Belizean Fish Soup Recipe: Citrusy Coconut and Herb Infusion

This Belizean fish soup recipe brings the vibrant flavors of the Caribbean coast to your kitchen with its bright citrus and creamy coconut infusion. 🌊 The secret lies in balancing tart lime juice with sweet coconut milk, creating a broth that's both refreshing and deeply satisfying.

I developed this version after years of perfecting the technique for achieving that signature Belizean harmony—where Scotch bonnet peppers add just enough heat without overpowering the delicate fish.

The foundation of this soup is a rich tomato-coconut base that simmers until deeply flavorful, while fresh herbs like cilantro and thyme add layers of aromatic complexity.

What sets this recipe apart is the careful preparation of the fish—whether you use snapper, kingfish, or another firm white fish—each piece cooks just until tender, absorbing the citrusy broth without falling apart.

The addition of callaloo or cassava brings hearty texture, while plantains add natural sweetness that balances the dish perfectly.

By the time you serve this soup, you'll have a steaming bowl of golden broth filled with tender fish, vibrant vegetables, and a garnish of fresh herbs that makes every spoonful taste like a Belizean seaside feast.

The aroma alone will transport you to coastal villages, where this dish is a staple for gatherings and celebrations. This recipe delivers restaurant-quality results with simple techniques that any home cook can master.

The beauty of Belizean fish soup lies in its versatility—it works equally well as a light lunch or a hearty dinner, and the flavors only deepen when reheated.

Whether you're serving it to guests or treating yourself to a taste of the Caribbean, this recipe captures the essence of Belizean coastal cuisine in every bowl. Let's create this flavorful masterpiece together.

Ingredients for belizean fish soup

Fresh seafood, citrusy coconut, and aromatic herbs—this Belizean fish soup brings Caribbean flavors to your kitchen.

The fish is the star, so pick firm white fish like snapper or kingfish—they hold up best in the broth. If you can't find Scotch bonnet peppers, Habanero at half the amount works, but trust me on the Scotch bonnet for that authentic Belizean kick. Coconut milk matters too—full-fat gives the best creaminess. I grab mine from Trader Joe's or Costco for the best quality. Fresh lime juice is non-negotiable here—bottled won't cut it. For tomatoes, Roma or vine tomatoes have the best flavor, but any medium tomato works in a pinch. Callaloo is the traditional choice, but frozen cassava leaves are a solid substitute if you can't find it.

No fresh thyme? Dried thyme at one-third the amount gets you close, but fresh is ideal. The plantains should be ripe but firm—think slightly soft to the touch. If you can't find ripe plantains, green bananas work too, but they'll be starchy rather than sweet. For the bouillon cube, Knorr Vegetable Bouillon is my go-to, but any vegetable-based cube will do. The olive oil is just for sautéing, so don't skimp—extra-virgin adds depth. If you're short on time, frozen callaloo or cassava is fine, just thaw and drain it first. The key is balancing the tartness of the lime with the sweetness of the coconut and plantains—don't be afraid to adjust the lime juice to taste.

This soup tastes even better the next day, so make a double batch if you can. Store it in an airtight container in the fridge for up to 3 days. The flavors meld beautifully overnight, and it reheats like a dream. If you have leftovers, freeze portions for up to 3 months. I always make extra because it disappears fast—perfect for meal prep. The broth keeps well too, so you can freeze it separately and add fresh fish later. Garnish with extra cilantro and lime wedges right before serving to keep everything vibrant.

Step-by-step instructions for Belizean fish soup

Here's how to create this vibrant, citrusy soup that balances creamy coconut with bold Caribbean flavors.

Heat the 2 tablespoons olive oil in a large pot over medium heat. Add the diced onion and cook for 3-4 minutes until soft and translucent. This is your flavor foundation—don't rush it or the soup will taste raw.

Add the 4 minced garlic cloves and 1 tablespoon chopped fresh thyme, stirring for 30 seconds until fragrant. You'll smell that fresh, herby aroma—this is when the magic starts. Immediately add the 2 medium diced tomatoes and cook for another 3 minutes until they break down slightly.

Stir in the seeded Scotch bonnet pepper (I remove seeds to reduce heat while keeping flavor) and cook for 1 minute. The pepper will release its signature aroma—this is where the soup gets its signature kick. Add the 1 cup chopped callaloo or cassava and stir for 2 minutes to coat everything in the flavors.

Pour in the 1 cup hot water with the dissolved vegetable bouillon cube and bring to a gentle boil. Reduce heat to medium-low and let it simmer for 10 minutes until the vegetables soften and the flavors meld. This simmering step is crucial—it develops the soup's depth.

Lower the heat to low and gradually whisk in the 1.5 cups coconut milk. Stir constantly for 2-3 minutes to prevent curdling. The coconut should blend smoothly into the soup, creating a velvety texture. Here's the thing—don't let it boil or the coconut will separate.

Add the 1.5 teaspoons salt and 0.5 teaspoon freshly ground black peppercorns, stirring well. Taste and adjust seasoning—this is where you can really personalize the soup. The coconut should be noticeable but not overpowering the other flavors.

Stir in the 0.5 cup fresh lime juice and bring the soup back to a gentle simmer. The lime brightens everything up—you'll see the soup transform from creamy to vibrant. Add the 1 medium sliced ripe plantains and cook for 5 minutes until they're tender and slightly caramelized.

The plantains should be soft enough to eat with a spoon but still hold their shape. If they're cooking too fast, reduce the heat slightly. Here's where it gets fun—taste and adjust the lime if you want more brightness or the coconut if you want more creaminess.

Gently add the 1.5 lb white fish fillets (I use snapper for its firm texture) to the soup. Simmer for 4-5 minutes until the fish is just cooked through—it should flake easily with a fork but still hold together. Overcooking makes fish dry and rubbery.

Remove from heat and stir in the 0.5 cup chopped fresh cilantro. Let the soup rest for 5 minutes before serving—this allows all the flavors to settle together. Serve immediately with warm rice or crusty bread to soak up that delicious broth.

Flavor customization for this dish

Spice Level Control

Belizean fish soup thrives on the Scotch bonnet pepper's signature heat, but you can easily adjust it to your preference. For a milder version, remove the pepper entirely and add ½ teaspoon sweet paprika instead.

If you want to keep the heat but reduce it, use only ¼ of the pepper and remove all seeds and membranes. I’ve found that adding 1 teaspoon honey or agave syrup at the end balances the heat beautifully while adding subtle sweetness. 🌶️

Citrus Variations

The lime juice is essential, but you can experiment with other citrus flavors to suit your taste. Swap in ½ cup fresh orange juice for a sweeter twist, or use ½ cup sour orange juice (if available) for an authentic Belizean touch.

For extra brightness, add 1 teaspoon grated lime zest or orange zest while the soup simmers. If you prefer a tangier profile, increase the lime juice to ⅔ cup and reduce the coconut milk slightly to 1 cup.

Creamy vs. Light Broth

This recipe balances creamy coconut with a light broth, but you can adjust the texture to your liking. For a richer soup, increase the coconut milk to 2 cups and reduce the bouillon water to ½ cup.

For a lighter version, use only 1 cup coconut milk and add ½ cup vegetable broth instead. I’ve also had success replacing half the coconut milk with cashew cream (blend ½ cup soaked cashews with ½ cup water) for a dairy-free option. 🥥
