Best tuna sandwich
Elise Bauer

My parents started making tuna salad sandwiches this way years ago. And, as far as I'm concerned, theirs is the best and only way to make a tuna fish sandwich.

In addition to tuna, it has red onions, celery, capers, lemon juice, parsley, mayo, and the kicker? Cottage cheese. You might think that cottage cheese is a weird thing to add to tuna salad, but believe me, it really works!

The Best Canned Tuna for Tuna Salad

To make the best tuna salad sandwich, it helps to start with high-quality canned tuna. We prefer tuna that is packed in extra virgin olive oil, because the oil intensifies the flavor of the tuna.

Both Trader Joe's and Whole Foods have excellent canned tuna packed in olive oil that work perfectly for this tuna salad. The brands we most often use are Wild Planet Albacore Solid Wild Tuna in Extra Virgin Olive Oil and Genova Yellowfin Tuna in Olive Oil.

If you don't like the oil that the tuna is packed in, you can always drain it, and add back a tablespoon or so of your own high quality extra virgin olive oil.

If all you have is tuna packed in water, drain it, and add a tablespoon of extra virgin olive oil to it. Finding the best canned tuna for your taste may require a bit of experimentation with brands.

Doubling This Recipe

This recipe makes enough tuna salad for 1 large sandwich or 2 smaller sandwiches. You can easily double the recipe. Any leftover tuna salad will keep in the refrigerator for 3 to 4 days.

Why Cottage Cheese Works in Tuna Salad

Cottage cheese might seem like a strange addition to tuna salad, but trust us when we say it's a perfect in this sandwich. It adds more protein, plus a creaminess and richness. You can use non-fat or light cottage cheese, if you're worried about the extra calories.

Add More Vegetables

If you’d like extra veggies in your tuna salad, go for it! Try a 1/4 cup or so of chopped cucumber, red bell pepper, carrots, celery, or even fresh greens, such as spinach or arugula. You may have to add more mayo or cottage cheese to get the consistency you want, but it works!

Swaps and Substitutions

  • Hate Dijon mustard? Use yellow, stone-ground, brown, spicy, or your favorite mustard.
  • Don’t have fresh parsley or dill? Use tarragon, or any other fresh herb you enjoy.
  • Swap in scallion or yellow or white onion for the red onion.
  • Dislike onions? Leave them out!
  • Don't have capers? Just add some chopped pickles, chopped green olives, or pickle relish to get that extra brine and vinegar flavor.
