Cazuela de Fideos con Almejas (Spanish Clam Noodle Casserole)

Cazuela de fideos con almejas sits somewhere between a noodle stew and a seafood casserole, with short fideo noodles cooked directly in a savoury shellfish broth. Toasting the noodles first gives them a nutty depth and helps them hold their shape as they absorb the fish stock, tomato, garlic and white wine. Fresh clams bring briny sweetness and open in the pot, flavouring the broth as they cook. Finished with parsley, lemon and olive oil, it is a simple Spanish-style one-pot dinner best served immediately, while the noodles are tender and the broth is lively.

Why this recipe works

  • Layered seafood flavour: Tomato, garlic, white wine and fish stock create a savoury base that the noodles absorb as they cook.
  • Toasted fideo: Browning the noodles first adds a nutty depth and helps them stay distinct rather than turning soft too quickly.
  • Serve straight from the pot: The dish is designed for relaxed table serving, with lemon and olive oil added at the end for freshness and richness.

Ingredient notes

  • Choose fresh, live clams: Use clams with intact shells and discard any that are cracked or remain open when tapped before cooking.
  • Use a dry white wine: A dry wine keeps the broth savoury and balanced; if avoiding wine, use extra fish stock and finish with lemon for brightness.
  • Grate ripe tomato: Grating the tomato helps it melt into the base quickly, giving the broth body without large pieces of skin.

Timing notes

  • Best served immediately: The noodles continue to absorb liquid as they sit, so serve the casserole as soon as the clams have opened and the fideo is just tender.
  • Prep the clams first: Scrub and check the clams before starting the base so they can go into the pot as soon as the broth is ready.

Common mistakes

  • Do not overcook the clams: Once most shells have opened, take the pot off the heat; prolonged simmering can make the clams tough.
  • Avoid skipping the noodle toasting: Untoasted fideo can become softer and less flavourful in the broth, losing the nutty character of the dish.
  • Handle leftovers carefully: Cool leftovers quickly, refrigerate, and reheat gently until piping hot; discard any clams that did not open during cooking.

Authenticity notes

  • A practical Spanish-style cazuela: The dish follows the home-cooking logic of a cazuela: a simple sofrito-style base, toasted noodles and seafood cooked together in one pot.
  • Pantry-friendly tomato option: Fresh ripe tomato gives the cleanest flavour, but canned chopped tomatoes can be used when good fresh tomatoes are unavailable.

  1. Rinse the clams well, scrubbing the shells, and discard any that are cracked or stay open when tapped. Finely chop the onion, slice the garlic, and grate the tomatoes. Finely chop the parsley and cut the lemon into wedges.
  2. Heat 2 tbsp of the olive oil in a cazuela or Dutch oven over medium heat. Add the fideo noodles and toast, stirring often, for 3 to 5 minutes until deep golden. Tip into a bowl and set aside.
  3. Add the remaining 1 tbsp olive oil to the pot, then cook the onion with a pinch of the fine sea salt for 5 to 7 minutes until softened. Stir in the garlic and cook for 30 to 60 seconds until fragrant. Add the grated tomato and simmer for 6 to 8 minutes until slightly reduced and jammy.
  4. Pour in the dry white wine and simmer for 2 minutes to cook off the raw alcohol. Add the fish stock and bring to a lively simmer. Taste and season with a little more fine sea salt if needed.
  5. Stir in the toasted fideo noodles, then add the clams and cover. Simmer for 6 to 10 minutes, shaking the pot once or twice, until the clams have opened and the noodles are just tender. Discard any clams that do not open.
  6. Take off the heat and scatter over the fresh parsley. Serve straight from the pot with lemon wedges for squeezing over at the table. If you like, finish with an extra drizzle of extra virgin olive oil from the bottle.

Recipe notes

Tips

  • Toast the fideo noodles until evenly golden; this keeps them pleasantly separate and adds a nutty depth to the broth.
  • Keep the simmer gentle once the clams go in so they open without turning tough; remove the pot from the heat as soon as most shells have opened.
  • Food safety: discard any clams with broken shells, and always throw away any that do not open after cooking.

Substitutions

  • Replace Dry White Wine with the same amount of Fish stock, plus a squeeze of Lemon at the end to brighten the flavour.
  • Replace Tomato with 400 g Canned chopped tomatoes for a more pantry-friendly version; simmer a few minutes longer to reduce.

Storage

  • Refrigerate up to 1 days
  • Best eaten straight away. If you have leftovers, cool quickly and refrigerate; reheat gently in a large pot with a splash of fish stock until piping hot, and discard any clams that were not already opened.
