Curry Noodle Soup
Khao Soy Gai: Northern Thai Curry Noodles with Chicken
Original name: Khao Soy Gai (Northern Curry Noodles)

About this dish
Khao soy gai is Chiang Mai's signature bowl: soft egg noodles bathed in a rich, coconut-enriched curry broth, topped with crunchy fried noodles, pickled greens, and a squeeze of lime. The dish blends Northern Thai, Shan, and Burmese culinary influences, with a broth built on dried chiles, warm spices, and fermented shrimp paste for deep umami.
At home, you can nail the balance of creamy and tart by making a quick curry paste and frying your own noodle nest. It's a weeknight-flexible bowl that tastes like a market stall.

Method
Soak and blend the curry paste
PT20MSoak dried chiles in hot water for 15 minutes, then drain. In a blender or mortar, combine soaked chiles, lemongrass, galangal, turmeric, garlic, shallots, shrimp paste (if using), coriander, and cardamom. Blend or pound to a smooth, thick paste, adding a splash of water if needed.
Fry the paste
PT5MHeat 2 tbsp of the thick coconut cream (from the top of the can) in a large pot over medium heat. Add the curry paste and fry, stirring constantly, until fragrant and darkened, about 3-4 minutes. This step blooms the spices and removes raw flavor.
Build the broth
PT25MPour in the remaining coconut milk and chicken stock. Stir to combine and bring to a gentle simmer. Add fish sauce and palm sugar. Simmer uncovered for 20 minutes to meld the flavors.
Poach the chicken
PT10MAdd the chicken thigh pieces to the simmering broth. Cook gently for 10-12 minutes until cooked through and tender. Taste and adjust seasoning with more fish sauce or sugar. Keep warm.
Cook and fry the noodles
PT15MWhile the broth simmers, bring a pot of water to a boil. Cook half the egg noodles according to package instructions until just tender, then drain and set aside. Separate the remaining noodles into small nests. Heat oil in a wok or deep pan to 180°C (350°F). Fry the noodle nests in batches until golden and crispy, about 30-45 seconds per side. Drain on paper towels.
Assemble the bowls
PT5MDivide the boiled noodles among four deep bowls. Ladle the hot curry broth and chicken over the noodles. Top each bowl with a generous cluster of crispy fried noodles. Garnish with sliced shallots, pickled mustard greens, cilantro, and a lime wedge. Serve with chili oil on the side.

Tips
- Fry your curry paste in coconut cream until it's thick and fragrant, this step is key for a deep, rounded broth. Don't rush it.
- For the crispiest noodle nest, fry the noodles in small, loose bundles so they cook evenly and stay crunchy. Drain well on paper towels and keep them separate until serving.
- Khao soy gai is traditionally served with pickled mustard greens and lime to cut through the richness. Add them to taste at the table, not in the kitchen, so each diner can balance their bowl., The broth tastes even better the next day, make it ahead and refrigerate for up to 3 days. Fry the noodles fresh just before serving so they stay crisp.
Serving suggestions
- Serve with a side of extra lime wedges, pickled mustard greens, and roasted chili oil so everyone can adjust their bowl.
- Pair with a light cucumber salad or Thai pickled vegetables to balance the rich, creamy broth.
- For an optional kick, offer chopped fresh bird's eye chiles or a spoonful of nam prik pao.
