Tuna Salad Recipe Without Mayo: Greek Yogurt Twist With Crunchy Veggies

This tuna salad swaps mayo for Greek yogurt, creating a lighter yet creamy base that lets the fish shine. The addition of crisp vegetables adds fresh texture without overpowering the main ingredient.

What results is a protein-packed meal that’s both satisfying and nutritious. Perfect for sandwiches, wraps, or enjoying straight from the bowl.

Ingredients for Tuna Salad Recipe Without Mayo

Light yet creamy tuna salad with crisp veggies and a tangy Greek yogurt base.

The tuna is the backbone—wild-caught in water (not oil) keeps the flavor clean. Trader Joe’s or Safe Catch are reliable brands for quality. Greek yogurt needs to be full-fat to mimic mayo’s richness without the cloying aftertaste. For the celery and cucumber, look for firm, unblemished stalks (the crunch is non-negotiable). Fresh dill is worth the splurge—dried just doesn’t deliver the same pop.

No Greek yogurt? Sour cream or labneh work in a pinch (though slightly tangier). Out of fresh dill? Fresh parsley or tarragon can sub at equal amounts. Capers missing? Chopped cornichons or a dash of brine adds similar acidity. The Dijon mustard is key for depth—yellow mustard lacks complexity. Skip the cucumber if you hate the texture, but replace it with something crunchy like bell pepper.

This keeps 3-4 days in the fridge, sealed tight. The flavors meld overnight, so it’s actually better the next day. Don’t freeze—yogurt separates unpleasantly. Serve chilled for best texture (that creamy, crisp contrast stays intact).

Step-by-Step Instructions for Tuna Salad Without Mayo

This method ensures a creamy, flavorful salad with the perfect balance of textures and bright notes.

Step 1: Drain and Flake the Tuna

Open the 2 cans Canned Tuna in Water and drain them thoroughly in a fine-mesh strainer. Press gently with a spoon to remove excess liquid—this prevents a watery salad. Transfer the tuna to a large mixing bowl and flake it with a fork until it separates into even, bite-sized pieces.

The tuna should look dry and crumbly, with no large clumps. I always check for any remaining bones or dark bits and remove them for a smooth texture. This step sets the foundation for a salad that clings to every ingredient.

Step 2: Prepare and Combine the Vegetables

In the same bowl, add the 1 cup Celery, 0.25 cup Red Onion, and 0.5 cup English Cucumber. The celery should be finely diced for consistent crunch, while the red onion and cucumber add sharpness and freshness.

Add the 2 tbsp Fresh Dill and 1 tbsp Capers for a bright, briny kick. Gently fold everything together with a spatula, ensuring the vegetables are evenly distributed. The dill’s aromatic quality should be noticeable but not overpowering.

Step 3: Whisk the Dressing

In a small bowl, combine the 0.75 cup Plain Greek Yogurt, 1 tbsp Dijon Mustard, 2 tbsp Lemon Juice, 1 tbsp Extra-Virgin Olive Oil, 0.5 tsp Kosher Salt, and 0.25 tsp Freshly Ground Black Pepper. Whisk vigorously until the mixture is smooth and fully emulsified.

The dressing should have a tangy, creamy consistency with a slight sheen from the olive oil. Taste and adjust the Kosher Salt if needed, but remember the capers and tuna add saltiness too. This step ensures every bite is well-coated and flavorful.

Step 4: Fold Everything Together

Pour the dressing over the tuna and vegetable mixture. Using a spatula, fold gently until all ingredients are evenly coated. Avoid overmixing, which can break down the tuna and vegetables into a mushy texture.

Let the salad sit for 5-10 minutes to allow the flavors to meld. The yogurt will soften slightly, and the vegetables will release some of their natural juices, creating a balanced, cohesive dish. The final result should be creamy but not soggy, with visible flecks of dill and capers throughout.

Essential Equipment for This Dish

Must-Have Tools

To whip up this tuna salad without mayo, you’ll need a few kitchen staples. A sharp chef’s knife (like Wüsthof or Victorinox) is essential for finely dicing veggies, while a mixing bowl ensures even blending of ingredients. A cutting board (preferably wooden) keeps prep organized and protects your counters.

Don’t forget a sturdy fork or whisk to mash the tuna and mix in the Greek yogurt. For precision, a measuring cup set helps balance flavors without guesswork.

Nice-to-Have

A food processor (like the Cuisinart Mini-Prep) can save time chopping veggies, and a citrus juicer makes adding fresh lemon juice a breeze. If you love texture, a mandoline slicer creates paper-thin cucumber ribbons for garnish.

For serving, a slotted spoon helps drain excess liquid, and a set of glass meal-prep containers keeps leftovers fresh for days.

Budget Alternatives

Skip the fancy gadgets and use a butter knife for mixing and a standard veggie peeler for quick cucumber strips. A mason jar doubles as a mixing bowl and storage—just shake and go! For chopping, a paring knife works in a pinch.

No food processor? A grater can shred carrots or celery for a similar crunch. The key is creativity—great tuna salad doesn’t require expensive tools!
