The Cucumber Tuna Sandwich is a refreshing and light meal that’s super easy to make. It’s packed with tasty tuna, crunchy cucumbers, and a bit of creamy mayo, all piled between slices of bread!
This sandwich is perfect for a quick lunch or a snack. I love how the crunchy cucumbers make every bite feel fresh. It’s a fun way to enjoy tuna without the fuss—easy peasy! 🥪
Key Ingredients & Substitutions
Tuna: For this recipe, canned tuna packed in water works best. If you’re looking for a healthier option, try tuna packed in olive oil. For a vegetarian version, substitute tuna with chickpeas mashed with similar seasonings.
Mayonnaise: Regular mayo adds creaminess, but if you’re watching your calorie intake, use Greek yogurt instead. It gives a nice tangy flavor and is healthier!
Cucumber: Fresh cucumbers add a refreshing crunch, but you can use pickles or sliced avocados if you want something different. Just keep in mind that avocados will add creaminess!
Bread: Whole wheat bread is my favorite for this sandwich, but feel free to use any bread you love. Gluten-free bread is also a great substitute if that’s what you need!
How Do I Make a Creamy Tuna Mixture?
Making the perfect tuna salad for your sandwich is all about mixing until smooth but not overdoing it. Start by adding mayo and other ingredients to the tuna in a bowl.
- Drain the tuna well to avoid a soggy sandwich.
- Combine it with mayo, celery, lemon juice, and green onions.
- Add salt and pepper to taste, and mix until it’s well blended but still slightly chunky for texture.
Remember, you can adjust the mayo and lemon juice to get your desired creaminess and flavor! Enjoy crafting this delightful sandwich! 🥪

Delicious Cucumber Tuna Sandwich Recipe
Ingredients You’ll Need:
- 1 can (5 oz) tuna in water, drained
- 2 tablespoons mayonnaise
- 1 tablespoon finely chopped celery
- 1 teaspoon lemon juice
- Salt and pepper, to taste

How Much Time Will You Need?
This delightful Cucumber Tuna Sandwich takes about 10 minutes to prepare with all the mixing and assembling. If you decide to let it chill for a bit, you might want to add another 15-30 minutes for a refreshing taste!
Step-by-Step Instructions:
1. Prepare the Tuna Mixture:
Start by draining the tuna well to get rid of excess water. In a medium bowl, combine the drained tuna, mayonnaise, chopped celery, lemon juice, and green onion. Mix everything together until it’s well combined and creamy.
2. Season as You Like:
Now, add salt and pepper to taste. If you prefer a little more tang, feel free to add more lemon juice or mayo for creaminess. Taste as you go to find that perfect balance!
3. Butter the Bread (Optional):
If you want a bit more flavor, lightly butter one side of each bread slice. This step is optional, but it can add a lovely richness to your sandwich!
4. Assemble Your Sandwich:
Spread an even layer of the tuna mixture over two of the bread slices (on the side that’s not buttered, if you chose to butter them). Make sure it’s nice and thick so every bite is packed with flavor!
5. Add Cucumber Slices:
Layer the thin cucumber slices on top of the tuna mixture. The cucumbers add a lovely crunch and freshness to the sandwich.
6. Top and Close:
Take the other two slices of bread and place them on top, buttered side up if you used butter. Gently press down to help everything stick together.
7. Garnish and Serve:
If you’d like, you can garnish the sandwiches with small sprigs of fresh dill for a pop of color and flavor. This step is purely for aesthetic appeal, but it makes your sandwich look fancy!
8. Cut and Enjoy:
Carefully cut the sandwiches in half and serve right away. If you need to save some for later, wrap them up and chill them in the fridge for a cool, tasty treat later on.
Enjoy your delicious Cucumber Tuna Sandwich, perfect for a quick lunch or a delightful snack anytime! 🥪
Can I Use Fresh Tuna Instead of Canned?
Yes, fresh tuna can be used. You can grill or sear the tuna quickly, then flake it once cooked. Just ensure it’s properly seasoned and cooled before mixing it with the other ingredients.
How Can I Make This Sandwich Gluten-Free?
To make a gluten-free version, simply use gluten-free bread. There are many great options available now that have similar taste and texture to regular bread!
Can I Prepare This Sandwich in Advance?
Absolutely! You can prepare the tuna mixture ahead of time and store it in an airtight container in the fridge for up to two days. Assemble the sandwich just before serving to keep the bread fresh.
What Vegetable Can I Add for Extra Crunch?
If you want to mix things up, consider adding shredded carrots, thinly sliced bell peppers, or even radishes for an added crunch and flavor boost! They’re all great complements to the tuna and cucumber.
