Avocado Tuna Salad is one of my go-to recipes for lunch. It’s quick to make, packed with flavor, and filled with nutritious ingredients. Of course, when you load the tuna salad on a buttery croissant, it becomes a little less healthy. 

I’ll definitely indulge in the croissant sandwich every once in a while, but when I’m looking for a lighter meal, I’ll pack the tuna into a few pieces of lettuce to make a quick lettuce wrap. 

Today I’m sharing how to make this salad, what to eat it with, and sharing a few quick tips. Let’s get started!

How to make Avocado Tuna Salad

  • Add the salad ingredients to a large bowl: Place the drained tuna, diced avocado, minced parsley, diced celery, and diced bread and butter pickles in a large bowl. 
  • Make the dressing: Combine the mashed avocado, mayo, Dijon mustard, lemon juice, olive oil, salt and  pepper. Whisk to combine.
  • Combine: Add the dressing to the salad ingredients. Gently toss to combine and season once more to taste.
  • Serve: Eat the avocado tuna salad as is, in a salad wrap, or on a croissant with lettuce (my personal favorite!).

 Avocado Tuna Salad serving suggestions

On a lettuce wrap 

In a sandwich with some lettuce, tomatoes, and avocado. Use a good, whole-grain bread for a healthier sandwich or a croissant for a more indulgent sandwich.

With a side of fresh fruit or this fruit salad recipe

As a dip with pita chips and fresh veggies

The mayo in this recipe

I highly recommend the small amount of mayonnaise in this avocado tuna salad. You can use an avocado-based mayo or low-fat mayo instead of regular.

If you’re completely opposed to using mayonnaise, replace it with a plain Greek yogurt; it will taste different and tangier.

Quick tips

  • Use good-quality ingredients: They make all the difference in Avocado Tuna Salad. I like a good olive oil-packed tuna fish (Genova® is my favorite; not sponsored). Hellmans/Best Foods® mayo is my favorite in this recipe (again, not sponsored). Make sure to get bread and butter pickles; they add the perfect tanginess to this salad.
  • Wait until the avocado is really ripe. The perfectly ripe avocado makes a huge difference in this salad. Here’s how to tell an avocado is ripe. If it’s not fully ripe, it won’t add the flavor and creaminess that a ripe avocado will.

FAQs

Can I lose weight eating tuna salad?

A lot people who are looking to lose weight eat tuna because of its high level of protein. For just 3 ounces of tuna, you’re getting a whopping 20g of protein and only 100 calories. Tuna is a great protein to eat while trying to maintain a lower carb/lower calorie diet. As long as you are aware of how much mayo you are adding (mayo will add the most calories), you will have a great, healthful meal. 

Is tuna salad healthy?

This salad is much healthier than most tuna salads you’ll find, thanks to the avocado, all the veggies, and the avocado-based dressing. The avocado (which has healthier fats) is mashed which replaces a lot of the mayo that is typically in tuna salads.

Ingredients

  • 3 cans (5 ounces EACH) tuna, well drained (I recommend Genova packed in olive oil which ends up being 4 ounces once drained)
  • 3 tablespoons finely diced celery
  • 3 tablespoons finely diced bread and butter pickles
  • 2 tablespoons finely diced red onion
  • 2 tablespoons finely diced flat leaf parsley

Dressing

  • 1 small avocado, separated
  • 1 tablespoon lemon juice
  • 1/3 cup light mayonnaise (use up to 1/2 cup for more creamy consistency)
  • 1 teaspoon Dijon mustard
  • 1 teaspoon olive oil
  • Salt and pepper

Instructions

  • PREP: Thoroughly drain the tuna and transfer to a large bowl.
  • DRESSING: Slice an avocado in half, and remove the peel and pit. Mash one side of the avocado to get 3 tablespoons mashed avocado. Dice the other side to get about 1/4 cup of diced avocado and set aside. Add the 3 tablespoons mashed avocado to a small bowl. Add in the 1 tablespoon lemon juice, 1/3 cup mayo, 1 teaspoon Dijon mustard, 1 teaspoon olive oil, and salt and pepper to taste.
  • SALAD: Finely dice the celery, pickles, red onion, and parsley. Add the 3 tablespoons celery, 3 tablespoons pickles, 2 tablespoons red onion, and 2 tablespoons parsley to the bowl with the tuna and diced avocado. Add the dressing on top and gently stir to combine. Taste and adjust seasonings to taste. Add extra mayo here if you want a creamier salad (1-4 tablespoons extra).
  • SERVE: Serve in a croissant roll with lettuce, in a lettuce wrap, with pita chips, etc. -- however you'd like to enjoy it! Best enjoyed same day and shortly after making it; the avocado begins to brown after about an hour or two.
