Creamy Tuna Cucumber Salad (Ready in 10 Minutes)

This creamy tuna cucumber salad comes together in about 10 minutes with just a handful of ingredients. It’s cool, crisp, and exactly the kind of thing you want on a warm night when turning on the stove feels like a bad idea.

The dressing leans on both mayonnaise and yogurt so it stays creamy without being heavy. A little lemon and dill keep it bright, and the cucumber gives you that crunch in every bite.

Why This Salad Works

The Greek yogurt cuts through the richness of the mayo but still gives you a coating that clings to the tuna and cucumber. You get creaminess that feels light, not gloppy.

Cucumber is the real star here. It keeps the texture fresh and snappy even after you mix everything together, so the whole bowl tastes like a cool summer lunch.

Ingredients

• 2 cans (5 oz each) tuna in water: drained well, water-packed keeps it light
• 1 English cucumber: no need to peel, dice into small chunks (about 2 cups)
• 1/4 cup mayonnaise: use full-fat for the creamiest feel
• 1/4 cup plain Greek yogurt: adds tang and lightness
• 1 tablespoon fresh lemon juice: brightens the whole thing
• 1 teaspoon dried dill: use 1 tablespoon fresh if you have it
• 1/2 teaspoon salt: adjust to your taste
• 1/4 teaspoon black pepper: freshly ground gives the best bite

Variations / Substitutions

• Swap the tuna for canned salmon: it gets a richer, slightly sweeter flavor
• Add a little crunch: fold in 1/4 cup diced celery or red onion right before serving
• Use a different herb: fresh chives or parsley work just as well as dill
• Leave out the yogurt: use an extra 1/4 cup mayo, but expect a heavier dressing
• Give it some heat: a pinch of cayenne or a spoonful of chopped pickled jalapeños wakes it up

Bourbon Glazed Salmon is the main dish we love pairing with this salad.

How to Make Tuna Cucumber Salad

Step 1: Whisk the Dressing

In a medium bowl, whisk together the 1/4 cup mayonnaise, 1/4 cup yogurt, 1 tablespoon lemon juice, 1 teaspoon dill, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Whisk for about 30 seconds until the dressing is completely smooth and no streaks of mayo remain.

Step 2: Fold in the Tuna and Cucumber

Drain the 2 cans of tuna really well, pressing gently on the lid to get out as much water as possible, then add the tuna to the bowl along with the diced cucumber. Use a fork to break the tuna into flakes and gently fold it through the dressing for about 30 seconds. You want every piece coated but the cucumber staying crisp.

Step 3: Spoon Into Bowls

Spoon the salad straight into individual bowls. Finish with a crack of black pepper and a small sprig of fresh dill if you have some. Eat right away for the crunchiest cucumber, or let it sit for 2 minutes so the flavors settle.

A Few Notes Before You Start

• If your dressing feels too tight, loosen it with a teaspoon of cold water or an extra squeeze of lemon.
• For a lighter option, replace all the mayonnaise with yogurt, but know it will be tangier and less rich.
• Crushed butter crackers or toasted pita chips on top add a nice crisp contrast if you feel like gilding the lily.

Scale it up for potlucks or meal prep:

Storing Leftovers

• Refrigerate: cover tightly and keep up to 2 days. The cucumber will release liquid as it sits, so stir it well and pour off any extra water before eating.

What to Serve With Creamy Tuna Cucumber Salad

This salad on its own makes a solid lunch, but it also turns into a great sandwich. Pile it onto toasted sourdough with a few leaves of butter lettuce for crunch. For a low-carb route, scoop it into romaine or butter lettuce cups. A cup of chilled tomato soup on the side rounds out the plate without any extra cooking.

Frequently Asked Questions

Can I use regular cucumbers instead of English cucumber?

Yes, just peel them first and scoop out the seeds so the salad does not get watery.

My salad turned out watery, why?

The two biggest reasons are tuna that wasn’t drained enough and cucumbers that weren’t patted dry. Even a little extra moisture in the bowl will thin out the dressing quickly.

Can I skip the yogurt and use only mayonnaise?

You can. The flavor gets richer and a little heavier, but it still works. Sour cream is another good swap for the yogurt.

Is this tuna cucumber salad gluten-free?

It is. Every ingredient here is naturally gluten-free, just double-check your mayonnaise label to be sure.

Notes

If you let the salad sit, even for 5 minutes, the cucumber starts to release water. Give it a quick stir and drain any excess liquid before serving. A few crushed crackers on top add a nice crunch.
