Transport your taste buds to the sun-drenched French Riviera with this elegant Niçoise salad. Originating in the city of Nice, this dish is the epitome of European light dining, offering a sophisticated balance of protein, fresh vegetables, and briny accents. It is more than just a salad; it is a composed masterpiece that celebrates the simplicity of high-quality ingredients handled with care.

The secret to a truly spectacular Niçoise lies in the textures. We use tender baby potatoes, crisp-tender haricots verts, and buttery Niçoise olives, all anchored by a perfectly seared Ahi tuna steak. While many traditional versions use canned tuna, searing a fresh fillet adds a luxurious, modern touch that makes this meal feel like a special occasion, even on a busy weekday.

To finish the dish, a bright and zesty lemon-Dijon vinaigrette ties every element together, cutting through the richness of the tuna and the creaminess of the soft-boiled eggs. Whether you're hosting a garden lunch or simply treating yourself to a nutritious dinner, this salad is guaranteed to impress with its vibrant colors and bold, Mediterranean flavors.

This recipe is designed to be flexible; feel free to swap the tuna for grilled salmon or keep it traditional with high-quality oil-packed tuna if you prefer.

Ingredients

  • Ahi tuna steak:8 oz
  • Baby red potatoes:8 oz
  • Haricots verts (thin green beans):4 oz
  • Large eggs:2 pieces
  • Cherry tomatoes, halved:1 cup
  • Niçoise olives:1/4 cup
  • Mixed baby greens:4 cups
  • Extra virgin olive oil:4 tbsp
  • Fresh lemon juice:1 tbsp
  • Dijon mustard:1 tsp
  • Capers, drained:1 tbsp
  • Salt and black pepper:1 to taste

Instructions

  1. Place the baby potatoes in a pot of salted water. Bring to a boil and cook until tender, about 10-12 minutes. During the last 3 minutes of cooking, add the haricots verts to the same pot to blanch them.

  2. Drain the potatoes and beans, then immediately plunge the beans into an ice bath to stop the cooking and keep them bright green. Slice the potatoes in half once cooled.

  3. Boil the eggs in a separate small pot for 7 minutes for a slightly jammy yolk. Transfer to an ice bath, peel, and halve.

  4. Season the tuna steak generously with salt and pepper. Heat 1 tablespoon of olive oil in a skillet over high heat. Sear the tuna for about 1-2 minutes per side for rare/medium-rare. Remove from heat and slice into thick strips.

Tips & Notes

  • For the best flavor, use Niçoise olives, which are small, dark, and slightly nutty. Kalamata olives are a decent substitute if needed.
  • Ensure your skillet is very hot before adding the tuna to get a beautiful crust without overcooking the center.
  • You can prepare the potatoes, beans, and eggs up to a day in advance to make the final assembly even faster.
