Ingredients You’ll Need

Cucumber: Acts as the crunchy, refreshing “boat” that holds the filling; English cucumbers are perfect for their minimal seeds.
Canned Tuna: Choose a high-quality tuna in water or olive oil for the best flavor and texture.
Mayonnaise: Adds creaminess and richness to bind the tuna mixture; Greek yogurt can be swapped for a lighter option.
Dijon Mustard: Offers a little tang and depth, making the filling pop with flavor.
Red Onion: Finely diced for a mild sharpness that complements the tuna beautifully.
Celery: Adds an extra crunchy texture to the filling, making every bite exciting.
Lemon Juice: Brightens everything up with a touch of acidity—don’t skip it!
Salt and Pepper: Essential for seasoning and bringing all the flavors together.
Fresh Herbs (Optional): Dill, parsley, or chives can take the flavor to another level if you have them on hand.

Variations

Spicy Kick: Stir in a spoonful of sriracha or diced jalapeños to the tuna mixture for some heat.
Avocado Addition: Mix in diced avocado for an extra creamy, nutrient-packed twist.
Different Proteins: Swap the tuna for cooked, shredded chicken or even salmon if you prefer.
Vegan Version: Use mashed chickpeas instead of tuna and vegan mayo to make plant-based cucumber boats.

How to Make Tuna Cucumber Boats

Step 1: Prepare the Cucumbers

Wash the cucumbers thoroughly. Slice them lengthwise and scoop out the seeds with a spoon to create a little “boat” shape. Pat them dry with a paper towel to avoid any sogginess later.

Step 2: Make the Tuna Filling

In a medium bowl, combine the drained tuna, mayonnaise, Dijon mustard, finely diced red onion, chopped celery, lemon juice, salt, and pepper. Mix until well combined. Taste and adjust seasoning if needed.

Step 3: Assemble the Boats

Generously spoon the tuna mixture into the hollowed-out cucumbers. Pack it in nicely so every bite has plenty of filling.

Step 4: Garnish and Serve

Sprinkle some fresh herbs over the top if you like, and maybe a light crack of black pepper for extra flavor. Serve immediately for the best texture!

Pro Tips for Making the Recipe

Drain the Tuna Well: You want the filling to be creamy, not watery, so press out as much liquid from the tuna as you can.
Use Crisp, Fresh Cucumbers: Softer cucumbers won’t hold up well and could turn soggy quickly.
Chill Before Serving: If you have a few extra minutes, refrigerate the assembled boats for 10–15 minutes to make them even more refreshing.
Adjust to Taste: Don’t be afraid to tweak the filling to your liking—more lemon juice, a dash of hot sauce, or extra herbs can personalize it perfectly.

How to Serve

These Tuna Cucumber Boats are a fantastic light lunch or snack all on their own, but they also pair wonderfully with a few extras:

Light Meal

Serve alongside a simple mixed greens salad or a handful of your favorite crackers for a more complete meal.

Party Appetizer

Cut the cucumber boats into bite-sized pieces and secure them with toothpicks for a fun, healthy party snack.

Picnic Treat

Wrap them individually in parchment paper for a portable, mess-free addition to your picnic basket.

Make Ahead and Storage

Storing Leftovers

Keep any leftover tuna filling in an airtight container in the refrigerator for up to 3 days. Assemble the cucumber boats just before serving for the best texture.

Freezing

Note: Freezing is not recommended, as both the cucumbers and tuna filling will lose their texture when thawed.

Reheating

These are best enjoyed cold, straight from the fridge—no reheating needed!

FAQs

Can I make the tuna filling ahead of time?
Yes! The tuna mixture can be made up to 2 days in advance. Just store it tightly covered in the fridge and fill the cucumbers when you’re ready to eat.

What type of cucumber works best?
English cucumbers are ideal because they have fewer seeds and a thinner skin, but regular cucumbers will work too. Just peel them if the skin is too thick.

Can I add other veggies to the tuna mix?
Absolutely! Finely chopped bell peppers, grated carrots, or even a few peas would add great texture and color to the filling.

Is there a way to make this dairy-free?
Yes! Simply use a dairy-free mayonnaise or a creamy avocado mash instead of regular mayo to keep this recipe dairy-free.
