Each ingredient in this Tuna Avocado Boats Recipe plays a key role — from the creamy, buttery avocados to the tangy tuna filling. These simple yet essential components come together to deliver a dish that’s bursting with texture, taste, and just the right pop of color to make it irresistible.
- 2 ripe avocados: Choose ones that yield slightly to gentle pressure for that perfect creamy texture to cradle the filling.

- 2 tablespoons mayonnaise (or Greek yogurt for a lighter option): Adds smoothness and richness to the tuna mixture.
- 1 teaspoon Dijon mustard: Gives a subtle tang and complexity to brighten up the filling.
- 1 tablespoon lemon juice (freshly squeezed): A fresh burst that lifts all the flavors and prevents the avocado from browning quickly.
- Salt and pepper to taste: Essential seasonings to balance flavor perfectly.
- 2 tablespoons chopped celery: Provides a satisfying crunch and freshness that contrasts beautifully with the soft avocado.
- 1 tablespoon diced red onion: Adds a mild bite and a splash of color.

How to Make Tuna Avocado Boats Recipe
Step 1: Prepare the Avocado
Begin by carefully slicing each avocado in half and gently removing the pit. Use a spoon to scoop out a small portion of the flesh from each half to enlarge the cavity slightly—just enough to hold the tuna filling without losing the delightful avocado creaminess.
Step 2: Make the Tuna Filling
In a bowl, combine your drained tuna with mayonnaise or Greek yogurt, Dijon mustard, fresh lemon juice, salt, and pepper. Stir well until every bit of tuna is lovingly coated in this creamy, tangy mixture. Don’t forget to fold in the finely chopped celery and diced red onion for that perfect balance of crunch and zest.
Step 3: Assemble the Boats
Now comes the fun part! Spoon the tuna mixture generously into each avocado half, packing it in so it stays put while you enjoy. This creates a beautiful presentation that invites you to dive right in.
Step 4: Add Toppings
To elevate your Tuna Avocado Boats Recipe, sprinkle the tops with fresh herbs like dill or parsley. If you’re feeling adventurous, add some sliced olives, diced tomatoes, or a pinch of paprika for a lovely pop of flavor and color that’ll impress any guest or simply brighten your own meal.
How to Serve Tuna Avocado Boats Recipe
Garnishes
Fresh herbs are the classic finish for this dish—dill and parsley add herbal notes that lift the entire flavor profile. You can also experiment with a drizzle of hot sauce, a squeeze of extra lemon, or even some toasted sesame seeds for an exciting twist. Garnishes not only improve taste but also make your presentation irresistible.
Side Dishes
Tuna Avocado Boats pair wonderfully with crisp green salads, crunchy vegetable sticks, or a simple quinoa side to round out your meal with more substance. If you want something lighter, fresh fruit or a handful of nuts are perfect complements that keep the meal balanced and refreshing.
Creative Ways to Present
For a fun party appetizer, try halving cherry tomatoes and stuffing them with the same tuna mix for bite-sized boats. Alternatively, serve the avocado halves on a bed of mixed greens or sliced cucumbers to add color and texture variation. The possibilities are endless when you’re excited about this Tuna Avocado Boats Recipe!
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers, store the tuna filling and avocado halves separately in airtight containers in the fridge. This prevents the avocado from browning and keeps the tuna salad fresh. Combine just before serving to enjoy the best texture and flavor.
Freezing
Freezing avocado is generally not recommended due to texture changes, so avoid freezing the assembled boats. However, the tuna salad can be frozen separately in portions, though it may lose some texture upon thawing. For this reason, it’s best to enjoy this Tuna Avocado Boats Recipe fresh whenever possible.
Reheating
This dish is best served cold or at room temperature, so reheating isn’t typically necessary. If you prefer a warmer filling, gently warm the tuna mix on the stove or microwave before assembling, but skip heating the avocado itself to keep its creamy texture intact.
FAQs
Can I use other types of fish instead of tuna?
Absolutely! While tuna is classic, flaked salmon or canned crab meat make delicious and elegant substitutes. Just keep in mind the seasoning might need slight adjustments to complement these flavors.
How do I keep the avocado from turning brown?
The lemon juice in the filling helps prevent browning, but you can also brush the avocado halves with a bit of lemon or lime juice right after scooping. Storing them tightly covered and refrigerated will slow oxidation as well.
Can I make this recipe vegan?
Yes, by swapping tuna for mashed chickpeas or a plant-based tuna alternative and using vegan mayo or creamy avocado-based dressings, you can enjoy a delicious vegan version of this Tuna Avocado Boats Recipe.
What’s the best way to serve this for a party?
Prepare the tuna mixture ahead but assemble the boats just before serving for optimal freshness and presentation. Arrange them beautifully on a platter garnished with herbs and colorful toppings to wow your guests.
Is this recipe gluten-free?
Yes, Tuna Avocado Boats Recipe is naturally gluten-free as long as you check your mayonnaise and mustard labels to ensure no gluten-containing additives are included.
Final Thoughts
I genuinely hope you give this Tuna Avocado Boats Recipe a try because it’s one of those dishes that feels luxurious yet requires minimal effort. It’s fresh, satisfying, and endlessly adaptable to your taste buds’ desires.

Ingredients
Avocado Boats
- 2 ripe avocados
Tuna Filling
- 1 can (5 oz) tuna, drained (albacore or skipjack)
- 2 tablespoons mayonnaise (or Greek yogurt for a lighter option)
- 1 teaspoon Dijon mustard

- 1 tablespoon diced red onion
Toppings and Garnish
- Fresh herbs (such as dill or parsley for garnish)
- Optional: sliced olives, diced tomatoes, paprika for extra flavor
Instructions
- Prepare the Avocado: Carefully cut each avocado in half and remove the pit. Use a spoon to scoop out a small amount of the flesh to create a slightly larger cavity for the filling, but don’t scoop out too much to maintain the boat shape.
- Make the Tuna Filling: In a mixing bowl, combine the drained tuna, mayonnaise, Dijon mustard, lemon juice, salt, and pepper. Add chopped celery and diced red onion for crunch and flavor. Mix well until all ingredients are evenly coated.
- Assemble the Boats: Generously fill each avocado half with the tuna mixture. Pack the filling carefully to prevent it from falling out and ensure each bite has a perfect balance of avocado and tuna salad.
- Add Toppings: Enhance flavor and presentation by topping the tuna-filled avocados with fresh herbs such as dill or parsley. Optionally, add sliced olives, diced tomatoes, or a sprinkle of paprika for added texture and taste.
Notes
- Use Greek yogurt instead of mayonnaise for a healthier, lighter option.
- Chilling the tuna salad before assembling can enhance flavor and texture.
- Add a squeeze of extra lemon juice over the assembled boats to prevent browning of the avocado.
- For extra crunch, consider adding chopped cucumber or bell peppers.
- This dish is best served fresh but can be stored in the fridge for up to 1 day.
