This Cucumber Tuna Sandwich is a refreshing bite with creamy tuna and crisp cucumber slices. It’s perfect for a quick lunch or snack!
Honestly, the crunch from the cucumber makes it feel like a mini party in your mouth! I love it served with a side of chips for some extra crunch. 😊
It’s super easy to whip up—just mix the tuna, spread it on bread, and layer those cucumbers. In no time, you’re enjoying a tasty sandwich that feels quite fancy!
Key Ingredients & Substitutions
Tuna: I recommend using canned tuna in water for a lighter option. If you’re looking for a healthier choice, consider using canned salmon or even chickpeas for a vegetarian version.
Mayonnaise: Regular mayo gives great creaminess, but feel free to use Greek yogurt for a lighter, tangy twist. You could also use vegan mayonnaise for a plant-based alternative.
Cucumber: English cucumbers have fewer seeds and a thinner skin, making them great for this sandwich. If you can’t find them, any cucumber will work. Just peel if the skin is tough.
Bread: Whole wheat or multi-grain bread adds a nice nutty flavor. If you prefer gluten-free, any gluten-free bread will do the trick!
How Do I Ensure My Tuna Mixture is Creamy and Flavorful?
To make a tasty tuna mixture, it’s all about balancing flavors and textures. Start with your drained tuna and really mix in that mayo until it’s smooth and creamy. You want it to hold together without being too runny.
- Chop your celery and green onion finely. This helps distribute their crunchiness throughout the mixture.
- Add lemon juice to brighten up the flavor—this also helps cut through the creaminess of the mayo.
- Don’t forget to taste and adjust the seasoning with salt and pepper. A pinch can make all the difference!
Mix until everything is well combined, and you’ll have a deliciously creamy filling!

Step-by-Step Instructions:
1. Prepare the Tuna Mixture:
Start by opening the can of tuna. Drain the water completely and place the tuna in a medium bowl. Add in the mayonnaise, chopped celery, green onion, and lemon juice. Mix everything together with a fork until it’s well combined. You want it to be creamy but not too runny!

Now, add salt and pepper to the mixture. Taste it to make sure it has the right flavor for you. You can always add a bit more lemon juice if you like it zesty!
3. Assemble the Sandwich:
Lay out your slices of bread. Take two slices and evenly spread the tuna mixture onto each slice. Don’t be shy—load it up! Next, layer the thin cucumber slices on top of the tuna mixture to add a lovely crunch.
4. Finish It Off:
Top each sandwich with the remaining slices of bread. Press down gently to hold everything in place. If you want, you can slice the sandwiches in half for easier eating!

If you’re feeling fancy, sprinkle some fresh dill or parsley on top for garnish. You can serve the sandwiches right away or wrap them up and chill in the fridge for a bit. Enjoy your refreshing and tasty Cucumber Tuna Sandwich!
Can I Use Fresh Tuna Instead of Canned?
Absolutely! If using fresh tuna, you can grill or sear it first, then flake it for the sandwich. Make sure to season it well to enhance the flavor!
How Long Can I Store Leftover Tuna Mixture?
You can store any leftover tuna mixture in an airtight container in the fridge for up to 2 days. Just give it a good stir before using it again, as the ingredients might separate over time.
Is It Possible to Make This Sandwich Gluten-Free?
Yes, simply substitute the whole wheat or multi-grain bread with your favorite gluten-free bread. There are many delicious options available that work just as well!
Can I Add Other Ingredients to the Tuna Mixture?
Definitely! Feel free to mix in diced pickles, capers, or even a dash of hot sauce for some extra flavor. Customize it to suit your taste!
