Tuna Avocado Brown Rice Bowls

Ideal lunch (or dinner!) situation, right here. ♡

This Mediterranean-inspired tuna salad comes together super-easily in the time it takes to cook a batch of brown rice, and always somehow tastes like so much more than the sum of its parts. It’s made with a simple mix of canned tuna, creamy avocado, crunchy cucumber, crisp red onions, a sprinkling of feta and herbs (I’m partial to fresh dill here, but you’ve got options). Then everything is tossed in a zippy lemon-sumac-cumin dressing and served over brown rice. And whether you then serve the salad up warm — or pack it away in the fridge for lunch the next day — every bite promises to be so flavorful and satisfying.

I love this recipe because it’s one of those salads that’s hearty without feeling too heavy. It’s naturally gluten-free and can also be dairy-free, if you nix the cheese. It’s easy to meal prep in advance. And it’s endlessly customizable in whatever ways you may need. Feel free, for example, to swap in another fish or protein if tuna isn’t your thing (although I have to say it is delicious here). And while we love serving this salad over chewy brown rice here in our home, you could easily swap in another type of rice, quinoa, farro, orzo, or any other base that may sound good. See below for even more fun add-ins that you’re welcome to toss in too.

Tuna Salad Ingredients

Tuna Salad Ingredients

Before we get to the full recipe below, here are a few brief notes about the ingredients you will need to make this tuna salad recipe:

  • Tuna: I recommend a good-quality brand of oil-packed canned tuna for this salad. (Water-packed canned tuna will also do, but it will be less flavorful.) If possible, please consider purchasing a more sustainable brand of tuna too.
  • Feta cheese: Tangy crumbled feta is mixed into the tuna salad, but I also recommend adding a bit extra as a garnish just before serving.
  • Avocado: Ripe avocado adds such lovely creaminess and texture to this salad.
  • Cucumber: Diced cucumber (I recommend either English or Persian cucumbers) adds freshness and crunch.
  • Red onion: Very thinly sliced (or diced) red onions add a hint of sharp, sweet flavor. Feel free to briefly rinse the sliced onions in cold water if you would like to mellow out their flavor.
  • Chopped dill: I love adding a handful of chopped fresh dill to this salad. But if dill isn’t your thing, fresh parsley, cilantro or chives would be delicious alternatives too.
  • Brown rice: I love cooking up a batch of brown rice to serve as the base for this salad, either on the stovetop (I recommend this method from Cookie + Kate) or in the Instant Pot. See note below about other rices or grains that you’re welcome to use instead of brown rice if you prefer.
  • Lemon-Sumac Dressing: Finally, we will toss this salad in a zippy dressing made with olive oil, lemon juice, Dijon, ground cumin, ground sumac, fine sea salt and freshly-ground black pepper. If you don’t have ground sumac in your pantry, this recipe will still be delicious without it. But I highly recommend picking some up because it adds such delightful lemony, floral flavor.

Recipe Variations

There are so many delicious ways that you’re welcome to customize this tuna salad recipe! For example, feel free to…

  • Use a different protein: Salmon, trout, mackerel, shrimp, or chicken would all be great alternatives to tuna in this salad.
  • Use a different rice/grain/pasta: Any other variety of rice (various kinds of white rice or wild rice) would work well too, or you’re welcome to use quinoa, farro, orzo, or another base that you prefer.
  • Add greens: We also enjoy adding in some fresh arugula, spinach, or kale if we happen to have some on hand.
  • Add nuts/seeds: A sprinkling of toasted pine nuts, almonds, walnuts, pepitas, sunflower seeds or other favorite nuts/seeds would be lovely.
  • Add sun-dried tomatoes: If you happen to have a jar of sun-dried tomatoes sitting in your pantry, they would be a delicious addition to this salad.
  • Add olives or capers: Olives or capers could add some delicious briny flavor.

  1. How long will this keep? Looking for meal prep ideas!!

    • Same question here,I have tried to make something similar for the meal prep, however the second day I found that the cucumber will somehow drained and lots of excess water from cucumbers.

    • If you take the seeds out of the cucumber, they won’t weep as much. I cut the cucumbers in half and then use a teaspoon or half teaspoon to remove the wet/seedy center of cucumbers.

  2. How about using quinoa rather than brown rice?

  3. Made this tonight for supper and it was really good! I followed the recipe exactly except doubled the dressing. I agree with Ali it would so good with spinach, chick peas, etc. This is an anything go recipe, I think . I put this together in minutes and had to wait for the rice to be cooked and voila dinner! I did substitute goat cheese for feta with no problem. Thank you for an easy, GOOD dinner recipe! My husband loved it!

  4. This was fantastic! After a couple of bites I had to force myself to portion out my other lunches because I could have eaten the whole bowl. Flavors are amazing and it’s a nice light feeling meal that gets me through the rest of the workday.

  5. Omg this is so good. Made twice now and I love it. I served it on wild rice
