Khao soi is the signature dish of northern Thailand: soft boiled egg noodles in a rich, mildly spiced coconut curry broth, topped with a tangle of crispy fried noodles, and served with chicken or beef on the bone. It comes with sides of pickled mustard greens, sliced shallots, and lime to adjust as you eat. Its roots are Yunnanese-Muslim, and it is milder and more aromatic than most Thai curries. It is the first thing to eat in Chiang Mai.

Where is the best khao soi in Chiang Mai?

There is no single best, and locals argue happily about it. Long-standing favourites include Khao Soy Mae Sai, Khao Soi Khun Yai (a lunch-only spot that sells out early), Khao Soi Lung Prakit, Khao Soi Islam (halal, with a Muslim-Thai menu), and Khao Soi Mae Manee. Each has its own balance of broth richness and spice. Try two or three and pick your favourite; that is the fun of it.

What is the difference between northern Thai food and regular Thai food?

Northern Thai (Lanna) food is milder, earthier, and more herb-driven than central or southern Thai, with strong Burmese and Yunnanese influences. Sticky rice is the staple instead of jasmine rice, coconut milk is used less, and the cuisine centres on grilled sausages, chili dips (nam prik) eaten with vegetables, slow-cooked curries like gaeng hang lay, and noodle soups. It is a cuisine of shared dips and communal eating rather than individual stir-fried plates.

Sai ua is northern Thai grilled herb sausage: minced pork packed with lemongrass, galangal, kaffir lime leaf, turmeric, chilies, and herbs, then coiled and grilled over charcoal. It is fragrant, slightly spicy, and one of the most beloved northern foods, sold at markets, roadside stalls, and restaurants. Buy it by weight at a market, eat it with sticky rice and a chili dip, and you have the essence of Lanna food in one bite.

What are nam prik num and nam prik ong?

They are the two essential northern chili dips. Nam prik num is made from roasted green chilies, garlic, shallots, and coriander pounded into a smoky, medium-hot relish. Nam prik ong is a milder, sweeter dip of minced pork and tomatoes simmered with chilies, almost like a Thai bolognese. Both are eaten by dipping sticky rice, steamed and raw vegetables, and pork crackling, and they appear on almost every northern Thai table.

What is gaeng hang lay?

Gaeng hang lay is a rich, slow-cooked northern pork curry of Burmese origin, made with pork belly, ginger, garlic, tamarind, and a special hang lay curry powder rather than coconut milk. It is mild, sweet-sour, and deeply savoury, often considered a special-occasion dish. It is excellent with sticky rice and is a great entry point for anyone who finds Thai food too spicy, since it carries flavour rather than heat.

When should I eat northern Thai food, and do places close early?

Many of the best northern Thai and khao soi spots are daytime, lunch-focused places that open mid-morning and sell out by early to mid-afternoon, so go for lunch rather than dinner if you can. Khao Soi Khun Yai is a classic example, often gone by 2pm. Market and street versions run into the evening, and full-service restaurants like Huen Phen serve dinner. When in doubt, eat northern Thai for lunch.

Is northern Thai food very spicy?

It varies by dish. Khao soi, gaeng hang lay, and sai ua are mild to moderate; the chili dips (especially nam prik num) and northern larb can be genuinely hot. The good news is you control much of it: dips are added to taste, and you can ask for dishes 'mai phet' (not spicy) or 'phet nit noi' (a little spicy). Northern food is more about herbal depth than raw chili heat, so even spice-shy eaters find plenty to love.

Khao Soi & Northern Thai Food in Chiang Mai (2026): Dishes & Best Spots

The complete guide to Lanna cuisine: khao soi, sai ua, the chili dips, gaeng hang lay, khanom jeen nam ngiao, and northern larb, with the best place to eat each one. What every dish is, how to order, and the institutions locals actually go to.

To eat in Chiang Mai is to eat the food of the old Lanna kingdom: a northern Thai cuisine shaped by mountains, trade routes, and centuries of Burmese and Yunnanese influence. It is milder than the Thai food most visitors know, built on herbs, fermented chilies, grilled sausages, and shared dips eaten by hand with sticky rice. This guide is the one to read before you order: every essential dish, what it is, how to eat it, and the place locals actually go for the best version.

