Let's cook

  1. Use tuna in oil

    Oil-packed tuna is far more flavourful and less dry than water-packed. Drain it but do not press it bone dry.

  2. Flake, do not mash

    Break the tuna into flakes with a fork, keeping some texture. Mashed tuna turns into paste.

    💡

    Chunks make a much better sandwich than a uniform spread.

  3. Add crunch

    Fold in the celery and red onion. The crunch is what keeps the filling from being one-note and heavy.

  4. Dress and season

    Stir in the mayonnaise, Dijon, capers, lemon juice, dill, salt, and plenty of black pepper. Taste — it usually needs more lemon than you expect.

  5. Build on sturdy bread

    Layer lettuce first as a barrier, then the tuna, then tomato. Lettuce underneath stops the bread going soggy.

📝 Tips, swaps, and make-ahead notes

The filling keeps 3 days refrigerated and is better after an hour as the flavours settle. Assemble sandwiches to order rather than in advance.

  • Lighter: Swap half the mayonnaise for Greek yoghurt.
  • Melt: Top with cheese and grill open-faced for a tuna melt.
  • Gluten-free: Serve in lettuce cups or on GF bread.
