A Fresh Take on a Classic Dish
There’s something magical about stumbling upon a recipe that transforms everyday ingredients into something extraordinary. That’s exactly what happened when I first made this no-mayo potato salad with tuna. It was born out of necessity one hot summer afternoon when I realized I had no mayonnaise but still craved a satisfying potato salad. Little did I know this “plan B” would become one of my most requested recipes!
What makes this Mediterranean-inspired potato salad special is its bright, zesty flavors that come from fresh lemon juice, good olive oil, and aromatic herbs. The addition of tuna transforms it from a side dish into a complete meal that’s perfect for lunch, dinner, or even packed for a picnic.
If you’re looking for a lighter, healthier alternative to traditional mayo-laden potato salads or if you simply want to try something new, this recipe is definitely worth a spot in your regular rotation. Let me share why this dish has become such a staple in my kitchen and how you can make it your own.

This isn’t just any potato salad—it’s a Mediterranean delight that brings together the best flavors of the region in one bowl. Here’s why I think you’ll fall in love with it just as I did:

Key Ingredients for Mediterranean Potato Salad
The beauty of this salad lies in its simplicity and the quality of ingredients. Here’s what you’ll need:
The Foundation
- Baby Potatoes: Their waxy texture holds up well in salads without becoming mushy. I prefer a mix of red, yellow, and purple for visual appeal.
- Quality Tuna: Look for tuna packed in olive oil for the best flavor, though water-packed works too if you prefer a lighter option.
The Flavor Builders
- Extra Virgin Olive Oil: This is where you want to use the good stuff! A fruity, high-quality olive oil makes all the difference.
- Fresh Lemon Juice: Adds brightness and helps cut through the richness of the tuna and potatoes.
- Dijon Mustard: Provides a slight tang and helps emulsify the dressing.
Fresh Elements
- Red Onion: Adds a sharp, crisp element that balances the softness of the potatoes.
- Bell Peppers: I like using a mix of colors for visual appeal and varied sweetness.
- Cucumber: Provides refreshing crunch and helps lighten the overall dish.
- Cherry Tomatoes: Their burst of sweetness complements the savory elements perfectly.
Herbal Notes
- Fresh Parsley: Adds a clean, bright flavor that’s quintessentially Mediterranean.
- Fresh Dill: Optional but highly recommended for its distinctive aroma.
- Capers: These little flavor bombs add briny, salty notes that elevate the entire dish.
Step-by-Step Instructions
Creating this salad is straightforward, but there are a few key techniques that make all the difference:
Preparing the Potatoes
- Select the Right Potatoes: Choose waxy varieties like Yukon Gold, red potatoes, or fingerlings. They hold their shape better in salads.
- Cook Them Properly: Place whole baby potatoes in cold, salted water and bring to a boil. Reduce to a simmer and cook until just tender when pierced with a fork (about 15-20 minutes depending on size).
- Cool Them Strategically: Drain the potatoes and let them cool just enough to handle. Cutting them while still warm helps them absorb the dressing better.
- Season Immediately: Toss the warm potato chunks with a bit of the dressing right away—this is my secret for flavor-packed potatoes!
Creating the Perfect Dressing
For the dressing that brings everything together:
- Whisk Together: In a small bowl, combine 1/3 cup extra virgin olive oil, juice of 1 large lemon, 1 tablespoon Dijon mustard, 2 cloves minced garlic, 1 teaspoon dried oregano, salt, and pepper.
- Taste and Adjust: This is crucial! Everyone’s lemons and olive oils have slightly different flavors. Taste and adjust the acid-to-oil ratio to your preference.
- Add Herbs Last: Stir in most of the chopped fresh herbs at the end, reserving some for garnish.
Assembling the Salad
- Layer the Flavors: Start with dressed potatoes in a large bowl.
- Add Vegetables: Fold in diced red onion, bell peppers, cucumber, and halved cherry tomatoes.
- Incorporate Tuna: Gently fold in drained tuna, breaking it into chunks rather than flaking it too finely.
- Final Touches: Add capers, remaining herbs, and a final drizzle of your best olive oil.
- Rest Before Serving: Let the salad sit for at least 30 minutes before serving to allow flavors to meld.

Potato Perfection
- Salt the Cooking Water: Make it taste like sea water for well-seasoned potatoes from the inside out.