Khao soi: start here

If you eat one thing in Chiang Mai, eat khao soi. Soft egg noodles sit in a fragrant, mildly spiced coconut curry, crowned with a nest of crispy fried noodles, with chicken or beef on the bone. Alongside come pickled mustard greens, sliced shallots, and a wedge of lime, which you add as you go to brighten and sharpen each spoonful. Its origins are Yunnanese-Muslim, which is why it tastes unlike a central Thai curry: aromatic and rich rather than fiery.

Where to eat it

Khao Soy Mae Sai: A long-running favourite, consistently excellent, one of the most popular in the city.
Khao Soi Khun Yai: A beloved lunch-only spot behind a temple, famous for selling out by early afternoon. Go early.
Khao Soi Lung Prakit: A local institution with a rich, well-balanced broth.
Khao Soi Islam: Halal, near the mosque, with a broader Muslim-Thai menu of curries and roti alongside the khao soi.
Khao Soi Mae Manee: Another well-regarded local spot worth seeking out.

The move is to try two or three over a few days and pick your own favourite. No two broths are quite the same.

Sai ua: the herb sausage

Sai ua is northern Thailand in a single bite: minced pork packed with lemongrass, galangal, kaffir lime, turmeric, chilies, and herbs, coiled into a spiral and grilled over charcoal until fragrant and a little charred. Buy it by weight at any market (Warorot is ideal), eat it with sticky rice and a chili dip, and you understand Lanna food. It is sold everywhere, from market stalls to restaurants, and it travels well as a snack.

The chili dips: nam prik

Northern meals revolve around nam prik, chili relishes eaten by dipping sticky rice, vegetables, and pork crackling. The two essentials:

Nam prik num: Roasted green chilies, garlic, and shallots pounded into a smoky, medium-hot dip. The northern classic.
Nam prik ong: A milder, sweeter dip of minced pork and tomato simmered with chilies, almost like a Thai ragu. Approachable for everyone.

They arrive with a platter of steamed and raw vegetables and cap moo (crispy pork crackling) for scooping. Do not skip them; they are the heart of a northern table.

Gaeng hang lay: the Burmese curry

Gaeng hang lay is a slow-cooked pork belly curry of Burmese origin, made with ginger, garlic, tamarind, and a distinctive hang lay spice blend rather than coconut milk. It is rich, sweet-sour, and savoury, with almost no heat, which makes it a perfect dish for anyone who finds Thai food too spicy. Eat it with sticky rice. It is often a special-occasion dish and appears on most good northern Thai menus.

Khanom jeen nam ngiao and northern larb

Khanom jeen nam ngiao: Fresh rice noodles in a tangy tomato-and-pork broth flavoured with dried cotton-tree flowers and pork blood, topped with herbs and crispy garlic. A market and breakfast favourite, light and tangy.
Larb muang: Northern larb differs from the Isaan version most people know. It is a dry, intensely spiced minced-meat salad bound with a dark blend of roasted spices (and sometimes blood), without lime or fish sauce. Earthy, herbal, and genuinely hot. Order it where locals do.

The institutions

For the full northern Thai canon in one sitting:

Huen Phen: The Old City institution. A bustling market-style operation at lunch and an atmospheric antique-filled restaurant at dinner, covering all the classics.
Tong Tem Toh: A popular, characterful northern Thai restaurant in Nimman, great for a first deep dive into the cuisine.
Dash! Teak House: A handsome teak-house restaurant in the Old City with a solid northern and Thai menu.
Nong Bee's Burmese Restaurant: For the Burmese side of the region's food, tea-leaf salad and all.

A first-timer's order

For a table of two to four, order: one khao soi each, a plate of sai ua, nam prik num or nam prik ong with the vegetable platter and cap moo, a gaeng hang lay, and a basket or two of sticky rice. Add a northern larb if you like heat. That is a complete, classic Lanna meal, and it will cost very little.

The bottom line

Northern Thai food is one of the best reasons to come to Chiang Mai, and it is easy to eat well once you know the dishes. Make khao soi your first meal, work through the dips and the sausage and the slow curry, and eat northern food at lunch when the specialists are at their best. Then explore the street food, the vegetarian scene, and a cooking class to learn it yourself.
