Tramezzini al Tonno e Capperi (Italian Tuna and Caper Sandwiches)
Why this recipe works
- Ready in minutes: Canned tuna and a no-cook filling keep the recipe fast enough for an everyday lunch.
- Bright, balanced filling: Lemon juice and zest cut through the richness of the mayonnaise and keep the tuna tasting fresh.
- Soft but not flat: Creamy tuna, briny capers and tender white bread give the sandwiches their classic tramezzini texture.

Ingredient notes
- Choose good tuna: Use well-drained canned tuna so the filling stays creamy rather than wet.
- Check the capers first: Capers vary in saltiness, so rinse very salty ones and taste the filling before adding extra salt.
- Use soft sandwich bread: Tramezzini depend on tender white bread; firmer or rustic loaves will give a less classic texture.
Texture tips
- For a neater filling: Mix until the tuna is creamy but still slightly textured, which helps the sandwiches hold together without becoming paste-like.
- Avoid soggy bread: Drain the tuna thoroughly and avoid adding more lemon juice than needed for brightness.
- Chill before cutting: A short chill helps the filling firm up, making cleaner triangles for serving.
Make-ahead tips
- Make the filling ahead: The tuna mixture can be prepared in advance and kept chilled, then spread onto the bread shortly before serving.
- Best texture strategy: For the freshest bread, store the filling separately and assemble the sandwiches closer to eating.
- Serve within a day: Assembled tramezzini are best eaten the same day and should be kept refrigerated until needed.
Serving ideas
- Serve with simple sides: Pair with crisp salad leaves, olives or lightly salted crisps for an easy lunch plate.
- Cut into triangles: Trim the crusts and cut each sandwich diagonally for the classic tramezzini shape.
- Keep drinks light: Serve with sparkling water, iced tea or a dry Italian-style aperitif for a simple café-style pairing.

Ingredients
Instructions
- In a mixing bowl, combine the tuna, capers and mayonnaise. Finely grate in a little lemon zest, then squeeze in 1 to 2 tablespoons of lemon juice. Season with the salt and black pepper, then mix until creamy but still a little textured.
- Lay out the bread and spread the tuna mixture evenly over 4 slices, right to the edges. Top with the remaining slices and press gently so the filling sits neatly.
- Trim the crusts if you like, then cut each sandwich into triangles. Serve straight away, or chill for 10 minutes for a firmer, cleaner cut.
Recipe notes
Tips
- Rinse the capers briefly and pat dry if they are very salty, then taste the filling before adding more fine sea salt.
- For the soft tramezzini texture, press the sandwiches lightly and let them sit for a couple of minutes before cutting so the filling settles.
- If serving to pregnant people, young children, or anyone immunocompromised, use tuna that is within date and keep the sandwiches well chilled until serving.
Substitutions
- Replace Mayonnaise with avocado-oil-mayonnaise for a slightly lighter flavour.
- Replace Capers with chopped dill-gherkin-pickles for a similar briny bite.
Storage
- Refrigerate up to 1 days
- Store in an airtight container in the fridge and eat within 24 hours. For best texture, cut just before serving; if the bread dries slightly, refresh with a small squeeze of lemon.
