What is tuna tartare made of?

  • tuna: Purchase sushi-grade tuna from a trusted fishmonger. Ask where it’s coming from and make sure the fish isn’t fishy.
  • cucumber: Peel the cucumber, remove the seeds and cut into small cubes.
  • Avocado: If you’re making the tuna tartare a few hours ahead of time, wait until just before serving to dice the avocado.
  • sauce: Add soy sauce, sesame oil and sriracha (if using) and mix.
  • Green onions: Sprinkle the chopped green onions over the tartar.

Compatibility with tuna tartar

I had grilled wonton chips in a ladle of tuna tartare. You can also use baked chips such as purple potato chips or plantain chips if you prefer. For a low-carb option, serve with bell peppers, jicama, or celery sticks.

How long does tuna tartare last?

Tuna tartare is best eaten the same day it is made, but it will keep in the refrigerator for up to two days.


  • fish: Substitute salmon for sushi for tuna.
  • cucumber: Use English or Persian cucumbers instead of regular cucumbers.
  • Sriracha: If you don’t want spicy tuna tartare, skip the sriracha.
