About Sopa de Mariscos
Sopa de Mariscos is a true delicacy of Costa Rican cooking, delivering a slice of Caribbean living straight to your plate. The dish brings together the freshest seafood — prawns, squid and mussels — in an aromatic broth. That broth is often enriched with herbs and spices such as coriander, garlic and chilli, lending it real depth and intensity. Served as a starter or as a hearty main course, Sopa de Mariscos is a genuine treat for any lover of seafood.
Ingredients (serves 1–2)
- 200g prawns, peeled and deveined
- 100g squid, cut into rings
- 100g mussels, fresh or frozen
- 1 onion, chopped
- 2 cloves of garlic, chopped
- 1 pepper, diced
- 1 tomato, diced
- 1 litre fish stock or vegetable stock
- 1 tablespoon olive oil
- Fresh coriander, to garnish
- Salt and pepper to taste
Shopping for the ingredients
For your Sopa de Mariscos, choose the freshest ingredients you can to draw out the best flavour. A visit to a local fish market is the surest way to find the freshest seafood. Be sure to pick up aromatic herbs such as coriander too, as they are essential to the character of the dish. If fresh ingredients are hard to come by, good-quality frozen produce makes a perfectly reliable alternative.
Preparing the dish
Before you start cooking the Sopa de Mariscos, get all your ingredients ready. Wash and chop the vegetables carefully so the flavours are evenly distributed. Make sure the seafood is thoroughly cleaned as well, to guarantee a hygienic preparation. One step that is often overlooked is snipping the fresh herbs you plan to use as a garnish later on.
Step-by-step instructions
- Heat the olive oil in a large pot and add the chopped onion and garlic. Fry both over medium heat until golden brown.
- Add the diced pepper and tomato and let them soften briefly.
- Pour the fish stock or vegetable stock into the pot and bring the mixture to the boil.
- Add the prawns, squid and mussels to the pot. Let the soup simmer for about 5–7 minutes, until the seafood is cooked through.
- Season the soup with salt, pepper and fresh coriander. Serve hot in pre-warmed bowls and garnish to taste.
Gluten-free / lactose-free version
Sopa de Mariscos is naturally gluten-free and lactose-free, as long as you make sure the stock you use contains no additional ingredients. When buying stock, check that it is free from gluten so your dish stays easy to digest. You should also make sure the seafood you use is free from fillers that could trigger allergies. That way, even people with intolerances can enjoy this delicious dish.
Tips for vegans and vegetarians
For vegans and vegetarians, the Sopa de Mariscos is easy to adapt by swapping the seafood for a variety of vegetables and pulses. Use chickpeas, courgette, carrots or green beans, for example, to create a hearty vegetable broth. Thanks to the range of spices and aromatic herbs, the flavour can still be intense and layered. This way you keep all the enjoyment of a traditionally inspired but fully plant-based dish.
More tips and tricks
To give your Sopa de Mariscos a special touch, you can add spices such as paprika or even a warm blend of your choosing. Experiment with different stocks, too, to achieve just the flavour you want. A squeeze of lime juice just before serving brightens the dish beautifully. You can also serve the soup with crusty bread or tortillas to make it a complete meal, much as you might alongside a plate of Patacones.
Adapting the recipe to your taste
The lovely thing about Sopa de Mariscos is how easily it adapts to personal preference. Add more or fewer of your favourite shellfish to shape the soup to your own taste. If you like things spicier, work in extra chillies or even a few drops of hot sauce. The broth is variable too: whether you make it rich or mild, the result is always a treat.
Ingredient substitutions
If you find yourself short of certain ingredients for the Sopa de Mariscos, there are plenty of alternatives to hand. Instead of squid, you could use peeled crab or scallops. Firm fish such as salmon or cod can also be added to the broth, in the spirit of a dish like Atún en Salsa de Coco. This flexibility lets you vary the recipe to suit your taste while keeping it easy to put together.
Drink pairing ideas
Refreshing drinks are a wonderful match for your Sopa de Mariscos. A cold, light beer is a popular choice, as it complements the flavours of the seafood nicely. Alternatively, you could mix up a white sangria or a fruity mojito to underline the Caribbean atmosphere. The joy here is that these drinks come in endless variations to delight the palate.
Serving and presentation ideas
For the best presentation of your Sopa de Mariscos, use deep bowls and garnish the dish with fresh coriander and lime wedges. Make sure the soup is served piping hot so its aroma really shines. A side of crusty bread or tortillas can heighten the visual appeal even further. Pay attention to an inviting table setting to bring out that Caribbean flair.
