Lao khao soi — clear pork-tomato broth over flat rice noodles, topped with a fermented-soybean-and-pork sauce. Not the Chiang Mai curry version.
Luang Namtha and Phongsali in the northern Lao uplands, brought by Tai Lue and Yunnanese Hui traders along the Burma-Yunnan caravan route before the 1900s. The fermented-soybean topping (tao jeow) is the Yunnanese fingerprint; the Chiang Mai curry khao soi is a separate Burmese-Muslim adaptation.
Ban Vieng Neua in Luang Prabang's old quarter is the reference stall — pork bone simmered from 4am, tao jeow ground fresh daily. Don't confuse with Thai khao soi (curry, egg noodles); the Lao name and the dish migrated together but the bowl is unrelated.
Thin flat rice noodles in a pale red-orange broth flecked with tomato seeds. Spoon of dark fermented-pork sauce on top melts in as you stir. Pork-savory broth, tomato tang, fermented-bean funk, fresh lime and bean-sprout crunch from the side plate.
Two stocks in one bowl: a clear pork-bone broth (60-min simmer) and a separately-cooked tao jeow ground-pork sauce. They sit unmixed until the eater stirs — diluting the sauce slowly across the bowl, so the last spoonful is funkier than the first.
Variations
Luang Prabang style (lighter, more tomato); Phongsali style (Yunnanese, heavier tao jeow, douchi included); Vientiane style (clearer broth, less fermented topping). Pak Beng riverside stalls add river fish broth to the pork.

How it's made
5 steps · 19 min active + 1 hour 10 min waiting
- 18 min
Brown 500 g pork ribs in oil 8 min.
Watch outBrown the ribs hard until deeply colored on all sides — that seared crust is what gives the finished broth its depth, so don't rush it pale.
- 25 min
Add 1 chopped tomato + 1 onion + garlic; sauté 5 min.
- 360 min
Pour in 1.5 L water + fish sauce; simmer 1 hr to clear broth.
Watch outKeep the broth at a gentle simmer, not a rolling boil, and skim the scum — hard boiling clouds it, and this bowl wants a clear pork stock.
- 410 min
Make fermented soybean-pork topping: pork mince + tau jiao paste; cook 10 min.
Watch outCook the tao jeow pork topping down until it's thick and the fat separates out — it sits on top unmixed, so it needs to be concentrated and salty enough to season each stir.
- 56 min
Boil flat rice noodles 3 min; drain; ladle broth over with topping.
