Bocadillo de Calamares Madrileño (Fried Squid Sandwich)

Madrid’s bocadillo de calamares is a straightforward but highly recognisable sandwich: tender squid in a light flour coating, fried until crisp and tucked into a white roll. It is typically served hot and simply dressed, often with lemon and sometimes mayonnaise, so the focus stays on the clean seafood flavour and the crunch of the freshly fried coating. The key to a good version is dryness before dredging and fast frying in hot oil at 180°C (355°F), which keeps the squid crisp rather than greasy. Best eaten immediately, it makes a satisfying lunch or casual snack with very little embellishment needed.

Why this recipe works

  • Light, crisp coating: A simple flour coating gives the squid a delicate crunch without turning the sandwich heavy.
  • Fast cooking: Squid cooks in under two minutes, keeping it tender while the outside turns golden and crisp.
  • Bright finish: Lemon cuts through the fried coating and mayonnaise, keeping each bite fresh rather than greasy.

Authenticity notes

  • Madrid-style serving: Bocadillo de calamares is strongly associated with Madrid’s bars, where it is usually served simply in a white roll with lemon, mayonnaise optional.
  • Keep the garnish simple: The sandwich is typically about the squid itself, so avoid overloading it with strong sauces or heavy toppings.

Texture tips

  • Dry the squid thoroughly: Moisture stops the flour from clinging evenly and can make the coating softer, so pat the rings and tentacles very dry before dredging.
  • Fry briefly: Cook the squid only until lightly golden and crisp; a longer fry can make it rubbery.

Common mistakes

  • Watch the oil temperature: Keep the oil close to 180°C (355°F). Too cool and the squid absorbs oil; too hot and the flour browns before the squid is tender.
  • Fry in batches: Adding too much squid at once drops the oil temperature and makes the coating less crisp.

Make-ahead tips

  • Serve straight away: Fried squid softens quickly, so assemble the sandwich only when you are ready to eat.
  • Hold briefly if needed: If there is a short delay, keep the fried squid on a rack at room temperature and add it to the bread just before serving.

  1. Pat the squid very dry with kitchen paper. Put the plain flour in a bowl and toss the squid in it until well coated, then shake off any excess.
  2. Pour the sunflower oil into a large pot to a depth of about 4 to 5 cm and heat to 180°C (355°F). If you do not have a thermometer, test with a pinch of flour: it should sizzle immediately and turn pale golden within seconds.
  3. Fry the squid in 2 batches for 60 to 90 seconds per batch, until lightly golden and crisp. Lift out with tongs and let it drain briefly in a sieve or colander, then repeat with the remaining squid.
  4. Split the white bread roll and spread the mayonnaise over the base. Pile in the hot fried squid, then squeeze over the lemon juice to taste and close the sandwich.
  5. Serve immediately while the squid is still crunchy. If you like, cut the sandwich in half for easier eating.

Recipe notes

Tips

  • Drying the squid well is the key to a crisp coating and less oil splatter.
  • Keep the oil close to 180°C (355°F): if it is cooler the squid will go greasy, and if it is hotter the flour will brown before the squid is tender.
  • If serving anyone who is pregnant, elderly, or immunocompromised, use pasteurised mayonnaise.

Substitutions

  • Replace the white bread with crusty white bread for a firmer, more traditional bite.
  • Replace the mayonnaise with a thinner spread of mayonnaise for a lighter sandwich.

Storage

  • Best eaten straight away. Fried squid softens quickly; if you must hold it briefly, keep it on a rack at room temperature for up to 20 minutes and assemble just before serving.
