Kuay Jab
ก๋วยจั๊บ
Kuay Jab is a Thai-Chinese noodle soup made with rolled rice noodle sheets in a dark, five-spice pork broth — topped with braised pork belly, offal, and boiled egg.
Cultural Origin
Kuay jab is a Chinese-Thai noodle soup served in two distinct styles: the Bangkok-Teochew kuay jab nam sai uses rolled rice-sheet noodles in a peppery clear pork broth with crispy pork belly and offal, while kuay jab yuan is a Vietnamese-derived version with tapioca noodles and a thicker, sweeter broth. Both styles are urban shophouse dishes rather than regional specialties, with kuay jab nam sai strongly associated with Bangkok's Chinatown (Yaowarat).
Regional Variants

A peppery, savoury broth rather than a sweet or sour one — coarsely ground white pepper is added heavily enough to be a defining flavour, and the rolled noodle sheets bring a silky, slippery texture unlike any other noodle in this list.
How Kuay Jab Is Made
- 1
Broth
A pork bone broth is simmered with five-spice and finished with a generous amount of white pepper, which is what gives the dish its peppery signature rather than chilli heat.
- 2
Noodle sheets
Flat rice-paper sheets are rolled loosely into tubes rather than cut into ribbons, so they unfurl slightly once dropped into the hot broth.
- 3
Pork belly
Pork belly is braised separately until tender, then sliced and added to the bowl rather than simmered directly in the serving broth.
- 4
Offal
Cooked pork offal is added alongside the belly for diners who want it, since some versions are ordered with offal and some without.
- 5
Finishing
Crispy fried garlic and a boiled egg are added last so their texture and richness stay distinct from the peppery broth underneath.
When It’s Eaten
A breakfast dish above all else, especially in Bangkok's Chinatown where shops open before dawn and are busiest between roughly seven and eleven in the morning, rather than a lunch or dinner order.

What people get wrong
Mistaking the rolled noodle sheets for a type of dumpling or wonton because of their shape — they are plain rice-flour noodle sheets rolled into tubes, not filled, and the texture is meant to be silky and slightly slippery rather than chewy.
Where to Try It
Bangkok Chinatown (Yaowarat) and Thai-Chinese noodle shops open in the early morning.
Tips
- This is a serious breakfast dish — Yaowarat Chinatown shops are packed from 7–11 AM with locals eating Kuay Jab before work.
