• Fresh dill: 2–3 tablespoons, chopped
• Celery: 1–2 ribs, finely diced

Step-by-Step Instructions

1. Prep the lettuce: Gently separate the lettuce leaves. Rinse, pat dry, and chill in the fridge so they stay crisp.
2. Drain the tuna well: Open the cans and press out excess liquid.

   The drier the tuna, the better it will absorb the dressing without getting watery.

3. Chop the vegetables: Finely dice the cucumber and celery. Slice the green onions or mince the red onion. Chop the dill.
4. Mix the dressing: In a bowl, whisk together mayonnaise, Greek yogurt (if using), Dijon, juice of half a lemon, a pinch of lemon zest, a splash of olive oil (optional), and a good pinch of salt and pepper.
5. Combine tuna and veg: Add the drained tuna to a large bowl and flake with a fork.

   Add cucumber, celery, onion, dill, and capers if you like.

6. Toss with dressing: Pour over the dressing and gently fold until everything is evenly coated. Taste and adjust with more lemon, salt, or pepper as needed.
7. Assemble the cups: Spoon the tuna salad into chilled lettuce leaves. Aim for 2–3 tablespoons per cup.
8. Serve: Finish with extra dill, a twist of black pepper, and a squeeze of lemon.

   Enjoy immediately.

How to Store

• Tuna salad: Store in an airtight container in the fridge for up to 3 days. Stir before serving, and refresh with a little lemon juice if needed.
• Lettuce: Keep leaves separate from the tuna. Wrap in a paper towel and store in a zip-top bag or container to keep them crisp.
• Meal prep tip: Pack tuna salad in one container and lettuce leaves in another.

  Assemble just before eating to avoid soggy cups.

Benefits of This Recipe

• High in protein: Tuna keeps you full and supports muscle repair without a lot of calories.
• Hydrating and refreshing: Cucumber and lettuce add water content and crunch without heaviness.
• Omega-3 fats: Tuna offers heart-healthy fats that support brain health.
• Low-carb friendly: Using lettuce cups instead of bread keeps it light and gluten-free.
• Fast and affordable: Pantry tuna plus a few fresh ingredients make this budget-friendly and quick.

Pitfalls to Watch Out For

• Watery tuna salad: Failing to drain the tuna or using too much lemon juice can water it down. Drain well and add lemon gradually.
• Soggy lettuce: Wet or warm leaves wilt fast. Dry thoroughly and chill before filling.
• Over-salting: Capers and Dijon add salt.

  Taste before adding more salt to avoid overseasoning.

• Too much onion: Raw onion can overpower. Start small, then add more to taste.
• Flavors going flat: If it tastes bland, it likely needs more acid. A little extra lemon or a splash of white wine vinegar perks it up.

Recipe Variations

• Mediterranean twist: Add chopped kalamata olives, cherry tomatoes, and a pinch of oregano.

  Swap dill for parsley.

• Crunch lovers: Fold in diced radish or sliced snap peas. Top with toasted almond slivers.
• Lighter dressing: Use half mayo, half Greek yogurt, and add a tiny drizzle of honey to balance the lemon.
• Spicy kick: Stir in a teaspoon of sriracha or a pinch of red pepper flakes, and add extra green onion.
• Avocado-creamy: Mash half an avocado into the dressing and reduce the mayo. Finish with lime instead of lemon and extra dill or cilantro.
• Herb swap: Try chives, tarragon, or parsley if dill isn’t available.

  Each brings a different but tasty vibe.

• Lettuce alternatives: Use endive leaves for bite-sized cups or pile the salad over sliced cucumbers for a fork-free snack.

FAQ

What type of tuna is best for this recipe?

Chunk light or solid albacore tuna packed in water works well. Albacore is firmer and milder; chunk light has a softer texture and stronger flavor. Use what you prefer, but drain it very well.

Can I make this dairy-free?

Yes.

Skip the yogurt and use all mayonnaise, or use a dairy-free yogurt or mayo alternative. The dressing will still be creamy and flavorful.

How far in advance can I make the tuna salad?

You can make it up to 3 days ahead. The flavors meld nicely by day two.

Stir before serving and add a squeeze of lemon to brighten it.

What if I don’t like dill?

Swap in chopped parsley or chives. You’ll still get freshness without the distinct dill flavor.

Can I use canned salmon or chicken instead?

Absolutely. Canned salmon is great with dill and lemon, and canned chicken works too.

Adjust salt and lemon to taste, since each protein has a different flavor profile.

How do I keep the lettuce from tearing?

Choose sturdy leaves like Bibb or little gem, and avoid overfilling. Dry the leaves well and keep them chilled until assembling.

Is this recipe kid-friendly?

Usually yes. If serving to kids, reduce or skip raw onion and capers, and use a little extra mayo for a creamier texture.

What sides go well with these lettuce cups?

Try sliced tomatoes, a small fruit salad, or a handful of kettle chips for crunch.

A simple soup pairs nicely if you want a heartier meal.

Can I freeze tuna salad?

No. Mayo-based salads don’t freeze well. The texture breaks and becomes watery after thawing.

Keep it refrigerated and enjoy within a few days.

How can I make it more filling without bread?

Add diced avocado, chickpeas, or hard-boiled eggs to the salad. You can also serve it alongside quinoa or roasted potatoes.

In Conclusion

Tuna Salad Lettuce Cups with Cucumber and Dill deliver fresh flavor, satisfying crunch, and a creamy finish—all with minimal effort. They’re easy to customize, simple to prep ahead, and light enough for everyday eating.
