From the roundup: 24 Easy School Snack Recipes Kids Will Actually Eat
Tuna salad cucumber boats have become my go-to when I need something protein-heavy on the table fast and I cannot face another sandwich. The whole thing takes about 15 minutes, most of which is just draining the tuna and dicing the celery. There is no cooking at all.
The one step that actually matters here is getting the tuna as dry as possible before you mix it. I learned this the hard way after packing these for my kids and pulling out a soggy container at noon. Now I press the drained tuna between two paper towels for a full minute, and the boats hold up until lunch without turning into a puddle.
This recipe makes four servings, which in my house covers two kids for an afternoon snack with a little left over. If you are feeding a crowd or meal-prepping for the week, the tuna salad doubles easily. Just fill the cucumbers the morning you plan to eat them.
Why you will love this
- Ready in 15 minutes flat with zero cooking, just draining, mixing, and scooping
- Two cans of albacore give you a filling snack that actually holds until the next meal
- The tuna salad keeps for two days in the fridge, so you can mix it Sunday and fill boats as needed
- No special ingredients: canned tuna, mayo, celery, and a lemon are probably already in your kitchen
- Naturally gluten-free and low in carbs without any substitutions or special products
Tips for success
- Drain the tuna twice. Open the can, drain it, then press the tuna firmly between two paper towels before it goes in the bowl. Skipping this step is the number one reason the boats go watery.
- Do not scoop the cucumber channel too deep. A shallow pass with a small spoon is enough. If you go too far down, the boat walls get thin and the whole thing buckles when you try to pick it up.
- Taste the tuna salad before filling. Albacore varies by brand, and some cans need more lemon or a pinch of extra salt to taste bright rather than flat.
- Line your storage container with a paper towel. Even well-drained tuna releases a little moisture as it sits, and the paper towel keeps the cucumber from sitting in liquid overnight.
If your boats turn out watery
- The most likely cause is under-drained tuna. Next time, press it between paper towels and let it sit for a full minute before mixing.
- Cucumbers also release water as they sit. If you are prepping ahead, fill the boats the morning of rather than the night before.
- If the assembled boats have liquid in the container, just tip them gently onto a fresh paper towel before serving. The filling is fine.
- Mixing Greek yogurt into the tuna instead of all mayo can actually help here because yogurt is thicker and holds together better over time.
Substitutions
If someone in your house will not touch tuna, canned salmon or finely shredded rotisserie chicken works in the same amounts and mixes the same way. For a mayo swap, plain Greek yogurt is a straight one-for-one substitute and adds a little tang that works well with the lemon. Diced dill pickle can replace the celery if your kids prefer a brinier flavor, and it adds a little crunch without changing the prep at all.
If mini cucumbers are not available, a regular English cucumber cut into shorter four-inch sections works fine. The boats are a little wider and harder to pack neatly, but the flavor is identical.
Make-ahead and storage
Mix the tuna salad up to two days ahead and store it covered in the refrigerator. Hollow out the cucumbers and fill them the morning you plan to eat them. Assembled boats keep for up to two days in a flat airtight container lined with a paper towel, stored in a single layer so they do not tip and spill.
Do not freeze assembled boats. The cucumber becomes soft and watery once thawed and is not worth eating. The tuna salad on its own also does not freeze well because the mayo separates. Keep everything refrigerated and use within two days for the best texture.
Tuna Salad Cucumber Boats
Ingredients
Equipment
Method
- Open the cans of tuna and drain them thoroughly. Press the tuna against the inside of a fine-mesh strainer or press it between two paper towels to get as much water out as possible. Excess moisture is the main reason cucumber boats turn soggy, so take an extra minute here.
- Place the drained tuna in a small mixing bowl and break up any large chunks with a fork. Add the mayonnaise, diced celery, lemon juice, salt, and pepper. Stir everything together until the mixture is evenly combined. Taste it and add a little more salt or lemon if it needs brightness.
- Rinse the mini cucumbers and pat them dry. Slice each one in half lengthwise so you have two long halves. Use a small spoon or melon baller to scoop out the seeds and a little of the flesh down the center, making a shallow channel. Do not scoop too deep or the boat will collapse.
- Spoon the tuna salad into each cucumber boat, filling the channel generously. Use the back of the spoon to press the filling in lightly so it stays put during packing or transport.
- Serve right away or transfer to a flat airtight container lined with a paper towel. Refrigerate until ready to eat. If you are packing these for school, place them in a single layer in the container so they do not stack and tip.
