Velvety Thai Coconut Chicken Soup (Tom Kha Gai)

Save

There’s something undeniably magical about a bowl of Thai Coconut Chicken Soup — it’s soothing yet vibrant, creamy yet refreshing. Each spoonful feels like a trip through Thailand’s bustling night markets, where coconut milk, lemongrass, and lime mingle in perfect harmony. This is comfort food with a little mystery — warm, aromatic, and beautifully balanced between spicy, tangy, and sweet.

When I first tried Tom Kha Gai at a small Thai restaurant, it completely reset how I thought soup could taste. The depth from the coconut milk, the zing of fresh lime, and the gentle heat of chili — it was like my taste buds woke up. This recipe captures all that flavor in a way that’s approachable, homey, and just right for slow evenings or cozy weekends.

Cultural Background

Tom Kha Gai (ต้มข่าไก่) is a beloved Thai soup whose name literally means “boiled galangal chicken.” Originating in Central Thailand, it’s a classic representation of the country’s balance-driven cuisine. The flavors — spicy, sour, salty, and sweet — come together through staples like galangal, lemongrass, kaffir lime leaves, and fish sauce.

Traditionally, it’s served as part of a family-style meal, alongside jasmine rice and other small dishes. The coconut milk gives it that creamy body while keeping it lighter than Western-style cream soups. Over time, it’s become one of Thailand’s most recognized dishes abroad — elegant yet easy to love.

Ingredient Spotlight

• Coconut milk: The creamy heart of the soup that softens the spice and adds richness.
• Galangal: Similar to ginger but with a sharper, more citrusy flavor (essential for true Thai flavor).
• Lemongrass: Adds a bright, lemony aroma that keeps the soup fresh and lively.
• Kaffir lime leaves: Intensify the citrus undertone — a little goes a long way.
• Fish sauce & lime juice: Balance saltiness and tang perfectly.
• Thai chili: Brings the heat and depth that make this dish unmistakably Thai.

Prep Timeline

Prep time: 10 minutes
Cook time: 20 minutes
Total time: 30 minutes
Serves: 4

Ingredients

• 1 tbsp coconut oil
• 1-inch piece galangal (or ginger), sliced
• 2 stalks lemongrass, trimmed and smashed
• 3 kaffir lime leaves (optional but recommended)
• 4 cups chicken broth
• 1 can (14 oz) coconut milk
• 2 chicken breasts, thinly sliced
• 1 cup mushrooms, sliced (shiitake or button)
• 2 tbsp fish sauce
• 1 tbsp lime juice (plus more to taste)
• 1–2 Thai red chilis, sliced (adjust to heat preference)
• 1 tsp brown sugar
• Fresh cilantro and green onions for garnish

Instructions

1. In a large pot, heat coconut oil over medium heat. Add galangal, lemongrass, and lime leaves. Sauté briefly until fragrant (about 1–2 minutes).
2. Pour in chicken broth and bring to a gentle boil. Simmer for 5–7 minutes to infuse the broth.
3. Add coconut milk, chicken slices, and mushrooms. Reduce heat and cook until the chicken is fully cooked (about 10 minutes).
4. Stir in fish sauce, lime juice, sugar, and Thai chili. Taste and adjust balance — more lime for tang, more fish sauce for saltiness, or more chili for spice.
5. Remove the lemongrass and galangal pieces before serving.
6. Garnish with cilantro and green onions. Serve warm with jasmine rice or on its own.

Pro Tips and Troubleshooting

• Don’t boil coconut milk. Keep it at a gentle simmer to prevent curdling.
• No galangal? Use ginger, though the flavor will be milder.
• Balance the taste. Thai cuisine thrives on balance — taste as you go and adjust salt, sour, and spice.
• Leftovers: The soup deepens in flavor overnight — it’s even better the next day.

Variations and Add-Ins

• Shrimp Tom Kha: Replace chicken with shrimp for a seafood twist.
• Vegetable Version: Use tofu, zucchini, carrots, or bell peppers instead of chicken.
• Extra Creamy: Stir in a second can of coconut milk for a richer base.
• Vegan Variation: Substitute chicken broth with vegetable broth, omit fish sauce, and use soy sauce or tamari instead. Add tofu or tempeh for protein.

Serving Ideas

Serve this soup as a starter or a light main dish with jasmine rice, coconut rice, or even rice noodles. It pairs beautifully with Thai spring rolls or a crisp cucumber salad.

Storage and Reheating

• Refrigerate: Store up to 4 days in an airtight container.
• Freeze: Best up to 1 month — reheat gently to avoid splitting the coconut milk.
• Reheat: Warm slowly over low heat and stir occasionally to bring back the creamy consistency.
