Once the weather warms up, I start craving food that feels fresh and satisfying without asking me to turn my kitchen into a sauna. That’s exactly why I keep coming back to cucumber tuna salad. The cucumbers stay crisp, the dressing is creamy in that just-right way, and the tuna gives it enough heft to count as a real meal. I’ll pull it together in 10 minutes for a light lunch after church, or, honestly, just when I need something quick between errands that still feels like a good choice.

Ingredients You Will Need
Here’s a quick overview of the key ingredients for this recipe. For the full list of ingredients and exact measurements, be sure to check the recipe card at the bottom of this post.
- Tuna: Choose water packed tuna for a lighter option. If you prefer a richer texture, tuna in olive oil works well too.
- Cucumbers: Mini cucumbers are best for fewer seeds and extra crunch. You can also use English cucumbers if mini aren’t available.
- Mayonnaise: Any good quality mayo works. Swap in Greek yogurt for a lighter, tangier version.
- Dijon Mustard: Gives a tangy zip and unique flavor. You could also try making your own mustard with this How To Make Mustard At Home guide.

Yes, but the texture will be richer and you may need less mayo.
You can, but scoop out the seeds to prevent excess moisture.

Gina’s Recipe Tips and Variation Ideas
Dietary Modifications: Swap mayo for plain Greek yogurt for a lighter, higher-protein option. It will be a bit more tangy, however. Use vegan avocado oil mayo for a dairy-free option.
Flavor Enhancements: Add lemon juice for extra brightness, or stir in chopped green onions or parsley for more herbal notes.
Add In Options: Mix in chopped celery for crunch chopped hard-boiled eggs for extra protein, or a pinch of red pepper flakes or sriracha for heat.
Simple Substitutions: Use tuna in olive oil for a richer flavor, or add mashed avocado instead of mayo for a creamy, dairy-free twist.

Hi Gina. I recently came upon your website… looked around at your recipes and I liked the recipes I looked at.
I have to admit that I’m not normally a fan of canned tuna but am willing to try this recipe as I already have the ingredients. I bought a can of tuna at the store to try to acquire a taste for it waiting for a recipe which looked like something I would like to eat, and this is it. I love the fact it has mini cucumbers and have not seen a tuna recipe before this which called for cucumbers. Maybe there is one somewhere but not looking any further as I’m going to try this.
After I make this, I will rate it.
I figured coming from a mother of six and a grandmother of 17 you have the experience. lol I look forward to trying other recipes from you.
Thank you.
Tricia, Here is a truth, my husband doesn’t like tuna – no matter how I try to disguise it. However, most of the family does! I hope you enjoy it. The cucumbers make it lighter, less fishy so to speak.
Yes, you’re right. The cucumbers made a difference… and less “fishy” taste. I promise you I did not taste the tuna in this salad. I did squeeze lemon to brighten the salad up and I think it helped, too.
I’m thinking of making the Zesty Mexican Macaroni Salad next to carry to a potluck gathering.
Let me know how it turns out for the potluck.
I made it yesterday after I sent you a comment regarding my not liking to eat canned tuna… however, after making this yesterday I can now say I really like this recipe and it’s because of your particular recipe that I will now eat canned tuna. BTW I really loved the crispness of the english (mini) cucumbers!!
Thanks Gina for converting me.
So happy to hear this Tricia!
