- Serving platter
How to Make This Recipe
Step 1 – Prep the Cucumber
Start by washing the cucumber thoroughly. Pat it dry with a clean towel. Use a knife to cut the cucumber lengthwise into two halves. Then, cut each half into two pieces, giving you four cucumber “boats.” Carefully scoop out the seeds from each half to create space for the tuna mixture.
Step 2 – Make the Tuna Salad
In a medium mixing bowl, combine the drained tuna, Greek yogurt, mayonnaise, diced onion, fresh dill, garlic powder, salt, and pepper. Stir all the ingredients together until you achieve a creamy tuna salad. Taste it, and if you feel like it needs a bit more seasoning, add salt and pepper as needed.
Step 3 – Assemble and Serve
Scoop the creamy tuna salad into the prepared cucumber boats. Fill each boat generously, and arrange them on a serving platter. Serve immediately. These boats are best enjoyed fresh, but they can be stored for later!

Tips for Perfect Results
To ensure your Tuna Cucumber Boats turn out perfectly, keep these tips in mind:
- Choose firm, fresh cucumbers for the best crunch.
- Use a can of tuna packed in water for a lighter option.
- Mix the tuna salad ahead of time, but fill the cucumber boats just before serving to keep them crisp.
- Adjust the flavor by adding your favorite spices or herbs.
- Consider serving with lemon wedges for a refreshing touch.
Flavor Variations
For a bit of creativity, here are some variations you can try:
- Add chopped olives for a Mediterranean twist.
- Mix in some diced pickles for added tanginess.
- Toss in diced apples or grapes for a sweet crunch.
- Substitute the tuna with canned chicken for a different flavor profile.
What to Serve With This Recipe
These Tuna Cucumber Boats are great on their own, but you can pair them with additional sides for a complete meal:

- Whole grain crackers
- Veggie sticks and hummus
Storage, Make-Ahead & Leftovers
You can prepare the tuna salad up to a day in advance. Store it in the fridge in an airtight container until you’re ready to use it. The assembled cucumber boats are best eaten fresh, but if you have leftovers, keep them in the fridge for a few hours. Be mindful that cucumbers may become soggy if stored for too long.
