Ingredients You’ll Need
The magic of this Cucumber Tuna Salad Recipe lies in its simplicity. Each ingredient is carefully chosen to give you layers of flavor and delightful texture, from the crisp cucumber to the seasoning that brightens every bite.
- Tuna (1 can, 5 oz, drained): The protein-packed base that offers a mild, meaty flavor perfect for salads.
- Cucumber (½ cup, diced): Adds a refreshing crunch and subtle sweetness that balances the tuna’s richness.
- Onion powder (¼ tsp): Provides a gentle hint of savory depth without overpowering the other ingredients.
- Dill (1 tsp dried or 1 tbsp fresh, chopped): Introduces a fragrant, herbaceous note that brightens the entire salad.
- Mayonnaise (2 tbsp): Brings creaminess and binds the salad together for a luscious texture.
- Dijon mustard (1 tsp): Offers a subtle tang and a touch of spice to lift the flavors.
- Salt and black pepper (to taste): Essential seasonings to enhance and balance the overall flavor profile.
How to Make Cucumber Tuna Salad Recipe
Step 1: Prepare the Ingredients
Start by draining your canned tuna thoroughly to avoid any excess moisture in your salad. Place the tuna in a medium-sized bowl as the foundation of your dish. Next, dice the cucumber into small, bite-sized pieces to ensure every forkful gets a perfect balance of crunch and creaminess.
Step 2: Combine Ingredients
Add the diced cucumber directly to the bowl with the tuna. Sprinkle in the onion powder and dill, then dollop the mayonnaise and Dijon mustard on top. These ingredients will come together to create that signature flavor blend that makes this recipe so appealing.
Step 3: Mix Together
Gently stir the mixture until all the ingredients are evenly combined. Take care not to mash the cucumber too much; you want those crisp pieces to stand out and provide texture contrast with the soft tuna and creamy dressing.
Step 4: Season to Taste
Finally, taste your salad and season with salt and black pepper as needed. This final step personalizes your salad to your liking, whether you prefer it a bit saltier or with a peppery kick.
Step 5: Serve or Chill
The Cucumber Tuna Salad Recipe is ready to enjoy immediately, bursting with fresh flavors. Alternatively, you can refrigerate it for a short time to let the flavors meld even more, perfect for a make-ahead lunch option.
How to Serve Cucumber Tuna Salad Recipe

Garnishes
Sprinkle a little extra fresh dill or a sprinkle of finely chopped green onions on top for a pop of color and a hint of added flavor. A wedge of lemon on the side can be squeezed over just before eating to brighten the dish even further.
Side Dishes
This salad pairs wonderfully with crunchy whole grain crackers, toasted slices of baguette, or even wrapped in a crisp lettuce leaf for a low-carb bite. For a more complete meal, serve alongside a light vegetable soup or a simple bowl of mixed greens to complement the salad’s freshness.
Creative Ways to Present
For a fun twist, stuff the salad inside hollowed avocados or tomatoes, turning the dish into an elegant appetizer. You can also serve it over a bed of baby spinach or arugula for a more substantial salad variation that feels a bit more dressed up.
Make Ahead and Storage
Storing Leftovers
Once prepared, store any leftover cucumber tuna salad in an airtight container in the refrigerator. It’s best enjoyed within 1 to 2 days to maintain the fresh crunch of the cucumber and the overall deliciousness of the salad.
Freezing
This salad is not ideal for freezing due to the mayonnaise and cucumber content, which can separate or become watery when thawed. It’s best to enjoy it fresh or refrigerated rather than frozen.
Reheating
Since this dish is meant to be served cold or at room temperature, reheating is not recommended. Simply take it out of the fridge and let it sit a few minutes before serving, if you prefer it slightly less chilled.
FAQs
Can I use fresh tuna instead of canned tuna?
While fresh tuna can be used, it requires cooking first and will change the texture and prep time significantly. This Cucumber Tuna Salad Recipe is designed for the convenience and flavor of canned tuna, making it quick and easy.
What can I substitute for mayonnaise?
You can swap mayonnaise for Greek yogurt or a light vinaigrette to make the salad lighter. Just keep in mind the texture and tang will differ slightly from the original creamy profile.
Is this salad suitable for meal prep?
Yes! The salad holds up well in the refrigerator for up to two days, making it a fantastic choice for meal prepping lunches or snacks.
Can I add other vegetables to this salad?
Absolutely! Chopped red onions, bell peppers, or even cherry tomatoes can add extra color and flavor. Just be mindful that additional moisture-heavy veggies might alter the texture slightly.
How do I make this salad gluten-free?
The recipe is naturally gluten-free, but be sure to double-check your canned tuna and other ingredients to avoid any hidden gluten additives if you’re sensitive.
