These 15-minute Japanese Tuna Onigiri are not only incredibly quick to whip up, but they’re also wonderfully satisfying and packed with flavor. Perfect for a light lunch, a speedy snack, or even a quick breakfast when you’re on the go, onigiri are a staple in Japanese cuisine for a reason. Their simplicity belies their deliciousness, and this tuna-filled version is a classic for a good reason. We’re going to make them so easy, you’ll wonder why you haven’t made them before! The key is having your rice ready, and then it’s just a matter of a few simple steps to transform humble rice and tuna into these delightful little rice balls.
Ingredients:
Making Your Tuna Filling
This is where all the flavor magic happens! The combination of tuna and mayonnaise is a classic for a reason. It creates a creamy, savory filling that complements the plain rice perfectly.
1. Prepare the Tuna: Open your can of tuna. If you’re using tuna packed in oil, I recommend draining off most of the oil, but leaving just a little behind can add a nice richness to the filling. If you’re using tuna packed in water, drain it thoroughly. Place the drained tuna into a small bowl.
2. Combine with Mayo: Add the Japanese mayonnaise to the bowl with the tuna. Japanese mayonnaise has a slightly richer, tangier flavor than Western mayonnaise, which I find works wonderfully here. However, regular mayonnaise is perfectly acceptable if that’s what you have on hand. Stir the tuna and mayonnaise together until they are well combined and form a spreadable mixture. You want it to be creamy but not too wet. If it seems a bit dry, you can add another small drizzle of mayo. Taste this mixture – it should be seasoned and delicious on its own!
Assembling Your Onigiri
Now for the fun part – shaping these tasty treats! The key to handling the rice is to keep your hands slightly damp so the rice doesn’t stick.
3. Prepare Your Rice: Make sure your cooked short-grain rice is still warm or at room temperature. It’s much easier to shape warm rice than cold, hard rice. In a small bowl, mix the 1/2 teaspoon of salt with about 2 tablespoons of water. This salted water will be used to moisten your hands, which is crucial for preventing the rice from sticking. Have your nori sheets ready to go, and if you’re using sesame seeds for garnish, have those in a tiny dish as well.
4. Shape the Onigiri: Dip your hands into the salted water and rub them together to moisten them. Take about 1/2 cup of rice and place it in the palm of one hand. Gently flatten the rice into a small disc. Make a small indentation in the center of the rice. Now, spoon about 1 to 2 tablespoons of your prepared tuna and mayonnaise mixture into this indentation. Don’t overfill it, or it will be difficult to seal. Carefully bring the edges of the rice up and around the filling, enclosing it completely. Gently cup your hands around the rice and begin extract to shape it. You can aim for a classic triangular shape, a round ball, or even a slightly flattened oval. The key is to press gently but firmly enough to form a compact ball that holds its shape. Repeat this process with the remaining rice and tuna filling.
5. Wrap and Garnish: Once you have shaped your onigiri, it’s time to add the nori and any optional garnishes. If you’re using full sheets of nori, you can cut them into strips or shapes that will wrap around the base or side of your onigiri. I find a strip about 2 inches wide and 4-5 inches long works well to wrap around the bottom half of a triangular onigiri. Gently press the nori onto the rice. If you’re using sesame seeds, sprinkle them onto the exposed parts of the rice for an extra touch of flavor and visual appeal. You can also press them gently into the surface of the rice. If you prefer less nori, you can simply use a small piece to hold the onigiri together or to add a decorative touch.
Notes on Freshly Cooked Rice:
If you are cooking your rice from scratch for this recipe, aim for about 1 cup of uncooked short-grain rice. Cook it according to your rice cooker’s instructions or on the stovetop. The key is to let it steam for about 10-15 minutes after cooking to achieve the perfect sticky texture. You’ll want to use it while it’s still warm for the best results when shaping your onigiri. If your rice has cooled down too much, you can gently reheat it in the microwave for a minute or two.
There you have it – delicious, homemade Japanese Tuna Onigiri in under 15 minutes! These are best enjoyed fresh, but they also keep well for a few hours if you need to make them ahead. Pack them in a bento box or a simple container for a satisfying and portable meal. Enjoy this taste of Japan, made with love and in record time!

And there you have it – your super simple, incredibly delicious Japanese Tuna Onigiri, ready in just 15 minutes! This recipe truly shines because it’s so accessible, requiring minimal ingredients and prep time, making it perfect for busy weeknights, quick lunches, or even a satisfying snack.

These onigiri are fantastic on their own, but they also make a wonderful addition to a bento box, served alongside a light miso soup, or even as a light appetizer.

Frequently Asked Questions:
Can I make the rice ahead of time?
Absolutely! You can cook your sushi rice a day in advance and store it in the refrigerator. When you’re ready to make your onigiri, simply warm the rice gently in the microwave or on the stovetop until it’s pliable enough to shape. This can save you even more time when you’re in a rush.
What other fillings can I use?
The possibilities are nearly endless! Besides tuna, popular fillings include seasoned salmon, teriyaki chicken, seasoned kombu (kelp), or even umeboshi (pickled plum). You can also mix in chopped scallions, sesame seeds, or a tiny bit of wasabi for a little kick.
