💡 Tips

  • Use carolino rice if possible because its plump grains release starch while still keeping a pleasant bite in a brothy dish.
  • Keep the stock hot before adding it to the rice so the simmer stays steady and the seafood cooks evenly.
  • Serve as soon as the shellfish open; waiting too long makes the rice dry and the shrimp rubbery.

⚠️ Common Mistakes

  • Cooking the rice until dry like paella

    ✅ Fix: Keep extra hot stock nearby and finish with a loose, spoonable texture.

  • Adding all seafood at the beginning

    ✅ Fix: Stage the squid, fish, shrimp, and shellfish so each cooks just until tender.

  • Using bland stock

    ✅ Fix: Simmer the shrimp shells in part of the stock to create a deeper seafood base.

🧊 How to Store

Refrigerate leftovers in a sealed container for up to 1 day, but remove shellfish from their shells first. Reheat gently in a saucepan with 100 to 150 ml water or stock per portion until steaming hot; do not reheat more than once.

📅 Make Ahead

The refogado and enriched seafood stock can be made up to 1 day ahead and refrigerated separately. Cook the rice and seafood only just before serving so the grains stay loose and the shellfish remain tender.

🍽️ Pairs Well With

  • Crusty Portuguese bread

Instructions

  1. 1

    Inspect the clams and mussels before cooking, discarding any cracked shells and any open shells that do not close when tapped. Keep the prepared shellfish chilled while you build the base, because fresh shellfish should go into the pot cold and still alive.

  2. 2

    Peel the shrimp, leaving a few whole for garnish if desired, and reserve the shells. Put the shells in a small saucepan with 300 ml of the measured fish stock, simmer for 10 minutes, then strain and return this enriched liquid to the remaining hot stock.

  3. 3

    Warm the olive oil in a wide heavy pot or cataplana-style pan over medium heat. Add the onion, bay leaves, and 3 g of the salt, then cook for 8 minutes until the onion is soft, sweet, and lightly golden without browning hard.

  4. 4

    Stir in the garlic, tomato paste, paprika, black pepper, and piri-piri sauce, cooking for 1 minute until fragrant. Add the chopped tomatoes and cook for 7 minutes, stirring often, until the mixture thickens into a rusty-red refogado.

  5. 5

    Pour in the white wine and scrape the bottom of the pot to release any concentrated tomato and onion. Simmer for 3 minutes so the alcohol cooks off and the sauce tastes rounded rather than sharp.

  6. 6

    Stir in the carolino rice until every grain is coated with the tomato base. Add 900 ml of the hot enriched stock and the remaining 6 g of salt, bring to a lively simmer, and cook uncovered for 10 minutes, stirring occasionally so the rice does not stick.

  7. 7

    Add the squid and monkfish, folding them gently into the rice without breaking the fish. Continue simmering for 5 minutes, adding up to 300 ml more hot stock as needed to keep the dish loose and soupy.

  8. 8

    Add the clams, mussels, and peeled shrimp, then cover the pot and cook for 5 to 7 minutes. The shrimp should turn pink, the mussels and clams should open, and any shellfish that remain closed after cooking must be discarded.

  9. 9

    Remove the bay leaves and check the consistency before serving. Arroz de Marisco should be wetter than risotto, so stir in a final 100 ml of hot stock or water if the rice has tightened too much.

  10. 10

    Fold in most of the chopped cilantro and let the pot stand off the heat for 3 minutes. Serve immediately in warm bowls with the remaining cilantro and lemon wedges, because the rice will continue absorbing broth as it sits.
