Tuna Salad Sandwich on a croissant

Tuna Salad Sandwich | On Croissants

Tuna Salad: Love it or hate it? I asked this question on social media the other day and was so surprised how many of you LOVE it! I definitely hated tuna salad growing up, but have turned over a new leaf and now love the stuff. Love it on bread, love it by itself, love with crackers. Just love it. And, it never gets old either! Lucky for me, my four (soon to be five!) family members love it just as much as I do!

This recipe really activates the ol’ taste buds with crunch from celery, green onions, and lettuce, combined with tuna and a sweet, vinegar splash from banana peppers! So delicious! If you like Tuna Salad you should also try my Amazing Chicken Salad Recipe (with Grapes). Both are great on a croissant!

If you happen to hate tuna salad, I apologize. {But you might want to consider trying my version just once to rule it out for sure! Just saying…}

If you love it, then enjoy it! It’s tasty stuff!

Main Ingredients Needed

I add in a lot of crunchy, vinegary ingredients because I love the bite vinegar gives, but you are welcome to adjust this tuna salad sandwich as you’d like! This is just a starting point; make it, taste, and adjust the ingredients as you like.

  • Tuna – It can’t be a tuna salad without tuna! 2 cans will do for this recipe. I usually buy mine packed in water instead of oil. Drain well!
  • Croissants – If you have never had a sandwich using a croissant, you’re missing out. Don’t worry, proceed to make this tasty recipe for your induction to croissant sandwiches. Buy store-bought or make homemade croissants.
  • Dill Pickles, Celery + Green Onions – These bring not only flavor to the base of the salad but also texture! The contrast in texture makes this recipe rise above the rest.
  • Real Mayonnaise – This is controversial but I PROMISE you if you use real mayonnaise this recipe will turn out right and good. Please, no miracle whip.
  • Salt + Pepper – these are always invited to the party, super important for flavor.


These are the toppings that I like on my sandwich, but feel free to add whatever you like!

  • tomato
  • cucumber slices
  • lettuce
  • pickles
  • mild banana pepper rings


And here’s a whole bunch of ways to customize this recipe! Tuna salad is good with just about any sandwich topping so here we go:

  • avocado
  • hard boiled eggs
  • chickpeas
  • bell peppers
  • cucumber
  • black olives
  • nuts (pecans, almonds, cashews, etc.)
  • apples

How to Make a Tuna Salad Sandwich | Directions

This Tuna Salad Sandwich recipe comes together really quickly and is a great salad to have during the summer with fresh veggies from the garden! Here are the step-by-step directions. More details and measurements are found in the printable recipe card down below.

Step 1: Make Tuna Salad

Add tuna to a large bowl. Next chop up some onions, celery, and pickles. I like a big crunch to tuna ratio, so I go a little overboard but feel free to add less if desired.

Next up? The MAYO. A few important pointers: miracle whip is NOT mayonnaise and is forbidden in this recipe. Low-fat versions are also not permitted. Use the real, full fat, mighty tasty mayo. Sprinkle in good ol’ salt & pepper.

Now stir that baby up. And take a minute to enjoy. And cry. And savor the moment that is beautiful tuna salad. We’re almost done!

Step 2: Slice Croissants

Now take one of these beauties and give them a slice. I love croissants! {*if you want to ever elevate a sandwich/get people to like it- make it on a croissant. AMAZING.}

Step 3: Assemble Tuna Sandwich

Now, spoon on that yummy tuna. And lettuce, tomatoes, and cucumbers if you like.

Mild pepper rings. My darn older sister got me hooked on these. I visited her a few months ago in Idaho and we had some hefty burgers with these little buggers on top. Holy delicious batman. So, now I add them to everything. They add a nice pop and vinegary zing. They are optional, but you really should put them on your sandwich because I said so.

    I do not particularly like tuna salad, but this was delicious! I think the chopped dill pickles and the flaky croissants made the difference. This recipe is a keeper. Love it!

    Girl Friend, yo just solved a major problem. Having these ladies over for lunch tomorrow. these lovely tuna sandwiches will do just the trick. Plus I love tuna sandwiches………………and they better.

    I make my tuna salad the exact same way as this recipe. I love making a sandwich on a croissant as well.

    As another tuna treat, I make a ‘tuna melt.’ I toast an English muffin, put some extra mago on both side of the muffin, pile on the tuna salad, top with a tomato slice and then a slice of cheese (I love Swiss)…then I put it in the toaster over (on a tray or piece of tin foil) for a few minutes until thee cheese melts. Of boy…it is so yummy.

    Lauren, I make my tuna salad just like you; however, I add a squeeze of fresh lemon to the mix. I don’t know why, but it adds something very special.

    I am a bariatric patient, I am wondering if the carbs that are counted in this recipe are from the bread being included in this, because tuna a lean protein, which is good for me, but all the carbs with this recipe is not

    Delicious.. I used a cup of Best Food Mayo.. Also…..croissant should be cut almost all the way through and lightly toasted…both inside and out.. Now that is a croissant , tuna sandwich.
    Thanks..loved the dill pickles..always used relish before.

    I make my own mayo but I don’t make it frequently because it needs to be used within 1 week and who in the heck can (or needs) to eat an entire cup of mayo in 1 week or less on a regular basis? I just made mayo yesterday for a green sauce that was part of a recipe for Peruvian chicken. So I figured I’d use of the rest making tuna fish, which we hadn’t had in several months. I was looking to see what was out there to do differently for tuna fish than what I normally do. I haven’t really found anything different unless it’s to put fruit like grapes or raisins in (yuck). I make tuna fish pretty similar to this recipe although I also add in dill, fresh lemon juice (if I have lemons on hand), usually some mustard, and I also add in carrots (either chopped up in the food processors or using the food processor to grated them). Sometimes I will add in sliced olives as well (different varieties add different flavors and I just add in whatever I have on hand, but they are all good).
    Glad to see I’m not the only one who doesn’t like the sweet stuff in my tuna fish salads!

    I just made this now and it was insanely delicious. I added hot giardiniera like the Italian place by me does and it was fantastic. Also, I agree, sweet pickles suck.

    Try using “Duke’s” mayo. Also, “The Best” is a relative term. I’MO, this tuna salad is much too sour – tangy. Some of the ingredients need to be toned down, as they tend to overwhelm. A good balance (of ingredients) is the key to a successful recipe. Believe me, I learned the hard way! Thanks for listening 🙂

    I gave this 5 ☆’s because I actually make mine this exact same way 😁 I thought it was my best recipe for tuna but now yours comes along lol. I do have a little secret tweak but don’t tell anyone. I cut up jarred cornichons and add instead of dill pickles sometimes and it is amazing! 🙆‍♀️

    Great using dill pickles. I do run out of dill pickles so often even stocking my pantry with a spare jar so I use dill weed too. Your recipes are great. The tuna and egg salads are yummo.
