Instructions
Step 1: Prepare the Base
Heat the oil in a large soup pot over medium heat. Add the onion and sauté for 3–4 minutes until soft and translucent.
Add garlic and ginger, cooking for another 1 minute until fragrant.
Step 2: Add Vegetables
Stir in the bell pepper, carrots, mushrooms, and chili if using. Cook for 4–5 minutes until slightly tender.
Step 3: Build the Broth
Pour in the fish stock and coconut milk. Stir well.
Add fish sauce, soy sauce, curry paste, and lemongrass if using. Bring the soup to a gentle simmer.
Step 4: Cook the Fish
Add the fish chunks carefully into the simmering soup.
Cook for 6–8 minutes, or until the fish becomes opaque and flakes easily.
Step 5: Finish the Soup
Remove lemongrass if used.
Stir in lime juice, lime zest, and spinach. Simmer for 1 minute until the spinach wilts.
Taste and adjust seasoning with salt and pepper.
Step 6: Serve
Ladle the soup into bowls and garnish with cilantro, green onions, chili flakes, and lime wedges.
Serve hot.
Recipe Notes
Use firm white fish so the pieces hold their shape during cooking.
Fresh lime juice gives the best flavor compared to bottled juice.
Avoid boiling the soup after adding fish to prevent overcooking.
Coconut milk may naturally separate slightly; stir gently before serving.
The soup tastes even better after resting for 10–15 minutes.
Tips for Best Results
1. Choose Fresh Fish
Fresh fish gives the soup a cleaner and sweeter flavor. Look for fish with a mild smell and firm texture.
2. Control Spice Level
For mild soup, skip the chili paste. For extra heat, add sliced Thai chilies.
3. Add Herbs at the End
Fresh herbs lose flavor if cooked too long. Always add cilantro near serving time.
4. Make It Heartier
Add cooked rice noodles or jasmine rice for a more filling meal.
5. Balance the Flavor
The perfect soup balances salty, creamy, sour, and spicy elements. Adjust lime juice and fish sauce gradually.
