Ingredients
  

  • 1 tablespoon coconut oil or vegetable oil
  • 3 cups chicken broth
  • 1 stalk lemongrass cut into 2-inch pieces and smashed
  • 4 –5 slices galangal or ginger, if unavailable
  • 3 kaffir lime leaves torn in half
  • 1 14 oz can coconut milk
  • 1 pound boneless skinless chicken breast or thighs, thinly sliced
  • 1 cup mushrooms sliced (shiitake or button)
  • 2 –3 Thai chilies smashed (optional, to taste)
  • 2 tablespoons fish sauce or to taste
  • 1 tablespoon sugar
  • 2 tablespoons lime juice or to taste
  • Fresh cilantro chopped (for garnish)
  • Lime wedges for serving

Instructions
 

  • Infuse the Broth: In a large pot, heat the coconut oil over medium heat. Add chicken broth, lemongrass, galangal, and kaffir lime leaves. Simmer for 5–7 minutes to infuse the flavors.
  • Add Coconut and Chicken: Stir in the coconut milk and bring to a gentle simmer. Add the sliced chicken and cook for 5–7 minutes, until just cooked through.
  • Add Mushrooms and Season: Add mushrooms and Thai chilies (if using). Stir in fish sauce and sugar. Simmer for another 5–7 minutes.
  • Finish with Lime: Remove from heat. Stir in lime juice and adjust seasoning with more fish sauce or lime juice to taste.
  • Serve: Ladle into bowls and garnish with chopped cilantro. Serve with lime wedges on the side.

Notes

  • For a vegetarian version, use tofu instead of chicken and soy sauce in place of fish sauce.
  • Galangal and kaffir lime leaves can be found at Asian grocery stores or substituted if necessary.
  • Remove lemongrass, galangal, and lime leaves before serving—they are used for flavor but not eaten
