Subway Tuna Salad Sandwich Copycat Recipe

Starting from Pete’s Subway, Subway has come a long way to become popular for its very own Tuna Salad sandwich. If you’re a big fan of this sandwich but don’t want to spend a fortune buying it every day, we have you covered.

The best thing about tuna salad is that you can whip them up anytime. It’s only a matter of minutes and you can have it anytime you want, be it for lunch, dinner, or maybe breakfast if you’re someone who really loves fish. So, let’s get to the recipe!

What’s in the mix!

Subway’s tuna salad recipe is simple, allowing the fish’s natural flavor to shine through. The light tuna salad flavor serves as the ideal foundation for a variety of toppings.

And when it comes to customization, the choice is yours whether you want to keep it simple with simply shredded lettuce and sliced tomatoes or go all out with pickled jalapenos, onions, and a couple of cheese slices.

Unlike the classic tuna salad, cheese, and bread sandwich, this tuna sub sandwich has a few different components. There are various veggie toppings and, if wanted, alternative dressings. Here’s a rundown of what you’ll require:

  • Tuna with a lot of water — I recommend yellowfin tuna.
  • Mayonnaise
  • Slices of white American cheese
  • Buns for sub sandwiches
  • Lettuce, shredded
  • Tomatoes
  • Cucumbers
  • Peppers (bell)
  • Onions
  • Olives noires
  • Slices of dill pickle
  • Jalapenos, sliced

And, how can we even forget about the countless dressings that Subway offers? The ideal oil to use is canola or mild olive oil. You can also throw in some vinegar or red wine.

But what if you want it differently?

The variety of toppings is one of the reasons Subway’s sandwiches are so popular. You can have even more alternatives when making a Subway tuna salad sandwich at home. Here are a few topping ideas and substitute ingredients that Subway doesn’t carry. Consider including some of the following toppings on your sub:

  • Tomatoes, dried in the sun, preferably
  • Avocados
  • Apple slices, Sprouts, Tarragon
  • Eggs that have been chopped

Tuna Type?

Canned Tuna

When it comes to tuna, there are several options. Although the recipe asks for canned tuna in water, there’s no reason why you can’t use oil-packed tuna. When selecting your tuna, keep in mind that anything branded as skipjack or light tuna comes from smaller tuna species with reduced mercury levels. For this recipe, I have used this brand.

Mayo: To Be Substituted or Not To Be

Mayonnaise gives that smoothness that is crucial for an excellent tuna sub. However, depending on which side you are on when it comes to dieting, mayo is either a good (low-carb/keto diet) or an unhealthy (low-fat/low-calorie diet) item. Instead, if you want to be on the safe side, use light mayo to save calories and fat.

Or else, you can use sour cream or Greek yogurt as a substitute for mayo. Another great option is to add some acidity to mashed avocado with a dash of white vinegar or lemon juice.

Bread: The Best of It

You may customize the tuna sandwich by experimenting with different types of bread. Any crusty bread should be avoided for the health of your teeth, but ciabatta or even focaccia bread are good alternatives. However, if you’re feeling adventurous, try something sweet, like raisin-nut bread, for a whole other flavor sensation.

Putting It All Together: Making The Salad

To make tuna salad, the following are the steps:

  1. Drain any extra water from the tuna. In a small dish, flake the drained tuna using a fork.

2. Stir in the mayonnaise until completely combined.
3. In a bowl, homemade Subway tuna salad.
4. Half the sub sandwich bread.

5. To make the sandwich, start by piling tiny scoops of tuna salad on top of the bread.

6. Put chosen toppings on the bottom of the bun.
7. Then, cut the cheese squares into triangles and arrange two of them on top of the veggies.
8. If preferred, top the sandwich with a dollop of mayonnaise, oil, and vinegar.

Finally, seal the bun and enjoy!

Salad but it’s Make As You Want

When it comes to tuna salad, there is always more to it than the sandwich. You may try it as a tuna melt, wrap, or salad.

  1. Tuna Melt: Spread tuna on the bottom half of the sandwich, then top with cheese. Place the bottom bun with tuna and cheese and the top bun on a baking pan. Remove from the oven and broil until the cheese has melted. If desired, garnish with additional ingredients.
  2. Tuna Salad Wrap: To make a tuna salad wrap, spread the tuna salad and toppings on a big flour tortilla and fold it up like a burrito.
  3. Salad with Tuna: Toss the shredded lettuce in a basin. Top with veggies, cheese, and tuna salad scoops. Dress with a vinaigrette or oil and vinegar dressing.

Side-dishes To Choose

Subway’s tuna fish recipe calls for a salty side dish to assist in balancing the tastes. The crunchier the potato chips, the better. Try your sandwich by sprinkling a handful of your favorite thick-cut potato chips on top of the tuna salad. Are you a fan of french fries? That’s fantastic as well!

Naturally, you’ll need something to wash it all down, and the best way to do it is with something bubbly. This homemade tuna salad sandwich pairs well with soda, seltzer, or even beer.

Thinking About The Future: How To Store

This tuna fish salad dish may simply be halved by using only one can and a spoonful of mayonnaise. If you have any leftovers, store them in an airtight container in the fridge.

Remember that air is your enemy, so use the tiniest container possible and place plastic wrap immediately on top of the tuna to keep it from drying out.

But, how long will the magic last? Subway’s tuna fish dish may be stored in the refrigerator for up to three days.
