Zusatztipps für die Zubereitung

To ensure your boats stay sturdy, choose firm, large cucumbers. Use a sharp knife for the initial slicing and a metal spoon to neatly remove the seeds. Make sure to drain the tuna thoroughly before mixing to prevent the avocado salad from becoming too watery.

Varianten und Anpassungen

You can easily customize this recipe by swapping the tuna for cooked shredded chicken or mashed chickpeas. For extra crunch, mix in some diced tomatoes or bell peppers. If you prefer a spicier kick, add a few drops of your favorite hot sauce to the dressing.

Serviervorschläge

For the best flavor and texture, serve these boats chilled. They are perfect for a light lunch or as a healthy appetizer. You can garnish the finished boats with an extra sprinkle of fresh herbs and a crack of black pepper just before serving.

Recipe Guide

How long do cucumber boats stay fresh?

These are best served immediately to maintain the crisp texture of the cucumber. If meal prepping, store the filling and cucumber boats separately in airtight containers—filling keeps for 2-3 days refrigerated, while cut cucumbers stay fresh for 1-2 days.

Can I make this dairy-free?

Yes, this dish is naturally dairy-free as written. The creamy texture comes from ripe avocado rather than any dairy products, making it suitable for those avoiding dairy.

What can I substitute for tuna?

Cooked shredded chicken breast, canned salmon, or chickpeas work beautifully as alternatives. Each maintains the protein content while offering slightly different flavors and textures.

How do I prevent the cucumber from getting soggy?

Scoop out the seeds thoroughly to create a hollow boat, and pat the cavity dry with paper towels before filling. For best results, fill just before serving rather than letting them sit too long.

Can I add extra vegetables to the filling?

Absolutely—diced bell peppers, tomatoes, or celery add wonderful crunch and freshness. Just keep pieces small so they fit neatly into the cucumber boats without making them difficult to eat.
