Tuna and White Bean Salad with Dijon Dressing

Tuna and white bean salad is a no-cook lunch with the substance of a main-course salad and the freshness of a simple vinaigrette. Creamy canned white beans give it body, while flaked tuna adds savoury depth without needing anything more than draining and gentle tossing. The Dijon, lemon and extra-virgin olive oil dressing brings sharpness and gloss, cutting through the richness of the beans and fish. Red onion, cherry tomatoes and parsley keep the bowl bright, crisp and fresh. It is best served straight away or after a short rest, when the dressing has had time to settle into the beans without softening the herbs.

Texture tips

  • Drain the beans well: Rinsing and draining the beans thoroughly keeps the dressing sharp rather than watery.
  • Keep the tuna in flakes: Toss gently after adding the dressing so the tuna stays in larger pieces instead of breaking down.

Ingredient notes

  • Choose the tuna to suit the finish: Tuna packed in olive oil gives a richer salad, while tuna in spring water keeps the dressing lighter and brighter.
  • Adjust the lemon at the end: Taste after tossing and add a little more lemon juice if the beans have softened the sharpness of the dressing.
  • Use fresh herbs: Fresh parsley gives the cleanest finish; dill is a good alternative if you want a more pronounced herbal note.

Make-ahead tips

  • Make ahead for lunch: The salad can be stored in an airtight container in the fridge for up to 2 days.
  • Add herbs just before serving: Keep the parsley back if preparing in advance, then stir it through at the end for fresher flavour.
  • Refresh before eating: If the salad looks a little dry after chilling, toss it with a squeeze of lemon juice before serving.

Serving ideas

  • Serve with bread: Crusty bread, toast or flatbread makes it a more complete lunch.
  • Spoon over leaves: Serve over crisp salad leaves for a lighter plate with extra freshness.
  • Finish simply: A little extra parsley, black pepper or lemon zest gives a clean final lift.

  1. Drain and rinse the white beans, then tip into a mixing bowl. Drain the tuna and flake it into the bowl in large pieces.
  2. In a small bowl, whisk together the Dijon mustard, the juice of the lemon, olive oil, fine sea salt and black pepper until emulsified. Taste and adjust with a little more lemon juice if you want it sharper.
  3. Thinly slice the red onion, halve the cherry tomatoes, and finely chop the parsley. Add them to the bowl with the beans and tuna.
  4. Pour over the dressing and toss gently so the tuna stays in flakes. Serve straight away, or leave for 5 minutes for the flavours to mingle.

Recipe notes

Tips

  • For the best texture, rinse the white beans well and let them drain for a minute so the dressing does not get diluted.
  • If serving later, keep the parsley back and stir it through just before eating for the freshest flavour.

Substitutions

  • Replace Dijon mustard with whole-grain mustard for a coarser texture.
  • Replace lemon with lime for a slightly more aromatic, sharper dressing.
  • Replace fresh parsley with fresh dill for a more pronounced herbal note.

Storage

  • Refrigerate up to 2 days
  • Store in an airtight container in the fridge. Stir well before serving; if it looks a little dry, squeeze in a little extra lemon juice and toss again.
