Best Tuna Salad

Just because a tuna salad sandwich is quick and easy to prepare doesn’t mean it must be boring and bland. Take this copycat Subway Tuna Salad recipe, for example.

You can whip it up in only a few minutes, but it’s a deliciously satisfying meal for lunch or dinner at home or perfect for anyone who is brown-bagging it.

Subway restaurants may be known for their sandwich artists, but there isn’t any reason why you can’t make an even better tuna salad hoagie!

Why is this the Best Subway Tuna Salad Recipe?

There are countless recipes for tuna salad online. Many of them are fancy, calling for expensive tuna or herbs and other seasonings. Who needs it?

Subway’s tuna salad recipe is barebones and allows the real taste of the fish to be front and center. The mild tuna salad flavor becomes the perfect base for adding all of your favorite toppings.

Whether you want to keep your sandwich classic with just a bit of shredded lettuce and sliced tomatoes or spice things up with pickled jalapenos, onions, and a few slices of cheese, the choice is yours!

Subway Tuna Salad Ingredients

There are a few components to this tuna sub sandwich. There’s the basic sandwich with tuna salad, cheese, and bun. Then you have the various vegetable toppings and sub dressings if desired. Here’s a list of what you need:

Tuna Salad Sandwich

  • Water-packed tuna – I recommend yellowfin tuna
  • Mayonnaise
  • White American cheese slices
  • Sub sandwich buns

Vegetable Toppings

  • Shredded lettuce
  • Tomatoes 
  • Cucumbers
  • Bell peppers 
  • Onions
  • Black Olives 
  • Dill pickle slices 
  • Sliced jalapenos

Sub Sandwich Dressing

  • Oil – Canola or light olive oil is best.
  • Red wine vinegar

Ingredient Substitutions

One reason why Subway’s sandwiches are so popular is that they offer such a wide range of toppings. But, when you make a Subway Tuna Salad sandwich at home, you have even more options.

Here are just a few topping suggestions that Subway doesn’t offer, along with alternative must-have ingredients.

Consider adding some of these toppings to your sandwich:

  • Sundried tomatoes
  • Avocados
  • Sprouts
  • Tarragon
  • Apple slices
  • Chopped hardboiled eggs

Tuna Types

There are a lot of different choices when it comes to tuna. Although the recipe calls for canned tuna in water, there is absolutely no reason why you can’t use oil-packed tuna instead.

When choosing your tuna, remember that anything labeled as skipjack or light tuna comes from smaller tuna species that typically have lower mercury levels.

Mayonnaise Alternatives

Mayo provides the creaminess that is so essential for a good tuna sub. However, depending on diet philosophy it is considered either healthy (low-carb/keto) or not the healthiest ingredient (low-fat/low-calorie).

  • Save calories and fat by using a light mayo instead.
  • If you are looking to eliminate mayo, many people like to substitute sour cream or Greek yogurt.
  • Another fantastic alternative is using mashed avocado with a touch of white vinegar or lemon juice to add some acidity.

Tuna Sandwich Bread Choices

You can change the entire tuna sandwich with your choice of bread. For the sake of your teeth, you should probably stay away from any crusty bread, but ciabatta or even focaccia bread are excellent choices.

If you are a bit daring, try something sweet, like raisin-nut bread, for a totally unique taste experience.

What Goes Well with a Tuna Salad Sub?

Try crunchifying your sandwich by topping the tuna salad with a handful of your favorite thick-cut potato chips.

Are you more of a fries person? That’s great, too!

Of course, you’ll need something to wash everything down, and the best way to do that is with something bubbly. Soda, seltzer, or even beer go great with this copycat Subway tuna salad recipe.

How to Store Tuna Salad

You can easily halve this tuna fish salad recipe by using only one can and a tablespoon of mayonnaise. But if you have any leftovers, keep them fresh in the fridge in an airtight container.

Remember, oxygen is the enemy, so use the smallest container you can, and press plastic wrap directly on top of the tuna to prevent it from drying out.

The tuna fish recipe from Subway keeps in the fridge for up to three days.
