Mediterranean Tuna Salad – Low Carb Keto Recipe

I don't usually make tuna salad, but I was inspired by two things. First, we were back in Greece in April after five years away. I was reminded of this absolutely delicious keto tuna salad I had there. In my mind, two things made it perfect, the fact that it was a tuna salad without mayo and the use of lemon and lemon zest. Just being in that beautiful place again made me want to create this Mediterranean Tuna Salad recipe.

Making Mediterranean tuna salad low carb is easy. The only carbs in this dish come from vegetables. I've said this before, but carbs from vegetables don't seem to affect me at all. Your mileage may vary but with only 7 total carbs and 5 net, it should fit into your keto macros nicely.

It's usually when people make a tuna salad recipe into a sandwich or serve it with chips that it becomes higher carb. Most tuna salad recipes are naturally low-carb.

Keto Tuna Salad Recipe Serving Ideas

If you're missing a sandwich, feel free to wrap up this delightful Mediterranean tuna salad in a low-carb wrap if you're not bothered by gluten. Or use our Keto Carnivore Wrap recipe to keep it super clean. Another great serving idea is to place some beautiful butter lettuce leaves on a plate, then the tuna on top. You can also use a large lettuce leaf as a wrap. I prefer to eat it straight out of the bowl!

As for other ingredients you can serve this with, I love it topped with some perfect boiled eggs. Avocado is also amazing as are capers and toasted pinenuts. I have to be careful about how many (or any) olives I put in dishes because my husband doesn't like them. I know, weirdo, lol. However, a few extra olives here as a garnish or mixed in the tuna salad would be delicious.

What Makes a Mediterranean Tuna Salad?

If you're wondering what elevates the humble tuna salad into a Mediterranean tuna salad, it's all in the ingredients. No mayo here which means no crappy oils, although you can certainly make your own to keep it super healthy. Lemon, feta and extra virgin olive oil are quintessentially Greek ingredients.
