Tuna tartare is one of those dishes I love to order at fancy restaurants.  Flavorful bites of heaven usually topped on a crispy rice cracker or mini toast!

My idea for this recipe was to make a low carb keto tuna tartare appetizer that wasn’t served on rice crackers.  But that proved to be quite challenging!

After many different attempts using everything from cheese to daikon, I came up with a perfect accompaniment that I think will please everyone – lotus root!

Lotus root I have found is a delicious alternative that is subtle in flavor so it doesn’t overpower the tartare yet is easy to prepare and fry.  It’s reminiscent of a potato with a slightly crunchy texture and a subtle sweet flavor.

So next time you have a craving for tuna tartare that is delicious and low carb, check out this Japanese style tuna tartare served on top of some pan fried lotus roots!

What is Japanese style tuna tartare?

I took a block of sushi grade yellowfin tuna, chopped it up then mixed it with different seasonings.  Then I took thinly sliced lotus root and fried them until slightly crispy.  All that’s left is assembling by placing the seasoned tuna on top of the fried lotus root.

Why use yellowfin tuna over other tuna’s to make tuna tartare?

Yellowfin is a leaner tuna, which is perfect for a tuna tartare rather than its fattier counterparts such as bigeye or bluefin tuna.  Fattier tuna would have a  more powerful flavor and overpower the dish, so they are better served in traditional sushi/sashimi dishes.

What is lotus root and are they low carb friendly?

Although it’s called a “root”, lotus roots are actually the stem of the lotus plant.  They have a low starch content making them a great low carb alternative for different dishes.  Keep in mind that lotus roots have around 0.5 net carbs per slice, so consume in moderate amounts as required by your personal diet.

What are Japanese shiso leaves?

Japanese shiso leaves are fragrant leaf with a unique flavor that you can find in many Japanese dishes.  You can find them in many Asian supermarkets.

Are there any tips on making yellowfin tuna tartare?

We recommend making this dish right before serving just for presentation purposes or otherwise, the tuna mixture will change in color due to the soy sauce.  So if you are intending to make this prior to serving, we suggest removing the soy sauce from the mix and just drizzling a couple of drops on top prior to serving.

To make Japanese style tuna tartare at home, the special ingredients you would need are Sesame Oil, Toasted Sesame Seed, sushi/sashimi grade yellowfin tuna, shiso leaves and lotus roots.  You can pick up most of these on Amazon or a local Asian supermarket.

Also, we’ve recently partnered up with Catalina Offshore Seafood to help bring you fresh yellowfin right to your door steps.  So if you don’t have access to a local fresh sashimi grade yellowfin, definitely give them a try!
