Ingredients
For the Tuna Salad
2 cans (5 oz / 142 g each) tuna in water, drained
⅓ cup mayonnaise
¼ cup red onion, finely chopped
¼ cup celery, finely diced
1 tablespoon fresh lemon juice
1 teaspoon Dijon mustard (optional)
1 tablespoon fresh dill, finely chopped
¼ teaspoon garlic powder
¼ teaspoon black pepper
½ teaspoon salt, or to taste
1 tablespoon chopped fresh parsley (optional)
For the Cucumber Bites
2 large English cucumbers
1 teaspoon fresh dill, for garnish
1 tablespoon chopped parsley, for garnish
A little freshly ground black pepper
Lemon zest (optional)
Instructions
Step 1: Prepare the Cucumbers
Wash the cucumbers thoroughly and pat them dry. Cut them into thick, even rounds, approximately ½ inch thick. Arrange the slices on a paper towel-lined plate to absorb excess moisture. This helps keep the cucumber bites crisp and prevents the tuna salad from sliding off.
Step 2: Drain the Tuna
Open the tuna cans and drain them thoroughly. Press gently with a fork to remove excess liquid. Transfer the tuna to a medium-sized mixing bowl and flake it with a fork into small pieces.
Step 3: Add the Vegetables
Add the finely chopped red onion and diced celery to the tuna. These ingredients provide a delicious crunch and a fresh, slightly sweet flavor that complements the creamy tuna.
Step 4: Make the Creamy Dressing
Add mayonnaise, fresh lemon juice, Dijon mustard, fresh dill, garlic powder, black pepper, and salt to the tuna mixture. Stir everything together until the ingredients are evenly combined and the tuna is creamy.
Add the chopped parsley if desired. Taste and adjust the seasoning, lemon juice, or mayonnaise according to your preference.
Step 5: Chill the Tuna Salad
Cover the tuna salad and refrigerate for 10–15 minutes if time allows. Chilling helps the flavors blend together and makes the mixture easier to spoon onto the cucumber slices.
Step 6: Assemble the Cucumber Bites
Arrange the cucumber rounds on a large serving platter. Spoon approximately 1 tablespoon of tuna salad onto each cucumber slice, adjusting the amount to fit the size of the rounds.
Gently press the tuna salad into a small mound so it stays in place.
Step 7: Garnish and Serve
Sprinkle the cucumber bites with fresh dill, chopped parsley, freshly ground black pepper, or a little lemon zest. Serve immediately while the cucumbers are fresh and crunchy.
Cooking Tips
Choose firm cucumbers: English cucumbers are ideal because they have fewer seeds and a crisp texture.
Drain tuna thoroughly: Removing excess liquid helps prevent watery tuna salad.
Pat cucumbers dry: This helps the tuna topping stay in place.
Adjust the creaminess: Add a little more mayonnaise if you prefer a softer, creamier tuna salad.
Add extra flavor: A teaspoon of pickle relish or a few finely chopped pickles can add a tangy twist.
Keep them crunchy: Assemble the cucumber bites shortly before serving to prevent the cucumbers from releasing moisture.
Make them spicy: Add a pinch of cayenne pepper or a few drops of hot sauce to the tuna mixture.
Serving Suggestions
Serve as a healthy afternoon snack.
Arrange on a party appetizer platter with cherry tomatoes and olives.
Pair with a fresh green salad for a light lunch.
Serve alongside vegetable soup or roasted vegetables.
Enjoy as a low-carbohydrate alternative to tuna sandwiches.
Add avocado slices or a little crumbled feta for extra flavor.
Storage Instructions
Tuna salad: Store in an airtight container in the refrigerator at 40°F (4°C) or below for up to 3–4 days.
Sliced cucumbers: Keep separately in an airtight container in the refrigerator and use within 1–2 days for the best texture.
Assembled cucumber bites: Refrigerate promptly and consume within 1–2 hours for the best crunch and quality, keeping them chilled when serving.
Freezing: Freezing is not recommended because mayonnaise can separate and cucumbers become watery.

Frequently Asked Questions
1. Can I make tuna salad cucumber bites ahead of time?
Yes. You can prepare the tuna salad up to 1 day ahead and store it in an airtight container in the refrigerator. Slice the cucumbers and assemble the bites shortly before serving to keep them crisp.
2. Can I use tuna in oil instead of tuna in water?
Absolutely! Tuna packed in olive oil provides a richer flavor. Drain it thoroughly before mixing with the other ingredients, and consider reducing the mayonnaise slightly.
3. How can I make these cucumber bites healthier?
You can replace some or all of the mayonnaise with plain Greek yogurt. This increases the protein content and reduces the fat, while keeping the tuna salad creamy.
4. Can I use another herb instead of dill?
Yes. Fresh parsley, chives, or cilantro can be used instead of dill. Each herb gives the tuna salad a slightly different flavor.
5. Are tuna salad cucumber bites suitable for meal prep?
Yes. Store the tuna salad and cucumber slices separately in the refrigerator, then assemble individual portions shortly before eating. This helps maintain their freshness and crunch.
