📝 About This Recipe

Transport your senses to the sun-drenched shores of the Mediterranean with this authentic Sopa de Marisco. This elegant Spanish classic is built upon a foundation of deep, saffron-infused fumet and a rich 'sofrito' of sweet peppers and tomatoes. It is a luxurious celebration of the sea, combining succulent prawns, tender hake, and briny mussels into a soul-warming bowl that defines Spanish coastal hospitality.

🥗 Ingredients

The Seafood

  • 12-16 pieces Large Prawns or Shrimp (shell-on, heads intact for the stock)
  • 500 grams Fresh Mussels (cleaned and debearded)
  • 400 grams Firm White Fish (Hake, Monkfish, or Cod) (cut into 1-inch bite-sized cubes)
  • 250 grams Squid or Calamari (cleaned and sliced into rings)

The Aromatic Base (Sofrito)

  • 4 tablespoons Extra Virgin Olive Oil (Spanish Picual variety recommended)
  • 1 large Brown Onion (very finely diced)
  • 1/2 piece Red Bell Pepper (finely minced)
  • 3 pieces Garlic Cloves (minced)
  • 2 large Ripe Tomatoes (grated, discarding the skin)
  • 1 teaspoon Spanish Sweet Pimentón (Paprika) (ensure it is not the spicy variety)

The Liquid and Seasoning

  • 1.5 liters Homemade Fish Stock (Fumet) (hot)
  • 150 ml Dry White Wine (Albariño or Verdejo) (high quality)
  • 1 pinch Saffron Threads (toasted and crushed)
  • 1 handful Fresh Parsley (finely chopped)
  • to taste Salt and White Pepper

👨‍🍳 Instructions

  1. 1

    Begin by peeling the prawns. Reserve the meat in the fridge, but keep the heads and shells. In a small pot with a splash of oil, sauté the shells and heads for 3 minutes until bright red, then crush them with a wooden spoon to release their juices.

  2. 2

    Add 200ml of your fish stock to the shells, simmer for 5 minutes, then strain this concentrated 'essence' through a fine-mesh sieve and set aside to add to the main soup later.

  3. 3

    In a large heavy-bottomed pot or 'cazuela', heat the olive oil over medium-low heat. Add the onion and red pepper, sautéing slowly for 10-12 minutes until translucent and soft.

  4. 4

    Stir in the minced garlic and cook for 1 minute until fragrant. Add the grated tomato and cook for another 8 minutes until the liquid has evaporated and the mixture is thick and jammy.

  5. 5

    Remove the pot from the heat momentarily and stir in the pimentón. Return to heat and immediately pour in the white wine, scraping the bottom of the pan to deglaze.

  6. 6

    Pour in the remaining fish stock and the prawn shell essence. Bring to a gentle boil, then reduce heat to low and simmer for 15 minutes to allow flavors to meld.

  7. 7

    While the soup simmers, bloom your saffron threads in a tablespoon of warm water for 5 minutes, then stir it into the pot.

  8. 8

    Add the squid rings to the pot and cook for 5 minutes, as they require slightly more time than the other seafood.

  9. 9

    Gently slide the fish cubes and the peeled prawn meat into the simmering liquid. Cook for 3-4 minutes.

  10. 10

    Finally, add the mussels. Cover the pot with a lid for 2-3 minutes until the mussels have opened wide. Discard any that remain closed.

  11. 11

    Taste the broth and adjust the seasoning with salt and a pinch of white pepper. Stir in the fresh parsley just before serving.

💡 Chef's Tips

Always use homemade or high-quality fish stock; a bouillon cube will never achieve the same depth of flavor. Don't overcook the seafood—add the fish and prawns last so they remain tender and succulent. Toasting the saffron threads in a dry pan for 30 seconds before crushing them releases significantly more aroma. If you prefer a thicker soup, you can blend a small portion of the finished sofrito with a few fried almonds and bread before adding the stock. Always clean your mussels thoroughly and remove the 'beard' just before cooking to ensure the broth stays grit-free.

🍽️ Serving Suggestions

Serve in wide, shallow bowls with a generous slice of toasted sourdough rubbed with garlic. Pair with a crisp, chilled Spanish white wine like an Albariño or a dry Sherry (Manzanilla). A side of 'Alioli' (garlic mayonnaise) can be swirled into the soup for a richer, creamier texture. Follow the meal with a light green salad to balance the richness of the seafood. Garnish with an extra drizzle of high-quality extra virgin olive oil and a lemon wedge on the side.
