What Is Coconut Fish Soup?
A coconut fish soup is a light yet creamy soup made by infusing coconut milk with natural seasonings like ginger, onion, and other aromatics to give it depth and more flavor. Then, add fish to the hot soup to poach it till tender.
Different versions are found throughout Southeast Asia, where coconut milk, fresh seafood, ginger, garlic, herbs, and citrus are commonly used to create flavorful, comforting soups.
Lime is one of those citruses that balance with acid and zest, making coconut lime fish soup… one of the best!
This version keeps things simple with everyday ingredients while delivering real, fresh flavor.
The coconut milk creates a silky broth, ginger and garlic add warmth, tomatoes bring a subtle sweetness and umami, and fresh lime juice balances everything with a bright finish.
The lime really elevates the entire dish (don’t skip it).
The result is a restaurant-quality coconut fish soup recipe that’s surprisingly easy enough for beginner cooks.

- ¾ tablespoon avocado oil
- 1 shallot, thinly sliced
- 1 tablespoon fresh ginger, julienned or minced
- 2 garlic cloves, minced
- 1 tomato, chopped
- 1 (14-ounce) can regular coconut milk (for the creamiest broth)
or use lite coconut milk for fewer calories - ½ cup water
- 1 teaspoon fish sauce – or substitute salt if you don’t have fish sauce
- 8 ounces white fish fillets
- ½ cup greens – baby spinach, bok choy, or mustard greens
- Fresh cilantro – garnish
- 1 whole lime, cut into wedges for squeezing
- Chili Oil – optional garnish
Excellent fish choices include:

Equipment
- Medium soup pot or Dutch oven with a Lid
- Cutting board and Chef’s knife
- Wooden spoon or spatula
- Ladle
Instructions
This easy coconut fish soup recipe comes together in just a few simple steps.
- Heat the avocado oil over medium heat. Add the shallot, garlic, ginger, and chopped tomato.
- Sauté for about 4–5 minutes, stirring occasionally, until the shallots soften and the tomatoes begin to break down. This allows the aromatics to release their incredible flavor into the soup.
- Pour in the coconut milk and water. Then, add the fish sauce (or salt).
- Reduce the heat to a low simmer and cook for 10 minutes with a lid on the pot, allowing the coconut milk to absorb all of the flavors from the ginger, garlic, shallots, and tomatoes.
- Carefully add the fish fillets. Gently poach for about 7 minutes, or until the fish is opaque and flakes easily with a fork. (Avoid boiling the soup, as gentle poaching keeps the fish tender and moist.)
- Add the spinach, bok choy, or mustard greens. Cook just until the greens wilt, about 1 minute.
- Ladle the soup into bowls. Top with plenty of fresh cilantro, generous squeezes of fresh lime juice. (Add a drizzle of chili oil if desired). Enjoy and Serve immediately.

Best Tips

- Use fresh ingredients, no powders or frozen. This ensures the best flavor!
- Simmer the broth gently and with enough time (at least ten minutes) to allow the aromatics to fully infuse the coconut milk.
- Never boil the fish. Gently poach it over low heat for tender, flaky results.
- Add the greens at the very end so they stay bright and fresh.
- Squeeze plenty of fresh lime juice over each bowl just before serving – it truly brings the coconut lime fish soup to life.
- Taste the broth before serving and adjust with a little more fish sauce, salt, or lime juice if needed.
