Storage/Reheating

FAQs

Can I make Lemon Dill Tuna Salad in advance?

Yes, the tuna salad can be prepared up to 2 days in advance. Store it in the refrigerator and assemble the sandwiches just before serving for the freshest results.

What kind of croissants work best?

Fresh, bakery-style croissants are ideal for their flaky texture and buttery flavor. Store-bought versions will work too but may be slightly less airy.

Can I use dried dill instead of fresh?

Fresh dill is preferred for its vibrant flavor, but if using dried, reduce the amount to 2 teaspoons and let the salad sit for 10 minutes to allow the flavors to develop.

How do I make it healthier?

Use light mayonnaise or Greek yogurt, and serve the tuna salad in lettuce wraps or on whole wheat bread instead of croissants.

Can I add cheese to the sandwich?

Yes, a thin slice of Swiss, Havarti, or provolone can add a creamy, mild richness to the sandwich.

What side dishes pair well with this?

These sandwiches go great with kettle chips, a crisp green salad, fresh fruit, or a simple soup like tomato basil or vegetable.

Can I freeze tuna salad?

No, freezing tuna salad is not recommended. The mayo will separate and the vegetables will become watery once thawed.

Can I make this recipe dairy-free?

Yes, the base recipe is dairy-free. Just make sure the croissants and mayonnaise used are free of dairy ingredients.

Can I serve the tuna salad on something other than croissants?

Absolutely. It’s delicious on multigrain bread, in wraps, over greens, or scooped onto crackers.

What type of tuna should I use?

Use tuna packed in water for a lighter taste. Flaked tuna mixes easily, and draining it thoroughly prevents a soggy salad.
