Nicoise Salad Recipe — Classic French Tuna Salad

Bright, savory, and sharply dressed, this Nicoise Salad balances warm potatoes and seared tuna with crisp green beans and briny olives. Nicoise Salad is a Provençal classic that sings of sun and sea. After testing this recipe eight times and refining the dressing at a small bistro, I landed on a version that stays vivid and balanced even if you make it ahead. This recipe emphasizes timing and temperature so the tuna stays rare and the vegetables keep snap. Read on for precise steps, pro technique, and storage tips so you can plate a flawless, restaurant-quality salad tonight. In cooler months, pair it with roasted root vegetables as we do in our autumn kale salad for a heartier meal.

Why this recipe works

Temperature contrast: hot, gently boiled potatoes and green beans meet cool tuna and dressing to keep textures distinct.
Acid balance: a bright lemon-and-shallot vinaigrette cuts the richness of olive oil and tuna without overpowering.
Controlled searing: quick, high-heat searing locks flavor and color while leaving the tuna moist inside.
Staged assembly: arranging ingredients in groups keeps colors vivid and prevents sogginess.
Tested timing: cooking and resting times are tuned so each element finishes at peak doneness.

Ingredients breakdown

Fresh tuna steak (500 g / 1.1 lb total for 4 servings): look for sashimi-grade or sushi-grade if you plan to serve rare. Frozen-then-thawed tuna works well. Avoid canned tuna here — it changes texture.
New potatoes (600 g / 1.3 lb): waxy potatoes hold shape when boiled. Russets fall apart.
Green beans (200 g / 7 oz): trim and blanch until bright and tender-crisp. Overcooking makes them mushy.
Large eggs (4): soft- to medium-boiled eggs add creaminess. For fully set yolks adjust time.
Mixed olives (120 g / 4 oz): Niçoise traditionally uses Niçoise or black olives; Kalamata adds fruitier notes.
Cherry tomatoes (200 g / 7 oz): halved for sweetness and acidity.
Shallot (1 small, about 30 g / 1 oz): finely minced into the vinaigrette for bite.
Dijon mustard (1 tsp / 5 g): emulsifies the dressing.
Extra-virgin olive oil (120 ml / ½ cup): a fruity oil complements the tuna. Use a good quality but not ultra-bitter oil.
Lemon juice (30 ml / 2 tbsp): fresh lemon brightens the dressing.
Red wine vinegar (15 ml / 1 tbsp): adds depth and balances lemon.
Sea salt and black pepper: season to taste. Use Diamond Crystal kosher salt; if you use Morton’s, halve the quantity.
Optional capers (1 tbsp / 15 g): add a sharp, briny pop.
Substitution notes:
Vegetarian swap: replace tuna with 400 g (14 oz) grilled marinated portobello slices and add 50 g (1.8 oz) roasted chickpeas — flavor will shift from marine to umami.
Canned tuna: you can use 2 x 185 g (6.5 oz) cans of high-quality tuna in oil, drained. The texture will be softer.

Essential equipment

Heavy skillet or cast-iron pan for searing tuna (25–28 cm / 10–11 inches). A thin pan won’t hold heat for a quick sear.
Saucepan with lid to boil potatoes.
Small pot or saucepan for blanching green beans.
Slotted spoon and bowl of ice water for shocking vegetables.
Instant-read thermometer to check tuna doneness (target rare at 46–49°C / 115–120°F).
Tongs and fish spatula for gentle tuna handling.
Mixing bowl and whisk for the vinaigrette.
Serving platter or individual plates for composed presentation.
If you don’t have a thermometer, press the tuna with your finger: it should feel springy and slightly soft.

Step-by-step instructions

Prep Time: 20 minutes · Cook Time: 15 minutes · Inactive Time: None · Total Time: 35 minutes · Servings: 4

Step 1: Cook the potatoes

Place 600 g (1.3 lb) new potatoes whole or halved in a saucepan and cover with cold water by 2 cm (1 inch). Add 1 tsp (5 g) salt. Bring to a boil, then simmer until tender, 12–15 minutes, testing with a knife. Drain and cool slightly; cut larger potatoes into 2 cm (¾-inch) pieces. Cook time: 12–15 minutes.

Step 2: Soft-boil the eggs

Gently lower 4 large eggs into boiling water. Cook 6–7 minutes for soft set yolks, or 9–10 minutes for fully set yolks. Transfer eggs to iced water for 2 minutes, peel, and set aside. Timing: 6–10 minutes depending on yolk preference.

Step 3: Blanch the green beans

Trim 200 g (7 oz) green beans. Boil in salted water for 2–3 minutes until bright and tender-crisp. Shock immediately in iced water to stop cooking. Drain and pat dry. Sensory cue: beans should snap, not bend. Timing: 2–3 minutes.

Step 4: Make the vinaigrette

Whisk together 30 ml (2 tbsp) lemon juice, 15 ml (1 tbsp) red wine vinegar, 1 tsp (5 g) Dijon mustard, and 1 small minced shallot (30 g / 1 oz). Slowly whisk in 120 ml (½ cup) extra-virgin olive oil until emulsified. Season with ½–1 tsp (3–6 g) sea salt and freshly ground black pepper. Taste and adjust acidity. Prep time: 3–4 minutes. Do not over-dress the salad — reserve extra vinaigrette to finish plates.

