It started with the classic fridge-staring contest: "what can I make without eggs?" I had my heart set on a proper Niçoise, the whole glamorous lot, but the fridge had other plans. No eggs, no potatoes, just one very judgy light bulb and a lonely lemon rolling about like it owned the place. So I did what any hungry home cook does and raided the cupboard, and oh, thank goodness I did! Hiding at the back were three tins of silky tuna in olive oil and a jar of briny green olives, and just like that, this Niçoise-Style Tuna & Green Bean Salad was born. Dinner went from disaster to Mediterranean holiday in about ten seconds flat.
The Fresh Mediterranean Lineup
Here's the beauty of this salad: it's all about a handful of honest, vibrant ingredients doing what they do best. Oil-packed tuna brings a silky, decadent richness that its water-packed cousin can only dream about, while crisp green beans, snappy red onion, sweet tomatoes and a squeeze of fresh lemon keep every forkful bright and lively. No fancy shopping trip, no fuss, just good stuff working together.
Just a few pantry staples and crisp green beans - nothing fancy required.
🔍 What's Hiding in Your Bowl (Besides Flavour)
Tuna - Rich in lean protein, selenium, vitamin B12, and niacin. Also provides omega-3 fatty acids, linked to heart and brain health.
Extra virgin olive oil - contains heart-healthy monounsaturated fats and polyphenols with anti-inflammatory properties.
Tomato - Rich in lycopene (an antioxidant linked to heart health and cancer-risk reduction), vitamin C, and potassium.
Green beans - Low in calories and a good source of fibre, vitamin K, vitamin C and folate. They're the bulk of the salad, so they do a lot of the nutritional work.
Mixed salad leaves - Rich in folate, vitamin K and carotenoids like lutein, and spinach and rocket also contain natural nitrates, which support healthy blood flow.
Master the 30-Second Flash Blanch
The Shock Treatment
I know, I know, blanching sounds like one more pot to wash. But hear me out: those 30 little seconds are the difference between squeaky, grassy beans and gloriously snappy, electric-green ones. A tiny bit of effort for a big payoff, and honestly the sneaky secret that makes this salad taste like you tried far harder than you did.
Assemble and Drizzle
Now for my favourite part: the piling on. This salad is happily rustic and generous, with big flaky chunks of tuna and that gorgeous liquid gold from the tin doing double duty as dressing. Add a lemony squeeze and a flurry of flaky sea salt and you've basically got a holiday on a plate. No judgement if you eat it standing at the counter.
What started as a "what can I make without eggs?" moment turned into my go-to 15-minute Mediterranean bowl. If you make this Niçoise-Style Tuna & Green Bean Salad, I would love to see it! Tag your creations on Instagram @homecookingwithmax
Tuna & Green Bean Salad
Niçoise-Inspired Salad - Ready in 15 Minutes
Ingredients
- 400g thin green beans, ends removed
- 1/2 small red onion, very thinly sliced
- 3 cans (about 420g) Italian or Spanish tuna in olive oil, drained lightly and oil reserved
- 4 medium ripe tomatoes, quartered
- 100g green olives, pitted or whole
- 150g mixed salad leaves (about 4 generous handfuls)
- Juice of 1 lemon
- 3 tbsp extra virgin olive oil for drizzling, plus a spoonful of the oil from the tuna cans
- Coarse sea salt
Instructions
- Get a medium pot of salted water boiling and set up a bowl of ice water next to the stove.
- Toss the green beans into the boiling water for just 30 seconds, then scoop them straight into the ice bath. Once they're cool, drain them well and pat them dry with paper towels so there's no water left clinging to them.
- Pile the salad leaves onto each plate. Scatter over the beans, onion, tomatoes and olives, then top with about a quarter of the tuna per plate in big chunks, along with a little of the oil from the can.
- Squeeze the lemon over the top, drizzle on plenty of extra virgin olive oil, sprinkle with sea salt and dig in.
Excess water is the absolute enemy of a great salad dressing, so ensure those beans are bone-dry before plating!
Tuna & Green Bean Salad FAQs
Can I use tuna in water instead of olive oil?
You can, but the salad will taste noticeably leaner and drier. Oil-packed tuna is silkier and more flavourful, and the oil from the can doubles as part of the dressing. If you only have tuna in water, drain it well and add an extra tablespoon or two of good extra virgin olive oil when you dress the salad.
Do I really need to blanch the green beans?
Yes, it makes a big difference. A quick 30-second blanch takes the raw, grassy edge off the beans while keeping them crisp, and the ice bath locks in that bright green colour. Raw green beans can taste bitter and squeaky in a salad like this.
Can I add eggs and potatoes to make it a full Niçoise?
Absolutely. Add halved soft- or hard-boiled eggs and a handful of boiled baby potatoes, and maybe a few anchovies or capers, and you're most of the way to a classic Niçoise. This version simply skips them for a lighter, faster salad made from what's in the cupboard.
Can I make this salad ahead of time?
You can prep the components ahead: blanch and dry the beans, slice the onion and quarter the tomatoes, and keep everything in separate containers in the fridge for up to a day. Assemble, dress and add the tuna just before serving so the leaves stay crisp and don't turn soggy.
How long do leftovers keep?
Dressed leftovers are best eaten within a day, kept covered in the fridge, though the leaves will soften. If you expect leftovers, store the undressed salad in an airtight container for up to 2 days and dress each portion as you serve it.
What can I serve with this tuna salad?
Crusty bread is perfect for mopping up the lemony, tuna-flavoured olive oil. For a heartier meal, serve it with boiled baby potatoes or a scoop of white beans on the side.
Pro Tips
- The Acid Balance: If your salad feels a bit heavy from the tuna oil, don't reach for more salt - add an extra squeeze of fresh lemon juice or a splash of apple cider vinegar. Acid cuts right through rich fats and brings all the produce back to life.
- Make it Vegan: To make this dish completely plant-based while retaining high protein, swap the canned tuna 1:1 with cooked, drained white cannellini beans or chickpeas tossed in a tablespoon of quality extra virgin olive oil and a pinch of dulse flakes.
- Temperature Matters: Never serve this salad ice-cold straight from the fridge! Let the blanched beans and canned tuna sit at room temperature for 15-20 minutes before serving so the olive oil un-solidifies and the aromatic flavors bloom fully.
