This Tuna Salad Sandwich is absolutely packed with flavour and couldn’t be easier to make!
Tuna Salad Dressing
All good tuna salads start with a good dressing. Sure, tuna mayonnaise is great, but I also like to chuck in a few extras. For the dressing here’s what you’ll need:
- Mayonnaise – Full fat whole egg mayo for the fullest flavour. I don’t recommend reduced fat varieties, they’ll end up causing the salad to go bitter/sour.
- Mustard – A touch of dijon mustard gives a gentle background heat.
- Lemon Juice – Lemon juice and fish in general is a glorious combo. Here the lemon juice adds a hit of acidity and livens up the flavours in the salad.
- Salt & Black Pepper – Both to taste. A good few grinds of cracked black pepper goes beautifully here.
I like to make the dressing separately, then incorporate with the rest of the salad. This way all the ingredients blend properly, without you having to stir the tuna too much. The more your stir the tuna the mushier it gets.
Process shots: add ingredients to a small pot (photo 1), stir until evenly combined (photo 2).
Tuna Salad
What’s the best tuna to use?
I recommend canned tuna chunks. I find that sometimes using tuna flakes means everything ends up a little mushy. Chunks hold up a little better. In all cases do try and get your hands on a good quality brand (Princes in the UK is always great). The difference between quality and cheap brands is pretty huge! Oil, spring water or brine all work fine, just drain and add to a bowl.
In terms of extra goodies to add, here’s what I recommend:
- Celery – Adds a nice crunchy texture to the salad.
- Spring Onion – Tuna and onion is a glorious combo. Can sub finely diced red onion if you prefer.
- Dill Pickles – Add a really nice tangy flavour.
- Parsley – Adds a fresh burst of flavour. Dill also works nicely, but is much more powerful so you’ll need to use a lot less.
Can I make this ahead of time?
Sure can! Just tightly cover in the fridge until needed. It does tend to go a touch watery as it rests, so I recommend stirring through a dollop of mayo before serving, just to bring everything back together.

Tuna Salad Sandwich
When it comes to the sandwich, I tend to keep it fairly simple to let the tuna do the talking. 3 things I do add though are lettuce, tomato and cucumber. Tuna goes amazingly with tomato and cucumber, but I find they add way too moisture to the salad – hence why I add them as slices to the sandwich. Both are optional though. Lettuce non-negotiable, even it’s just to pretend to be healthy 😂
What else could I add to a tuna salad sandwich?Â
One thing I do sometimes add is avocado. Some recipes suggest sliced hard-boiled egg. Not really my preference but if it’s yours then go wild!
Should I toast the bread?
Totally down to preference. I usually don’t, just because I like my tuna either hot or cold (or room temp), not slightly warm from the toast. But toast does secure the filling more efficiently.
Process shots: slice bread (photo 1), spread with butter (photo 2), add lettuce (photo 3), add cucumber (photo 4), add tomato (photo 5), add tuna (photo 6).
What to serve with a Tuna Salad Sandwich?
- Crisp/Chip Recommendation: I prefer Ready Salted with this sandwich as the filling is already quite tangy.
- Side Recommendation: Gotta be a batch of Sweet Potato Wedges!
