Easy Tuna Salad Lettuce Boats are crisp lettuce leaves filled with a creamy tuna salad and a bright, slightly spicy cucumber salsa. They come together quickly, making them a perfect no-cook meal for busy weekdays or a light appetizer for gatherings.
I always keep canned tuna on hand for quick recipes like cucumber tuna rolls, tuna cottage cheese salad, and these lettuce boats. This recipe is one of my favorites when I want something nourishing without turning on the stove: just mix the components, assemble, and serve.
They’re also great as an appetizer or side when you’re entertaining. Customize the fillings to suit your taste and you can have these ready in 20 minutes or less.
Recipe Tip
Combine the tuna salad and cucumber salsa to serve as a dip—perfect with chips or raw vegetables.
Tuna Salad Lettuce Boat Ingredients
Scroll down to the recipe card for exact measurements and details.
- Lettuce leaves: Gem, butter, or large Romaine leaves—choose firm, crisp leaves that will hold the filling.
- Cucumber: Persian or English cucumbers are ideal because they have fewer seeds and thinner skin.
- Avocado: Use ripe avocados that yield slightly to gentle pressure. Any extra avocado can be used in other snacks or salads.
- Peppers: A mini yellow pepper adds crunch and sweetness; jalapeño provides heat. Adjust the jalapeño amount to suit your spice preference.
- Maple syrup: A touch of sweetness balances the salsa; honey works as a substitute.
- Lemon: Fresh lemon juice brightens the tuna salad and cuts through the mayo.
- Tuna: Use canned tuna packed in water or oil—drain it well. Canned salmon or shredded chicken are good alternatives.
- Mayonnaise: The base for the tuna salad; substitute Greek yogurt for a lighter version.
- Red onion: Finely chopped for crunch and a mild bite.
- Fresh basil: Optional garnish to add a fresh herbal note.
- Sea salt and pepper: To taste.
How to Make Easy Tuna Salad Lettuce Boats
- Prepare the tuna salad: In a bowl, combine drained tuna, mayonnaise, and finely chopped red onion. Add a squeeze of lemon juice, sea salt, and freshly ground black pepper. Taste and adjust seasoning.
- Make the cucumber salsa: Finely dice the cucumber, avocado, mini yellow pepper, and jalapeño (remove seeds if you prefer milder heat). Toss with olive oil, a teaspoon of maple syrup, sea salt, and pepper.
- Assemble the boats: Place a spoonful of cucumber salsa onto each lettuce leaf, then top with a dollop of tuna salad. A small cookie scoop makes portioning quick and tidy.
- Garnish and serve: Add a small lemon wedge or a basil leaf to each boat and serve immediately.
FAQs
Serve them as a light meal, part of an appetizer platter, or as a starter alongside heartier dishes. They pair well with roasted vegetables, a simple soup, or a baked potato dish.
I don’t recommend assembling them in advance since the lettuce can become soggy. You can, however, prepare the tuna salad and cucumber salsa separately and store them in airtight containers in the refrigerator for up to a week. Assemble just before serving.
Choose large, sturdy leaves that can support fillings: gem lettuce, butter lettuce, or Romaine are all great choices.
