This is the dish that makes people stop mid-conversation and say “this is sooo good!”. The one that turns first-timers into obsessives. The creamy coconut curry broth with soft noodles swimming in golden broth, topped with a tangle of crispy fried noodles for crunch. It's comfort food that somehow feels elegant.
And yet, despite being one of Northern Thailand's most iconic dishes, Khao Soi remains relatively unknown outside of Thai food circles. Which, honestly, is a crime. Let's fix that.

The Origins: A Dish Born from Cultural Exchange
Khao Soi (ข้าวซอย) hails from Chiang Mai and the surrounding northern regions, but its roots stretch across borders. The dish shows the influence of Burmese and Chinese Muslim traders who traveled through Northern Thailand, bringing with them a love of rich curries and wheat noodles.
The result is something uniquely Thai – a curry that's creamier than most Thai curries, served with egg noodles instead of rice, and finished with those addictive crispy noodles on top that give it textural contrast.
In Chiang Mai, you'll find Khao Soi everywhere. Street vendors serve it from dawn until late at night. Locals have fierce debates about which stall makes the best version. Tourists try it once and spend the rest of their trip seeking it out.
The Flavour Profile: Creamy Comfort with Depth
What sets Khao Soi apart from other Thai curries is its uniquely layered flavour profile.
The base is a rich coconut curry – creamy, warming, and aromatic with spices like turmeric, coriander, cardamon, star anise and cumin, just to name a few.
Warming spices give it complexity without overwhelming heat. This isn't a blow-your-head-off spicy curry – it's more gentle and inviting, with just enough chilli to give it character. Think of it as a 2 out of 5 on the heat scale. To some, this might be a gentle tickle to others it may have a kick of spice.
The coconut milk makes the broth silky and luxurious, while a touch of palm sugar adds savoury-sweet depth. Some versions include pickled mustard greens as a garnish for a sour, funky note that cuts through the richness but my daughters opt for a garnish of chopped shallots and coriander to keep things light and fresh.
Then comes the genius part: crispy fried noodles on top. As they sit in the hot broth, some soften while others stay crunchy, giving you different textures in every spoonful. It's the detail that makes Khao Soi unforgettable.
Why It's Easier Than You Think
Traditional Khao Soi requires making a curry paste from scratch – roasting spices, pounding aromatics, and balancing flavours. It's time-consuming and requires ingredients that aren't always easy to find outside of Thailand.
But here's the wonderful secret: Khao Soi is incredibly straightforward when you have the paste ready to go.
The cooking method is simple. You bloom the paste in a bit of oil to wake up the aromatics, add coconut milk and stock, simmer your protein until cooked through, and serve over noodles with toppings. Start to finish, you're looking at about 30 minutes total or 40 minutes if it’s your first go at it.
Our Khao Soi paste has all those hard-to-find northern Thai spices already balanced and ready. We've done the roasting, the grinding, the tasting and adjusting, so you can go straight to the good part – ladling creamy, golden curry over noodles and watching it disappear.
Make It Your Own
Khao Soi is traditionally made with chicken or beef, but it's wonderfully adaptable.
Chicken thighs are classic – they stay tender in the curry and soak up all that flavour. Beef shin or brisket gives you something richer and more substantial (just braise it longer until it's fall-apart tender). Prawns work beautifully for a quicker version. Tofu or mushrooms make an excellent vegetarian option that's just as satisfying.
The toppings are where you get to play. Crispy fried noodles are non-negotiable – they're what makes Khao Soi, well, Khao Soi. Beyond that, add:
-
Pickled mustard greens for sour funkiness
-
Fresh lime wedges for brightness
-
Sliced shallots for crunch and sharpness
-
Fresh coriander for herbal freshness
-
Chilli oil or fresh chillies if you want more heat
Some people like to add a hard-boiled egg. Others throw in some pak choi or spring onions. There's no wrong answer.
So now you don't have to travel to Chiang Mai or hunt down one of London's few Northern Thai restaurants to experience it. You can make it at home, in less time than it takes to order takeaway.
