Khao soi (khâao-sawy)
ข้าวซอย
khâao-sawy
The name, part by part — one piece does not decompose
| Part | Sound | What it means |
|---|---|---|
| ข้าว | khâao | rice |
| ซอย | sawy | the derivation is not settled — see the note |
The ข้าว is real enough. ซอย is not settled, and nothing in the name prepares you for egg noodles in a coconut curry broth with a nest of fried noodles on top.
Do not repeat a tidy story here. Sources disagree: ซอย is a real Thai verb meaning to slice finely, and a Burmese route through the northern trade roads has also been proposed, and this site's page keeps to the Burmese-Yunnanese trade history without deriving the word. Treat the derivation as contested and the name as one to learn whole. Note too that this dish's noodles are egg noodles, not rice ones, despite the ข้าว.
How Thai dish names are built, in full: Thai food, dish by dish.

Chiang Mai's curry noodle bowl: egg noodles in a coconut curry broth, chicken leg or beef, CRISPY fried noodles on top, with pickled mustard greens, shallots and lime on the side. The north's one indispensable dish.
Spice medium The chilli oil on top is optional and adjustable.
What is in it Fresh egg noodles plus fried ones, coconut curry broth (a Burmese-influenced paste), chicken drumstick or braised beef, pickled mustard greens (ผักกาดดอง), shallots, lime, chilli oil.
Vegetarian and allergies Tourist-belt Chiang Mai does tofu/veg versions widely; traditional shops do not.
Say it at every level
A1.1 Order it
ข้าวซอยไก่ครับ (khâao-sawy gài khráp), chicken khao soi. The sides arrive automatically.
A2 Make it yours
Use the sides like a local: squeeze the lime, drop in some pickled greens and shallot, stir the chilli oil in gradually. Extra crispy noodles: ขอเส้นกรอบเพิ่มครับ.
B1 Talk about it
Compare north and centre out loud: ข้าวซอยเข้มกว่าแกงกลาง, khao soi is richer than central curries; note the Burmese-Yunnanese trade-road history and you are the interesting foreigner at the table.
C1 to native Own it
The Chiang Mai native's question is which SHOP, not which dish: everyone has a ร้านประจำ (ráan bprà-jam, regular shop) and defends it. Have one and name it, ผมกินเจ้านี้ประจำ, and you have graduated from tourist to resident.
