Cazuela de Fideos (Catalan Noodle Casserole with Seafood)

In Catalan-style cazuela de fideos, short pasta is cooked directly in a savoury seafood broth so the noodles absorb the flavour rather than sitting in a separate sauce. This version uses a jammy tomato and onion base, saffron, dry white wine and fish stock to create a golden, aromatic broth, then finishes with mussels, prawns, white fish and peas. The result sits between a noodle stew and a casserole: glossy, brothy enough to ladle, but concentrated and satisfying. Fresh parsley and lemon keep the seafood bright, making it well suited to a relaxed dinner served straight from the pot.

Why this recipe works

  • A deeply savoury base: Slowly softened onion, garlic, grated tomato, saffron, wine and fish stock create a rounded broth before the noodles go in.
  • Built in one pot: The noodles cook directly in the seafood broth, absorbing flavour while keeping the method streamlined.
  • Bright finish: Lemon and parsley lift the richness of the seafood and saffron broth just before serving.

Ingredient notes

  • Choose fresh mussels carefully: Use mussels with intact shells that close when tapped, and discard any that remain closed after cooking.
  • Use saffron sparingly but deliberately: Crushing the threads before adding them helps release their colour and aroma into the broth.
  • Grate the tomato: Grated ripe tomato cooks down quickly into a jammy base, giving the broth body without large pieces of skin.

Timing notes

  • Prep before heating the pot: Clean the mussels, chop the aromatics and portion the seafood first, as the cooking moves quickly once the noodles are added.
  • Let the noodles settle briefly: A short rest off the heat helps the fideos absorb the last of the broth and turn glossy.
  • Serve straight away: The seafood is at its best just cooked, while the noodles are still tender and the broth remains loose.

Texture tips

  • Keep seafood gentle: Once the fish and prawns go in, maintain a gentle simmer so the fish stays tender and the prawns do not toughen.
  • Loosen if needed: If the noodles absorb too much broth before serving, add a little hot fish stock and let it settle briefly.
  • Rest before ladling: Taking the pot off the heat for a couple of minutes gives the broth a more cohesive, glossy finish.

Authenticity notes

  • Catalan-style noodle cooking: This style uses short fideo noodles with a seafood broth and tomato base, giving a result that sits between a stew and a dry noodle rice-style dish.
  • Flavour starts with the sofrito-style base: Cooking the onion, garlic and tomato until sweet and concentrated is key to the depth of the finished broth.
  • Lemon at the table: Serving with lemon wedges is a simple way to balance the seafood and saffron without masking the broth.

  1. Prepare the seafood: rinse the mussels and discard any that are cracked or do not close when tapped. Cut the fish into bite-size chunks, and pat the prawns dry. Finely chop the onion and garlic, grate the tomatoes, and roughly chop the parsley.
  2. Heat the olive oil in a large pot over medium heat. Add the onion with a pinch of salt and cook for 6 to 8 minutes until soft and sweet, then stir in the garlic for 1 minute until fragrant.
  3. Stir in the grated tomato and cook for 6 to 8 minutes, stirring often, until thickened and jammy. Crush the saffron between your fingers, add it to the pot, then pour in the wine and simmer for 2 minutes to cook off the alcohol.
  4. Pour in the fish stock and bring to a lively simmer. Stir in the fideo noodles and cook for 6 minutes, stirring now and then so they do not stick.
  5. Add the peas and mussels, cover, and cook for 3 to 4 minutes until the mussels open. Add the fish and prawns and simmer gently for 3 to 5 minutes until the fish is opaque and the prawns are pink; discard any mussels that stay closed.
  6. Take the pot off the heat and rest for 2 minutes so the noodles turn glossy and the broth settles. Stir through most of the parsley, then squeeze over half the lemon. Serve straight away with the remaining parsley and lemon wedges for squeezing.

Recipe notes

Tips

  • Keep the simmer gentle once the fish and prawns go in, so the seafood stays tender and the broth remains clear.
  • If the casserole looks a touch tight before serving, loosen it with a splash of hot fish stock and rest for 1 minute before ladling up.
  • Seafood safety: discard any mussels that do not open during cooking, and make sure the prawns are fully pink and the fish is opaque before serving.

Substitutions

  • Replace Dry White Wine with the same amount of Fish stock for an alcohol-free version.
  • Replace White fish fillet with Cod fillet for a firmer, flakier finish.
  • Replace Fresh parsley with Fresh basil for a softer, sweeter herb note.

Storage

  • Refrigerate up to 2 days
  • Cool quickly, then refrigerate in a sealed container. Reheat gently in a saucepan with a splash of fish stock until piping hot, stirring carefully so the fish does not break up; mussels are best eaten on the day.
