Tuna and White Bean Salad
This is the kind of dish that does not feel like a recipe until you make it and realise it is better than most things that take considerably longer. Tinned tuna, white beans, lemon, good olive oil, a little red onion, and flat-leaf parsley — ten minutes, no cooking, and the kind of result that works equally well as a quick lunch, a side dish for grilled fish, or something to take outside in decent weather.
It is also the dish most likely to change someone's opinion of tinned tuna. The quality of the tin is entirely visible here — there is nothing to hide behind.
The tuna
Use tuna in olive oil. Tuna packed in brine is drier, flatter in flavour, and significantly less good in a preparation where the oil from the tin becomes part of the dressing. For this salad, Açor or José Gourmet's Atlantic tuna both work well — firm enough to break into proper pieces rather than falling apart, and packed in olive oil that carries real flavour into the dish.
If you want to make this into something genuinely special, ventresca — the belly cut — is the version to use. The richness of the belly against the clean, mild cannellini beans is the kind of contrast that earns the dish a permanent place in the rotation. The full [tuna collection] is here.
The recipe (serves two)
- 1 tin good tuna in olive oil
- 1 tin cannellini beans, drained and rinsed
- ½ small red onion, very thinly sliced
- A generous handful of flat-leaf parsley, roughly chopped
- 1 lemon — zest and juice
- Good olive oil
- Salt and black pepper
Soak the sliced red onion in cold water for five minutes before using. This takes the sharp raw edge off without losing the crunch — a small step that makes the salad noticeably better.
Drain and rinse the cannellini beans and tip them into a wide bowl. Add the onion, drained and patted dry, and the parsley. Open the tuna and break it into large pieces over the bowl, tipping in the oil from the tin along with it.
Add the lemon zest, a good squeeze of lemon juice, and a further drizzle of olive oil. Season generously with salt and black pepper. Toss gently — you want the tuna to stay in recognisable pieces rather than breaking down into the beans. Taste, adjust the lemon and seasoning, and serve immediately.
What makes it work
The oil from the tin is not optional — it is the dressing. Adding it directly rather than draining the tuna and starting from scratch with fresh olive oil means the flavour of the fish carries through every element of the salad.
The red onion soak is the other step worth not skipping. Raw onion in a cold salad without soaking has a sharpness that dominates everything else. Five minutes in cold water fixes this completely.
Additions that earn their place
- A tin of good anchovies, two or three fillets torn and laid across the top — the intensity works well against the mildness of the beans
- A handful of halved cherry tomatoes for summer
- A few capers scattered through — their brine sharpens the whole dish
- Thinly sliced celery for extra crunch alongside the beans
- A soft-boiled egg per person alongside, which turns this into a more substantial meal
One variation worth knowing
The Tuscan version of this salad — fagioli e tonno — uses the same base but adds thinly sliced raw fennel in place of the red onion. The anise note of the fennel sits particularly well against the olive oil-packed tuna and gives the salad a slightly more considered, slightly more Italian character. Both versions are worth knowing.
Serving
This salad is best eaten at room temperature, not cold from the fridge — cold dulls the olive oil and flattens the lemon. If you are making it ahead, dress it at the last minute rather than letting it sit.
Good bread alongside, for mopping. That is the complete picture.
