This vibrant Mediterranean-style tuna salad comes together in just 15 minutes with no cooking required. Flaky tuna in olive oil pairs beautifully with cherry tomatoes, crisp cucumber, roasted red peppers, red onion, and briny Kalamata olives.
The zesty lemon-olive oil dressing with garlic, oregano, and capers ties everything together with bright Mediterranean flavors. It's perfect for a refreshing light lunch, healthy dinner, or meal prep for busy weekdays.
Keep it dairy-free and gluten-free as written, or serve over mixed greens with crusty bread for a heartier meal. The flavors develop beautifully when chilled for a couple of hours before serving.
Last summer my neighbor brought over this salad after I complained about the heat making cooking impossible. One bite and I was immediately asking for the recipe.
Ive started making double batches because my husband keeps eating it straight from the bowl with a fork while Im trying to photograph it for friends who ask.
Ingredients

My sister in law from Greece tasted this and said it reminded her of lunches on her fathers balcony overlooking the Aegean.
Make It Your Own
Sometimes I swap in fresh basil when my parsley plant has bolted or add avocado when I want something creamier. The base formula works with whatever garden overflow is sitting on my counter.
Serving Suggestions
Weve eaten this over mixed greens stuffed into pita pockets and simply spooned onto crackers during impromptu wine nights. Its versatile enough to work as a light main or substantial side.
Storage Tips
This keeps beautifully for about two days though the vegetables will soften slightly. Actually some days I think it tastes even better after the flavors have had time to really get acquainted.
- Store in an airtight container in the refrigerator
- Bring to room temperature 15 minutes before serving
- Add fresh herbs right before serving if you have them on hand
Hope this becomes your go to for those too hot to cook days when you still want something satisfying.
Recipe FAQs
- → How long does Mediterranean tuna salad last in the refrigerator?
-
This tuna salad stays fresh for up to 2 days when stored in an airtight container in the refrigerator. For best texture and flavor, add dressing just before serving rather than storing it dressed.
- → Can I use water-packed tuna instead of oil-packed?
-
Yes, water-packed tuna works perfectly fine. You may want to increase the olive oil in the dressing slightly to compensate for the lost richness. The overall flavor will still be delicious.
- → What can I substitute for capers if I don't have them?
-
Chopped green olives or a splash of red wine vinegar can provide similar tangy, briny notes. Small diced dill pickles work too, though the flavor profile will shift slightly.
- → Is this tuna salad suitable for meal prep?
-
Absolutely! You can chop all vegetables and mix the dressing up to 2 days ahead. Keep components separate and combine just before eating for the freshest texture. It's perfect for grab-and-go lunches.
- → Can I add other vegetables to this Mediterranean tuna salad?
-
Certainly! Try adding diced bell peppers, radishes, artichoke hearts, or fresh spinach leaves. Avocado adds creaminess, while feta cheese provides a salty tang if you eat dairy.
