Step‑by‑Step Instructions for Tuna Cucumber Boats

Step 1: Prepare Cucumber
First, wash the cucumbers thoroughly under cool running water. Carefully slice them in half lengthwise using a sharp knife, then scoop out the seeds gently with a spoon, creating a boat shape. Aim for a depth of about half an inch to hold the filling without breaking the cucumber. Set the hollowed-out cucumber halves aside on a serving platter.

Step 2: Mix Tuna Filling
In a medium mixing bowl, combine the canned tuna, mayonnaise, mustard, and diced celery. Use a fork to thoroughly mix the ingredients until well-blended and creamy. This mixture should be cohesive and slightly chunky for a satisfying texture. Taste and adjust seasoning with salt and pepper, making the filling flavorful and balanced.

Step 3: Assemble Boats
Next, take the prepared cucumber halves and spoon the tuna mixture into each boat carefully. Fill them generously but avoid overfilling to prevent spillage. For an appealing presentation, pack the filling lightly. Arrange the filled Tuna Cucumber Boats on a serving tray, ready to serve immediately for that perfect crunchy bite.

Step 4: Serve and Enjoy
Once assembled, serve the Tuna Cucumber Boats right away to enjoy their crisp texture. If desired, garnish with freshly chopped herbs like dill or parsley for added color and flavor. These delightful appetizers are perfect for picnics or light meals, showcasing the vibrant flavors and textures of fresh produce and creamy tuna salad.
