Avocado Tuna Salad Boats are the ultimate solution for a quick, high protein lunch that requires absolutely no cooking. I love making these on busy weekdays when I need something satisfying but do not have the time to turn on the stove. It is a simple meal that feels fancy enough for guests yet easy enough for a solo lunch.
My family enjoys this recipe because it hits that perfect spot between healthy and delicious. The creamy avocado pairs beautifully with the crunchy celery and savory tuna mixture. These boats are naturally gluten free and low carb, making them a great option for almost anyone at your table. If you enjoy meals like my High Protein Cajun Chicken Rice, you will love how filling this lighter option is.

Ingredients for Avocado Tuna Salad Boats
I always keep high quality canned tuna in my pantry for this recipe. It makes a huge difference in the final flavor.
- Two 5-ounce cans tuna in water, drained
- 1/4 cup mayonnaise
- 1 tablespoon Dijon mustard
- 1 celery stalk, finely diced – I recommend dicing this small for better texture
- 2 tablespoons red onion, finely diced
- 1 tablespoon fresh lemon juice
- 1 tablespoon chopped fresh parsley
- Salt and black pepper, to taste
- 2 large ripe avocados – Pro tip: choose avocados that yield slightly to pressure but are not mushy
- 1 teaspoon olive oil, optional for drizzling
- Paprika or chili flakes, optional for garnish

Step-by-Step Instructions
In my experience, mixing the tuna salad first lets the flavors meld while you prep the avocados.
Step 1: In a medium mixing bowl, combine the drained tuna, mayonnaise, Dijon mustard, diced celery, diced red onion, lemon juice, parsley, salt, and black pepper. Stir everything thoroughly until the mixture is creamy and well blended.
Step 2: Halve the avocados lengthwise and remove the pits carefully. If the cavity seems small, scoop out a small amount of flesh to make more room for the filling. You can chop the extra flesh and add it to the tuna mix if you like.
Step 3: Spoon the tuna salad evenly into the prepared avocado halves. I usually mound the filling slightly high for a hearty portion.
Step 4: Drizzle each filled avocado half with olive oil if desired, and sprinkle with paprika or chili flakes for a pop of color. Serve immediately while the avocado is fresh.
What to Serve with Avocado Tuna Salad Boats
These boats are filling on their own, but the right side dish turns them into a complete meal.
Crispy Salmon Bowls: If you are a seafood lover, you might enjoy these boats alongside my Crispy Salmon Bowls for a double dose of healthy fats and protein.
Simple Mac and Cheese: A small portion of Simple Mac and Cheese adds a comforting, warm element that contrasts nicely with the cool and creamy tuna salad.
Broccoli Cheddar Soup: Pairing this light salad with a cup of Broccoli Cheddar Soup creates a satisfying lunch combination that is both hearty and healthy.
Texas Roadhouse Seasoned Rice: You can serve the tuna salad over a bed of Texas Roadhouse Seasoned Rice for a more filling dinner option that absorbs the delicious flavors.
Green Bean Casserole: For a family dinner, Green Bean Casserole works as a warm vegetable side that complements the cold salad perfectly.

Storage and Serving Tips
Store the tuna salad in an airtight container in the refrigerator for up to 3 days. I recommend prepping the avocados fresh right before serving to prevent browning. If you have leftover filled boats, wrap them tightly with plastic wrap pressing it directly against the flesh to minimize air exposure.
FAQs
Can I use tuna packed in oil instead of water?
Yes, tuna packed in oil adds a richer flavor. Just drain it well before mixing so the salad does not become too oily.
How do I keep the avocados from turning brown?
Rub the cut surfaces with a little lemon juice. This helps slow down the oxidation process if you are not serving them immediately.
Is this recipe keto friendly?
Yes, this recipe is low in carbs and high in healthy fats, making it an excellent choice for a keto diet.
