Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
2 tablespoons vegetable oil
2 stalks lemongrass, trimmed and cut into 2-inch pieces
4 slices galangal (or ginger as a substitute)
4 kaffir lime leaves, torn
2 cloves garlic, minced
1 small onion, sliced
300 g chicken breast, thinly sliced
400 ml coconut milk
500 ml chicken broth
200 g mushrooms, sliced
2 tablespoons fish sauce
1 tablespoon sugar
2 tablespoons lime juice
1–2 fresh red chilies, sliced (adjust to taste)
2 tablespoons fresh cilantro, chopped
Directions
Start by heating the vegetable oil in a large pot over medium heat. Add the lemongrass, galangal, kaffir lime leaves, garlic, and onion. Sauté gently for about 2–3 minutes until the mixture becomes fragrant.
Pour in the chicken broth and bring it to a gentle simmer. Let the herbs infuse the broth for about 10 minutes, allowing their flavors to fully develop.
Add the sliced chicken to the pot and cook for about 5–7 minutes, or until the chicken is fully cooked and tender.
Stir in the coconut milk and mushrooms. Let the soup simmer gently for another 5 minutes, ensuring the mushrooms soften and the flavors blend well.
Season the soup with fish sauce, sugar, and lime juice. Taste and adjust seasoning as needed to achieve a balance of salty, sour, and slightly sweet flavors.
Add the sliced chilies for heat and let them cook briefly. Remove the pot from heat and garnish with fresh cilantro before serving.
Servings and timing
This recipe yields approximately 4 servings. Preparation time is about 15 minutes, and cooking time is around 25 minutes, making the total time roughly 40 minutes.
Variations
You can easily customize this soup based on your preferences. Swap chicken for shrimp to create a seafood version with a slightly sweeter taste. For a vegetarian option, replace chicken with tofu and use vegetable broth instead of chicken broth. If galangal is hard to find, ginger works as a practical alternative, though the flavor will be slightly different. Adding extra vegetables like bell peppers or baby corn can make the soup more filling. You can also increase or reduce the chili depending on your spice tolerance.
Storage/Reheating
Store any leftover soup in an airtight container in the refrigerator for up to 3 days. When reheating, warm it gently over medium-low heat on the stovetop to prevent the coconut milk from separating. Stir occasionally until heated through. Avoid boiling the soup during reheating, as this can affect the texture and flavor. Freezing is possible, but the coconut milk may slightly change consistency after thawing.
FAQs
