Preparing Spicy Tuna Yaki Onigiri
If you’re looking for a delicious and unique treat, spicy tuna yaki onigiri is a fantastic option! These crispy rice balls filled with spicy tuna not only deliver an explosion of flavor but are also a delight to prepare. Whether you're making them for a casual lunch or as appetizers for a gathering, let's dive into how to whip up these delightful bites.
Step 1: Prepare the Spicy Tuna Mixture
Start by draining a can of tuna (about 5 oz is perfect). In a bowl, combine the drained tuna with Kewpie mayo and a tablespoon of Sriracha. For an additional kick, feel free to adjust the amount of Sriracha according to your taste. The result should be a creamy and spicy mixture that speaks for itself! This mixture is not just tasty; the fusion of flavors will have your taste buds dancing.
Did you know Kewpie mayo is richer and creamier than regular mayo? That's what makes it so special in various Japanese dishes.
Step 2: Prepare the Sushi Rice
Now, let’s move on to the star of our onigiri: the sushi rice. You'll need about 2 cups of cooked sushi rice or Japanese short-grain rice. To achieve the perfect texture, gently mix the rice with a bit of rice vinegar (optional, but recommended) and furikake, a savory Japanese condiment that adds layers of flavor. If you’re unsure where to find furikake, check out local Asian markets or even online retailers.
Step 3: Shape the Onigiri
Once your rice is seasoned and sticky, it’s time to mold it into those iconic triangular shapes. If you have an onigiri mold, fill half of it with the rice mixture. Add a spoonful of that luscious spicy tuna in the center and then cover it with more rice. Press firmly to form the perfect shape. Don’t have a mold? No worries! You can shape them by hand into triangles or even round balls—whatever you prefer!
Step 4: Grill for That Crispy Texture
To bring your spicy tuna yaki onigiri to life, heat a nonstick skillet over medium heat and add 1-2 tablespoons of cooking oil. Gently place your rice balls in the skillet and grill each side until it becomes beautifully crispy. The sound of sizzling will be music to your ears!
Step 5: Final Touches with Nori
After grilling, the last step for these delightful bites is to brush them with a little light soy sauce for an extra depth of flavor. Then, wrap each onigiri with a strip of nori seaweed. Not only does this add an elegant touch, but it also helps to keep the rice ball intact while enhancing the overall taste.
These spicy tuna yaki onigiri are best enjoyed fresh and warm. Serve them up for a delightful snack or party appetizer that brings a taste of Japan straight to your kitchen!

Variations on Spicy Tuna Yaki Onigiri
Vegetarian Options
If you’re looking for a vegetarian twist, try using avocado and cucumber for a unique filling. Simply mash ripe avocado and mix it with a touch of soy sauce and sesame oil for a creamy, flavorful interior. Another option is to create a spicy sesame tofu filling by finely crumbling firm tofu and mixing it with Sriracha and your favorite seasonings. These vegetarian variations maintain the delightful crunch and warmth of traditional spicy tuna yaki onigiri, making them perfect for any occasion.
Spicy Salmon Yaki Onigiri
For a delightful twist, swap out tuna for salmon to create a spicy salmon yaki onigiri. Combine canned or cooked salmon with mayonnaise and Sriracha, just like the traditional tuna filling. This variation offers a slightly richer flavor profile that's sure to impress seafood lovers. Don’t hesitate to experiment with different seasonings to personalize your filling! This version serves as a fantastic alternative for those who want to keep the yaki onigiri experience fresh and exciting.
Consider pairing these variations with a simple side salad or a light soup for a complete meal!
Cooking tips and notes for Spicy Tuna Yaki Onigiri
Tips for perfect rice
To achieve the best texture for your spicy tuna yaki onigiri, use sushi rice for its stickiness, which helps the rice balls hold shape. Rinse the rice thoroughly until the water runs clear to eliminate excess starch. This simple step makes a world of difference in achieving that perfect sticky consistency. Cooking your rice with a rice cooker allows for more even results. If you love a hint of tang, adding a splash of rice vinegar while mixing in the furikake elevates the flavor!
Grilling advice
For a crispy exterior, heat your nonstick skillet over medium, ensuring it's hot enough to create a golden crust without burning. Use cooking oil generously but not excessively to keep the spicy tuna yaki onigiri from sticking. Brush each side with soy sauce during the grilling for an added layer of umami that will have everyone asking for seconds. Flip them gently to maintain their shape, and remember: patience is key for that ideal crunch!
