La Salade Niçoise: A Classic French Tuna Salad

La salade niçoise is a French salad associated with Nice, built around tomatoes, olives, anchovies and a sharp olive-oil dressing. This substantial version adds seared tuna, potatoes, green beans and eggs; regional and family versions vary, and the components are arranged rather than tossed so each one keeps its character.

Ingredients

12 oz (340 g) small waxy potatoes, such as fingerlings or baby Yukon Golds
8 oz (225 g) green beans, trimmed
4 large eggs
12 oz (340 g) sushi-grade or otherwise high-quality tuna steaks, about 1 inch (2.5 cm) thick
1 tbsp (15 ml) olive oil, for the tuna
½ tsp (3 g) fine salt, plus more for the cooking water
¼ tsp (1 g) freshly ground black pepper
2 tbsp (30 ml) red wine vinegar
1 tsp (5 ml) Dijon mustard
5 tbsp (75 ml) extra-virgin olive oil, for the dressing
1 small garlic clove, finely grated or minced
½ tsp (1 g) dried herbes de Provence, or 1 tsp (1 g) chopped fresh thyme
1 pint (300 g) ripe cherry tomatoes, halved
½ small red onion (about 2 oz/55 g), thinly sliced
½ cup (75 g) Niçoise olives, pitted or whole
4 anchovy fillets (about 15 g), drained, plus extra to taste
4 cups (120 g) tender lettuce leaves, such as butter lettuce
2 tbsp (8 g) chopped flat-leaf parsley, optional

Instructions

Cook the potatoes. Put the potatoes in a saucepan and cover with cold water by about 1 inch (2.5 cm). Salt the water, bring it to a boil, then simmer for 12–18 minutes, depending on their size, until a knife slides in easily. Drain and let cool until comfortable to handle. Halve or quarter them, then season lightly with salt and pepper.
Cook the eggs and beans. Bring a second saucepan of water to a boil. Lower in the eggs and boil for 9 minutes for firm, slightly creamy yolks; the yolk and white should be firm for safely cooked whole eggs. Transfer them to cold water. Add the green beans to boiling salted water and cook for 3–4 minutes, until bright green and crisp-tender. Drain and rinse briefly under cold water to stop the cooking. Peel and halve the cooled eggs.
Make the dressing. Whisk the vinegar, mustard, garlic, herbes de Provence and a pinch of salt in a small bowl. Slowly whisk in the 5 tablespoons olive oil until blended. Taste and adjust the salt and pepper. The anchovies and olives add salt later, so season gently.
Sear the tuna. Pat the tuna dry and season both sides with the ½ teaspoon salt and ¼ teaspoon pepper. Heat 1 tablespoon olive oil in a heavy skillet over high heat. Sear the tuna for about 1–2 minutes per side for a browned exterior and rare center, adjusting for thickness. A rare-seared center is not cooked to the USDA FSIS safe minimum internal temperature of 145°F (63°C) for fish; for a fully cooked, food-safe serving, use a thermometer and cook the thickest part to 145°F (63°C). Rest the tuna for 3 minutes, then slice across the grain. For anyone who is pregnant, very young, older, or immunocompromised, serve tuna cooked to 145°F (63°C), not rare.
Arrange the salad. Spread the lettuce over a large platter. Arrange the potatoes, green beans, tomatoes, onion, olives and egg halves in separate groups on top. Add the sliced tuna and anchovy fillets. Drizzle with dressing, scatter with parsley if using, and serve promptly. Pass any remaining dressing at the table.

Tips

Choose small waxy potatoes: they hold their shape better than floury baking potatoes. Start them in cold water so they cook evenly from edge to center.
To make the green beans ahead without losing their color, cool them promptly after boiling and dry them well. Excess water dilutes the dressing.
Niçoise olives are small, firm and briny. If they are unavailable, use Kalamata olives; they are softer and fruitier, so the result will taste less like the classic salad.
For easier eating, pit olives before serving and warn guests if you leave the pits in. Keep the dressing lightly seasoned until the anchovies and olives are on the platter.

Serving Suggestions

Serve the salad as a complete lunch or a light dinner with crusty bread to catch the dressing. A chilled dry rosé or sparkling water with lemon works well alongside it. For a more leisurely meal, bring the platter to the table with extra dressing, anchovies and olives so each person can adjust their portion.

Variations

For a pantry-friendly version, replace the seared tuna with 1 can (5 oz/142 g) drained tuna, preferably packed in olive oil; it is ready to eat, so skip the searing step. Canned tuna makes the salad less delicate but convenient. Some versions omit potatoes or green beans, while others add cucumber, radishes or capers. These are reasonable variations, though the exact ingredients differ across cooks and regions. If anchovies are not to your taste, leave them out and add a few extra olives; the dressing will be less deeply savory.

Storage and Reheating

For best texture, serve the assembled salad soon after dressing it. Refrigerate leftovers within 2 hours, preferably with dressing kept separate, in a covered container at 40°F (4°C) or below. The components are best within 1–2 days; cooked potatoes, beans and eggs can generally be refrigerated for 3–4 days, but dressed lettuce and seared tuna lose quality sooner. Do not leave the salad at room temperature for more than 2 hours, or more than 1 hour if the temperature is above 90°F (32°C). Do not reheat the assembled salad; serve chilled or at cool room temperature. If reheating any cooked leftovers separately, bring them to 165°F (74°C), though this will change the tuna and vegetables.

Frequently Asked Questions

Can I make salade niçoise ahead?
Yes. Cook and chill the potatoes, beans and eggs up to a day ahead, and mix the dressing separately. Keep the lettuce, tomatoes and sliced onion refrigerated, then sear and slice the tuna and assemble shortly before serving.

Can I use canned tuna instead of fresh?
Yes. Drain a 5-ounce (142 g) can and flake it over the salad in place of the seared tuna. Oil-packed tuna adds richness; water-packed tuna gives a lighter result. Since it is already cooked, it does not need searing.

How do I know when the potatoes are done?
Test the largest one with a thin knife or skewer. It should pass through the center without resistance, while the potato still holds its shape. Check early and drain promptly to prevent waterlogged or breaking potatoes.

Is rare tuna safe to eat?
Rare tuna does not meet the USDA FSIS safe minimum of 145°F (63°C) for fish. If you choose to serve it rare, understand that it carries more food-safety risk; cook it to 145°F (63°C) for a fully cooked serving. Pregnant people, young children, older adults and people with weakened immune systems should choose fully cooked tuna.

What can I use instead of Niçoise olives?
Kalamata olives are a practical substitute and are widely available. They tend to be softer and more intensely fruity, so the salad will taste different from one made with the firmer, milder Niçoise olive.

Should the salad be tossed?
It is usually arranged in groups on a platter, which keeps the ingredients distinct and makes the presentation easy to serve. You can toss it gently in a large bowl if you prefer, but add the dressing gradually so the leaves do not become soggy.
