This Tuna Stuffed Avocado is a recipe I created years ago with the tuna packed in olive oil that I’ve been infatuated with for so long, and if it’s HOT today where you live I think this is perfect for a no-cook low-carb dinner. Of course, there’s evidence on the blog of how I love the combination of tuna, avocado, cilantro, and lime, but for people who don’t like cilantro I’d just leave that out for this tasty tuna stuffed avocado recipe.

And I’m sure no one will feel bad when you hear that when I updated the photos for this very old recipe, I also updated the recipe to make it a bit easier. The old recipe peeled the avocado and then scooped most of it out, leaving a “shell” of avocado to stuff with tuna. But when I made this again (a few times to get it just right) it seemed unnecessarily difficult to me to handle the peeled avocado. So the new recipe uses the avocado skin as a vessel to hold the tasty tuna, avocado, cilantro, lime, and red onion mixture.

I recommend serving this with lime wedges so you can add a generous squeeze of lime at the table. I thought one large avocado and one can of tuna was enough for a light lunch or dinner for two people, but I’ll give you some easy side dish recommendations below! And if you’re dying from the heat, I hope this no-cook recipe can help!

What ingredients do you need for this recipe?

  • tuna packed in olive oil, preferably Genova Tuna Packed in Olive Oil (affiliate link)
  •  ripe avocado
  •  red onion
  •  cilantro
  • Olive Oil (affiliate link)
  •  Mayo
  •  fresh-squeezed lime juice, I used my fresh-frozen lime juice 
  •  sea salt (or salt) and fresh ground black pepper to taste
  •  additional lime for serving, if desired

What canned tuna did I use to stuff the avocado?

I learned to love tuna packed in olive oil when I tried fancy imported Italian tuna, and if that’s in the budget for you it’s really amazing. But when I looked for a cheaper alternative, I fell in love with Genova Tuna Packed in Olive Oil (affiliate link), and that’s the one I use all the time now. I like this tuna so much I spotlighted it as a Kalyn’s Kitchen Pick in my collection of Low-Carb and Keto Canned Tuna Recipes.

If you want to use this as a main dish for a more substantial meal, it would taste great with Cucumbers Caesar, Cucumber Salad with Easy Balsamic Dressing, Thai Cucumber Salad, Tomato, Cucumber, and Radish Salad, or Cucumber Salad with Parsley and Feta for a dinner that doesn’t take much work.
