Khao Soi
ข้าวซอย
Khao Soi is northern Thailand's signature dish — egg noodles in a rich, curried coconut milk broth, topped with crispy fried noodles, pickled mustard greens, and shallots. It's a Burmese-influenced dish unique to Chiang Mai and the north.
Cultural Origin
Khao soi is a coconut-curry noodle soup from Northern Thailand, particularly Chiang Mai and Chiang Rai, with strong Burmese-Shan and Yunnanese-Muslim influences carried along historic caravan trade routes. The dish combines a turmeric-tinted coconut curry broth with both boiled and crispy egg noodles, typically over chicken or beef, served with pickled mustard greens, shallots and lime. It is the signature dish of Lanna cuisine and remains rare outside the north in its authentic form.
Regional Variants
| Region | How it differs |
|---|---|
| Northern | The Chiang Mai version is the classic: coconut curry broth, turmeric, chicken or beef, topped with crispy egg noodles, shallot, pickled greens and lime. |
| Southern | Khao soi in the south (rarely seen) tends to be more curry-like and less sweet, sometimes made without crispy noodles. |

Key Ingredients
- egg noodles
- coconut milk
- red curry paste
- chicken drumstick
- crispy noodles
Taste profile
- Salty
- fish sauce, soy, shrimp paste
- Sweet
- palm sugar, coconut
- Sour
- lime, tamarind, fermentation
- Umami
- dried shrimp, fermented pastes, stock
Rich and rounded from coconut milk and curry paste rather than sharp in any one direction; the lime and pickled mustard greens added at the table are what introduce the sourness and cut the fat, so an untouched bowl tastes noticeably sweeter and heavier.
How Khao Soi Is Made
- 1
Curry base
A red curry paste built on dried chillies, shallot and spices is fried in coconut cream until the oil separates, the traditional sign that the paste is cooked through rather than raw.
- 2
Broth
Coconut milk and stock are added to the fried paste and simmered slowly, usually with chicken on the bone, so the meat flavours the broth as it cooks rather than being added afterwards.
- 3
Noodles
Fresh egg noodles are boiled to order and dropped straight into the bowl of curry broth.
- 4
Crispy topping
A handful of the same egg noodles is deep-fried separately until brittle and piled on top, giving the one bowl two textures of the same noodle.
- 5
Garnish
Sliced shallot, pickled mustard greens and a lime wedge are served alongside rather than mixed in, so the diner controls how sharp and sour the final bowl becomes.
When It’s Eaten
A one-bowl meal eaten at any point in the day in Chiang Mai and the north, most often for lunch; it is filling enough that it is rarely paired with side dishes beyond the table condiments.

What people get wrong
Stirring the crispy noodle topping in immediately — it is meant to stay crunchy for the first few bites before it softens into the broth, so mixing it straight away wastes the textural contrast that makes the dish distinctive.
Where to Try It
Khao Soi Khun Yai and Khao Soi Lam Duan in Chiang Mai are the city's most celebrated spots.
Tips
- Squeeze lime and add pickled mustard greens from the condiment plate — these cut through the rich coconut broth perfectly.
- The crispy noodles on top are fried versions of the soft noodles in the bowl — don't skip them.
