This salade Niçoise is based on my YouTube video, with a few adjustments since publication so the recipe is easier to reproduce at home. In the video, the salad is made in a generous, colorful style with fresh tuna, potatoes, eggs, anchovies, olives, tomatoes, peppers and green beans. For the written version, I tightened the vinaigrette, adjusted the lemon and oil balance, and made the amounts more precise so the salad tastes bright without becoming too sharp or watery.

A salade Niçoise is a French composed salad from the south of France, usually built around tomatoes, eggs, olives, anchovies, tuna and seasonal vegetables. This version is my way of making it: more generous, with tender potatoes and quickly seared fresh tuna instead of only canned tuna. It is the kind of salad I make when I want a real meal, not just a side salad, especially in summer, but it still works year-round if you use good tomatoes and crisp green beans.

I make it this way because the contrast matters. The potatoes make the salad satisfying, the green beans give it snap, the tomatoes bring juice, and the tuna goes on warm at the end so it feels more like a proper bistro-style dinner. The mistake to avoid is drowning everything in too much lemon vinaigrette too early. Tomatoes, cooked beans and warm potatoes all release moisture, so the dressing has to be bold but controlled.

Why This Version Works

The original video has the right idea: lots of fresh vegetables, a sharp lemon dressing, olives, anchovies, hard-boiled eggs and tuna seared quickly in olive oil. The part that needs precision for a website recipe is the vinaigrette. Around 1/2 cup lemon juice with too little oil can become aggressive, especially with anchovies and olives already bringing salt. A better ratio is closer to 1 part lemon juice to 2 parts olive oil, with basil to soften the acidity.

What I look for here is a salad that tastes fresh, not sour. When the vinaigrette is right, it should smell like lemon and basil first, then olive oil. It should coat a spoon lightly, not sit like straight juice at the bottom of the bowl.

The tuna is also important. Fresh tuna is lean, so it does not forgive overcooking. I prefer to cut it into large cubes and sear it fast in a hot pan. The outside should lose its raw shine and pick up a little color, but the middle should stay pink. You know it is ready when the cubes still feel slightly springy, not firm all the way through.

This is different from my easy tuna salad with eggs, which is colder, simpler and more of a quick lunch. It is also not a creamy tuna dish like creamy tuna pasta or a pasta salad like tuna pasta salad with basil vinaigrette. This one is fresher, more vegetable-forward, and built like a full composed salad with warm seared fish.

Ingredients You Need

The base is simple: tomatoes, small potatoes, green beans, bell peppers, red onion, olives, anchovies and eggs. The colors are not just for looks. Red, yellow, orange and green peppers give sweetness and crunch, while the tomatoes bring the soft juicy part of the salad.

For the potatoes, use small waxy potatoes if possible. Baby red, yellow or mixed-color potatoes work well because they hold their shape after boiling. Russet potatoes are not ideal here because they can break apart and make the salad look heavy.

For the tuna, choose a fresh tuna steak thick enough to cube. If you are in Canada or the USA and buying tuna from a grocery store fish counter, ask for a piece suitable for searing. It does not need a long marinade. Salt, pepper and a quick hit of lemon pepper are enough.

The dressing is close to my 2-minute lemon vinaigrette, but with fresh basil added directly into the bowl. If you want a more classic all-purpose dressing, my classic vinaigrette is a good base to understand the oil and acid balance.

Step-by-Step Instructions

Start with the potatoes because they take the longest. Put them in salted water and simmer until a knife slides in easily, about 20 to 25 minutes depending on size. Do not boil them violently. A hard boil can split the skins and make the edges crumble. Drain them, let them cool just enough to handle, then cut them into bite-size pieces.

the eggs in boiling water for 11 to 12 minutes. Cool them under cold water, peel them, and slice them into rounds or wedges. I prefer firm eggs here because the yolk holds up better on the platter.

Blanch the green beans in salted boiling water for about 4 minutes. They should turn brighter green and bend slightly while still keeping a little bite. Drain and rinse under cold water, or spread them on a tray to cool. The mistake to avoid is overcooking them until they go soft and dull. This salad needs texture.

