How to Make Avocado Tuna Salad Boats Step by Step
Mix the Tuna Filling
In a mixing bowl, combine the drained tuna, chopped bell peppers, green onions, black pepper, cilantro, red pepper flakes, Dijon mustard, mayonnaise, and a squeeze of lemon juice. Stir everything together gently until well combined, being careful not to turn the tuna into a paste.
Chill the Mixture
Place the bowl in the refrigerator until you are ready to serve. This short chill time allows the flavors to meld together for a more cohesive salad.
Prepare the Boats
Cut your avocados in half and remove the pits. Scoop a generous amount of the prepared tuna salad into each avocado half, mounding it in the center.
Finish and Serve
Top each boat with an extra pinch of red pepper flakes and a light squeeze of fresh lemon juice if desired. Eat immediately with a spoon while the avocado is fresh.
My Best Tips for Avocado Tuna Salad Boats
- Make sure the tuna is well-drained so the salad stays creamy rather than watery.
- If your avocados are slightly underripe, let them sit at room temperature for a day before using; they should be soft to the touch.
- Store the tuna mixture and the avocados separately if you aren’t eating them immediately, as the avocado will brown once sliced.
- Taste the mixture before adding the final lemon juice to adjust the seasoning to your preference.
How to Store Avocado Tuna Salad Boats for Meal Prep
The tuna salad base keeps well in an airtight container in the refrigerator for up to 3 days. We do not recommend freezing this recipe. For the freshest result, wait to cut and fill the avocado boats until just before you are ready to serve.
