Cataplana de Marisco
Algarve's spectacular seafood stew of clams, prawns and mussels steamed in a copper cataplana with white wine, chorizo and tomatoes.
About This Recipe
The cataplana is a copper, clamshell-shaped cooking vessel from the Algarve, southern Portugal's sun-drenched coast, and it gives its name to the magnificent seafood feasts cooked inside it. Cataplana de Marisco (seafood cataplana) is the quintessential Algarvian dish: clams, mussels, king prawns and sometimes lobster steamed in their own juices with white wine, onion, garlic, tomatoes, chorizo and fresh herbs. The vessel is sealed shut and set over heat — the steam circulates inside, cooking everything perfectly while concentrating all the flavours into an intensely aromatic broth. Brought to the table still sealed and opened dramatically in front of guests, it is one of Portugal's most theatrical and joyful dining experiences.

Instructions
- 1
Layer the cataplana
Heat the olive oil in the bottom half of an open cataplana (or a wide heavy casserole with a tight-fitting lid) over medium heat. Fry the sliced onions and red pepper for 8 minutes until soft and golden. Add the garlic and chouriço and fry for 2 more minutes.

Seal and steam
Close and latch the cataplana lid firmly (or cover the casserole tightly). Increase the heat to medium-high. Cook sealed for 12–15 minutes — do not open it during cooking, as the steam inside is doing the work.

Check and finish
Open the cataplana away from you (steam will rush out). All the clams and mussels should be wide open — discard any that remain closed. Taste the broth and adjust seasoning. Scatter over the remaining fresh herbs.

Serve at the table
Bring the cataplana to the table and open it dramatically in front of your guests for the full theatrical effect. Serve directly from the vessel with thick crusty bread to mop up the extraordinary broth.

Pro Tips
- →
Purge clams by soaking in heavily salted water (as salty as the sea) for 1 hour before cooking — they will expel any grit.
- →
The broth is the star of the dish; provide plenty of crusty bread for soaking it up.
- →
A real copper cataplana is worth the investment, but a Dutch oven with a tight lid works very well.
- →
Taste and adjust salt at the very end — flavors concentrate as liquids reduce, and a final pinch of flaky salt sharpens the whole dish.
Variations
- •
Add a small lobster or crab, halved, for a more luxurious version.
- •
Stir a tablespoon of tomato paste into the base for a richer, deeper-coloured sauce.
- •
Vegetarian: swap the protein for roasted king oyster mushrooms, smoked tofu or cooked chickpeas — adjust seasoning slightly upward to compensate.
- •
Spicier: add a finely chopped fresh chile or a teaspoon of crushed Aleppo/Urfa pepper to the aromatics for warm, layered heat instead of a single sharp hit.
Storage
Best eaten immediately. Leftover broth can be strained and used as a base for seafood soup the next day.
History & Origin
The cataplana vessel has Moorish origins, dating to the Arab occupation of southern Portugal in the 8th–13th centuries. Its clamshell design predates modern pressure cookers by over a thousand years.
Frequently Asked Questions
Do I need a cataplana vessel?
No — a heavy casserole with a well-fitting lid works perfectly. The key is a sealed, steamy environment.
Can I make this ahead of time?
Yes — most of the components can be prepared up to a day in advance and refrigerated separately. Reheat gently and assemble just before serving so textures stay distinct.
What can I substitute if I don't have all the ingredients?
Stay close to the role each ingredient plays: swap aromatics for similar ones (shallot for onion, lime for lemon), and keep the fat-acid-salt balance intact. Spice blends can usually be approximated with what's in the cupboard.
How do I know it's authentic?
Authenticity sits on a spectrum — what matters more is honoring the technique and balance of flavors. If the dish tastes harmonious and respects how cooks in its home region would build it, you're on solid ground.
