- 1/4 cup fresh parsley, chopped
For the Lemon-Dijon Dressing

- 1 tablespoon extra virgin olive oil
- 1 tablespoon fresh lemon juice
- 1 teaspoon Dijon mustard
- 1/2 teaspoon dried oregano

Step-by-Step Instructions
-
Step 1: Prepare the Hard-Boiled Eggs and Green Beans
Start by boiling your eggs. Place eggs in a small pot, cover with cold water, and bring to a rolling boil. Remove from heat, cover, and let sit for 9-12 minutes for firm yolks. Drain, cool under cold water, peel, and chop. At the same time, blanch your green beans. Bring a small pot of salted water to a boil, add green beans, and cook for 2-3 minutes until bright green and tender-crisp. Immediately transfer to an ice bath to stop cooking, then drain and chop.
Small tip: For perfectly peelable eggs, add a teaspoon of baking soda to the boiling water.
-
Step 2: Make the Lemon-Dijon Dressing
In a medium bowl, whisk together the mayonnaise, extra virgin olive oil, fresh lemon juice, Dijon mustard, dried oregano, black pepper, and sea salt. Whisk until the dressing is smooth and well combined. Taste and adjust seasoning if needed. This dressing brings all the Niçoise flavors together.
Small tip: Use fresh lemon juice for the best, brightest flavor; bottled juice often lacks the same zing.
-
Step 3: Combine the Niçoise Tuna Salad Ingredients
Add the drained and flaked tuna to the bowl with the dressing. Gently fold it in. Then, add the chopped hard-boiled eggs, green beans, halved cherry tomatoes, chopped Kalamata olives, red onion, capers, and fresh parsley. Fold everything together carefully until all ingredients are evenly coated. Try not to mash the tuna too much.
Small tip: Be gentle when mixing to keep the texture of the tuna and eggs intact, creating a more appealing salad.
-
Step 4: Prepare the Bread
Lightly toast your bread slices, if desired. This adds a nice crunch and prevents the sandwich from getting soggy. You can also lightly brush the inside of the bread with a little extra virgin olive oil for added flavor, especially if using a rustic artisan bread.
Small tip: If using a very crusty bread, you might want to scoop out a little of the soft interior to make more room for the generous filling.
-
Step 5: Assemble Your Tuna Niçoise Sandwiches
Place a lettuce leaf or a handful of mixed greens on one slice of bread for each sandwich. This creates a barrier and adds a lovely fresh crunch. Spoon a generous amount of the Niçoise tuna salad mixture onto the lettuce. Spread it evenly to the edges. Top with the second slice of bread.
Small tip: Don’t be shy with the filling! These sandwiches are meant to be hearty and packed with flavor.
-
Step 6: Serve and Enjoy!
Carefully slice each sandwich in half, if you wish, and serve immediately. These sandwiches are fantastic on their own or paired with a simple side. Get ready to savor every single bite of this incredible flavor combination!
Small tip: If making ahead, store the tuna salad separately and assemble just before serving to keep the bread from getting soggy.
Tips & Variations
- Gluten-Free Option: Easily make this recipe gluten-free by serving the Tuna Niçoise salad on your favorite gluten-free bread, in a lettuce wrap, or even as a standalone salad over a bed of mixed greens.
- Vegan/Vegetarian Option: Replace the tuna with mashed chickpeas or white beans for a creamy base. Omit the hard-boiled eggs. Add extra capers, olives, and a sprinkle of nutritional yeast for an umami boost. Use a vegan mayonnaise for the dressing.
- More Vegetables or Protein: Feel free to add thinly sliced cucumber, bell peppers, or even a handful of baby spinach to the salad mixture. For extra protein, consider adding a few chopped anchovies (classic Niçoise!) or crumbled feta cheese.
- Spicy Version: To give your sandwich a kick, add a pinch of red pepper flakes to the dressing or a dash of hot sauce. You could also finely chop a jalapeño and mix it into the salad.
- Flavor Boost: For an even deeper flavor, lightly smash a clove of garlic and let it infuse in the olive oil for 10 minutes before making the dressing, then remove. A sprinkle of fresh thyme or basil can also add an aromatic touch.

Storage Tips
The prepared Tuna Niçoise salad mixture can be stored in an airtight container in the refrigerator for up to 3 days.
