This avocado tuna salad recipe is delicious, light, and refreshing. It’s super easy to make and comes together in only ten minutes. Crunchy cucumber, red onion, and bell pepper pair perfectly with creamy avocado and flaky tuna. Top everything with a flavor-packed, tangy lemon and olive oil dressing!
I love making this family favorite in the spring and summertime. It’s the perfect cookout side dish and is easy to transport to an outdoor event. It’s also a great everyday dinner side or an easy take-along lunch.
Canned tuna is so easy to work with! It’s truly the perfect ingredient when you need something fast and simple. Plus, it really provides a nice boost of protein.

Ingredients
- Veggies — Cucumber, red onion, and red bell pepper (or your favorite color)! I enjoy using red bell pepper because it’s the sweetest.
- Avocados — If you won’t be making this salad for a couple of days, look for avocados that are fairly hard at the grocery store. They’ll soften and become ripe quickly at room temperature. Making it right away? Try and find some that give a little when pressed gently with your finger.
- Tuna — I prefer using flaked light tuna packed in water, though any type will work. You could also substitute canned salmon in this recipe, if desired.
- Chives — This tasty herb adds lots of flavor and color.
- Homemade dressing — Fresh-squeezed lemon or lime juice, extra virgin olive oil, salt, and ground black pepper. You can also use Dijon mustard.
Instructions
Assemble salad:
- Chop up your cucumber, red onion, bell pepper, and chives. Transfer everything to a large mixing bowl.
- Open canned tuna, drain well, and add it to the bowl, along with veggies.
- Remove pits from avocados. Peel, dice, and place the cubes in the salad bowl.
- Mix all ingredients together until well incorporated!
Make dressing:
- Grab a small mason jar or bowl and add dressing ingredients: freshly squeezed lemon juice, olive oil, salt, and pepper. Whisk vigorously until emulsified.
- Do a taste test and add more salt or pepper, if necessary!
Serve:
- Pour dressing over the salad ingredients and toss to coat. Garnish with fresh parsley or cilantro.
- Serve and enjoy!
Recipe Tips
- This low carb salad is even more delicious when you take the time to chop your veggies up nice and small because you’ll get a little of each ingredient in every bite and they’ll mix better with the tuna.
- Any type of tuna will work for this recipe, though I typically use flaked light tuna packed in water. Feel free to use whatever you’ve got on hand; you can even substitute canned salmon!
- If you buy avocados for this recipe and they’re ripening too quickly, you can place them in the refrigerator (whole)! They’ll keep longer in the cold than they will on the countertop.
- I like using red bell peppers in my salad because they’re the sweetest. But you can use whatever color you prefer (or even mix and match)! Also, feel free to incorporate other vegetables, if desired such tomatoes, celery, lettuce (romaine lettuce) and so on.
- The dressing for this recipe is very light and delicious. So, it does not include mayonnaise or Greek yogurt. For this reason, it doesn’t have the texture of a creamy classic tuna salad, but if you prefer, feel free to add them (mayo and yogurt) to the dressing.
- You can enjoy this tuna avocado salad by itself, or you can serve it with tortilla chips or even use it as a sandwich filling.
- Some people love to add cheese, such as feta, to this salad. So, if you enjoy a bit of cheese, feel free to add it.
It’s easy to make this salad ahead of time for work or even for a summer cookout or side dish. Simply combine all ingredients and assemble the salad per recipe instructions, but don’t add the avocado.
Instead, leave the avocado whole and keep it to the side. Dice it up and mix it in when you’re ready to serve! It will be the last ingredient you add before eating to help keep it green and fresh for as long as possible.
- To Store: Place any leftover avocado tuna salad in an airtight container and store it in the refrigerator for up to 3 days. The avocado may begin to brown and oxidize, but the lemon juice will help slow this process. I do not recommend freezing this salad. You can also leave the salad in the mixing bowl, cover it with plastic wrap, and place it in the fridge.

- Make sure the bell pepper, onion, and cucumbers are finely diced, so they blend nicely into the tuna.

- If the avocados you purchased for this salad are softening too fast, put them in the refrigerator (whole) to slow ripening.

Hi. How does the avacado stay fresh if you dont eat the entire salad in one sitting? Thanks!
It will be good for a day.
Have not made this yet but am thinking not enough dressing to even taste on 3 cups of veggies and 2 avacodo plus 2 cans of tuna ……sounds like a good dress just not. Enough.
It actually is, but you can double the ingredients for the dressing. This way you will have more dressing.
I made this and love it and it’s plenty of dressing.
Yum! Had this for lunch today, it was delicious and I felt so healthy eating it! 🙂
Awesome, Heather! Happy to hear that 😉
Awesome salad and very filling too! I used seasoned salt and homemade pepper sauce in place of the salt and black pepper and it tested amazing.
Thanks a lot!
This looks so delicious!
It was 😉 Hope you give it a try 😉
Your recipe calls for two 15-ounce cans tuna. But tuna generally comes in either 5 or 12 ounce cans – so do I need a total of 30 ounces or is it a typo and I need two 5-ounce cans, a total of 10 ounces?
12 ounce can works.
Absolutely delicious and refreshing! I can’t have tuna because mercury goes right to my brain and stays there. It has already done some damage. But I used canned pink salmon, and it was perfect. What a great salad! Thanks.
Yes this recipe works really well with canned salmon too. Happy you like it 😉
