Step-by-Step Instructions
- Prepare the Fish:
- Pat the fish fillets completely dry with a paper towel and sprinkle both sides with salt and black pepper This ensures they will absorb flavor and cook up tender Set aside on a clean plate while prepping other ingredients
- Build the Aromatic Base:
- In a large heavy bottomed pot heat olive oil over medium heat Add the diced onion and sauté for about three to four minutes until it softens and begins to turn translucent Stir in the minced garlic grated ginger and red curry paste Cook everything for one full minute making sure the curry paste becomes aromatic but does not burn
- Combine Soup Base Ingredients:
- Pour the coconut milk and your choice of chicken or vegetable broth into the pot Stir several times to mix the curry paste thoroughly with the liquid Raise the heat slightly until the base just starts to simmer
- Cook the Fish:
- Gently place the seasoned fish fillets into the simmering soup base Cover the pot partially to keep steam in but avoid a full boil Let the fish poach for roughly eight to ten minutes When the fillets turn opaque and flake apart with a fork they are perfectly done Take care not to overcook as the fish can become tough
- Finish the Soup:
- Stir in the fish sauce and squeeze in fresh lime juice Taste the broth and adjust salt pepper or more lime if you like extra tang This is where you bring the flavors together so do not rush this step
- Serve and Garnish:
- Using a wide ladle carefully serve the soup into bowls Top each serving with generous chopped cilantro Pass lime wedges at the table for each person to add more citrus if desired

I especially love how the coconut milk transforms the broth into something both creamy and light My family always remembers the first time we made this soup on a rainy day everyone gathered to squeeze their own lime wedges and slurp up every drop

Storage Tips
Let leftovers cool and store them in a tightly sealed container in the refrigerator for up to two days If possible keep the cilantro and lime wedges separate until serving Gently reheat on the stove over low heat to maintain the delicate flavor of the fish
Ingredient Substitutions
If you cannot find white fish try shrimp or even cubes of extra firm tofu for a vegetarian option Swap out red curry paste for green for a milder profile and use light coconut milk for a lighter texture but expect less richness Fresh dill or Thai basil also taste wonderful in place of cilantro
Serving Suggestions
Enjoy the soup as it is or serve with jasmine rice or a crusty bread to soak up the broth Pair with a simple side salad of cucumber and fresh herbs for a bright meal Consider a sprinkling of thinly sliced red chili if you like a little spice
Cultural Context
Inspired by Southeast Asian coconut soups this recipe captures that blend of sweet creamy citrusy and savory tones you often find in Thai cooking The lime and cilantro bring a fresh twist while keeping the preparation simple and approachable for home kitchens
