Mediterranean Tuna Salad

The first time I made this tuna salad was on a brutally hot July afternoon when even the thought of turning on the stove felt unbearable. I had just returned from the farmers market with a bag of cherry tomatoes that looked like tiny jewels and a cucumber so fresh it still had the dew on it. Standing in my swimsuit with the back door open to catch any hint of breeze, I threw everything together in a bowl, not really measuring anything. That impromptu lunch became the only thing I wanted to eat for the rest of the summer.

Last summer my neighbor caught me making this on my back porch and ended up staying for lunch. We ate it standing at the counter with forks, talking about how something so simple could taste so expensive. Now she texts me whenever she sees tuna on sale, and I know exactly what shes planning.

Ingredients

• Tuna in olive oil: Trust me on this, the oil-packed variety makes a huge difference in flavor and texture
• Cherry tomatoes: When you halve them they release just enough juices to mingle with the dressing
• English cucumber: Fewer seeds and a more delicate crunch than regular cucumbers
• Red onion: Slice it paper thin so you get the flavor without the sharp bite
• Roasted red peppers: Jarred ones work beautifully here and add a subtle sweetness
• Fresh parsley: It brings this undeniable Mediterranean brightness that dried herbs cannot replicate
• Kalamata olives: Their brininess is the secret that ties everything together
• Capers: Rinse them well to remove excess salt but keep that distinctive tangy punch
• Extra virgin olive oil: Use the good stuff since it is one of the main flavors
• Fresh lemon juice: Squeeze it right before you dress the salad for maximum brightness
• Garlic clove: Mince it finely so you do not bite into large chunks
• Dried oregano: The dried version actually works better here than fresh for an earthy undertone

Instructions

Prep the tuna:

Open those cans and drain the tuna but do not squeeze it dry, that olive oil is pure flavor waiting to happen

Chop your vegetables:

Halve the cherry tomatoes, dice the cucumber into small pieces, and slice that red onion as thin as you possibly can

Combine everything:

Toss the tuna, vegetables, roasted peppers, parsley, olives, and capers into your largest mixing bowl

Make the dressing:

Whisk together the olive oil, lemon juice, garlic, oregano, salt and pepper until it looks silky and emulsified

Dress and serve:

Pour the dressing over the salad, toss gently to coat everything without breaking up the tuna too much, then taste and adjust the seasoning before serving

Save to Pinterest

This recipe has become my go-to for those nights when I want something satisfying but not heavy. There is something about the combination of briny olives, bright lemon, and tender tuna that just works every single time.

Make It Your Own

I have found that adding a handful of arugula or fresh basil transforms this into something entirely new. Sometimes I toss in some diced avocado when I want it more substantial, and it is absolutely perfect.

Serving Suggestions

Serve this inside a hollowed out tomato for a presentation that looks fancy but takes zero extra effort. It also works beautifully stuffed into a pita pocket or served alongside some crusty bread that has been rubbed with garlic.

Make Ahead Magic

This salad actually tastes better after a few hours in the refrigerator, which makes it perfect for meal prep or picnics. Just hold off on adding the dressing until right before you plan to eat it.

• Store the dressing in a separate small container
• Give the tuna salad a quick toss before serving to redistribute the flavors
• It keeps beautifully for up to three days in the refrigerator

Whether you are eating it from a bowl on the back porch or packing it for a beach day, this salad is summer simplicity at its absolute best.