Cut the peppers into thin strips. Slice the red onion thinly. Core the tomatoes and cut them into chunks instead of thin rounds. I prefer chunks because they mix better with the vinaigrette and release little pockets of juice into the salad. At this point, the bowl should look colorful and uneven in a good way, not like everything was cut with a ruler.

Make the vinaigrette with lemon juice, olive oil, basil, salt and pepper. Taste it before adding it to the vegetables. It should be bright, but not harsh. Add about two-thirds of it to the vegetables and potatoes, then toss gently. Keep the rest for finishing.

Arrange the salad on a large platter. Add the olives, anchovies and sliced eggs on top instead of mixing them too much. This keeps the eggs clean and lets people get a little anchovy or olive when they want it.

Now cook the tuna. Heat a skillet over medium-high heat and add a thin layer of olive oil. When the oil moves easily in the pan and looks glossy, add the tuna cubes. They should sizzle as soon as they touch the pan. Season with lemon pepper and cook quickly, turning the pieces so the outside sears but the center stays pink.

At the end, turn off the heat and add a spoonful or two of vinaigrette to the hot pan. It will loosen the browned bits and make a quick warm dressing. This is the same idea as learning how to deglaze a pan, but done very lightly so the lemon and oil pick up the tuna juices without reducing into something heavy.

Spoon the warm tuna over the salad and finish with the remaining vinaigrette.

How to Serve It

This salad can be served as a main dish for lunch or dinner. It has protein from the tuna and eggs, vegetables for freshness, and potatoes to make it filling without needing bread or pasta. It is lighter than a creamy pasta dinner, but it still feels complete.

If you want something extra on the table, keep it simple. A few pieces of fresh tomato bruschetta work well when tomatoes are in season. For a more classic French-style meal, you could add homemade garlic croutons or a side of crispy homemade French fries if you want something more bistro. For a lighter summer spread, serve it near a homemade Greek salad, but keep the dressings separate so the flavors do not all run together.

Substitutions

Fresh tuna can be replaced with good canned tuna packed in olive oil. Drain it lightly and flake it over the salad at the end. It will be more traditional in feel and easier for a quick lunch.

Anchovies can be reduced or left on the side if some people do not like them. I would not remove the olives at the same time, though, because the salad needs that salty Mediterranean bite.

Basil can be replaced with parsley, but basil gives a warmer, sweeter smell with the lemon. Dill is not my first choice here because it pushes the salad in a different direction.

Green beans can be replaced with asparagus in spring or blanched snap peas in a pinch. Keep the cooking short so the vegetables stay crisp.

If you do not have lemon pepper, use black pepper and a little lemon zest. That gives a cleaner flavor than adding more lemon juice.

For a more seafood-focused meal, this salad sits nicely beside recipes like pan-seared salmon or sole meunière with lemon butter, but keep the portions smaller because the salad already has tuna and eggs.

FAQ

Can I make this salad ahead of time?

Yes, but do it in parts. Cook the potatoes, eggs and green beans ahead, then keep them chilled. Cut the tomatoes and dress the salad closer to serving so it does not become watery. Sear the tuna right before serving if you want the best texture.

Should salade Niçoise have potatoes?

Classic versions can be debated, and some are stricter than others. This is my version from the video, and I use potatoes because they make the salad more generous and practical as a full meal. The key is using waxy potatoes that hold their shape.

Can I use canned tuna?

Yes. Canned tuna in olive oil works very well. Use about two cans, drained, for 4 portions. Do not cook it. Just add it over the top with the eggs, olives and anchovies.

Why is my salad watery?

Usually the tomatoes were too juicy, the beans were not drained well, or too much vinaigrette was added too early. Salt also pulls moisture from vegetables. I prefer to dress lightly first, then finish with more vinaigrette on the platter.

How do I keep the tuna from drying out?

Use a hot pan and cook it quickly. The cubes only need a short sear on the outside. If the tuna turns pale all the way through and feels firm, it has gone too far.

What makes this different from other salad recipes?

This is a composed French-style salad with warm seared tuna, eggs, anchovies, olives and potatoes. It is not creamy like a macaroni salad, not pasta-based like an orzo pasta salad, and not avocado-based like a spicy avocado tuna salad. The flavor is lemony, briny and fresh, with the tuna cooked at the last minute.
