Finished with lime and fresh cilantro, this comforting one-pot meal is both rustic and elegant—perfect for weeknight dinners or special gatherings.
Steps
Before you start
- Have all seafood cleaned and cut to size before you begin—once the broth is simmering, you'll add proteins quickly to avoid overcooking
- Peel and cut the plantain just before cooking; green plantains discolor when exposed to air for too long
- Toast the achiote seeds in the pot before adding oil to unlock their color and earthy flavor
Toast achiote and infuse oil
- Place a large heavy-bottomed pot or Dutch oven over medium heat.
- Add the achiote seeds and toast for about 1 minute, stirring constantly, until fragrant and the kitchen smells warm and earthy.
- Add the olive oil and let the seeds steep for 2–3 minutes.
- Do not let the oil smoke.
- Strain out the seeds using a fine mesh strainer if desired (or leave them in for deeper color and flavor), leaving the infused oil in the pot.

Ready when: Oil is a deep reddish-orange and smells warm and fragrant
Tip: Don't skip toasting the achiote seeds—it brings out their subtle annatto flavor and ensures even color throughout the broth
Sauté aromatics
- Add the diced onion and cook for 3–4 minutes, stirring occasionally, until softened and slightly golden at the edges.
- Add the minced garlic and diced red bell pepper, and cook for another 2–3 minutes, stirring frequently, until the pepper begins to soften and the mixture is fragrant.

Ready when: Onions are translucent and edges are light golden; pepper is slightly tender
Tip: Cook the garlic with the pepper so it doesn't burn while waiting for the pepper to soften
Bloom tomato paste and spices
- Stir in the tomato paste and cook for 1–2 minutes, stirring often.
- Add the ground cumin and dried oregano, stirring constantly for about 1 minute until the spices are fully combined and the tomato paste darkens slightly.

Ready when: Paste is darker in color and spices are fragrant
Tip: Blooming the paste and spices in the oil develops deeper, more complex flavors
Add stock and plantain
- Pour in the fish or seafood stock and add the coconut milk.
- Stir well to combine.
- Add the green plantain chunks and bring the broth to a simmer over medium-high heat.
- Once simmering, reduce the heat to medium and maintain a gentle simmer.

Ready when: Broth is at a gentle rolling simmer; plantain begins to soften
Tip: Green plantain takes longer to cook than pasta, so let it have a head start
Add pasta
- Break the vermicelli into 2–3 inch (5–7.5 cm) pieces by hand and add to the simmering broth.
- Stir well to separate the strands.
- Maintain a gentle simmer and cook for 6–8 minutes, stirring occasionally, until the pasta is nearly tender but still has a slight bite.

Ready when: Pasta is almost tender; plantain is almost cooked through
Tip: Breaking the vermicelli into shorter pieces makes the soup easier to eat and more authentic in style
Add white fish
- Add the white fish chunks to the simmering broth.
- Stir gently to distribute evenly.
- Cook for 3–4 minutes until the fish is nearly opaque throughout and the internal flesh is starting to flake when prodded with a fork.

Ready when: Fish is nearly opaque in the center and begins to flake
Tip: Don't stir the fish too much once it's in the pot—gentle movement keeps the chunks intact
Add shrimp and optional crab
- Add the peeled and deveined shrimp to the pot.
- If using crab meat, add it now as well.
- Stir gently to combine.
- Cook for 2–3 minutes, until the shrimp are pink and opaque throughout and the crab is warmed through (crab meat is already cooked, so it just needs warming).

Ready when: Shrimp are bright pink and opaque; internal temperature reaches 145°F (63°C)
Tip: Shrimp cooks very quickly—overcooked shrimp becomes tough and rubbery, so watch carefully
Season and finish
- Taste the broth and adjust seasoning with kosher salt and freshly ground black pepper as needed.
- The soup should be savory, coconut-rich, and slightly warm from the achiote.
- Ladle into bowls and garnish generously with fresh cilantro, scallion greens if using, and lime wedges on the side for squeezing at the table.

Ready when: Soup tastes balanced and vibrant; all ingredients are cooked through
Tip: Fresh lime squeezed at the table brightens the rich, coconut broth and is essential to the authentic flavor
Good to know
Tips
- Achiote (annatto) seeds are the key to authentic Belizean flavor and color—they give the broth a warm, earthy tone that can't be replicated. Find them in Latin American markets or online.
- Buy shrimp and fish from a reliable fishmonger if possible—fresh seafood is far superior to frozen, and the difference is noticeable in a broth-based soup where timing is critical.
- Green plantain has a starchy, slightly bitter flavor that balances the sweetness of coconut; using ripe (yellow) plantain will make the soup sweeter and less authentic.
- Lime is not optional—the brightness of fresh citrus is essential to balancing the rich, coconut-forward broth and is how this soup is traditionally finished at the table.
Make ahead
Prep all ingredients (dice vegetables, peel plantain and seafood) up to 4 hours ahead; store vegetables in the fridge in separate containers, and keep seafood on ice. Do not cook the soup in advance—it's best made fresh and served immediately so the seafood stays tender and the broth maintains its vibrant flavors.
Storage & reheating
Store leftover soup in an airtight container in the refrigerator for up to 2 days. Do not freeze; seafood becomes tough and pasta absorbs too much liquid when thawed. To reheat, warm gently on the stovetop over medium-low heat, adding a splash of water or stock if the soup has thickened, and taste for seasoning adjustment.
Substitutions
- white fish fillet (snapper, mahi-mahi, or grouper) → cod, halibut, or sea bass. Use firm white fish fillets that hold their shape during simmering; avoid delicate fish like flounder
- large shrimp, peeled and deveined → large scallops or squid. Scallops should be added in the same time window; squid should be thinly sliced to cook through in 2–3 minutes
- unsweetened coconut milk (full-fat) → 1 cup (240 ml) of heavy cream mixed with ½ cup (120 ml) water. This won't replicate the authentic flavor, but works if coconut milk is unavailable; add it slowly while tasting
- green plantain → green banana, yam, or 1 lb (450 g) diced potato. Green banana will have a slightly different texture; potato cooks faster, so add it with the pasta instead of at step 4
