Khao Soi

Khao soi is northern Thailand's legendary curry noodle soup — silky coconut-turmeric broth ladled over egg noodles, crowned with a tangle of shatteringly crisp fried noodles. With pickled mustard greens, lime, and shallots on the side, every bowl is a build-your-own adventure.

Ingredients
- 600 g (1 1/4 lb) chicken drumsticks or thighs
- 400 ml (14 oz) coconut milk
- 3 tablespoons khao soi or red curry paste
- 1 tablespoon curry powder
- 1/2 teaspoon ground turmeric
- 500 ml (2 cups) chicken stock
- 1 tablespoon fish sauce, plus more to taste
- 1 tablespoon palm sugar
- 400 g (14 oz) fresh egg noodles, divided
- 500 ml (2 cups) vegetable oil, for frying
- 100 g (1 cup) pickled mustard greens, chopped
- 1 red onion or 2 shallots, diced
- 1 lime, cut into wedges
- Chili oil and chopped coriander, to serve
Instructions
- Fry the crispy noodle topping first: heat the oil to 175°C (350°F). Fry small handfuls of egg noodles (about 100 g) for 20–30 seconds until puffed and golden. Drain on paper towels and salt lightly.
- Spoon the thick coconut cream from the top of the can into a large pot. Fry 2 minutes until the oil separates.
- Add the curry paste, curry powder, and turmeric; fry 2 minutes until intensely fragrant.
- Add the chicken pieces and toss to coat. Pour in the remaining coconut milk and the chicken stock.
- Stir in the fish sauce and palm sugar. Simmer 20–25 minutes until the chicken is fall-off-the-bone tender.
- Meanwhile, boil the remaining egg noodles until just tender, then drain.
- Taste the broth — it should be rich, golden, and balanced between salty, sweet, and gently spicy. Adjust fish sauce and sugar.
- Divide the boiled noodles among deep bowls and ladle over the hot broth and chicken.
- Top each bowl with a handful of crispy noodles. Serve with pickled mustard greens, diced onion, lime wedges, and chili oil on the side.
Pro tips
- Fry the crispy noodles just before serving — they lose their crunch within an hour.
- Drumsticks give the richest broth, but thighs work if you prefer boneless.
- The broth should be thinner than a Western curry — more like a rich soup.
- Pickled mustard greens are non-negotiable; their sour crunch cuts the richness perfectly.
Frequently asked questions
What does khao soi taste like?
A golden, gently spiced coconut broth — milder than southern Thai curries — with soft noodles, crispy noodle crunch, and bright, pickly toppings. Comforting but never boring.
Can I make khao soi ahead?
Make the broth a day ahead — it improves overnight. Cook the noodles fresh and fry the crispy topping just before serving.
Where can I find khao soi paste?
Asian grocery stores stock it, or use red curry paste plus an extra teaspoon of curry powder and turmeric — the flavor lands very close.
Is khao soi spicy?
The broth itself is mild. Heat comes from the chili oil served alongside, so each person controls their own fire.
