Khao Soi is a popular northern Thai curry recipe made with egg noodles cooked in coconut milk and an intensely flavorful curry paste of toasted chilies, ginger, cilantro, garlic, and more.
I have been enjoying curries of all types lately. Immensely. If you're a spicy food lover like I am - aka "total chilihead" - curry is where you need to be.
Curries are HUGE on flavor, filled with so many wonderful collections of spices and fresh ingredients. You may think curries are HOT, but the reality is that curry can range from mild to incredibly hot, all depending on your preference.
The one thing you CAN count on with every curry I've ever tried, however, is FLAVOR.
Like this particular curry - Khao Soi. It's amazing. Truly. With good heat!
What is Khao Soi Curry?
Khao Soi is a signature dish of Northern Thailand, served also in Laos and Myanmar. It's a coconut curry soup served with either rice or egg noodles.
Its name translates to “cut rice”, where large sheets of seasoned rice noodles are cut into fine flat noodles, cooked, then added to a creamy coconut broth infused with curry paste and other optional ingredients, depending on the cook.
It’s a heavily garnished curry soup, with all sorts of possible ingredients that, again, vary from cook to cook. More on that below.
For me, it all starts with the amazing curry paste that imbues this signature Northern Thai coconut curry soup with loads of flavor.
There are different ways to make Khao Soi, though this version is similar to Massaman curry in texture and flavor.
I’m making this with a homemade curry paste, though you can use a store bought curry paste – red or yellow, or a mixture of them - if you’d like in place of the dried peppers. You won’t get the exact same flavor, but it will still be tasty.
This recipe includes chicken thighs, as I love to cook with them, though you can use whole chicken legs, thighs and wings as well, with the bone. It’s also good with seafood, particularly shrimp and white fish.
A distinctive characteristic of this dish is the use of fried noodles as a garnish, which may sound a bit daunting, but in reality, it’s pretty simple to do. I’ve included it in the cooking directions below.
Let’s talk about how to make Khao Soi, shall we?
How to Make Khao Soi (Northern Thai Coconut Curry Soup) - the Recipe Method
First, make the fried noodles by heating the vegetable oil in a pot. Do not let it boil. Add 4 ounces of egg noodles and lightly fry them, stirring occasionally, until they brown and crisp up, about 3-4 minutes.
Set them onto paper towels to drain. You can reserve some of the oil to use later if you’d like.
Next, make the Khao Soi curry paste.
Heat a large pan to medium heat and dry toast your dried peppers, flipping here and there, until they become pliable.
Cool them slightly, then remove the stems and seeds. Place the peppers in a bowl and pour hot water over them. Soak them about 20 minutes, until they are nice and soft.
Next, add the peppers along with the shallot, garlic, ginger, cilantro, turmeric, curry powder, and about ¼ cup of the pepper soaking liquid to a food processor.
Process to form a paste. You can add in more soaking liquid if you need to.
To make the curry soup, heat a tablespoon of olive oil or coconut oil in a wok or large pan. Add the Khao Soi curry paste and cook it down, stirring often, for 5 minutes.
It will darken a bit.
Pour in the coconut milk, chicken broth, and add the chopped chicken.
Bring the mix to a boil, then reduce the heat and simmer for 30 minutes, until the chicken is cooked through and the flavors have nicely developed.
Remove from heat. Stir in the fish sauce, soy sauce and brown sugar. Adjust to taste with salt, fish sauce and soy sauce.
For serving, divide some prepared egg noodles into bowls, then pour the curry soup over them.
Garnish with fried egg noodles and more, then serve! More on the garnishments below.
About the Chili Peppers and Curry Paste
I used dried chiles de arbol and dried New Mexican chili peppers here to form the base of my Khao Soi curry paste, though other peppers can be used.
If you can obtain fresh Thai Chili Peppers, use those. You can obviously skip the rehydration step and use them as you use the other fresh ingredients.
Other options include guajillo peppers or California peppers, which may be easier for you to find in the U.S.
You can also skip the step of making your own curry paste and purchase a store bought red or yellow curry paste. Or buy both and use a combination of the two.
I would encourage you to make your own curry paste, however, as the flavors are more authentic.
Recipe Variations
I've seen other recipes that include kaffir lime leaves, as well as tamarind. I've opted to omit them, though feel free to use them when you add in the coconut milk.
Garnish Ingredients for Khao Soi
Khao soi is typically served with a number of garnishes, and the choice is yours what you'd like to include.
Popular ingredients include pickled greens, diced shallots, sliced red onions, bean sprouts, cilantro, scallions, drizzles of chili oil, fresh lime wedges, spicy chili flakes, and, of course, fried noodles.
If it gets TOO spicy, serve it alongside this Traditional Indian Raita recipe, which is made from spiced yogurt. It has a nice cooling effect.
About the Fried Noodles
The fried noodles are actually very easy to make. You fry them in vegetable oil whole, uncooked. They only take a few minutes to brown, and they crisp up nicely.
They're an excellent textural addition to the spicy, creamy soup. I wouldn't skip them.
That's it, my friends! I hope you enjoy your Khao Soi! Such an amazing Thai coconut curry! Soup doesn't get any better than this.

Jonah says
How many Thai chillies do you recommend using? I used 10 and my curry paste was very yellow and once the coconut milk was in the flavour was almost completely lost. the only thing I did differently was use 10 small thai chillies and it ended up tasting like a completely different soup than I expected.
Michael Hultquist - Chili Pepper Madness says
Much depends on your heat preference, Jonah. You can really add as many as you'd like. Maybe start with a couple, but if that's nothing for you, add in more. You might need extra curry paste as well.
Tisha says
Love the addition of the fried noodles on top for an added crunch!
