Ingredients

For this classic Mediterranean Tuna Salad, you’ll need:

• 2 (5 oz) cans of solid white albacore tuna packed in olive oil, drained (reserve 1 tablespoon oil)
• 1 medium cucumber, seeded and diced (about 1 cup)
• 1 pint cherry tomatoes, halved (about 2 cups)
• 1 red bell pepper, diced (about 1 cup)
• ½ cup Kalamata olives, pitted and halved
• ¼ cup red onion, finely diced
• ¼ cup fresh parsley, chopped
• 3 tablespoons fresh mint, chopped
• 2 tablespoons capers, drained
• 3 tablespoons extra virgin olive oil
• 2 tablespoons fresh lemon juice
• 1 teaspoon lemon zest
• 1 garlic clove, minced
• 1 teaspoon dried oregano
• ½ cup crumbled feta cheese
• Salt and freshly ground black pepper to taste

Pro Tips

Mastering this Mediterranean Tuna Salad comes down to three key techniques that elevate it from good to exceptional:

First, choose the right tuna. Oil-packed tuna (especially in olive oil) provides significantly more flavor than water-packed varieties. The oil keeps the tuna moist and infuses it with richness. For the best texture, drain the oil but don’t rinse the tuna, and flake it gently with a fork rather than breaking it into tiny pieces—those larger flakes create a more satisfying bite.

Second, perfect your vegetable prep. For cucumber, always remove the seeds to prevent excess moisture from diluting your dressing. Dice vegetables into uniform, small pieces (about ¼-inch) so every bite contains a perfect mix of ingredients. For red onion, soak the diced pieces in cold water for 5-10 minutes before adding to reduce their sharpness while maintaining their crisp texture.

Finally, let the flavors meld. While the salad is delicious immediately after preparation, allowing it to rest for 30 minutes before serving creates a harmonious flavor profile as the lemon and herbs infuse throughout. Just reserve the feta to add right before serving to maintain its integrity.

Instructions

Step 1: Prepare the tuna
Drain the canned tuna, reserving about a tablespoon of the olive oil. Place the tuna in a large bowl and gently flake it with a fork, maintaining some texture rather than breaking it down completely. The goal is to have nice, meaty pieces that stand up to the other ingredients.

Step 2: Prep the vegetables
Add the diced cucumber, halved cherry tomatoes, diced red bell pepper, halved Kalamata olives, and diced red onion to the bowl with the tuna. The colorful vegetables not only add nutrition but create that signature Mediterranean rainbow in your Mediterranean Tuna Salad.

Step 3: Add herbs and capers
Sprinkle in the fresh chopped parsley, mint, and capers. These ingredients bring the authentic Mediterranean flavor profile to your salad. The herbs add brightness while the capers contribute little bursts of briny flavor that complement the tuna perfectly.

Step 4: Create the dressing
In a small bowl, whisk together the reserved tuna oil, extra virgin olive oil, fresh lemon juice, lemon zest, minced garlic, and dried oregano until well combined. Season with salt and freshly ground black pepper to taste, remembering that the olives, capers, and feta will add saltiness to the final dish.

Step 5: Combine and marinate
Pour the dressing over the tuna and vegetable mixture, then gently fold everything together using a large spoon or spatula. Be careful not to overmix, which could break down the tuna too much. Cover the bowl and let it sit in the refrigerator for at least 15 minutes (or up to a few hours) to allow the flavors to develop.

Step 6: Finish and serve
Just before serving, fold in the crumbled feta cheese and give the salad one final gentle toss. Taste and adjust the seasoning if necessary. Serve your Mediterranean Tuna Salad chilled, garnished with additional fresh herbs and a lemon wedge for an extra pop of color and flavor.

Variations

For a Greek-style Tuna Salad, enhance the Mediterranean theme by adding ¼ cup thinly sliced pepperoncini peppers and swapping the mint for 2 tablespoons of fresh dill. Serve it stuffed into pita pockets with a dollop of tzatziki sauce for an authentic Greek lunch experience.

Transform this into a heartier Mediterranean Tuna Pasta Salad by mixing in 2 cups of cooked and cooled short pasta like rotini or farfalle. Add an extra tablespoon of olive oil and lemon juice to ensure there’s enough dressing to coat the pasta. This makes an excellent make-ahead lunch or potluck contribution.

For those following special diets, create a Dairy-Free Mediterranean Tuna Salad by replacing the feta with diced avocado, which provides similar creaminess with heart-healthy fats. The avocado should be added just before serving to prevent browning. This simple swap maintains all the wonderful Mediterranean flavors while accommodating dairy allergies or vegan guests.

Storage and Serving

Your Mediterranean Tuna Salad will keep well in an airtight container in the refrigerator for up to 3 days. The flavors actually continue to develop overnight, making this an excellent make-ahead option. If storing longer than a day, add the feta cheese just before serving to maintain its texture and appearance.

For a stunning presentation, serve this vibrant salad in a shallow bowl lined with crisp romaine lettuce leaves or atop a bed of lightly dressed arugula for added peppery flavor. The contrast between the bright salad and deep green leaves creates an Instagram-worthy dish.

Create an elegant Mediterranean lunch board by pairing the tuna salad with warm pita bread, cucumber slices, hummus, and additional feta cheese. For a lighter option, hollow out tomatoes or avocado halves and fill them with the salad for an impressive appetizer or light lunch that’s as beautiful as it is delicious.

FAQs

Can I use water-packed tuna instead of oil-packed?
Yes, you can substitute water-packed tuna, but you’ll need to add an extra tablespoon of olive oil to compensate for the lost moisture and richness. Water-packed tuna creates a lighter version of Mediterranean Tuna Salad with slightly less flavor depth.

How can I make this salad more filling for a main dish?
Add a can of rinsed and drained chickpeas or white beans to increase protein and fiber content. Alternatively, serve it over cooked quinoa or farro for a hearty grain bowl that’s still true to Mediterranean flavors.

Is this recipe keto-friendly?
Yes, this Mediterranean Tuna Salad is naturally low in carbohydrates and suitable for keto diets. Just be mindful of the capers and tomatoes, which contain small amounts of carbs, if you’re strictly counting.

Can I prepare this salad in advance for a party?
Absolutely! Prepare everything up to 24 hours ahead, but keep the feta cheese separate until serving. The flavors actually improve with time as the ingredients marinate together in the refrigerator.

What’s the best substitute for Kalamata olives if I don’t have them?
Any Mediterranean olive variety works well, including Niçoise, Gaeta, or green Castelvetrano olives. In a pinch, standard black olives will work, though they provide less distinctive flavor to your Mediterranean Tuna Salad.
