Ingredients You’ll Need
This Coconut Lime Fish Soup is all about simple ingredients coming together for maximum flavor. Each one has a role to play, creating a harmony of textures, colors, and layers of taste that make this soup truly unforgettable.
- White fish fillets (such as cod or halibut): Choose a mild, firm fish that holds together in the soup and soaks up the bursting flavors.

- Onion: This aromatic creates a sweet foundation and deepens every spoonful.
- Garlic: Brightens up the broth and teams perfectly with ginger.
- Fresh ginger: Adds a gentle, zingy heat that balances the creamy coconut.
- Fish stock or chicken broth: The flavorful backbone of your soup — choose fish stock for extra seafood richness, or chicken broth for a mellower vibe.
- Coconut milk: The silky, creamy star ingredient that brings subtle sweetness and richness.
- Fish sauce: Just a splash adds deep umami and that classic Southeast Asian edge.
- Soy sauce: Rounds out the saltiness and works hand-in-hand with the fish sauce for complexity.

- Red bell pepper: Brings a gentle sweetness and a splash of cheerful color.
- Mushrooms: For an earthy, tender bite and savory depth.
- Baby spinach: Wilts into the soup, adding nutrition and beautiful green flecks.

- Lime wedges: For serving and extra fresh zing at the table.
How to Make Coconut Lime Fish Soup
Step 1: Build Your Flavor Base
Start by heating the olive oil in a spacious pot over medium heat. Add your diced onion, and let it soften gently — about 5 minutes of slow cooking gives you that lovely sweetness as the backbone of the Coconut Lime Fish Soup. Stir in the garlic and fresh ginger, and cook for another minute just until your kitchen smells absolutely heavenly.
Step 2: Pour In Broth and Coconut Milk
Next, pour in your fish stock (or chicken broth) and bring the mixture up to a gentle boil. It’s amazing how quickly the broth develops depth! Lower the heat and add the coconut milk, fish sauce, soy sauce, lime juice, and lime zest. This dreamy blend will immediately whisk you away with aromas of the tropics.
Step 3: Add Veggies
Now, toss in the thinly sliced red bell pepper and mushrooms. Let them simmer for about 5 minutes, just until they start to soften and lend their sweetness and earthiness to the soup. This step introduces color, crunch, and a hearty character that balances the richness.
Step 4: Simmer the Fish
Very gently add the chunks of white fish, slipping them into the simmering soup with care so they stay whole and silky. Simmer for 5 to 7 minutes — you’ll know they’re ready when the fish pieces turn opaque and flake apart with a spoon.
Step 5: Finish with Greens and Seasoning
Stir in the baby spinach and let it wilt beautifully into the Coconut Lime Fish Soup. Season with salt and pepper, then give everything a gentle taste. Adjust, if needed, because the balance of citrus, cream, and umami is what makes this dish just right.
Step 6: Garnish and Serve
Ladle your steaming soup into bowls, top with a flurry of fresh cilantro, and scatter sliced red chili if you’re craving heat. Serve with extra lime wedges on the side, so everyone can make their bowl as bright as they like. Get ready to dig in!
How to Serve Coconut Lime Fish Soup
Garnishes
Once your Coconut Lime Fish Soup is ready, really make it sing with generous garnishes. A big handful of chopped cilantro adds a fresh punch and gorgeous color. Thin slices of red chili (if you dare) offer beautiful contrast and heat. Extra lime wedges on the side invite everyone to squeeze more zing into their bowl, personalizing the brightness to suit their tastes.
Side Dishes
Pairing is half the fun! Serve your Coconut Lime Fish Soup over gently steamed jasmine rice or a tangle of rice noodles for a heartier meal. A side of crispy spring rolls, a simple cucumber salad, or even a small plate of pickled veggies is all you need to turn soup into a show-stopping dinner feast.
Creative Ways to Present
Don’t just pour your soup into plain bowls — have fun with it! Try serving the Coconut Lime Fish Soup in wide soup plates for a restaurant feel, or use small mugs for a cozy starter. If you’re feeling tropical, consider hollowed-out coconut shells! Add a swirl of coconut milk or a sprinkle of toasted coconut flakes on top for a playful finish.
Make Ahead and Storage
Storing Leftovers
If you have leftover Coconut Lime Fish Soup, let it cool completely and then store it in an airtight container in the fridge. It will stay fresh for up to 2 days. Just be aware that the fish is at its best texture when freshly cooked, but leftovers still taste fantastic.
Freezing
You can absolutely freeze this soup! Simply cool the Coconut Lime Fish Soup and transfer it to freezer-safe containers, leaving a little space at the top for expansion. Freeze for up to one month. For best results, freeze before adding the spinach and cilantro — stir those in after reheating to preserve their color and texture.
Reheating
To reheat, place the soup in a saucepan and warm it gently over low to medium heat, stirring occasionally. Avoid boiling, as this can overcook the fish and make the coconut milk separate. Once hot, add any fresh herbs or greens, and serve immediately.
FAQs
Can I use a different type Soup
Absolutely! Any mild, firm white fish will work beautifully in Coconut Lime Fish Soup. Try tilapia, pollock, or even sea bass. Just avoid oily fish like salmon, as they can overpower the delicate flavors.
Is there a vegan version of this soup?
Definitely! Replace fish with cubes of tofu or tempeh, use vegetable broth instead of fish stock, and omit the fish sauce (or use a plant-based alternative). The rest of the flavors still shine just as brightly.
How spicy is Coconut Lime Fish Soup?
As written, the soup is gently warming from the ginger with only a suggestion of heat from optional red chili. For more fire, feel free to add more chili or a spoonful of Thai red curry paste.
Can I make this soup ahead?
You can prep most of it in advance! Cook up to the point of adding the fish, refrigerate, then gently reheat and add the fish and greens just before serving for the freshest results.
What can I substitute for coconut milk?
Coconut milk is what makes this soup special, but you could try unsweetened cashew or almond milk for a lighter, non-coconut version. The flavor and creaminess will be different, but still lovely.
Final Thoughts
If you’re looking to brighten up mealtime, this Coconut Lime Fish Soup is your ticket to a bowl full of color, flavor, and comfort. Each spoonful is a little celebration of zest and creaminess, perfect for sharing with friends or savoring solo.
