the chicken is cooked through and the broth is piping hot when served.
Substitutions
- Replace Chicken thighs with Whole chicken for a slightly richer broth and a mix of light and dark meat.
- Replace Fresh coriander with Fresh mint for a different, but still classic, herbal finish.
- Replace Red chili pepper with Green chili pepper for a sharper heat.
Storage
- Refrigerate up to 3 days
- Store the broth and chicken separately from the noodles and herbs for the best texture. Chill promptly, then reheat the broth to a full simmer and warm the chicken in the hot broth before serving; cook fresh vermicelli if possible. Freeze broth and chicken for up to 2 months; defrost overnight in the fridge.
