Ingredients

  • Tuna: canned water packed reliable protein source select a brand with dolphin safe labeling and firm flakes
  • Mayonnaise: creamy texture and richness choose a good-quality mayo with few additives
  • Dijon mustard: subtle tang and savory note look for one with smooth consistency
  • Celery: finely diced for crunch and freshness if possible pick celery with crisp stalks and bright green color
  • Red onion: a sweet sharpness and color use fresh firm onions for best flavor
  • Fresh lemon juice: adds acidity to brighten the entire salad always use freshly squeezed for best results
  • Fresh parsley: herbaceous lift and flecks of color choose flat-leaf parsley and chop just before using
  • Salt and black pepper: essential seasoning opt for freshly ground black pepper for extra zing
  • Ripe avocados: buttery bowl for the salad test for ripeness by gently pressing the skin it should yield slightly
  • Olive oil: a finishing drizzle to add richness optional extra use high-quality extra virgin olive oil
  • Paprika or chili flakes: a dusting for gentle heat and color optional pick smoked paprika for more depth

Instructions

Prepare the Tuna Salad:
In a medium mixing bowl combine the drained tuna mayonnaise Dijon mustard celery red onion lemon juice parsley salt and black pepper. Mash and stir everything together vigorously until the mixture becomes creamy and evenly blended with no dry tuna pieces left.
Prepare the Avocado Boats:
Set your cutting board and use a sharp knife to slice each avocado in half lengthwise. Gently twist the halves apart and carefully remove the pit. If the cavity seems too small use a spoon to scoop out a little of the flesh making room for the filling. Reserve any extra avocado for snack or mix it into the tuna salad for extra creaminess.
Fill the Avocado Boats:
Use a spoon to evenly mound the tuna salad into the hollow of each avocado half. Gently press the filling in to ensure each boat is generously filled and the tuna does not spill out.
Add Finishing Touches:
If desired give each avocado boat a light drizzle of olive oil. Sprinkle with paprika or chili flakes for extra flavor and a pop of color.
Serve and Enjoy:
Arrange the avocado tuna salad boats on a platter or individual plates. Enjoy them immediately either chilled or at room temperature for best texture and taste.

I never get tired of the creamy avocado paired with the bright flavors of lemon and parsley. My youngest loves to help scoop and fill the avocado halves which turns making lunch into a mini family activity every time.

Storage Tips

This dish is best eaten fresh because avocados can brown quickly but you can prep the tuna salad up to one day ahead and keep it in an airtight container in the fridge. Only assemble with avocados right before serving to maintain the freshest flavor and texture. If storing leftovers cover avocado halves tightly with plastic wrap pressing it directly against the surface to limit browning. If preparing for packed lunches add a little extra lemon juice to the avocado to prevent oxidation.

Ingredient Substitutions

If you want to lighten up the salad swap some or all of the mayonnaise for Greek yogurt and adjust the salt to taste. Add diced pickles or capers for a briny pop if you like more tang. Sunflower seeds or pumpkin seeds make a great crunchy topping especially if you want to keep it nut free. Serve on halved tomatoes or scooped cucumbers instead of avocado if avocados are not available.

Serving Suggestions

Serve the tuna salad boats as a light lunch with a fresh green salad on the side. For parties display them on a platter and garnish with extra parsley or colorful microgreens for an impressive appetizer. You can also scoop the filling onto mini bell pepper halves or endive leaves for a pretty gluten free option. My favorite is to tuck them alongside a handful of seed crackers for some crunch.

Cultural and Seasonal Notes

Avocado tuna boats are a modern spin on classic tuna salad inspired by American deli style lunches. They shine brightest in spring and summer when avocados reach peak ripeness and you want refreshing meals. For winter swaps try using baked sweet potatoes as a base. Fresh parsley is easy to find year round but you can substitute cilantro for a different herbal flavor.
