Niçoise Salad with Seared Ahi Tuna
This classic Niçoise Salad looks like something you’d order at a French bistro — and honestly, it tastes like it too. Composed salads always sound fussy until you actually make one, and then you realize the whole thing comes together in under 45 minutes with a little parallel planning.
The star here is sushi-grade Ahi tuna, lightly seared and sliced. It’s a serious upgrade from the canned variety in traditional recipes. Arranged over a bed of greens with roasted green beans, tender fingerling potatoes, hard-boiled eggs, cherry tomatoes, and Niçoise olives, all finished with a bright, herby lemon dressing. It’s a full meal in one beautiful platter.

The secret to pulling this off without stress is simple: start the potatoes and green beans at the same time. By the time both are done, you’re ready to sear the tuna, and the whole thing comes together like you planned it (because you did).

Niçoise Salad with Seared Ahi Tuna
Ingredients
Method
- Place top oven rack in center position and pre-heat oven to 425°F. Line a large, rimmed baking sheet with parchment paper or a Silpat and set aside.
- Combine all dressing ingredients in a glass jar with a tight-fitting lid. Seal and shake vigorously until thoroughly combined. Set aside.
- Place the green beans on the prepared baking sheet and drizzle with ½ tablespoon olive oil. Season with salt and black pepper, toss to combine, and spread into a single layer without overcrowding. Set aside.
- Place the potatoes in a large saucepan and cover with water by about 2 inches. Generously salt the water and bring to a boil over high heat. Cook for 8–10 minutes, or until fork tender but not mushy. Drain and set aside to cool.
- When the oven is ready, place the baking sheet of green beans inside and roast for 5 minutes. Flip the beans and return to the oven for another 5–6 minutes, until crisp-tender. Remove and set aside.
- Heat a grill pan over medium-high heat and spray with non-stick cooking spray or brush with a high smoke point oil. Brush the tuna steak on all sides with the remaining 1 tablespoon olive oil and season lightly with salt and pepper.
- Place the tuna steak and lemon halves on the hot grill pan. Press down with a spatula for maximum grill marks, if desired. Sear for 2–3 minutes on the first side, then remove the lemon halves and flip the tuna.
- Sear the second side for another 2–3 minutes, then quickly sear each edge for 1 minute per side. Remove from heat and set aside.
- In a medium bowl, combine the lettuce and tomatoes. Drizzle with a small amount of dressing and toss to combine.
- Slice the cooled potatoes into bite-sized pieces and toss with a small amount of dressing. Lightly dress the green beans as well.
- To assemble: slice the seared tuna and arrange on a large serving platter. Fill in around it with the dressed lettuce, tomatoes, potatoes, and green beans. Add the sliced hard-boiled eggs, olives, and grilled lemon halves to complete the composition. Season lightly with additional salt and pepper if desired. Serve immediately with remaining dressing on the side. Enjoy!
Tips & Variations
The Tuna
- Sushi-grade Ahi is non-negotiable for this preparation — you want it seared on the outside and rare in the center
- Pat the tuna completely dry before searing for the best crust
- Don’t move it around in the pan; let it release naturally before flipping
- If you prefer fully cooked tuna, canned tuna packed in oil is the traditional Niçoise choice and works beautifully
The Dressing
- Anchovy paste sounds scary; it just adds a salty, savory depth that you won’t be able to put your finger on but absolutely cannot skip
- Make the dressing up to 3 days ahead and store in the fridge; shake before using
- Taste and adjust lemon before assembling — it should be bright and punchy
The Components
- Use leftovers! Niçoise is a composed salad by nature — leftover roasted potatoes, steamed green beans, or even grilled salmon all work
- Can’t find Niçoise olives? Kalamata or any good black olive works fine
- Add artichoke hearts, roasted red peppers, or capers if you have them
Make It Ahead
- Hard-boil eggs up to 5 days in advance
- Make the dressing up to 3 days ahead
- Boil potatoes and roast green beans earlier in the day; bring to room temp before serving
- Sear the tuna right before assembling
Serving Suggestions
- Serve on a large platter family-style for the full visual impact — this is a showstopper
- Pair with a cold glass of Provençal rosé if you want to go full French
- Crusty bread on the side for soaking up that dressing
- Works beautifully as a lunch or light dinner on a warm spring or summer evening
Storage
The assembled salad doesn’t store well — the greens will wilt and the tuna will lose its texture. Store components separately in the refrigerator:
- Dressing: Up to 3 days in a jar in the fridge
- Cooked potatoes and green beans: Up to 2 days
- Hard-boiled eggs: Up to 5 days unpeeled; 2 days peeled
- Seared tuna: Best eaten same day; if you must store it, up to 1 day refrigerated
Frequently Asked Questions
Q: Do I have to use sushi-grade tuna?
A: For a lightly seared, rare-center preparation, yes, sushi-grade is important for safety. If you prefer fully cooked tuna or want a more budget-friendly option, high-quality canned tuna packed in olive oil is the traditional Niçoise choice and tastes great.
Q: What if I can’t find Niçoise olives?
A: Any good black olive works. Kalamata are the easiest substitute. Just avoid the canned California black olives; they’re too mild for this salad.
Q: Can I make this ahead for a dinner party?
A: Absolutely. It’s actually ideal for entertaining. Prep all the components ahead, store separately, and assemble the platter right before serving. Sear the tuna last.
Q: What is anchovy paste and where do I find it?
A: It’s a smooth paste made from anchovies. You’ll find it in a small tube in the canned fish aisle. It adds a salty, savory umami depth to the dressing without tasting “fishy.” A little goes a long way.
Q: Can I use regular tuna instead of Ahi?
A: Yes. Yellowfin or even a nice piece of fresh albacore works. Just adjust sear time based on thickness.
Why This Recipe Works
Composing each element separately lets you control the dressing level on each component so nothing gets soggy or overdressed
Roasting the green beans instead of blanching them adds flavor and keeps them from turning waterlogged
Searing the lemon halves alongside the tuna caramelizes the juice, making the squeezed lemon over the finished platter noticeably more complex
Dressing the potatoes warm allows them to absorb more flavor than if dressed cold
Building it on a platter instead of tossing keeps everything distinct and makes for a stunning presentation
