Ingredients
Salad
- Skipjack tuna
- Veggies: Bell peppers, red onion, cucumber, roasted red peppers
- Capers (or chopped kalamata olives) – for a briny, salty addition to the tuna salad, and I think they help make this salad extra-ordinary in flavor.
- Fresh flat leaf parsley – flat leaf parsley helps to add a fresh element to the salad and really helps to make the flavors fresh and bright. You could also use fresh mint, basil or fresh oregano (not as much oregano as parsley though as it’s overpowering)
Dressing for tuna salad:
- Lemon juice (you could also use white wine vinegar or red wine vinegar)
- Olive oil
- Dijon mustard
- Spices: Herbs de Provence (or Italian seasoning), salt, garlic powder
How to make tuna salad without mayo
Drain the tuna, add it to a large bowl. Chop the veggies (bell peppers, cucumber, red onion, parsley and capers) and add to the bowl with the tuna. 
In a glass bowl or jar, add together the lemon dressing ingredients (lemon juice, olive oil, dijon mustard, herbs and salt). 
Whisk the dressing well until combined (alternatively you can shake the jar if you have a well sealing lid). 
Pour the dressing over the tuna salad and veggies. 
Stir well to fully incorporate the dressing over the tuna and veggies. Serve like this or in a wrap, on bread or in a salad.
Other additions
Although I love this salad exactly as written, I know sometimes you need to make substitutions or have other veggies on hand you might want to add. Here are some great additions:
- Veggies: Shredded carrots, chopped celery, cooked broccoli, asparagus or cauliflower, chopped into small pieces
- Canned veggies like artichoke hearts, olives, hearts of palm
- Fresh herbs like dill, mint, oregano or basil
- Pop of flavor: Add a few chopped sundried tomatoes, crushed red pepper flakes or lemon zest

Recipe Notes
- Drain the tuna well. Excess liquid can make the salad soggy, especially if you’re using tuna packed in water or oil.
- Check the salt. If your tuna is already salted, you may want to leave it out of the dressing until you taste it together.
- Want extra dressing? Double the dressing if you plan to serve the tuna salad over greens or grain bowls, it makes a great all-purpose vinaigrette.

Common questions
What is the best kind of tuna to use for tuna salad
I personally love tuna packed in olive oil—it adds more flavor and richness. But this recipe also works great with tuna in water, especially skipjack or albacore.
Tip: When buying canned tuna, look for labels like pole caught, line caught, or troll caught to ensure more sustainable fishing practices.
Can I make the dressing creamy
Yes! If you prefer a creamy tuna salad without mayo, try adding:
- 2 tablespoons of Greek yogurt
- Mashed avocado
- Blended cottage cheese
- Or use tahini in place of olive oil, with 1–2 tablespoons of water to thin it out
Can I make this in advance
Absolutely. This tuna salad keeps well in the fridge for up to 24 hours and the flavors actually improve overnight. Just note that the veggies may soften slightly, so it’s best enjoyed within a day if you’re prepping it for guests.
Storing leftovers
- Fridge: Store in the fridge in an airtight container for up to 3 days. The veggies may start to get soft at this point, but the flavor will still be delicious!

What else could you use this dressing on?
Thank You
Hey Eileen! That’s a great question. This lemon dressing is pretty versatile. You could use it over salad greens or over chicken salad or even pasta salad!
Dressing taste fabulous. TKS for this recipe!
Made this today for lunch, and it was a such a nice change from standard tuna salad. I will be adding this to my lunch rotation. Yum!
This was so good! Used green olives instead of capers. Making it again today.
Yum that sounds delicious! Thank you for taking the time to leave a quick comment!
This is so good! I was searching for Greek style salads that are safe to have during pregnancy, as I’ve been craving something fresh, but can’t have feta cheese right now. I also sometimes struggle with tuna salads as they can be a bit too fishy. But this salad was not fishy at all, it has a wonderful fresh tangy flavour which is really well balanced, and the flavours all come together beautifully.
I used a large can of chunk style tuna in olive oil. I also didn’t have parsley so I used fresh mint. I also added olives as well.
I’ll definitely be making this salad regularly – it’s going to become one of my staples.
Thank you for such a lovely recipe!
I loved this the first time I made it. The 2nd time it was so salty I could barely eat it. Turns out the skipjack tuna includes sea salt. Way too salty especially with the added salt in the recipe and the lemon juice. ugh. Skipjack does have a no salt added tuna. you definitely need this.
Yummy! I substituted celery for the cucumber because I was out and thought it turned out great. I think it would taste good over some greens as well as on its own.
I will use Italian seasoning next time. Also, I will de-seed the cucumber. My salad was a little too wet otherwise.
Excellent and easy recipe
So easy, healthy and delicious. It’s a hit with the family—I make it once a week.
Do you think this recipe would be good for meal prep? Could it be stored for three days?
It could easily last 3 days without the cucumbers. Cucumbers tend to get watery over time.
I’ve never made tuna salad this way before–I loved all the add-ins. Delicious and easy. It was a hit with my family!
That was the best tuna salad I have ever had.
This looks fanstastic, it will be a great way to encourage my children to enjoy vegetables. Thanks so much for the yummy recipe Samantha!
