The secret to a great Tom Kha Gai lies in the quality of its aromatics. By gently simmering the broth with smashed lemongrass and torn lime leaves, you unlock essential oils that provide an incomparable depth of flavor. This soup is not just a meal; it is a sensory journey through the vibrant streets of Thailand.

Ingredients

• 3 cups (720 ml) chicken broth
• 1 stalk lemongrass, trimmed and smashed
• 4 slices fresh galangal (or substitute with ginger if unavailable)
• 4 makrut lime leaves, torn into pieces
• 3 Thai birds eye chilies, lightly crushed (adjust to taste)
• 1 lb (450 g) boneless, skinless chicken thighs, thinly sliced
• 14 oz (400 ml) coconut milk (full-fat, unsweetened)
• 5 oz (140 g) fresh mushrooms (straw mushrooms or cremini), sliced
• 1 medium shallot, thinly sliced
• 2 tbsp fish sauce
• 1 tbsp lime juice (plus more to taste)
• 1 tsp palm sugar (or brown sugar)
• 2 tbsp fresh cilantro, chopped
• 2 green onions, sliced
• Lime wedges, for serving

Instructions

Step 1: Infuse the Broth

In a medium pot, bring the chicken broth to a gentle simmer. Add lemongrass, galangal, makrut lime leaves, and chilies. Simmer for 5–7 minutes to infuse the broth with aromatics.

Step 2: Cook the Chicken

Add the sliced chicken and shallot. Cook for 3–4 minutes, until the chicken turns opaque.

Step 3: Add Coconut Milk and Mushrooms

Add the mushrooms and pour in the coconut milk. Stir gently and bring back to a simmer. Do not let it boil vigorously.

Step 4: Season

Season the soup with fish sauce, palm sugar, and lime juice. Adjust seasoning to taste, balancing salty, sour, and sweet.

Step 5: Final Prep

Remove from heat. Discard the lemongrass, galangal slices, and lime leaves if desired.

Step 6: Garnish and Serve

Ladle the soup into bowls. Garnish with cilantro, green onions, and serve with lime wedges.

Zusatztipps für die Zubereitung

To get the most out of your aromatics, ensure the lemongrass is well-smashed and the lime leaves are torn to release their fragrance. Be careful not to let the soup reach a rolling boil once the coconut milk is added, as this can cause the milk to separate and lose its smooth, creamy consistency.

Varianten und Anpassungen

For a vegetarian version, swap the chicken broth for vegetable broth, replace the chicken with firm tofu, and use soy sauce instead of fish sauce. You can also adjust the heat level by increasing or decreasing the number of Thai birds eye chilies used in the initial simmer.

Serviervorschläge

While this soup is delicious on its own, it is traditionally served with a side of steamed jasmine rice for a heartier meal. The rice perfectly absorbs the tangy coconut broth, making every bite satisfying and complete.

Q&A About the Recipe

→ Can I substitute galangal with ginger?

While ginger can be used as a substitute, galangal has a distinct citrusy, pine-like flavor that is essential for authentic Tom Kha Gai. If possible, seek out fresh or frozen galangal at Asian markets for the best results.

→ What type of mushrooms work best?

Traditional Tom Kha Gai uses straw mushrooms, but cremini or button mushrooms work well as substitutes. Oyster mushrooms also add a nice texture and mild flavor to the soup.

→ How do I make this vegetarian?

Replace chicken with firm tofu, use vegetable broth instead of chicken broth, and substitute soy sauce or tamari for fish sauce. The result will be equally flavorful and satisfying.

→ Can I make Tom Kha Gai ahead of time?

Yes, this soup can be prepared up to 2 days in advance. Store it in an airtight container in the refrigerator. Reheat gently over low heat, being careful not to boil the coconut milk, which can cause it to separate.

→ Why shouldn't I let the soup boil vigorously?

Boiling coconut milk too vigorously can cause it to separate and become grainy, affecting both the texture and appearance of the soup. A gentle simmer preserves the creamy consistency.

→ Where can I find makrut lime leaves?

Makrut lime leaves are available fresh or frozen at most Asian grocery stores, particularly those specializing in Southeast Asian ingredients. They can also be purchased dried online, though fresh or frozen are preferred for optimal flavor.
