Step 1: Prepare the Aromatics

  1. Lemongrass: Remove the tough outer layers of the lemongrass stalk. Cut it into 3-inch pieces and gently smash the stalk with the back of a knife. This releases its flavor.
  2. Galangal: Slice the fresh galangal into thin rounds. If you can’t find galangal, substitute with ginger, but note that the flavor will be slightly different.
  3. Kaffir Lime Leaves: Tear the leaves into pieces to release their aromatic oils. If lime leaves are unavailable, use the zest of one lime as a substitute.

Step 2: Simmer the Broth

  1. In a large pot, combine chicken broth (or water) with the prepared lemongrass, galangal, and kaffir lime leaves.
  2. Bring the mixture to a gentle boil over medium heat. Let it simmer for 5-7 minutes to infuse the broth with the fragrant aromatics.
  3. Add the Thai bird’s eye chilies for heat, if desired.

Tip: Don’t skip this simmering step—it’s essential for extracting the complex, aromatic flavors of the herbs.

Step 3: Add Coconut Milk and Chicken

  1. Pour the coconut milk into the pot, stirring gently to combine it with the broth. Lower the heat to a gentle simmer—avoid boiling the coconut milk, as it may curdle.
  2. Add the thinly sliced chicken and cook for about 5-6 minutes, or until the chicken is cooked through.
  3. Stir in the sliced mushrooms and let them simmer for another 2-3 minutes until tender.

Step 4: Season the Soup

  1. Add the following seasonings to the soup:
    • Fish sauce for saltiness
    • Palm sugar for sweetness
    • Fresh lime juice for tanginess
  2. Stir well and taste. Adjust the flavor balance as needed:
    • Add more lime juice if you want it tangier.
    • Add a little more fish sauce for saltiness.
    • Add more sugar for sweetness.

Tip: Balance is key—Tom Kha Gai should be tangy, creamy, and lightly salty with a hint of sweetness.

Step 5: Serve and Garnish

  1. Remove the lemongrass stalks, galangal slices, and kaffir lime leaves from the pot. These are not meant to be eaten, as they remain tough even after cooking.
  2. Ladle the hot soup into serving bowls.
  3. Garnish with fresh cilantro leaves, sliced green onions, and a wedge of lime for an extra burst of freshness.

Tips for Perfect Tom Kha Gai Soup

  1. Don’t Boil Coconut Milk: Simmer gently to keep the soup creamy and smooth. Boiling can cause the coconut milk to curdle.
  2. Adjust the Spice: Thai bird’s eye chilies pack a punch! Start with one chili and add more if you like extra heat. For mild soup, omit the chilies entirely.
  3. Fresh Ingredients Matter: Fresh lemongrass, galangal, and kaffir lime leaves create authentic flavor. If you can’t find them, substitutes like ginger and lime zest work well.
  4. Protein Options: Substitute chicken with shrimp, tofu, or thinly sliced pork for variety.
  5. Vegan/Vegetarian: Use vegetable broth, skip fish sauce, and replace chicken with tofu or additional mushrooms. Add soy sauce for a salty alternative.

What to Serve with Tom Kha Gai Soup

This creamy soup is hearty enough to enjoy on its own, but it pairs beautifully with:

  • Steamed Jasmine Rice: To soak up the delicious broth.
  • Spring Rolls: Light and crispy Thai or Vietnamese-style spring rolls.
  • Pad Thai or Thai Fried Rice: For a full Thai-inspired meal.
  • Fresh Mango Sticky Rice: A sweet Thai dessert to finish off your meal.

Storage and Reheating

  • To Store: Let the soup cool completely and store it in an airtight container in the refrigerator for up to 3 days.
  • To Reheat: Heat the soup gently on the stovetop over low heat, stirring occasionally. Avoid boiling to prevent curdling.
  • Freezing: While you can freeze the soup, the coconut milk may separate slightly upon thawing. Stir well while reheating for the best texture.
