This Cucumber Tuna Sandwich is a refreshing delight! It combines cool, crunchy cucumber with tasty tuna, all nestled between your favorite bread.
Perfect for a quick lunch or snack, it’s light and satisfying. I love adding a sprinkle of salt and pepper for extra flavor—easy peasy and oh so yummy!
Key Ingredients & Substitutions
Tuna: Canned tuna is a quick protein source. I prefer using chunk light tuna for its mild taste, but you can opt for albacore for a firmer texture. If you’re vegetarian, chickpeas or tofu work well as a substitute!
Mayonnaise: While mayo adds creaminess, you can use Greek yogurt for a healthier twist! It gives a tangy flavor and is lower in calories. If you want a dairy-free option, try avocado or a vegan mayo.
Cucumber: Fresh cucumber provides crunch and brightness. If you’re in a pinch, radishes give a similar crunch. Pickles can also add a zingy flavor if you want to switch things up!
Bread: Whole wheat bread is nutritious, but feel free to use sourdough, rye, or gluten-free bread based on your taste and needs. Toasting your bread can add an extra layer of flavor.
How Do I Make the Tuna Mixture Creamy and Flavorful?
Getting the right consistency and flavor for your tuna mixture is essential. Here’s how you can do it:
- Drain your tuna thoroughly to avoid a soggy sandwich, then mash it lightly in a bowl with a fork.
- Add mayonnaise slowly, adjusting to your preferred creaminess. Start with less; you can always add more!
- Mix in chopped celery and red onion for crunch and flavor. If you want a bit of zest, a squeeze of lemon juice works wonders.
- Season with salt and pepper to enhance the flavors, and don’t forget to taste as you go!

How Much Time Will You Need?
This recipe takes about 10 minutes of prep time. It’s quick and easy—perfect for busy days when you want something light and delicious without spending too much time in the kitchen!
Step-by-Step Instructions:
1. Prepare the Tuna Mixture:
Start by draining the can of tuna. Place it into a mixing bowl. Add the mayonnaise, finely chopped celery, and red onion. Use a fork to mix everything together gently until well combined. Make sure not to mash the tuna too much; you want to maintain some texture!
2. Season to Taste:
Now it’s time to add some flavor! Sprinkle in salt and pepper to your liking. Give it another gentle stir and taste the mixture to see if it needs any more seasoning.
3. Assemble the Sandwich:
Take two slices of your chosen bread and lay them flat on a clean surface. Spread an even layer of the tuna mixture onto both slices. Don’t be shy—pile it on!
4. Add Cucumber Slices:
On top of the tuna mixture, layer the thinly sliced cucumbers evenly. This adds a refreshing crunch that pairs perfectly with the creamy tuna.
5. Complete Your Sandwiches:
Now, place the remaining two slices of bread on top of the cucumber layer to form two complete sandwiches. If you like, you can press down gently to help everything hold together.
6. Final Touches:
If you’d like, you can cut the sandwiches in half for easier eating. Serve immediately and enjoy your delicious Cucumber Tuna Sandwich!
Can I Use Different Types of Tuna?
Absolutely! While canned tuna in water is common, you can use tuna in olive oil for richer flavor. If you prefer a vegetarian option, consider using chickpeas or mashed tofu as a substitute.
Can I Prepare This Sandwich in Advance?
Yes! You can prepare the tuna mixture a day ahead and store it in the fridge. Just make sure to assemble the sandwich right before serving to keep the bread from getting soggy.
How Do I Store Leftover Sandwiches?
If you have leftovers, wrap them tightly in plastic wrap or store them in an airtight container in the fridge for up to a day. For best flavor, enjoy them the same day you make them!
What Can I Serve with This Sandwich?
This sandwich pairs well with a side of fresh fruit, a simple green salad, or some crispy vegetable chips for a light meal. Enjoy your lunch!
