What is Tuna Tartare?

Tuna Tartare Ingredients

Tuna tartare is a safe recipe to make and eat without risk, as long as you choose the right ingredients.

It is important that the tuna is of the highest quality, so it is best to choose sushi grade tuna with a deep red color and no fishy odors. The tuna will need to be kept cool and on ice until just before starting the recipe.

As well as for other raw fish recipes such as tartare, carpaccio and ceviche, it is important to use an acidic element. The acid triggers a reaction in the proteins, causing them to rearrange as if you had cooked the fish, making the tuna tartare even safer to eat. In this case, lime works perfectly.

Chopped avocado is the perfect base for this recipe.

The sesame ginger sauce adds flavor to tuna tartare.

How to make Tuna Tartare

To make a tuna tartare is easier than you may think. Start by making the tartare. Chop tuna into cubes, then mix the soy sauce, sesame oil, wasabi, ginger and salt into a bow to marinate the tuna. Let it rest for half an hour.

Make the base by cutting avocados into cubes. Place the tuna on the avocado using a mold, top with sesame seeds for crunch and serve.

Tuna Tartare Variations

The tartare is a versatile recipe. You only need a quality raw ingredient (fresh meat or fish), an acid such as lime juice, and your favorite condiments.

You can also add capers to the tartare instead of salt.

For a spicy tuna tartare, add sriracha to the marinade.

You can add small pieces of fruit such as mango, pomegranate, red fruits.

You can swap the avocado base for baked chips, cucumber slices or even rice.


The raw tuna must be fresh and of good quality for the dish to look as it deserves.

When you cut the tuna for the tartare, you can choice the size you like the most. There are those who prefer it as if it were minced meat, or those who enjoy finding well-differentiated cubes. We stay in an intermediate point, chopping it with the knife until making small cubes.

Remember to add little salt because the soy sauce already provides enough, and it will also depend on the type of tuna used, since fresh tuna will need more salt than other dried or salted tuna.

Always taste the tartar before serving it at the table to get the quantities right, especially with the salt and spiciness.

If you don't have a mold, cut the bottom of a tuna can with a can opener and then fill it to avoid cuts.


How to serve Tuna Tartare

You can serve the tuna tartare in the center of the table, and depending on the size of your mold, you can make even mini-tartares, very cute! Another great idea is to serve the tartare in teaspoons for a special event.

This recipe calls for toast, so you should serve a basket with toast in the center, which should be very crunchy. And now, enjoy this delicious, and juicy recipe.

How to store Tuna Tartare

If you have leftover tartare, you can keep it in closed containers in the refrigerator for 2-3 days. We advise you to keep each thing on one side, for example the tuna with its marinade in one container, and the avocado in another. This way the contrast while eating is greater.


Make the tartare. Chop the spring onion very finely and set aside.

Cut the tuna into small cubes.

In a bowl, mix the soy sauce, sesame oil, wasabi to taste, ginger and a pinch of salt.

Add the spring onion and tuna to the bowl, and stir well with the marinade, so that it is completely soaked. Let it rest for at least half an hour.

Cut the avocado into small cubes and put it in another bowl. Sprinkle it on top with the lime juice, a little salt and a tablespoon of olive oil. Stir well.

When the tuna has rested, you can directly plate your tartar.

Get a plating mold, either round or square. Place the mold on the plate in which you are going to serve the tartare, and fill the bottom with a layer of avocado. Ideally it should occupy half or less of the total height. Flatten slightly with a spoon.

Place the tuna on top and flatten it a little bit.

Remove the mold and sprinkle with sesame seeds. Serve and enjoy!
