Wholesome Ingredients for This Tuna Nicoise Salad

To create the best Tuna Nicoise salad dressing and overall dish, we rely on high-quality, nutrient-dense ingredients. Here’s a closer look at what makes it shine:

Fresh tuna or light tuna pouches: For convenience, we recommend light tuna in water. It’s lean, high in protein, and low in calories. If you prefer premium flavor, canned or fresh grilled tuna steaks work beautifully.
Red potatoes: These provide a perfectly soft texture and are a potassium-rich carbohydrate source. For a lower-carb option, you can swap with steamed cauliflower or roasted radishes.
Green beans: Crisp-tender green beans add crunch and a dose of vitamin K. Blanching them maintains their vibrant color and nutrients.
Oil and vinegar dressing: A vinaigrette ties everything together with tangy brightness. Use bottled dressing for speed, or whisk up a simple homemade version with olive oil, red wine vinegar, Dijon mustard, and garlic.

Tuna Nicoise Salad Ingredients

1 pound red potatoes (about 2 large), cubed
1/4 pound fresh green beans, trimmed
1/2 cup oil and vinegar salad dressing
1/2 teaspoon grated lemon zest
1/4 teaspoon freshly ground black pepper
6 cups torn romaine lettuce
4 hard-boiled large eggs, sliced
3 pouches (2-1/2 ounces each) light tuna in water
2 medium tomatoes, chopped

Step-by-Step Tuna Nicoise Salad Instructions

Place the cubed potatoes in a large saucepan and add enough water to cover. Bring to a boil over medium heat. Reduce to a simmer and cook uncovered for 8-10 minutes, adding the green beans during the last 3 minutes of cooking time.
Drain the potatoes and green beans and immediately transfer them to a bowl of ice water to cool. Drain again and pat dry with a clean towel.
In a small bowl, whisk together the oil and vinegar salad dressing, grated lemon zest, and freshly ground black pepper.
Divide the romaine lettuce evenly among 4 serving plates. Arrange the potatoes, green beans, hard-boiled eggs, tuna pouches, and chopped tomatoes on top of the lettuce.
Serve the salad with the lemon-zest dressing drizzled over each plate, and enjoy immediately!

How to Customize This Tuna Nicoise Salad for Your Diet

Low carb or keto: Replace red potatoes with radishes or steamed cauliflower for a lower-carb alternative.
Vegan version: Swap out tuna and eggs for chickpeas or white beans, and use a Dijon vinaigrette made with agave syrup.
Higher protein: Add sliced grilled chicken or shrimp for a protein boost without altering the taste profile.
Nut-free: This recipe is naturally nut-free, but double-check all store-bought components like dressing to ensure no cross-contamination.

Our Team’s Tips for the Best Tuna Nicoise Salad

Don’t overcook the green beans—they should be bright green and lightly crisp for the best texture.
Chill your potatoes and beans in an ice bath after cooking to lock in their flavor and color.
If you’re using canned tuna, opt for solid white albacore for a firmer texture and milder flavor.
Batch prep the components: Boil and chill your veggies, and store them in the fridge for up to 3 days for quick assembly.
Store any leftover salad in an airtight container and enjoy within 1-2 days for the freshest taste.
