Ingredients for Khao Soi

The following ingredients will make a flavorful Thai coconut curry noodle soup that serves about 2–4 people, depending on portion size.

• 1 cup chicken broth or vegetable broth
• 4–6 kaffir lime leaves (optional but recommended)
• 1 red bell pepper, thinly sliced (or other vegetables)
• 2 tablespoons fish sauce or vegan fish sauce
• 2 tablespoons soy sauce (reduce if using vegan fish sauce)
• 2 tablespoons brown or palm sugar
• 1 tablespoon chili garlic sauce (Sambal Oelek)
• 8–12 ounces protein: prawns, crispy tofu, or thinly sliced chicken breast
• Salt and pepper to taste
• 1 lime, for squeezing

Garnishes

• Fresh basil (Thai basil ideal)
• Pickled mustard greens (traditional)
• Cilantro
• Bean sprouts
• Lime wedges

Optional Substitutions

• Gluten-free: use tamari instead of soy sauce.

How to Make Khao Soi – Step by Step

Step 1: Prepare the noodles

Place rice noodles in a large bowl or baking dish and cover with boiling water. Let them soften until al dente, stirring occasionally. Drain and toss with a little oil to keep them from sticking.

Step 2: Prepare aromatics and protein

While the noodles soak, prep your protein (prawns, chicken, or tofu). Finely dice the shallot, chop the garlic and lemongrass, and slice the red bell pepper.

Step 3: Cook the curry base

Heat oil in a large pot over medium heat. Add shallot, garlic, and lemongrass and sauté until fragrant and softened, about 3–4 minutes. Stir in the red curry paste, turmeric, yellow curry powder, and cardamom, cooking another minute to bloom the spices.

Step 4: Build the soup

Add the coconut milk, broth, and kaffir lime leaves to the pot. Stir and bring to a gentle simmer. Add the sliced bell pepper, fish sauce, soy sauce, brown sugar, and chili garlic paste. Simmer briefly to combine flavors.

Step 5: Add the protein

Gently add your chosen protein and simmer until cooked through: prawns typically need 3–5 minutes; thinly sliced chicken will finish in a few minutes as well; tofu should be heated through.

Step 6: Final adjustments

Squeeze in lime juice and taste. Adjust seasoning with salt, pepper, extra fish sauce, sugar, or curry paste to balance salty, sweet, sour, and spicy notes.

Step 7: Assemble the bowls

Divide noodles among serving bowls and ladle the hot curry broth over them so each portion receives protein and vegetables.

Step 8: Garnish and serve

Top each bowl with your preferred garnishes—Thai basil, pickled mustard greens, crispy noodles, bean sprouts, cilantro, sliced onions, and lime wedges. Serve immediately while hot.

Helpful Tips

• Use fresh aromatics—lemongrass, garlic, and kaffir lime leaves elevate the dish.
• Adjust spice level to taste by varying red curry paste and chili sauce.
• Prepare the soup base a day ahead; flavors deepen overnight.

Cooking Tips for the Best Khao Soi

• Choose full-fat coconut milk for a creamy, rich broth.
• Keep the soup at a gentle simmer to avoid breaking the coconut milk and altering the texture.
• Serve generous garnishes for contrast: crunchy, bright, and fresh elements make each bite more interesting.

Serving Suggestions

Enjoy Khao Soi on its own as a complete bowl meal, or pair it with a light cucumber salad or steamed jasmine rice. A cold Thai iced tea or a crisp white wine can complement the rich coconut curry flavors.
