Ingredients

Tuna mayo onigiri with concentrated, rich umami achieved by pan-frying canned tuna with its oil to evaporate excess moisture. Combine with mayonnaise and salt to create a special filling, shape with plastic wrap or by hand, and wrap with nori seaweed. Served with a side of quick-pickled cucumber to create a complete, satisfying meal.

  • Prep
    • Pour the canned tuna with its oil into the pan. Retaining the oil is key to a rich umami flavor.
  • Heat Control
    • Sauté slowly over medium-low heat, breaking it up with chopsticks until the moisture completely evaporates.
  • Seasoning
    • After evaporating the moisture, add 1 tbsp of mayonnaise and 1/4 tsp of salt, then mix well.
  • Shaping
    • Both plastic wrap and bare-hand shaping methods are shown; choose whichever you prefer.
  • Nori Technique
    • Cut the nori diagonally in half with scissors to wrap the onigiri, or spread rice directly onto the nori. Wrapping the finished onigiri in plastic wrap softens the nori for a chewy texture.

    Evaporating moisture from the tuna

    Place 1 can of tuna with its oil into a frying pan and heat over medium-low. Carefully sauté while breaking it up with chopsticks. Cook until you hear a crackling sound, the moisture is completely evaporated, the color deepens, and a savory aroma rises.

    Wrapping with nori

    Cut the nori diagonally in half with scissors to make triangles. You can either place the shaped onigiri on the edge of the nori and wrap it around, or spread the rice directly onto the nori, place the tuna mayo in the center, and fold the nori over.

Why This Dish Tastes So Good

Combining the inosinate in tuna with the glutamate abundant in shio kombu and nori seaweed creates an umami synergy, dramatically boosting the flavor. Additionally, tossing the cucumber with shio kombu utilizes osmotic pressure for moisture control (dehydration), removing excess water to create a pleasant, crunchy texture while concentrating the flavors for a delicious finish.

Evaporating Moisture to Concentrate Umami

First, prepare one can of tuna and transfer it to a frying pan along with all of its oil. Sautéing it slowly over medium-low heat to evaporate the moisture is the ultimate secret to making this onigiri incredibly delicious. While most onigiri recipes call for draining the oil, pan-frying the tuna with its oil transfers the umami into the oil. Completely evaporating the water prevents the flavor from becoming diluted, concentrating only the rich, savory taste. Sauté carefully while breaking it up with chopsticks until you hear a crackling sound, indicating the moisture is gone.

Classic Fillings and the Rise of Tuna Mayo

In Japan, traditional and popular onigiri fillings include sour pickled plums (umeboshi), salty salmon, and savory kombu kelp. However, in modern Japan, "tuna mayo" has established itself as an equally—if not more—popular classic. As you continue to heat the tuna in the pan, the moisture gradually evaporates, the color deepens, and a savory aroma fills the air. Cooking it thoroughly like this ensures that when mixed with mayonnaise, it won't become watery, creating the perfect base for a filling that blends beautifully with the rice.

Finishing the Special Tuna Mayo Filling

Transfer the thoroughly dried-out tuna to a bowl. Add 1 tbsp of mayonnaise and 1/4 tsp of salt to tighten the flavor. Mix everything evenly and thoroughly with a spoon. Sautéing the tuna to remove moisture allows it to absorb the rich creaminess of the mayonnaise, resulting in a deep, creamy flavor that stands out from ordinary versions. This simple extra step elevates the quality of the entire onigiri, creating a special tuna mayo filling that offers a completely different level of satisfaction from the very first bite. You can see how beautifully the mayonnaise coats every fiber of the tuna.

Quick Cucumber Pickles: The Perfect Side

To complement the onigiri, we'll also make "asazuke" (quick pickles), a simple and traditional Japanese side dish. Thinly slice 1/2 cucumber into rounds and place them in a bowl. Add 2g of shio kombu (salted kelp)—a popular ingredient packed with saltiness and umami—and massage it well with your hands. Add 1/2 tsp of toasted sesame seeds for a nutty aroma, mix well, and let it sit at room temperature for about 10 minutes to let the flavors meld. The crunchy texture of the cucumber combined with the savory umami of the shio kombu makes it the perfect partner for onigiri.

Preparing the Rice and Shaping Onigiri

Prepare 300g of warm rice in a bowl, add a pinch of salt, and gently fold to combine. For shaping, we'll first demonstrate using plastic wrap. Spread about 100g of rice onto the wrap, place the special tuna mayo in the center, cover it with a little more rice, wrap it up, and shape it into a triangle. We will also demonstrate the traditional Japanese home method of shaping directly with wet, salted hands. While disposable gloves or plastic wrap are increasingly used today for hygiene, many still believe that onigiri shaped with bare hands by a grandmother tastes the best—both methods have their own merits.

Two Ways to Wrap Onigiri with Nori

For the essential nori seaweed, use scissors to cut it diagonally in half into triangles. The first wrapping method is to place the shaped onigiri on the edge of the nori and wrap it around. The second method is to spread the rice directly onto the cut nori, place the tuna mayo in the center, add more rice on top, and fold the nori over. This second style leaves a bit of the tuna mayo peeking out from the top, making it look incredibly appetizing. There are no strict rules for making onigiri, so feel free to enjoy shaping them in your own favorite style.

Plating and Tasting: A Moment of Bliss

Line a plate with a vibrant green bamboo leaf and arrange the finished onigiri beautifully. Add the quick-pickled cucumber to the empty space, and you'll have a gorgeous plate that looks like it came straight from a restaurant. Breaking the onigiri in half reveals the rich, concentrated tuna mayo filling inside. The crisp aroma of the nori, the fluffy rice, and the savory tuna mayo spread across your palate—a simple yet perfectly calculated deliciousness that will bring a smile to your face. Try this easy trick to make the ultimate onigiri!
