Tuna Salad Crostini

Tuna Salad Crostini recipe

Tuna salad is one of my favorite lazy day lunches. It goes great in a sandwich, spread on toast, or eaten with crackers. Plus, it uses mainly pantry/refrigerator staples, like canned tuna, mayonnaise, onion, and spices. Scoop it on some sliced and toasted baguette and you’ve got a great hors d’ouevre or ‘tapas‘ for guests. I know a tuna salad crostini doesn’t sound like anything fancy, and it isn’t, but it is easy and tasty. If you do want something that sounds fancier you can try my Quail Salad, but that does take a lot more time.

Tuna Salad

A crostini is just a piece of toasted bread with a topping. You can pretty much get infinitely creative with this type of appetizer, and many people do. However a simple tuna salad is sometimes all I feel like having, especially if I don’t feel like really cooking (very rarely). All you need to do is empty a few cans of tuna into a bowl, add a bit of mayonnaise (I use my homemade mayonnaise since it’s really quite easy), add in some chopped red onion (can also use white or yellow), and mix it up with some spices.

You could even do this all in a stand mixer if you wanted, although I never have an issue just using two forks. If you feel you added a bit too much mayonnaise you could easily add in some breadcrumbs (or just more tuna). I personally don’t think I add too much mayo, but I know how sensitive some people can be. On the other hand I’m sure some people will say I don’t use near enough. I will say now I use far, far more than you would get in a Subway sandwiches tuna salad.

  • Mixing Bowl


  • 375 grams Canned Tuna drained

  • 1/2 Red Onion chopped
  • 1 tsp Black Pepper freshly cracked
  • 1 tsp Salt or to taste
  • 1/2 tsp Garlic Powder
  • 1/2 tsp Paprika
  • 1 Baguette Sliced into diagonals (look at the picture)


  • Add all the ingredients to a mixing bowl and mix up with two forks. You can also use a stand mixer on the paddle attachment, or even some egg beaters. Taste for seasonings and adjust.
  • Slice your baguette into pieces and toast. You can do it on a pan with some olive oil, or just in a toaster/toaster oven.
  • Add a scoop of tuna salad atop the toasted baguette slice, garnish with chopped pepper or herbs and serve.


Tuna salad holds well in the fridge provided it is in an airtight container. This works well for meal prep.
