How to Make Spicy Tuna Rice Balls
Let’s get cooking!
Rinse the sushi rice under cold water until the water runs clear. This helps remove the excess starch so your rice turns out perfectly fluffy. It’s a bit of a ritual, but well worth it! Once rinsed, cook the rice according to the package instructions, using the 2 ½ cups of water. This usually takes about 20 minutes. Let it cool slightly once done, trust me, you don’t want to burn your hands!
In a bowl, mix the drained tuna, Kewpie mayo, sriracha, and a couple pinches of salt until well combined. The texture will be creamy and super satisfying. And wow just wow, this mixture smells incredible.
Now, here’s the messy (but fun!) part: wet your hands with water to prevent sticking. With your wet hands, grab a handful of sushi rice and shape it into a triangle or ball. It’s like sculpting but much tastier!
Next, make a small indentation in the center of your rice shape and fill it with a spoonful of the spicy tuna mixture. Don’t be shy here, go ahead and pack it in there!
Encapsulate the filling with the rice, reshaping it as necessary. You want a nicely rounded rice ball that’s full of those flavors. If it’s a bit uneven, no worries, it’ll still taste amazing!
Take a piece of nori and wrap it around your rice ball. Sprinkle with sesame seeds if desired. Don’t you just love that contrast in colors?
Serve immediately or wrap in plastic for a portable snack. These can even be tossed in a lunchbox for a fun midday treat!

These spicy tuna rice balls can be served warm or at room temperature. I love to pair them with a side of pickled ginger or some light soy sauce for dipping. A crisp cucumber salad or miso soup would be a great accompaniment too!
Storage
Leftovers can be stored in an airtight container in the refrigerator for up to 2-3 days. However, I’d advise against freezing them, once thawed, the texture won’t be quite the same.
Reheating Instructions
To reheat, just pop them in the microwave for about 30 seconds until warmed through. You may want to wrap them in a damp paper towel to keep them from drying out.
Freezer Friendly?
For this recipe, I wouldn’t recommend freezing the rice balls. They may lose their signature texture once thawed.
