Coconut Lime Fish Soup with tender white fish, creamy coconut milk, fresh lime, red bell pepper, and cilantro
This Coconut Lime Fish Soup combines tender white fish, creamy coconut milk, fresh lime, ginger, garlic, and colorful red bell pepper in a bright, flavorful broth.
It’s an easy one-pot seafood dinner that comes together in about 30 minutes and delivers a delicious balance of creamy, savory, citrusy, and slightly sweet flavors.
The recipe is inspired by the combination of coconut milk, lime, ginger, herbs, and fish sauce often found in Southeast Asian-style cooking, while keeping the ingredient list simple enough for a busy weeknight.
Serve it on its own for a lighter dinner or spoon it over jasmine rice when you want something more filling.

There’s a lot to love about this easy seafood soup.
Ready in about 30 minutes: Most of the cooking time is spent building the coconut broth before the fish is added at the end.
One-pot dinner: Everything cooks in a single pot, which keeps cleanup simple.
Bright, creamy flavor: Coconut milk creates a rich broth while fresh lime keeps the soup from feeling too heavy.
Flexible fish options: Cod, tilapia, haddock, pollock, or another firm white fish can work.
Easy to customize: Add vegetables, chili, spinach, shrimp, or rice depending on what you have available.
You’ll need:
A firm, mild white fish works best for this coconut fish soup.
Good choices include:
Cut the fillets into similar-sized pieces so they cook at approximately the same rate.
Use canned coconut milk rather than refrigerated coconut beverages.
Full-fat coconut milk creates the richest broth, while light coconut milk can be used if you prefer a thinner soup.
Fresh lime juice is important because it provides the bright citrus flavor that balances the coconut milk.
Bottled lime juice can work in a pinch, but fresh is preferable here.
Fish sauce adds savory depth.
Because brands vary significantly in saltiness, start with the amount listed and taste the soup before adding additional salt.
Fresh ginger works particularly well with coconut milk and lime.
If possible, use freshly grated ginger instead of ground ginger.
Cut the fish into bite-sized pieces.
Pat the pieces dry with paper towels and keep them refrigerated while you prepare the broth.
Avoid rinsing raw fish under running water.
Heat the olive oil in a large pot over medium heat.
Add the chopped onion and cook for approximately 4–5 minutes, stirring occasionally, until softened.
Add the minced garlic and grated ginger.
Cook for approximately 30–60 seconds, stirring frequently.
You want the aromatics to become fragrant without allowing the garlic to burn.
Stir in the sliced red bell pepper.
Cook for another 3–4 minutes, until it begins to soften.
Pour in:
Stir well and bring the mixture to a gentle simmer.
There is no need to aggressively boil the soup. A gentle simmer gives you better control once the fish is added.
Stir in:
Taste the broth before adding extra salt because fish sauce can already contribute substantial saltiness.
Gently add the pieces of fish to the simmering broth.
Cook for approximately 5–7 minutes, depending on the size and thickness of the pieces.
Avoid stirring aggressively after adding the fish because cooked fish can break apart easily.
Fish should reach a safe internal temperature of 145°F in the thickest portion.
The flesh should also appear opaque and separate easily.
Remove the pot from the heat.
Stir in the chopped cilantro.
Taste and add additional lime juice, fish sauce, salt, or pepper if needed.
Ladle the soup into bowls and garnish with:
Serve immediately.
Fish cooks quickly, so timing matters.
Build your entire coconut broth first.
Add the raw fish only when the soup is nearly finished.
You don’t need a hard boil.
A gentle simmer gives the fish time to cook without breaking apart as easily.
Uniform pieces cook more evenly.
Once the fish reaches 145°F, remove the soup from the heat.
Overcooking can make lean white fish dry or tough.
Several types of white fish work well in this recipe.
Cod is one of the easiest choices because its mild flavor works well with coconut and lime.
For another cod recipe, try YumAndRun’s Crispy Fried Cod Fish Recipe.
Rockfish also works well because of its relatively mild flavor.
You can see another preparation method in this Easy Rockfish Recipe.
Tilapia cooks quickly and has a mild flavor, though thinner fillets may require less cooking time.
Haddock is another good choice for a creamy fish soup.
You can even replace the white fish with shrimp.
Because shrimp cooks quickly, add it near the end and cook only until opaque and properly cooked through.
Once you’ve made the basic version, there are several easy ways to change it.
Add:
Start conservatively and add more heat to taste.
Stir fresh spinach into the soup during the final minute or two.
It wilts very quickly.
Replace the fish with peeled, deveined shrimp.
Add the shrimp near the end so they don’t overcook.
Add a spoonful of red curry paste when cooking the garlic and ginger.
This creates a deeper, more aromatic broth.
You can add:
Dense vegetables should be added earlier than quick-cooking vegetables.
This soup is flavorful enough to serve on its own, but a few simple sides can turn it into a more substantial dinner.
Rice is probably my first recommendation.
Spoon the soup over jasmine rice or serve the rice alongside it.
Bread is useful for soaking up the coconut-lime broth.
A crisp cucumber salad adds freshness and texture.
Try broccoli, green beans, or snap peas.
A lightly dressed salad helps keep the overall meal fresh.

The broth is particularly good for making ahead.
Prepare the coconut broth without the fish and refrigerate it.
When you’re ready to eat, reheat the broth until simmering and add the fish during the final few minutes.
That method gives you better fish texture than repeatedly reheating already-cooked seafood.
Transfer leftover soup to an airtight container and refrigerate it promptly.
Use refrigerated cooked seafood leftovers within approximately 3–4 days.
I would avoid saying the soup is necessarily “better the next day.” The broth may develop more flavor, but cooked fish generally has its best texture when freshly prepared.
Reheat leftovers gently in a saucepan over medium-low heat.
Stir carefully so the fish pieces don’t break apart.
Heat until the soup is thoroughly hot.
Avoid repeatedly bringing the soup to a hard boil because prolonged cooking can make the fish dry and cause some separation in the coconut broth.
It has a creamy coconut base balanced by fresh lime, ginger, garlic, savory fish sauce, and tender white fish.
The result is creamy but bright rather than overly heavy.
Firm white fish such as cod, haddock, rockfish, pollock, or tilapia works well.
Yes.
Thaw frozen fish safely before using it, then pat it dry and cut it into pieces.
Bite-sized pieces often cook within approximately 5–7 minutes, depending on their size and thickness.
The most reliable indicator is an internal temperature of 145°F.
Yes.
Shrimp is an excellent alternative and generally cooks faster than chunks of white fish.
Absolutely.
Add chili flakes, sliced chili peppers, or chili paste to taste.
Yes, although the broth will be less rich and creamy than when using full-fat coconut milk.
Coconut milk can separate somewhat during prolonged or aggressive boiling, but that doesn’t necessarily mean the soup is ruined.
For the smoothest texture, keep the soup at a gentle simmer.
You can, but I prefer serving cooked rice separately.
That prevents the rice from absorbing too much broth during storage.
