10-minute Mediterranean tuna salad without mayo! With crunchy vegetables, fresh herbs, and a zesty Dijon dressing, this unique and healthy tuna salad recipe will be your new go-to!
Healthy tuna salad, the Mediterranean way
Unlike classic tuna salad, this unique tuna salad recipe is completely mayo-free–just like my healthy twist on the classic chicken salad. And, it takes on bold Mediterranean flavors thanks to loads of crunchy veggies, fresh herbs, and a bright Dijon dressing with lime juice and good extra virgin olive oil.
One of the best healthy tuna salad recipes on the site, this Mediterranean tuna salad is oh-so flavorful, and also perfectly light. While I love a composed nicoise salad and other hefty tuna salads with potatoes or rice, this easy tuna salad is likely my favorite. It is much quicker, and I can bulk it up any way I like for a fuss-free meal on the go.

What kind of tuna to use?
Tuna can be a wonderful, low-cost protein option. It is also nutrient-rich, containing essential vitamins, minerals, and omega-3 fatty acids.
There are a couple kinds of tuna out there, like white albacore and chunk light. Some are packed in olive oil, while others are packed in water.
I try to use wild-caught Yellowfin or Albacore tuna as much as possible. And if you’re concerned about the fat content, your best bet will be tuna packed in water instead of olive oil. I’ve used both in the past, but I now prefer to use tuna packed in water and then add my own extra virgin olive oil so I can control the flavor and the amount used.
Mercury levels in tuna can be a health concern, which is why my family eats it no more than once every two weeks. (Talk to your healthcare provider if you have concerns about eating canned tuna.)
Ingredients you need for the best tuna salad recipe
This healthy tuna salad comes together with just a few simple fresh ingredients and pantry staples. The key is to use good tuna and load it up with crunch and flavor using fresh ingredients you may already have on hand. Here’s what you’ll need to make it:
- Tuna – You’ll need 3 cans of quality tuna (5 ounces each), packed in water or olive oil. I use responsibly caught Yellowfin Albacore tuna (look for the dolphin-safe label).
- Vegetables – Cucumbers, celery, radish, and onions chopped into small bits will add crunch, texture, color, and nutrition.
- Fresh herbs – Chopped parsley and mint for great fresh, cooling flavor.
- Olives, capers, or pickles – Pitted and sliced kalamata olives or a handful of drained capers will add a nice briny and slightly salty flavor to this tuna salad recipe. This is a very Mediterranean thing to do, but if you’re not a fan of olives or capers, you can chop up some pickles instead.
The dressing
For the perfect tuna salad without mayonnaise, I make a zesty Dijon dressing with bold Mediterranean flavors. Here is what you need to make the dressing:
- Dijon mustard – Dijon adds tang to this dressing. And, because Dijon is an emulsifier, it thickens the dressing when mixed rapidly or blended and makes it creamy. So the dressing looks like it has mayo in it, but it doesn’t!
- Lime juice and lime zest – Adds acidity to brighten the dressing, and also to tame the “fishiness” of the tuna. You can use lemon juice and zest instead if you like.
- Extra virgin olive oil – A robust EVOO like our Hojiblanca Spanish olive oil is a good option, with its fruity notes and peppery finish.
- Spices: Sumac and crushed red pepper flakes – Sumac adds color and a tart citrus element to the dressing, which works well with the lime. And while crushed red pepper flakes are optional, I do recommend them. You only need ½ teaspoon, so you will get a very subtle heat.
How to make tuna salad
Once you’ve chopped up your veggies and fresh herbs, it takes very little time to put this Mediterranean tuna salad recipe together.
- Make the no-mayo salad dressing. Whisk together 2 ½ teaspoons Dijon mustard, the zest of 1 lime, the juice of 1 ½ limes, ⅓ cup extra virgin olive oil, ½ teaspoon sumac, and ½ teaspoon red pepper flakes (if you like a bit of heat). Season with kosher salt and pepper to taste.
- Put the tuna salad together. Drain the liquid out of the canned tuna (you need 3 5-ounce cans) and add it to a medium bowl. Add the chopped vegetables (celery, cucumber, radish, green onions, and red onion), chopped mint and parsley, and pitted kalamata olives (or capers).
- Dress the salad. Pour the zesty Dijon dressing all over the tuna salad ingredients and mix well. Cover and refrigerate for about half an hour. Before serving, gently mix the salad once more to redistribute the dressing.
Variations
There are so many ways to change up a simple tuna salad! Here are some other add-ins you could use for different textures and flavors:
- Chopped pink pickles or cucumber pickles
- Diced or grated carrots
- Chopped fresh fennel
- Chopped bell peppers
- Dried thyme or oregano
- Chopped fresh dill
- Tuna White Bean Salad with Spinach, Olives, and Basil
What goes with it: How to serve tuna salad
What goes well with tuna salad? Well, many things! It tastes so good in a sandwich or wrap, and makes a healthy appetizer or snack next to some fresh vegetables. Here are just a few ideas for serving tuna salad:
- Tuna Sandwich: Probably the most convenient way to serve tuna salad is in a sandwich. You can use any bread you like, but I make it a bit more Mediterranean by scooping it into warmed pita pockets instead.
- Tuna wraps! For a low-carb option, you can ditch the bread and simply serve the chunky tuna salad in lettuce wraps (something a bit similar to my shrimp lettuce wraps).
- Appetizer or snack: One of my favorite ways to serve this easy tuna salad is piling it onto tomatoes for a yummy hand-held snack or app. Try it over some roasted tomatoes or with this heirloom tomato salad. For an even easier shareable snack, surround a bowl of the salad to use as a dip with vegetable spears, pita chips, and your favorite crackers.
Make ahead tips
To work ahead, make the dressing a day or two in advance and keep it in the fridge in a tight-lid mason jar. You can also chop up the vegetables a night ahead and store them in airtight containers in the fridge.
How long does tuna salad last?
This homemade tuna salad will keep for about 3 days in an airtight container in the fridge. Just give it a good mix before serving leftovers.

