Ingredients Needed To Make This Avocado Tuna Salad

This recipe uses a handful of simple ingredients that you may already have in the refrigerator or pantry! To see the full measurements, scroll down to the recipe card.

  • Red onion – A small red onion, diced, adds flavor, color, and crunch. 
  • Tuna – One can of tuna, drained, works well in this salad. You can use water or oil-based tuna, whatever you prefer. Light tuna is also good as is white albacore tuna.
  • Avocados – Diced, ripe avocados add a nice creamy texture. 
  • Celery – Diced celery adds some crunch to the salad.
  • Peppers – Any kind of peppers, diced, also add some crunch and color.
  • Cilantro – Chopped cilantro adds a pop of green and great flavor. If you aren’t a fan of cilantro you can use parsley.
  • Olive oil – I like to use extra virgin olive oil to help blend the ingredients. 
  • Lemon juice– Fresh lemon juice adds a nice tang to this recipe for avocado tuna salad. If you’re out of lemons use fresh lime juice instead. 
  •  Salt & pepper  – Add salt and pepper to taste

How To Prepare This Avocado Tuna Salad Recipe

First: Place the olive oil, lemon juice, salt, and pepper in a large bowl; salad or mixing bowls are both good options. Use a fork to combine well. 

Second: Add the rest of the ingredients for the salad and toss to combine and coat thoroughly.

Third: Enjoy this avocado and tuna salad on its own, on a bed of greens, in a tortilla, or make an avocado tuna salad sandwich.

Why does restaurant tuna salad taste better? If you find restaurant tuna salad tastes better than homemade it could be because it had some time to sit and the flavors had time to blend. 

 Substitutions and Variations

  • Add hard-boiled eggs for avocado tuna egg salad.

  • Mix in some diced jalapeno peppers or sprinkle with red chili flakes for some spice.

  • Use diced cucumber instead of celery.

  • Serve the tuna avocado salad on lettuce and make lettuce wraps or lettuce cups. Any kind of lettuce will work but romaine lettuce is especially good as it has long leaves. 

  • Chop up red bell pepper and mix it in for added color and crunch. 

  • Stir in a touch of Dijon mustard for a deeper flavor.

  • Up the crunchiness and throw in chopped dill pickles

  • Substitute canned or fresh chicken and make avocado chicken salad. 


Tips & Tricks

  • Make sure to buy the avocados a few days in advance so they have time to ripen as it’s often difficult to buy a ripe avocado. 

  • Only use the avocados if they are just a touch soft when you squeeze them.

  • Avocados will turn brown when exposed to air but they are still safe to eat. 

  • Let the salad sit for a bit to allow the flavors to mingle and develop.

  • Canned tuna is best for this salad, I don’t recommend using fresh. 

  • Serve the salad as a dip with your favorite tortilla chips. 

  • For a more lemony flavor add fresh lemon zest.
