Let’s Make Low FODMAP Tuna Salad!

Classic tuna salad might seem boring, but I make it every week, as it is an economical, easy recipe to make for lunches and snacks – and the way we make it is delicious!

This is the approach I take to make a Low FODMAP Tuna Salad.

Growing up, tuna salad meant drained canned tuna, mayonnaise, lemon juice, diced celery, black pepper and maybe some dried dill or tarragon. I was never a pickle-relish in tuna person.

Read our article, All About Canned Tuna, for the lowdown on how to best shop for tuna! Some water-packed tuna contains”broth” and high FODMAP ingredients. We tell you everything you need to know.

Know Your FODMAPs

The only issue, from a low FODMAP perspective, is the celery.

As you can see in the image below, the suggested low FODMAP amount of 10 g of celery is a small amount.

It might be just fine for your portion of canned tuna, but I like a bit more crunch.

So, very early on in my low FODMAP diet days I got to thinking about what else would lend a fresh, green, crunchy aspect to my tuna salad, in lieu of celery and I came up with two options that I turn to again and again.

cucumber, bok choy and celery

Celery, Bok Choy Or Cucumbers

Bok choy is low FODMAP in very generous 1 cup (75 g) amounts, while cucumbers have no detectable FODMAPs in amounts of ½ cup (75 g).

I tried both in my low FODMAP tuna salad and loved both versions!

The bok choy (above right) lends a pepperiness that I love in tuna anyway and the cucumber (center of image) is something I always have around, so these new approaches to low FODMAP tuna salad were a win-win, in my book.

Bread or Salad

I am partial to eating my tuna salad as a “salad” and use carrot sticks to scoop it up or sometimes gluten-free pretzels or corn chips.

If you are a sandwich kind of person, did you know that you can have 1 slice of white bread made with wheat flour and still be low FODMAP compliant!

Check out the Monash University Low FODMAP Diet Smartphone app and peruse the Bread section; you might be surprised.

This is a very straightforward recipe. Once you read it through and make it, you will be able to make it by heart. And in our busy lives, that is a great help!

Total Time: 5 minutes
Author: Dédé Wilson


  • 2, 5-ounce (142 g) cans tuna, preferably water packed
  • 3/4 cup (60 g), diced bok choy stems, OR
  • 3/4 cup (113 g), diced European hothouse cucumber, OR
  • 1/2 medium (10 g) celery stalk, diced

  1. Scrape the tuna into a wire-mesh strainer set over a bowl and squeeze out as much liquid as possible, using the back of a wooden spoon; don’t hold back! Discard the liquid. Place the tuna in a mixing bowl, stir in the chopped vegetable of choice (only one of them!), mayonnaise, lemon juice, dill (to taste) and then generously season to taste with pepper.
