How to Make It
- Prep the aromatics: Trim lemongrass, remove the tough outer layer, and smash the stalks with the back of a knife.
Slice galangal or ginger. Tear the kaffir lime leaves. Slice the chiles and shallots.
- Build the base: In a medium pot, warm a little oil over medium heat.
Add shallots and a pinch of salt. Cook 2–3 minutes until fragrant. Stir in curry paste and sliced chiles, and cook 30–60 seconds to bloom the flavors.
- Add broth and aromatics: Pour in the broth.
Add lemongrass, galangal, and kaffir lime leaves. Simmer gently for 10 minutes to infuse.
- Stir in coconut milk: Reduce heat to medium-low. Add coconut milk and mushrooms.
Simmer another 5 minutes. Keep it just below a boil to prevent curdling.
- Cook the protein: Add thinly sliced chicken or tofu. If using shrimp, add it later since it cooks fast.
Simmer until the protein is just cooked through—about 3–5 minutes for chicken, 2–3 minutes for shrimp, 4–5 minutes for tofu to warm through.
- Season: Add fish sauce, sugar, and lime juice. Taste and adjust. You’re aiming for a balance of salty, sour, spicy, and creamy.

Keeping It Fresh
- Storage: Cool completely and refrigerate in a sealed container for up to 3 days. The flavors deepen by day two.
- Reheating: Warm gently over low heat until hot, without boiling. Add a splash of broth or water if it thickens.
- Freezing: Freeze the broth without herbs and tomatoes for up to 2 months.
Add fresh herbs and lime after reheating to keep flavors bright.
- Make-ahead tips: Keep aromatics and proteins prepped separately. You can simmer the infused broth ahead and add coconut milk and protein just before serving.
Why This is Good for You
- Protein-rich: Chicken, shrimp, or tofu make it satisfying without feeling heavy.
- Healthy fats: Coconut milk provides medium-chain fats that help with satiety and flavor.
- Anti-inflammatory aromatics: Ginger/galangal, lemongrass, and chilies bring antioxidants and a soothing effect.
- Lower-carb option: Enjoy it as is for a light, low-carb meal, or add rice if you want more energy.
- Hydrating and soothing: Warm broth supports hydration and feels comforting on cold days or when you’re under the weather.
What Not to Do
- Don’t boil hard after adding coconut milk: Vigorous boiling can cause separation and a grainy texture.
- Don’t skip the acid: Lime juice is essential. Without it, the soup tastes flat.
- Don’t overcook the protein: Thin slices cook fast.
Pull the pot off heat as soon as they’re done.
- Don’t forget to remove the aromatics: Lemongrass, galangal, and lime leaves are for flavoring, not chewing.
- Don’t rely on salt alone: Use fish sauce or soy for depth. Plain salt misses the umami note.
Recipe Variations
- Vegetarian/Vegan: Use vegetable broth and soy sauce or tamari. Add tofu and extra mushrooms.
A splash of soy and a touch of miso add depth.
- Tom Yum–inspired: Increase lime juice, add more chilies, and skip the curry paste. Stir in a spoon of chili paste in oil for heat and aroma.
- Extra creamy: Use 1.5 cans of coconut milk and reduce the broth slightly for a richer soup.
- Noodle bowl: Add soaked rice noodles during the last 2–3 minutes, or ladle the soup over cooked noodles.
- Seafood mix: Combine shrimp, thinly sliced fish, and a few mussels. Add them in stages so nothing overcooks.
- More veggies: Add baby spinach, bok choy, or snow peas in the last minute.
Keep them crisp-tender.
- Peanut or cashew twist: Stir in 1 tablespoon peanut or cashew butter for a nutty undertone. Balance with extra lime.
FAQ
Can I make this without lemongrass and kaffir lime leaves?
Yes. Use a mix of lime zest, extra lime juice, and a bit more ginger to mimic the brightness.
It won’t be exactly the same, but it will still be delicious and aromatic.
How spicy is this soup?
It’s as spicy as you make it. Start with one chile and 1 tablespoon curry paste, then add more to taste. You can also remove the chile seeds to reduce heat.
What protein works best?
Thinly sliced chicken breast or thighs are classic, but shrimp cooks quickly and stays juicy.
For a plant-based bowl, firm tofu or tempeh works well.
Can I use light coconut milk?
You can, but the soup will be thinner and less silky. If using light coconut milk, simmer a little longer to concentrate, and avoid boiling.
What should I serve with it?
Steamed jasmine rice, rice noodles, or a simple cucumber salad pairs well. Lime wedges and fresh herbs on the side brighten each bowl.
Why did my soup split?
Coconut milk can separate if boiled hard or if the heat is too high for too long.
Keep it at a gentle simmer and add the coconut milk after the broth is infused.
Can I double the recipe?
Absolutely. Use a larger pot and keep the simmer gentle. Taste and adjust seasoning at the end, especially lime and fish sauce.
Is fish sauce necessary?
It adds deep umami and saltiness.
If you don’t eat fish, use soy or tamari and consider a small spoon of white miso for extra depth.
Final Thoughts
