I don’t go to school and I’m lucky enough to work from home, so if I want a nice hot and fresh lunch, I can do that! However, I do get quite busy during lunch and having some meal prep or the option to whip up a quick meal in only 10 minutes is certainly welcome! I think the universal “quick lunch” go-to recipe is a Tuna Sandwich.
Would you believe that I’ve wanted to make a Tuna Sandwich for years? Honestly, although canned tuna is so cheap, protein-packed, and versatile, canned tuna has been a pesky protein for me for years simply because I’ve been really adverse to using it! Let’s be honest here - it’s not very pleasing on the eyes when you open the can up… and it sure has a VERY distinct smell! Draining it is most definitely not something I jump out of bed to do.
However, like the process of many recipes, for instance, peeling and de-veining shrimp for some incredible Shrimp Scampi or to make Shrimp Tempura, the gross moments in the preparation certainly are worth the end results! If you also consider canned tuna a pesky protein because you feel “ick” about what’s on the inside of the can, then I certainly encourage you try out this Open Tuna Sandwich as part of your Live to Cook one-month challenge! Not only will you get more comfortable with using canned tuna, but you’ll have a delicious and super easysandwich as a result of conquering that obstacle!

Tools Needed to Make Canned Tuna Sandwich
Ingredients for the Best Tuna Sandwich
All ingredients with their quantities can be found by scrolling to the bottom of this post or by pressing the “Jump to Recipe” button for the FULL PRINTABLE recipe card, plus you can save the recipe for later. You can also scale the recipe based on how many sandwiches you’re looking to make so that you have the right amount of tuna salad filling - no ratio calculations required for you!
- Tuna: I used canned flaked light tuna. If you’re using solid tuna, you’ll need to flake it after draining it.
- Dijon mustard: Any type of Dijon mustard will work here, but I’m using a jalapeño dijon mustard since that’s the only one I had on hand! As I mention in my free motivational guide to explore your potential in the kitchen, Make Cooking Fun!, if there’s a suitable substitute that you’ve already got on hand, no need to get something else! The jalapeño flavor of this mustard definitely contributed to the flavor of my tuna salad, but no worries if you’ve got regular dijon mustard! If you want some extra kick, you could always add in whole jalapeños.
- Dill pickles: You can use whatever type of dill pickles you like, but I’m sticking with plain baby dill pickles here!
- Japanese mayo: If you don’t have Japanese mayo, you can certainly use some regular mayonnaise. The Kewpie variety is amazing to add creaminess to this sandwich that regular mayonnaise just won’t give.
- Celery: If you really want to cut down on the prep time of this sandwich - or if you’re someone who doesn’t even like celery! - you can even substitute the whole celery with celery salt! You’ll get the same flavor with just a bit without that crunch and potential “overbearing” taste of raw celery.
- Chives
- Green onions
- Sourdough bread
How to Make This Open-faced Tuna Salad Sandwich Recipe
Drain any excess water from the cans of tuna and transfer the tuna to a large bowl. Add the chopped green onions, chives and celery (use celery salt instead if short on time).
Add mayonnaise, mustard and mix well to combine.
Add chopped dill pickles and some of the pickling juice.
Mix and then taste to adjust the ingredients as per your preferences.
Toast the bread if you prefer and then spread the tuna salad from earlier to the slices of bread.
Add as much or as little as you like.
Tuna sandwich is ready to enjoy!
Variations
- No mayo: If you don’t want to use mayo of any kind, you can make the recipe lighter by using sour cream, cottage cheese, or even Greek yogurt.
- Heat: Add a touch of sriracha sauce to your tuna salad mixture to bump up the heat!
- Fish: Feel free to swap out the canned tuna for canned salmon to experience the same sandwich but with a completely different flavor profile from the salmon!
- Chicken: Fancy some poultry? I’ve never actually used canned chicken before, but I’m sure this mixture will be amazing with chicken in place of tuna!
- Herbs: You can experiment with dill, basil, or parsley for slightly different flavor profiles.
- Add-ins: Lettuce, tomato slices, onion slices, avocado.
- Bread: The bread you use can have an impact on the overall experience of your sandwich! Feel free to experiment with white sandwich bread, Belgian bread, or even Ciabatta and discover your favourite with this tuna salad mix!
What If I want to add Cheese to My Tuna Sandwich?▼
Of course you can add some cheese to your sandwich! This will turn your sandwich into a Tuna Melt, and it would be prepared in a similar way to grilled cheese. In this case, you want to work with bread slices that are not toasted. Butter two slices of bread, then put the tuna filling on the bottom bread. Next, simply add shredded or sliced cheese (I recommend a combination of cheddar cheese and mozzarella, or some other pully cheese to get flavour and cheesiness!) over the tuna salad mixture. You can either broil the breads if you’re leaving this sandwich open-faced, or you can add a top slice of bread and cook the sandwich over the pan until the cheese is molten.
What to Serve with Tasty Tuna Sandwich▼
These Open-Faced Tuna Sandwich are well-balanced and have everything you need for a satisfying lunch! However, if you want to pair the sandwiches with a side for a complete meal, then here are some ideas:
TIPS to Make the Most Delicious Tuna Sandwiches
- While regular mayonnaise will work well to make these sandwiches, to get a creamier and richer texture, use the Japanese (kewpie) mayonnaise instead.
- Tuna sandwiches are great on toasted or un-toasted bread, however, not all breads are created equal. I’d pair a regular sandwich bread with the tuna for an un-toasted sandwich while for a toasted sandwich, use something crusty like a sourdough.
- Make sure you have drained most of the moisture from the canned tuna to ensure the sandwich does not become soggy.
- The best type of canned tuna for this recipe would be a meaty albacore variety.
- This tuna sandwich can be used to make the most amazing tuna melts by grilling the sandwich with cheese, bacon, avocado and cucumbers for example. Go crazy and make these sandwiches your own.
How to Store Tuna Sandwiches
The Tuna Salad Filling
Store any extra Tuna Salad filling in an airtight container in the fridge. Due to the tuna, fresh herbs, and mayo in this mixture, I would not keep it in the fridge for longer than 3 to 4 days. The longer you keep the tuna salad filling in the fridge, the more likely it is to become soggy.
The Tuna Sandwiches
You can store assembled tuna sandwiches in the fridge for up to 3 to 4 days. To best preserve them, I recommend you tightly wrap them in plastic wrap. Then, place those wrapped sandwiches in an airtight container. You can reheat them gently over a non-stick pan, or enjoy them cold!
