Ingredients You’ll Need
This Thai-inspired coconut chicken soup is built on bold aromatics, creamy coconut milk, and deeply nourishing flavors. Here’s a breakdown of the core ingredients and a few simple swaps to make it work with what you have on hand.
Broth Base & Aromatics
- 4 cups chicken stock – adds body and depth
- 2–3 tablespoons fish sauce – brings umami and saltiness
- 1–2 stalks lemongrass – score lengthwise to release flavor
- 12 slices galangal – fresh or frozen; can sub with ginger if needed
- 6–8 makrut lime leaves – or zest of 1 lime
- 1–2 Thai chilies (optional) – adds heat; omit for a milder soup
- 2 tablespoons coconut sugar – balances acidity and spice
Veggies & Protein
- 12 oz mushrooms – oyster, shiitake, or cremini, torn into pieces
- 1 medium sweet onion – diced for natural sweetness
- 1 lb rotisserie chicken – shredded for convenience and flavor
Coconut Finish
- 1 can (14 oz) coconut milk – full-fat for creaminess
- 3 tablespoons lime juice – added at the end for brightness
- ½ cup cilantro – roughly chopped for a fresh finish
Optional Garnishes
- Sambal chili paste
- Chili crunch
- Lime wedges
- Sliced green onions
Substitutions & Notes:
- No galangal? Use fresh ginger—start with 4–5 thin slices
- No makrut lime leaves? Lime zest will still give you that signature citrus punch
- Swap rotisserie chicken for tofu to make it vegetarian
- Use vegetable broth instead of chicken stock for a plant-based version
Step-by-Step: How to Make Thai Coconut Chicken Soup
This soup might taste like it simmered all day, but the method is surprisingly simple. You’ll build a rich, aromatic broth, infuse it with bold Thai flavors, then finish with creamy coconut milk and bright lime juice.
Here’s exactly how to make it:
1. Build the base
Add the chicken stock, fish sauce, lemongrass, galangal (or ginger), lime leaves, Thai chilies (if using), and coconut sugar to a large pot. Bring to a simmer over medium heat and let everything infuse for about 15–20 minutes.
This step is where the broth gets its depth—don’t rush it. You want the aromatics to fully steep before moving on.
2. Add the vegetables
Toss in the torn mushrooms and diced onion. Simmer for another 10 minutes, until the mushrooms are tender and the onion has softened slightly.
3. Add the chicken
Stir in the shredded rotisserie chicken and reduce the heat to low. Let everything warm through for 5–7 minutes.
4. Stir in the coconut milk
Pour in the full can of coconut milk and stir to combine. Let it gently heat through—do not boil, or the milk may separate. You’re looking for a silky, creamy texture here.
5. Finish with lime juice and cilantro
Turn off the heat. Stir in the lime juice and chopped cilantro. Taste and adjust—add more fish sauce for salt, more lime for acidity, or a splash of coconut sugar if you want it slightly sweeter.
