1 (4.5-ounce) can Portofino Solid Albacore Tuna in Extra Virgin Olive Oil – This flavorful tuna serves as the creamy backbone of the filling.

1½ tablespoons mayonnaise – Adds a luscious creaminess that complements the tuna and spiciness of the sriracha.

1 teaspoon sriracha hot sauce – Spice it up! The sriracha gives an exciting kick to the filling.

½ teaspoon rice vinegar – Balances the richness and brings a touch of tanginess to the mix.

1 scallion (green parts only) – Chopped finely, these bright green bits add freshness and a mild onion flavor.

toasted black sesame seeds (optional) – Use these for a crunchy texture and an appealing look once everything is assembled.

3 sheets toasted nori – This seaweed wrap holds your onigiri together and adds a lovely umami flavor.

How to Make Easy Japanese Tuna Onigiri

Follow these simple steps to prepare this delicious Easy Japanese Tuna Onigiri:

Step 1: Rinse the Rice
Begin by rinsing the Japanese short-grain rice in a fine-meshed sieve under cold water. Keep rinsing until the water runs clear. This step removes excess starch and ensures your rice becomes delightfully sticky.

Step 2: Cook the Rice
Combine the rinsed rice with 15 fluid ounces of cold water. Cook in a rice cooker according to the manufacturer’s directions. If you’re a saucepan kind of cook, bring it to a boil, reduce the heat, cover, and let it simmer for 16 to 18 minutes until the water is absorbed. Once cooked, remove it from heat, fluff it gently, cover with a kitchen towel, and let it rest for about 10 minutes.

Step 3: Prepare the Tuna Filling
While the rice cools, grab a medium bowl and mix together the tuna, mayonnaise, sriracha, and rice vinegar. Stir until everything is well combined—don’t be shy; you want that wicked sriracha flavor evenly spread throughout. Toss in the chopped scallions for a fresh touch.

Step 4: Shape the Onigiri
Prepare a bowl of room-temperature water and sprinkle a small amount of kosher salt onto your hands. Moisten your hands in the water, sprinkle with salt, then grab roughly ½ cup of the sushi rice. Shape it into an oblong ball in one palm.

Step 5: Fill and Mold
Create a small dent in the center of your rice ball and add about a tablespoon of the tuna filling inside. Carefully close the rice around the filling. Adjust the rice as needed to ensure the tuna gets enveloped properly.

Step 6: Form into Triangles
Using both your hands, gently mold the rice ball into a wide triangular shape. Be careful not to compress too hard—you’re going for a fluffy texture here.

Step 7: Finish and Serve
Sprinkle the outside with black sesame seeds if you’re using them, then wrap each onigiri in a sheet of nori. Top with a little extra tuna filling for a pop of color and flavor. Serve them immediately and enjoy the delightful mix of flavors and textures!

With these steps, you’ll be able to create a tempting batch of Easy Japanese Tuna Onigiri that not only tantalizes the taste buds but also makes for a fun and interactive meal. Enjoy the process, savor the flavors, and relish in the smiles of those around you as you share this delightful dish.
