Ingredients You’ll Need
To craft this Tom Kha Gai Soup Recipe, you’ll want to gather some simple but essential ingredients that each add their own unique character—whether it’s the vibrant aroma, creamy texture, or rich depth of flavor.
- Vegetable oil: This is the base for sautéing aromatics, helping to release their flavors early on.

- Lemongrass stalks: Cut and smashed to release their citrusy, fragrant oils.

- Coconut milk: The star of creamy richness, making this soup ultra-satisfying.
- Chicken broth (or water): The flavorful liquid base that carries all the ingredients together.
- Fish sauce: A salty, umami punch that elevates the soup’s depth tremendously.

How to Make Tom Kha Gai Soup Recipe
Step 1: Prepare the Aromatics
Start by heating the vegetable oil in a large pot over medium heat. Toss in the sliced onion, lemongrass pieces, torn kaffir lime leaves, and smashed bird’s eye chilies. Sautéing these ingredients unlocks their vibrant aromas and lays the fragrant foundation for an unforgettable soup. You’ll know you’re on the right track when your kitchen fills with the unmistakable scent of fresh citrus mingled with a touch of spicy warmth.
Step 2: Add the Chicken
Next, add the thinly sliced chicken to the pot and cook it gently for about five minutes. The goal here is to get the chicken just cooked through while allowing it to soak up the aromatic flavors. Stir occasionally to ensure the chicken cooks evenly and doesn’t stick, turning tender and juicy, ready to shine as the star protein of the dish.
Step 3: Simmer the Broth
Pour in the creamy coconut milk together with the chicken broth (or water, if you prefer a lighter version). Stir in the fish sauce and sugar to bring balance between savory and sweet. Bring the entire concoction to a gentle simmer over medium heat. During this 10 to 15-minute simmer, the flavors will meld beautifully, coaxing out a luxurious, silky broth that’s the soul of this Tom Kha Gai Soup Recipe.
Step 4: Add the Vegetables
Now it’s time to add the mushrooms and optional tomato quarters to the pot. The mushrooms tenderize while soaking up all the savory goodness, adding delightful texture. If using tomatoes, they lend a mellow acidity and vibrant color, brightening the soup’s presentation. Let everything simmer together for another 5 to 7 minutes until the vegetables are perfectly tender.
Step 5: Adjust the Seasoning
Remove the pot from heat and stir in fresh lime juice to finish the broth with a lively zing. Taste your creation and personalize it by adding more fish sauce if you want it saltier, a pinch more sugar for sweetness, or additional lime juice to amp up the acidity. This step is your chance to make this Tom Kha Gai Soup Recipe truly your own, finding the perfect balance of flavors for your palate.
Step 6: Serve
Ladle the steaming soup into bowls but be sure to discard the lemongrass stalks and kaffir lime leaves—they’ve done their job but aren’t meant to be eaten. Garnish with freshly chopped cilantro and Thai basil leaves if you have them on hand. For an extra touch, drizzle chili oil or sprinkle chili flakes for heat lovers. Serve immediately and savor every fragrant, creamy spoonful.
How to Serve Tom Kha Gai Soup Recipe
Garnishes
Fresh herbs like cilantro and Thai basil not only add pops of green color but also contribute fresh aromatic layers that complement the rich broth gorgeously. A splash of chili oil or sprinkle of chili flakes can personalize your soup’s spice level and add a lovely visual contrast. Don’t underestimate the power of these final touches—they transform a great soup into a memorable experience.
Side Dishes
Tom Kha Gai Soup stands beautifully on its own but pairs exceptionally well with fragrant jasmine rice to round out the meal. If you want to venture further, consider serving it alongside lightly stir-fried vegetables or crisp spring rolls for texture variety. The soup’s creamy, tangy richness balances perfectly with these complementary textures and flavors.
Creative Ways to Present
For a dinner party or special treat, serve this soup in mini coconut bowls or rustic ceramic mugs for a charming, authentic touch. Garnish with edible flowers or fresh lime wedges on the side to impress guests visually while enhancing flavor. You can also add a drizzle of coconut cream on top to intensify the creaminess and create gorgeous swirls—always a crowd-pleaser!
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftover Tom Kha Gai Soup Recipe (though it’s rare!), store it in an airtight container in the refrigerator. It will keep well for up to 3 days. Flavors often deepen overnight, making the soup even more delicious the next day.
Freezing
Freezing Tom Kha Gai Soup is possible but with a small caveat: the texture of the coconut milk can change slightly after freezing. To mitigate this, cool the soup completely before freezing it in a sealed container. Frozen soup should be consumed within 1 to 2 months for best quality.
Reheating
Reheat gently on the stovetop over medium-low heat, stirring occasionally to prevent the coconut milk from separating. Avoid boiling vigorously, which can cause texture and flavor degradation. A light stir combined with a gentle simmer will restore your soup to near-fresh taste and texture.
FAQs
Can I use chicken thighs instead of breasts?
Absolutely! Chicken thighs are actually preferred by many for their juicier, more tender texture, and they absorb the soup’s flavors beautifully. Just slice them thinly as you would with breasts.
What can I substitute for kaffir lime leaves?
If you can’t find kaffir lime leaves, lime zest is a good substitute to add the citrus fragrance, although it’s not as intense. You could also try a small amount of lime juice, but add it carefully so as not to overpower the broth.
How spicy is this soup traditionally?
The traditional Tom Kha Gai Soup Recipe has a gentle heat from bird’s eye chilies, which adds warmth without overwhelming the other flavors. You can easily adjust the heat to your liking by using fewer chilies or adding more chili oil at the end.
Is this soup gluten free?
Yes, this recipe is naturally gluten free, especially if you use gluten-free fish sauce and chicken broth. It’s a fantastic choice if you’re mindful of gluten in your diet.
Can I make this soup vegetarian or vegan?
Definitely! Swap chicken broth for vegetable broth, skip the chicken, and add tofu or extra mushrooms for protein. Also, replace fish sauce with soy sauce or tamari to keep it vegan-friendly without losing umami depth.
