I have a core food memory that is etched in fire and coconut. It’s from a trip to Chiang Mai, sitting on a wobbly plastic stool, sweat beading on my forehead not from the heat, but from the perfect, aching spice of a bowl of Khao Soi. The air was thick with the scent of frying noodles and curry paste. I remember the sound—the crisp crackle of the deep-fried noodle topping giving way to the soft, slurpable noodles beneath, all swimming in that golden, aromatic broth. I must have tried to recreate it a dozen times at home, always missing the mark. It was either too sweet, too thin, or just… flat. The breakthrough came when I stopped using store-bought curry paste and embraced the mortar and pestle. I know, it’s a commitment. But grinding those fresh aromatics releases their essential oils in a way a food processor just can’t. This recipe is my love letter to that memory. It’s a project, but oh, what a glorious, soul-satisfying project it is.

Let’s Make It
First, let’s make the heart and soul of this dish: the curry paste. If you have a granite mortar and pestle, now is its time to shine. If not, a small food processor will work, but pulse, don’t run it continuously—you want a coarse paste, not a smooth purée. Start by toasting the coriander and cumin seeds in a dry pan over medium heat until fragrant, about 1-2 minutes. Pound them in the mortar to a fine powder. Then, add the soaked chilies, shallots, garlic, galangal, lemongrass, and cilantro roots. Pound, pound, pound until you have a fairly smooth, fragrant paste. It will take some elbow grease. Work in the turmeric and shrimp paste last. The smell will be absolutely transportive.
Now, let’s build the curry. In a large, heavy-bottomed pot or Dutch oven, heat the coconut oil over medium heat. Scoop out the thick cream from the top of the can of coconut milk and add it to the pot. Let it cook for a few minutes until it sizzles and the oils start to separate. Add your fresh curry paste and the tablespoon of curry powder. Fry this mixture, stirring constantly, for 4-5 minutes until it’s deeply aromatic and the raw smell of the shallots and garlic has cooked out.
Add the chicken thighs, skin-side down, and sear them for 2-3 minutes to render some of the fat and give them color. Flip them over, then pour in the remaining coconut milk and the chicken broth. Bring to a gentle simmer, then reduce the heat to low, partially cover, and let it cook for 35-40 minutes, until the chicken is fall-apart tender.
While the curry simmers, prepare the iconic crispy noodle topping. Take about a quarter of your total noodles (if using dried, no need to cook them first). Heat about 1.5 inches of oil in a small pot to 350°F (175°C). Carefully drop small handfuls of the dry noodles into the hot oil. They will puff up and crisp up almost instantly—it takes just 20-30 seconds. Remove with a slotted spoon and drain on a paper towel-lined plate. Season them with a tiny pinch of salt. They are your edible spoons, your crunchy delight.
Remove the cooked chicken from the broth and set it aside to cool slightly. Once cool enough to handle, shred the meat, discarding the skin and bones. Skim off any excess oil from the top of the curry broth, then stir in the fish sauce and palm sugar. Taste it. It should be a beautiful balance of salty, sweet, and spicy. Adjust as needed. Add the shredded chicken back to the pot to warm through.
Cook the remaining noodles according to package directions in a separate pot of boiling water until al dente. Drain well.

Variations & Add-Ins
- Vegetarian Delight: Swap the chicken for fried tofu puffs and use a rich vegetable broth. Omit the fish sauce and use soy sauce or vegan fish sauce.
- Beef Khao Soi: Use beef shank instead of chicken, simmering for 2-3 hours until meltingly tender.
- Extra Creamy: Use two cans of coconut milk and reduce the chicken broth by a cup for an intensely rich curry.
Serving Ideas
Place a nest of the soft, boiled noodles into each deep bowl. Ladle the fragrant curry and shredded chicken over the top. Now, the fun part: the toppings. Pile on the bean sprouts, sliced shallots, and a generous tablespoon of the pickled mustard greens. Place a majestic crown of the crispy fried noodles on one side. Finish with a squeeze of fresh lime juice and a sprinkle of cilantro. Serve immediately, with chili oil on the side for the brave.
Storage & Reheating
The curry (without noodles) stores beautifully. Let it cool and keep it in an airtight container in the fridge for up to 4 days, or freeze for 3 months. The flavors improve. Reheat gently on the stovetop. The crispy noodles will soften, so always make those fresh. The soft noodles are best cooked fresh, but you can store them cooked and rinsed with a little oil for 2 days.
My Two Cents
Do not skip the pickled mustard greens. I know they might require a trip to a specialty store, but they are the sine qua non of an authentic Khao Soi. Their sharp, salty, tangy crunch cuts through the rich coconut curry in a way that nothing else can. They are non-negotiable. If you can’t find them, a quick-pickle of finely chopped celery or cabbage with rice vinegar, sugar, and salt is a decent last-resort substitute.
You Asked, I’m Answering
“My curry paste is bitter! What happened?”
You likely burned the spices or the paste when you were frying it. The heat was too high. You want to fry it in the coconut cream until it’s fragrant and the oil separates, but if it starts to smoke or stick to the bottom of the pot, it’s gone too far. Low and slow is the key here.
“Can I use a store-bought curry paste?”
You can, but choose a Thai “Yellow Curry Paste” or a specific “Khao Soi Paste” if you can find it. You’ll need about ¼ cup. Still, fry it in the coconut cream as directed to wake up the flavors.
“My curry is too thin.”
Let it simmer uncovered for another 10-15 minutes to reduce and concentrate. You can also make a slurry with 1 tablespoon of cornstarch and 2 tablespoons of cold water and stir it in at the end to thicken it quickly.
