Thai Khao Soi with Coconut Curry Broth, Egg Noodles, Braised Chicken and Crispy Fried Noodle Topping

Make the khao soi paste: in a mortar or blender, combine the soaked dried chilies, shallots, garlic, ginger, galangal, and lemongrass. Pound or blend to a rough paste. Add toasted shrimp paste, turmeric, coriander, and cumin. Continue pounding until a cohesive, fragrant paste forms. If using a blender, add a splash of coconut milk to help it blend smooth.

Ingredients

• For the khao soi paste:
• 4 dried long red chilies, soaked in hot water 15 minutes, seeds removed for milder heat
• 2 dried bird's eye chilies
• 5 shallots, roughly chopped
• 6 garlic cloves
• 2cm piece fresh ginger
• 2cm piece fresh galangal (or substitute extra ginger, though galangal has a distinct piney, citrusy flavor that ginger cannot perfectly replicate)
• 2 stalks lemongrass, bottom 10cm only, outer layers removed, roughly sliced
• 1 tsp ground turmeric (gives khao soi its characteristic golden-yellow color)
• 1 tsp ground coriander
• 1/2 tsp ground cumin
• 1 tsp shrimp paste (gapi) — wrap in foil and toast in a dry pan for 1 minute per side
• For the curry broth:
• 400ml (1.5 cups) full-fat coconut milk, divided (use the thick cream from the top separately)
• 600ml (2.5 cups) chicken stock
• 3-4 bone-in, skin-on chicken thighs (about 600g / 1.3 lbs)
• 2 tbsp fish sauce (nahm pla), plus more to taste
• 1 tbsp palm sugar or brown sugar
• For the noodles:
• 300g (10.5 oz) fresh egg noodles (ba mee) — thick wheat noodles similar to ramen; dried ramen noodles are an acceptable substitute
• For the crispy noodle topping:
• 100g (3.5 oz) fresh egg noodles, loosened into small tangles
• Neutral oil for deep-frying
• For serving (all essential — khao soi without condiments is incomplete):
• 2 shallots, thinly sliced
• Pickled mustard greens (pak gaat dong), roughly chopped — the sour crunch is the essential counterpoint to the rich coconut curry
• Fresh lime wedges
• Sliced fresh red chilies in fish sauce (phrik nahm pla)

Instructions

1. Make the khao soi paste: in a mortar or blender, combine the soaked dried chilies, shallots, garlic, ginger, galangal, and lemongrass. Pound or blend to a rough paste. Add toasted shrimp paste, turmeric, coriander, and cumin. Continue pounding until a cohesive, fragrant paste forms. If using a blender, add a splash of coconut milk to help it blend smooth.
2. Make the crispy noodle topping: heat 5cm of neutral oil in a small saucepan to 180°C (355°F). Carefully lower small tangles of fresh egg noodles into the hot oil. Fry for 2-3 minutes, turning once, until deep golden and very crispy. Drain on paper towels. The crispy noodles are not optional — they provide the textural contrast that defines khao soi. Season lightly with salt.
3. Crack the coconut milk: open the can without shaking. Scoop the thick cream from the top (about 4-5 tablespoons) into a wide pot or wok. Heat over medium heat, stirring, until the cream begins to bubble and the oil separates — the coconut cream will look slightly curdled, which is correct. This is called 'cracking' the coconut milk and is the essential technique for properly developing the paste.
4. Fry the paste: add the khao soi paste to the cracked coconut cream. Fry, stirring constantly, for 5-7 minutes until the paste darkens slightly and the raw aromatic smell becomes deeply complex and mellow. Rushing this step produces a raw, sharp-tasting curry. The paste is ready when it smells caramelized and profound, not harsh.
5. Add chicken and liquid: add chicken thighs skin-side down. Sear briefly in the paste for 2 minutes. Add remaining coconut milk and chicken stock. Bring to a gentle boil. Add fish sauce and palm sugar. Reduce heat to a low simmer and cook, uncovered, for 35-40 minutes until the thighs are fully cooked. Remove the chicken, pull the meat from the bones in large chunks, and return meat to the broth. Taste — adjust with fish sauce for saltiness, palm sugar for sweetness.
6. Cook the noodles: bring a large pot of unsalted water to a boil. Cook fresh egg noodles according to package directions — usually 3-4 minutes. Drain. Divide noodles into bowls.
7. Assemble and serve: ladle the coconut curry broth generously over the noodles. Arrange large pieces of pulled braised chicken on top. Pile the crispy fried noodles prominently on top — they should be visible and abundant, crowning the bowl. Arrange sliced shallots, pickled mustard greens, and lime wedges around the bowl. Serve with fish sauce, sliced chilies, and additional lime. Khao Soi (ข้าวซอย) is the signature dish of Chiang Mai and the broader Lanna kingdom of northern Thailand. Its Muslim Chinese-Burmese origins — brought by caravans through the Golden Triangle trade routes — are reflected in its curry-noodle format, which differs completely from the broth-based curries of central Thailand.
