Greek Tuna Salad

Deli tuna salad has a texture problem.

You know the one: a heavy scoop of mayo, a few sad bits of celery, and tuna mashed into paste.

I grew up on that version, and for years I thought that was just what tuna salad was.

Then I started spooning a Greek dressing over the tuna instead of reaching for the mayo jar.

Olive oil, lemon, red wine vinegar, a good shake of oregano.

Suddenly the tuna tasted bright instead of gluey.

I make this at least twice a month now, usually on a Sunday so I have lunches ready for the week.

My wife, who claims she hates tuna salad, will eat a bowl of this standing at the counter.

It comes together in about 15 minutes, and there's no cooking at all.

Just whisk the dressing, chop a few vegetables, and fold in the tuna and feta.

The feta and Kalamata olives do most of the heavy work here, and the cucumber keeps every bite cool and crisp.

Want a lunch that actually holds up in the fridge instead of weeping mayo by Wednesday? This is it.

I promise, once you taste tuna salad this way, the mayo version starts to feel like a downgrade.

Why You'll Love This Greek Tuna Salad

This is the lighter tuna salad you'll actually crave. It hits that fresh, briny, lemony note without a spoonful of mayo in sight.

• No mayo, no cook. A bright olive oil and lemon dressing replaces the heavy stuff, and nothing touches the stove.
• Ready in about 15 minutes. Whisk, chop, fold. That's the whole job.
• Meal-prep friendly. It holds beautifully in the fridge and the flavor only gets better after an hour or two.
• Naturally gluten-free. Serve it over greens or with pita and you're set either way.
• Easy to make a meal. A can of white beans turns this side into a filling lunch.

Ingredients You'll Need

Everything here is a pantry or produce-drawer staple. Nothing fancy, nothing you have to hunt down.

For the lemon-oregano dressing:

• Extra virgin olive oil (¼ cup). Use a good one since you'll taste it. This is the body of the dressing.
• Red wine vinegar (2 tablespoons). Brings the tang that makes it read Greek.
• Fresh lemon juice (2 tablespoons). Brightness on top of the vinegar. Fresh, not bottled.
• Dried oregano (1 teaspoon). The signature Greek note. Crush it between your fingers as you add it.
• Garlic (1 small clove, minced). Just enough for a savory backbone.
• Dijon mustard (½ teaspoon). A little helps the dressing emulsify and cling to everything.
• Salt and black pepper. To taste, but don't be shy with the salt.

For the salad:

• Canned tuna (two 5 oz cans). I reach for tuna packed in olive oil here. It's richer and more Mediterranean. Drain it well.
• English cucumber (1, chopped). Firmer and less watery than a regular cucumber, so it stays crisp.
• Grape or cherry tomatoes (1 pint, halved). Sweet little bursts in every forkful.
• Red onion (½, thinly sliced). Soak the slices in cold water for five minutes if you want a softer bite.
• Kalamata olives (½ cup, pitted and halved). Briny, meaty, and non-negotiable for me.
• Feta (⅓ cup, crumbled). Buy a block in brine and crumble it yourself. The pre-crumbled tubs are drier and chalkier.
• Fresh parsley (¼ cup, chopped). Dill works too if you love it.
• Optional: cannellini beans (one 15 oz can, drained). Stir these in to turn the salad into a full meal.

How to Make Greek Tuna Salad

The order matters here. Dress the vegetables first, then fold the delicate stuff in last so it stays intact.

Step 1: Whisk the dressing

Add the olive oil, red wine vinegar, lemon juice, oregano, garlic, Dijon, salt, and pepper to a jar.

Shake it hard, or whisk in a small bowl until it looks creamy and combined.

Set it aside so the flavors have a few minutes to mingle.

Step 2: Prep the vegetables

Chop the cucumber, halve the tomatoes, thinly slice the red onion, and halve the olives.

Toss them all into a large bowl with the chopped parsley.

Step 3: Dress the vegetables

Pour the dressing over the vegetables and stir until everything glistens.

This is your base, and it should already smell amazing.

Step 4: Fold in tuna and feta

Drain the tuna well and add it to the bowl along with the crumbled feta and the beans if you're using them.

Fold gently, just a few turns, so the tuna stays in tender flakes and the feta keeps its shape.

Taste, adjust the salt, and you're done!

Tips for the Best Greek Tuna Salad

A few small moves make the difference between watery and bright. None of them add real time.

• Drain the tuna hard. Press it against the lid to squeeze out the liquid. Wet tuna means a watery salad.
• Use block feta. Crumbled-from-a-block feta is creamier and tangier than the dry pre-crumbled stuff.
• Let it rest. Give the salad 10 minutes before serving so the dressing soaks in.
• Salt the tomatoes lightly. A pinch on the cut tomatoes wakes them up.
• Tame the onion. A quick cold-water soak softens the raw bite without losing the crunch.

Variations

This recipe takes well to swaps. Use what you have and make it yours.

• Make it a meal. Fold in a can of drained cannellini beans or chickpeas for staying power.
• Add a briny kick. A tablespoon or two of drained capers plays beautifully with the olives.
• Stir in roasted red peppers. Chopped jarred peppers add color and a soft, smoky sweetness.
• Serve it over romaine. Pile the salad onto crisp lettuce for a bigger, dinner-sized bowl.
• Swap the herbs. Fresh dill or a little mint both work in place of parsley.

What to Serve With Greek Tuna Salad

This salad plays nicely with almost anything. Here's how I like to round it out.

• Warm pita. Scoop it up or stuff it inside for a quick handheld lunch.
• In a wrap. Roll it into a tortilla with extra greens for an easy desk lunch.
• Over mixed greens. A bed of arugula or romaine makes it a full plate.
• Stuffed in a tomato or avocado half. Pretty, low-carb, and great for a light lunch.
• With crackers. Set it out as a dip-style appetizer at a gathering.

How to Store

This one is built for leftovers. It actually tastes better after a rest in the fridge.

• Refrigerator. Store in an airtight container for up to 3 days.
• Give it a stir. The dressing settles, so toss it before serving to redistribute the flavor.
• Meal-prep note. If you're prepping ahead, hold the feta and stir it in fresh each day so it stays in clean crumbles.
