Salade Niçoise: How Should the Eggs Be Cooked?

Salade niçoise is a salad from Nice, France, commonly made with tomatoes, olives, anchovies, and other seasonal ingredients; versions vary, and some include green beans, potatoes, and tuna. For this hearty version, cook the eggs until both yolk and white are firm, then halve them and arrange them over the salad with a tangy mustard vinaigrette.

Ingredients

4 large eggs (about 200 g in shells)
12 oz (340 g) small waxy potatoes, such as fingerlings or baby potatoes
8 oz (225 g) green beans, trimmed
1 pint (300 g) cherry tomatoes, halved, or 3 medium tomatoes (about 450 g), cut into wedges
1 small cucumber (about 200 g), sliced
1 small red onion (about 75 g), thinly sliced
5 oz (140 g) mixed salad leaves or tender lettuce
1 can tuna, drained, 5 oz (142 g), preferably packed in olive oil
12 Niçoise or Kalamata olives (about 30 g), pitted if desired
4 anchovy fillets (about 15 g), drained, optional
2 tbsp (30 ml) extra-virgin olive oil
1 tbsp (15 ml) red wine vinegar
1 tsp (5 g) Dijon mustard
1 small garlic clove (about 3 g), finely grated or minced
¼ tsp (1.5 g) fine salt, plus more for cooking water
⅛ tsp (0.3 g) freshly ground black pepper
1 tbsp (15 ml) cold water, as needed to loosen the dressing

Instructions

Boil the eggs until firm. Put the eggs in a saucepan in a single layer and cover with cold water by about 1 inch (2.5 cm). Bring to a steady boil over medium-high heat. Cover the pan, remove it from the heat, and let the eggs stand for 12 minutes. Transfer them to a bowl of ice water for 5 minutes, then peel and halve. The yolks and whites should be firm; that is the recommended doneness for whole boiled eggs. Refrigerate the eggs if you are not assembling the salad promptly.
Cook the potatoes. While the eggs stand, put the potatoes in a separate saucepan and cover with cold water by about 1 inch (2.5 cm). Add a generous pinch of salt. Bring to a boil, then simmer for 12–15 minutes, until a knife slides easily into the largest potato. Drain and let cool until easy to handle, then halve or cut into bite-size pieces.
Blanch the beans. Bring a saucepan of salted water to a boil. Add the green beans and cook for 3–4 minutes, until bright green and just tender. Drain and rinse under cold running water, or plunge into a bowl of ice water, to stop the cooking. Drain thoroughly and pat dry.
Make the dressing. Whisk the olive oil, vinegar, mustard, garlic, salt, and pepper in a small bowl. Whisk in the cold water a little at a time if the dressing is too sharp or thick. Taste and adjust the seasoning; olives and anchovies are salty, so keep the dressing balanced rather than oversalting it.
Arrange the salad. Spread the leaves across a large platter or divide them among four plates. Arrange the potatoes, green beans, tomatoes, cucumber, and onion over the leaves. Break the tuna into generous pieces and add it with the olives and anchovies, if using. Place the egg halves on top, spoon the dressing over everything, and serve promptly.

Tips

Start eggs in cold water. This method and the 12-minute covered rest give firm whites and yolks without keeping the pan at a rolling boil, which can make shells crack and eggs tough.
Cool and dry the vegetables. Warm potatoes can wilt lettuce, while wet beans dilute the dressing. Let the potatoes cool and drain the beans well before assembly.
Choose a practical olive substitute. Small Niçoise olives can be difficult to find. Kalamata olives are a convenient option, though they are larger and fruitier; slice them or use fewer if you prefer a milder flavor.
Keep components separate for make-ahead preparation. Cook the eggs, potatoes, and beans ahead, but store them separately and dress the salad just before serving so the leaves stay crisp.

Serving Suggestions

Serve the salad as a substantial lunch or a light dinner, with crusty bread to catch the vinaigrette. It also works well as part of a larger meal alongside a simple vegetable soup or grilled vegetables. For a composed presentation, keep the ingredients in distinct sections instead of tossing them together; this makes it easy for guests to choose how much tuna, anchovy, or egg they want.

Variations

For a version without fish, omit both tuna and anchovies and add extra olives, sliced radishes, or cooked artichoke hearts. You can leave out the potatoes or green beans for a lighter, more produce-forward salad, or use canned tuna in water if you prefer a less rich result. Some traditional and family versions differ in their ingredients, so treat this as one satisfying interpretation rather than a fixed formula. If anchovies are hard to find or too assertive, simply omit them; the dressing and olives still provide plenty of savory flavor.

Storage and Reheating

For food safety, refrigerate cooked eggs, potatoes, and beans within 2 hours of cooking; keep the refrigerator at 40°F (4°C) or below. Store the cooked components in covered containers, separately from the lettuce, cut tomatoes, and dressing. Properly refrigerated cooked eggs and vegetables are generally best used within 3–4 days, though the assembled salad is best eaten the day it is dressed. Keep canned tuna refrigerated after opening and use it within 3–4 days. Do not leave the finished salad at room temperature for more than 2 hours, or more than 1 hour when the temperature is above 90°F (32°C). This salad is served cold, so reheating is not needed; discard leftovers that have been left out beyond those limits.

Frequently Asked Questions

How must the eggs be cooked for salade niçoise?
Cook them until both the white and yolk are firm. In this recipe, the eggs stand off the heat, covered, for 12 minutes after the water reaches a boil, then cool in ice water. This makes them easy to peel and neat to halve for serving.

Can I make the eggs ahead?
Yes. Cool them promptly in ice water, refrigerate them in their shells in a covered container, and peel shortly before assembling if you want the cleanest-looking halves. Use refrigerated hard-cooked eggs within 3–4 days.

Can the eggs be soft-boiled?
You can choose a softer yolk if you prefer, but it is not the method used here: the recipe calls for firm yolks and whites so the egg halves hold their shape on the platter. For guests who need eggs thoroughly cooked, serve the firm-cooked version.

Is tuna essential?
No. Tuna is common in many versions, but salade niçoise has regional and household variations. Omit it for a vegetable-focused salad, or replace it with extra olives or artichoke hearts.

Can I dress the salad in advance?
It is better to keep the dressing separate until just before serving. Dressing draws moisture from the vegetables and softens the leaves, especially after refrigeration. The vinaigrette can be mixed a day ahead and kept covered in the refrigerator; whisk it again before using.