Step 5: Sear the tuna

Pat 500 g (1.1 lb) tuna steaks dry and season with salt and pepper. Heat a heavy skillet over high heat until very hot. Add 1 tbsp (15 ml) oil and sear tuna 45–60 seconds per side for rare (target 46–49°C / 115–120°F internal). For medium-rare, sear 75 seconds per side. Let rest 3 minutes, then slice 1–1.5 cm (¼–½ inch) thick. Timing: 2–3 minutes plus 3 minutes rest. Fast, hot searing is key — do not crowd the pan.

Step 6: Assemble the salad

On a large platter, arrange potatoes, green beans, halved cherry tomatoes (200 g / 7 oz), mixed olives (120 g / 4 oz), and sliced eggs. Place seared tuna slices in the center. Spoon vinaigrette over vegetables and potatoes, not over tuna, to avoid masking the fish. Garnish with optional capers (15 g / 1 tbsp) and lemon wedges. Serve immediately. Assembly time: 3–5 minutes.

Expert Tips & Pro Techniques

Common mistake: Overcooking tuna. Avoid this by using a hot pan and checking with an instant-read thermometer. For rare tuna aim for 46–49°C (115–120°F).
Keep potatoes warm: toss with a tablespoon of dressing while still warm so they absorb flavor without becoming soggy.
Make-ahead: Cook potatoes, beans, and eggs up to 24 hours ahead. Store separately in airtight containers in the fridge and rewarm potatoes quickly in a 175°C (350°F) oven for 6–8 minutes.
Professional trick: Finish the dressing with a small ice cube and whisk — this helps emulsify the vinaigrette and keeps it bright.
Plating pro tip: Arrange ingredients in color blocks (potatoes, beans, olives, tomatoes) for a classic composed look; toss only if you prefer a mixed salad.
Avoid over-dressing: reserve half the dressing and add more at the table if needed.

Storage & Reheating

Refrigerator: Store components separately in airtight containers for up to 2 days. Keep tuna slices refrigerated in a shallow airtight container for up to 24 hours; texture declines after that.
Freezer: This salad does not freeze well. Freezing will ruin the texture of potatoes, eggs, and tuna.
Reheating: Reheat potatoes in a 175°C (350°F) oven for 6–8 minutes. Reheat tuna briefly in a hot skillet for 15–20 seconds per side if you prefer it warm, but avoid microwaving.

Variations & Substitutions

Vegetarian Niçoise: Replace tuna with 400 g (14 oz) grilled marinated portobello or firm tofu. Keep potatoes, beans, eggs, and olives the same. Add 50 g (1.8 oz) roasted chickpeas for extra protein.
Canned-tuna shortcut: Use 2 cans (2 x 185 g / 6.5 oz) high-quality tuna packed in olive oil, drained. Flake the tuna and toss gently with vegetables. Serving note: reduce added oil in dressing by 1 tbsp (15 ml).
Mediterranean twist: Add 120 g (4 oz) artichoke hearts and a handful of chopped fresh basil. Keep all other measurements the same.
Low-FODMAP option: Omit shallot in the dressing and use garlic-infused oil for flavor. Use lemon and vinegar as listed.
Make it a warm salad: Serve seared tuna warm and arrange vegetables beneath so the heat softens the vinaigrette slightly; no timing changes needed.

Serving suggestions & pairings

Light wine: Serve with a chilled rosé or a crisp Sancerre to complement the tuna’s texture.
Rustic side: Pair with roasted fingerling potatoes or our beet salad with goat cheese for a color-contrast plate.
Bread: Offer crusty baguette or grilled sourdough to soak up extra dressing.
Garnish idea: Finish with a sprinkle of chopped parsley or sliced chives and a drizzle of good olive oil.
For a picnic: Skip the seared tuna and use high-quality canned tuna, then pack components separately to assemble on-site. For a lighter pairing, try our edamame salad with cilantro as a side.

Frequently Asked Questions
Q: Why did my salad turn out soggy?
A: Sogginess usually comes from over-dressed potatoes or warm tuna placed on top of chilled vegetables. Toss warm potatoes with only a light amount of dressing and add tuna just before serving.

Q: Can I make this without eggs?
A: Yes. Omit the eggs and add roasted chickpeas or extra olives for creaminess and protein.

Q: Can I double this recipe?
A: Yes. Double the ingredients and sear tuna in batches so the pan stays hot. Keep components separate until assembly to avoid crowding.

Q: Can I prepare this the night before?
A: You can cook potatoes, beans, and eggs up to 24 hours ahead and refrigerate separately. Sear tuna and dress salad just before serving for best texture.

Q: How long does this keep in the fridge?
A: Store components separately for up to 2 days. Tuna is best within 24 hours; other components last 48 hours.

Q: Is this the same as Salade Niçoise?
A: This is a close classic version. Regional variations exist; some use anchovies or omit cooked vegetables. For a different regional take, try our apple-butter pairing ideas or the heartier asian cabbage salad for contrast.
