Ingredients for Tuna Salad Sandwich
- White flake tuna – The packets of tuna and cans of tuna will both work great. White flake tuna will be easier to mix.
- Celery – Celery provides a lovely crunchy texture to the tuna salad mixture.
- Pickle relish – Sweet or dill, you choose! Both will work in this recipe, so it’s just a matter of which you prefer more.
- Mayonnaise – Mayonnaise makes these sandwiches perfectly creamy with a slight tang.
- Red onion – The strong flavor of red onion pairs really well with tuna. You can use yellow or white onion if you prefer.
- Dijon mustard – Trust me, dijon mustard makes all the difference in this recipe! Don’t just use regular mustard, the dijon is delicious.
- Garlic powder – A touch of garlic powder helps to season this tuna salad to perfection.
- Lemon juice – Lemon and fish are a common pairing, so why not use lemon juice in tuna salad. The tart flavor goes so well with all of the other ingredients.
- Salt and pepper – A little salt and pepper helps to round out the flavors and combine all of the ingredients together well.
How to Make a Tuna Salad Sandwich
- Drain the packets or cans of white flake tuna until all the water is gone. Then, place it in a large mixing bowl.
- Add the diced celery, pickle relish, dijon mustard, mayonnaise, lemon juice, diced red onion, garlic powder, salt and pepper to the bowl of tuna fish.
- Mix all of the ingredients until thoroughly combined.
- Next, place a generous amount of tuna salad onto a slice of bread and serve open faced or between two slices. Add sliced tomatoes and lettuce for extra crunch and flavor!
- Serve and enjoy.
What to serve with a tuna sandwich
Classic salted potato chips are a great side to have with tuna salad sandwiches. But you can also get creative and make something different. Whip up some fruit dip and serve your favorite fruit alongside this delicious sandwich. Or, make a fruit salad with all your fresh summer fruit.
Instant pot potato salad or deviled eggs would also be great served with a tuna sandwich. If you want a warm side with your cold tuna salad, make some air fryer potato wedges or air fryer french fries.
How to Store Leftover Tuna Salad
Leftovers are best when stored separately from the bread, tomatoes, and lettuce. Place tuna salad into an airtight container and store in the refrigerator for 3 to 5 days.
I do not recommend freezing this tuna sandwich recipe since mayonnaise based salads don’t tend to thaw well after being frozen.
What kind of bread is best for tuna sandwiches?
You can really use any type of bread, but my personal favorite is whole wheat. Something about the flavor of whole wheat bread and tuna salad is nostalgic! If whole wheat is not your thing, try thick sliced white bread, sourdough, rye or even a croissant.
Can I add cheese to my tuna salad sandwich?
Cheese is always a good idea! Swiss and provolone would go great with this recipe. However, you can also use cheddar, Colby jack, pepper jack, or any other cheese that you want.
- Lightly toast your bread before adding tuna salad so that it stays crisp till the very last bite.
- Feel free to add things like chopped nuts, raisins, and small diced fruit to give this tuna salad even more texture and flavor.
- Don’t make a sandwich until you’re ready to serve it! That way, the bread doesn’t get soggy and stays light and fluffy.
A tuna salad sandwich is a classic meal that everyone should know how to make…and now you do!