I love tuna salad any way, and I love Mayo, but this looked interesting since I love all the veggie. Subbed lemon for lime. Didn’t have mint, but didn’t miss it. Really delicious and fresh tasting! Thanks for all your great recipes
My pleasure, Kay! Thanks for sharing!
I had been wanting to try something with my tuna sandwiches and I found this recipe. This was so incredible enjoyable and fresh tasting. I wanted to eat the whole bowl! Thanks for sharing this delicious recipe.
Such an easy and delicious salad this is! I left out the olives but didn’t notice them missing. Yes, a little extra zest and lime juice and wow, just perfect. It’s been requested numerous times now so definitely a keeper!
I made this and it really delivered, it was amazing. I am going to ditch mayo for this version from now on.
Thank you, Sonya!
I have a question regarding the tuna. Are you using solid white or flaked, or just regular tuna? Are you draining the tuna?
Hi, Colleen. For this recipe I mostly turn to responsibly caught white albacore tuna as it’s higher in heart-healthy omega-3 fats. If you’re using quality tuna in extra virgin olive oil, you can use the whole thing without draining. It really depends on what kind of tuna and whether you enjoy the taste of the canned olive oil or not. Another option would be to drain, and then add your favorite olive oil. Sometimes I do that so I can really control the amount of the oil in the recipe.
Delicious salad, very easy to make, I did not put radishes, I did not have but everything else if I had, super delicious since my son does not like mayo, so it was excellent.
Hi , going to try this Recipe . But i dont have Sumac and Radish . Its not available . Will serve this with whole whear pita toast .
Hi Suzy

For tuna so very delicious and easy to make
So nice to find a tuna salad to make healthy without mayonnaise So excited to try more of your recipes
Thank you for sharing recipes to be healthy and all look so delicious
Diane
Thanks, Diane! So glad you enjoyed it!
I loved this recipe….very robust flavors….I used only half of the recommended lime juice as my husband doesn’t like very sharp citrusy flavor….and it was brilliant…..one of my favorite pita bread filling recipes….thank you and God Bless 😊
Thanks Quarisha!
What can you use to substitute for sumac? not paying $9 for a jar of spice I’ll use once.
Never mind, I found my answer: If you cannot find sumac at the market, there are a few substitutions you can use to achieve a similar taste. Lemon zest can be used in its place or combine the zest with salt and black pepper for a more complex flavor.
I absolutely love this recipe. It was very easy to make and so healthy and delicious. I’ve eaten it as a main for lunch and as a side dish either way this dish is great. The only change I made, was adding extra lime – for extra zing
Thanks so much, Louise!
WOW! I was a bit worried to try this because I dont like vegetables in my tuna normally, but wanted to eat healthier so decided to try it out. This was AMAZING! Hands down the best tuna I’ve ever had. You don’t even really taste the individual vegetables, instead everything blends together beautifully to create a wonderful texture and flavor profile of its own! This recipe is a must try, and a staple for me now!
Thank you for sharing, Michelle!!
SO SO GOOD. The flavor from the dijon gives it a nice zestiness. I subbed lemon juice because I didn’t have any lime on hand and it was fine. Local grocery store didn’t have sumac so I used zaatar and loved the flavor. I wasn’t sure about the mint since I’m usually not a big fan, but I left it in and I’m super glad I did-it gave the dish a good brightness. I have already sent this recipe to the rest of my family- can’t wait to make it again!
Wonderful! Thanks you so much, Lauren!!
I love that you add mint leaves to everything. Makes a big deference. This salad was nothing what I expected. That flavor was elevated with the dressing and mint added some lightness to it.
I agree… a little mint can make many dishes extra special :). Thanks, Tanya!
Have you ever sautéed the onions? My tummy doesn’t like raw onions.
I have not, but you could certainly give it a try!
Love your recipes Suzy!
Can you sub lemon juice for lime juice for this recipe ?
Thank you
Absolutely!
