Hello, everyone.
I hope you all are doing well. How was your weekend? I hope you can enjoy the nice weather. This past weekend was the first time that we had really nice spring weather. It was very sunny, bright and beautiful. Of course, we had to enjoy it because living in Canada it is not every day that you have awesome weather like that.
It was a very good weekend to have my cousin who lives in Boston visit us here in Toronto. She came to meet my little 2-month-old baby boy Thomas for the first time. We spent a lot of time outside walking around the city. I found out that our little boy loves to be outside. We were out for about 5-6 hours and he was absolutely awesome. He didn’t cry a single time. I guess he was amazed by the amount of people he met at once and by all the different things he could see in the city.
Speaking of great weather… The recipe I am sharing today is perfect to have outside on your patio during the weekend for a simple appetizer or light dinner. Why? Because it is fresh, light, and delicious. On top of that, these Avocado Tuna Boats only take 10 minutes to be ready and they are so easy to make. They’re like my 5-Ingredient Chicken Zucchini Boats but with tuna!
This gluten-free and dairy-free recipe is made with just a few ingredients such as red onions, avocado, tuna, and a little bit of mayo. This is so yummy. I used a can of tuna because it is the faster and cheaper option, but you use a real piece of fresh tuna. You just need to cook the tuna before or you can use leftovers. If you make it with canned tuna, choose a good quality tuna meat that comes packed with salt and olive oil or water.
This Avocado Tuna Boat recipe is very versatile since you can always change it up by adding other ingredients like tomatoes, cucumbers, and bell peppers. You can even change it up and use the ingredients to make this Super Easy Avocado Cucumber Tuna Salad. You just need to use your creativity. Enjoy!

Ingredients
- 4 medium ripe avocados peeled and halved
- 1/2 cup mayonnaise
- 2 tablespoons lemon juice
- 2 cans tuna meat drained
- ½ cup red onions chopped
- 1/4 teaspoon crushed red pepper
- 1/2 cup shredded mozzarella cheese
- 1/2 teaspoon paprika
- 1 tablespoon chopped fresh parsley divided
Instructions
- Preheat broiler.
- Add four avocado halves in a bowl and mash with a fork.
- Add mayonnaise, lemon juice, tuna, red onions, crushed red pepper and mix to combine well.
- Spoon the avocado mixture into avocado halves.
- Transfer to a baking sheet.
- Sprinkle with cheese and paprika. Broil from heat for 3-5 minutes or until cheese is melted.
- Garnish with fresh parsley.
Tips
- You can use tuna packed in oil or water. Just make sure to fully drain it.
- Make sure you chop everything finely so they all fit into the avocado.
- I like using full-fat mayo but you can use light mayo as well.
- To store: I don't recommend storing this for long as the avocados will brown. Store for up to a day in the fridge in an airtight container.

We were disappointed to see that this recipe states “dairy-free”, yet it calls for mozzarella cheese.
