Description

A creamy, aromatic Thai soup made with chicken, mushrooms, and a fragrant coconut broth infused with lemongrass, galangal, and kaffir lime leaves, finished with lime and cilantro.


Ingredients

3 cups chicken broth

1 can (13.5 oz) full‑fat coconut milk

2 stalks lemongrass, trimmed and smashed

46 slices galangal (or ginger if unavailable)

56 kaffir lime leaves, torn

1 cup cooked chicken breast or thigh, thinly sliced

1 cup mushrooms (straw or button), sliced

1 small red chili or Thai bird’s eye chili, halved

2 tbsp fish sauce

1 tbsp lime juice

1 tsp palm sugar or brown sugar

Fresh cilantro, chopped, for garnish

Scallions, thinly sliced, for garnish

Lime wedges, for serving


Instructions

  1. In a soup pot, combine chicken broth and coconut milk. Add lemongrass, galangal, and kaffir lime leaves.
  2. Bring to a gentle simmer over medium heat and cook for 10–15 minutes to infuse the broth.
  3. Add sliced mushrooms and chili. Simmer for 5 minutes until mushrooms soften.
  4. Add cooked chicken and simmer for 2–3 minutes to heat through.
  5. Stir in fish sauce, lime juice, and sugar. Taste and adjust seasoning as needed.
  6. Remove lemongrass, galangal, and lime leaves with a slotted spoon.
  7. Ladle soup into bowls and garnish with cilantro and scallions. Serve with lime wedges.

Notes

  • Use ginger if galangal is unavailable.
  • To make vegetarian, substitute tofu and vegetable broth.
  • Full-fat coconut milk gives the richest flavor and texture.
  • Do not boil vigorously—keep a gentle simmer to preserve flavors.
  • Add fresh lime juice just before serving to keep it tangy.
