Ingredients for Spicy Tuna Onigiri
Essential ingredients for the perfect onigiri
To whip up delicious spicy tuna onigiri, you'll need a handful of essential ingredients that create a well-balanced flavor profile. Start with 1½ cups of Japanese short-grain rice (sushi rice) and 15 fluid ounces of cold water for the perfect base. Your star ingredient—1 can of Portofino Solid Albacore Tuna in Extra Virgin Olive Oil—is key to achieving that flavorful filling. Mix this with 1½ tablespoons of mayonnaise, 1 teaspoon of sriracha hot sauce, and a splash of ½ teaspoon of rice vinegar. Don’t skip the scallions for a delightful crunch! A bit of kosher salt during assembly will enhance the overall taste, while toasted black sesame seeds make for a lovely garnish if desired.
Optional ingredients for customization
While the ingredients listed above form the foundation of your spicy tuna onigiri, feel free to get creative! You might consider adding avocado for creaminess, a sprinkle of furikake for extra umami, or even some finely chopped cucumber for a refreshing bite. These optional touches not only elevate the flavor but also add visual appeal, making your onigiri uniquely yours!
Preparing Spicy Tuna Onigiri
Bringing a little taste of Japan to your kitchen is easier than you think! Spicy tuna onigiri makes for a delightful snack or a light meal. So, grab your ingredients, and let’s dive into how to make these delicious rice balls from scratch!
Preparing the Sushi Rice
To start, the key to perfect onigiri is the sushi rice. Begin by rinsing 1½ cups of Japanese short-grain rice in a fine-meshed sieve under cold water. This step is essential — as you rub the grains, you’ll notice the water darkens. Keep rinsing until the water runs clear; this removes excess starch, improving texture. After draining well, combine the rice with 15 fluid ounces of cold water in a rice cooker. If you don’t have a rice cooker, use a medium saucepan and follow these steps: bring it to a boil, reduce the heat, and cover it to simmer for 16-18 minutes until the water is absorbed. Fluff the rice with a wooden spoon once done, then let it sit covered for about 10 minutes for the ultimate fluffy rice!
Making the Spicy Tuna Filling
While your sushi rice cools down, it’s time to whip up the spicy tuna filling. In a medium bowl, mix the drained 4.5-ounce can of Portofino Solid Albacore Tuna in Extra Virgin Olive Oil with 1½ tablespoons of mayonnaise, 1 teaspoon of sriracha hot sauce, and ½ teaspoon of rice vinegar. Give it a good stir with a fork until it’s well combined, adding 1 finely sliced scallion for that fresh, green crunch. This filling is where all the flavor comes from, so adjust the sriracha to your heat preference — are you a spice lover or do you prefer a milder dish?
Shaping the Onigiri
Now comes the fun part — shaping your spicy tuna onigiri! Start by filling a bowl with room temperature water and another small bowl with kosher salt for seasoning. Once the sushi rice is cool enough to handle, lightly moisten your hands in the water to prevent sticking. Sprinkle a pinch of salt onto your palms, grab about ½ cup of sushi rice, and form it into an oblong shape using one hand.
Add a tablespoon of your spicy tuna filling into the center before covering it back with rice. It’s crucial to shape it gently into a triangular form using both hands, rotating as you go. The goal is firm yet fluffy; you want those rice grains to hold together but not feel dense!
Wrapping with Nori
Here’s where you’ll add a little crunch! Take 3 sheets of toasted nori and cut them in half crosswise. Wrap each onigiri in a piece of nori, exposing a bit of the rice at the top. For an extra touch, place a small spoonful of tuna filling atop each onigiri. Isn’t that just the perfect finishing touch?
Serving and Enjoying
Your spicy tuna onigiri is ready to be savored! They are best enjoyed right after preparation while the rice is warm and the nori is crisp. Pair them with a light salad or some pickled vegetables for a complete meal. They make for an excellent lunch option for a busy day or a quick snack when you’re on the go. Not to mention, they’re adaptable — feel free to experiment with other fillings like avocado or veggies!
Now, roll up your sleeves and enjoy the process of making your delicious spicy tuna onigiri!

Cooking Tips and Notes for Spicy Tuna Onigiri
Tips for Perfect Rice Texture
To achieve the ideal texture for your spicy tuna onigiri, always rinse the sushi rice thoroughly before cooking. This step removes excess starch, resulting in a fluffier, stickier rice that holds its shape. The water should run clear when you're done. After cooking, let the rice rest covered with a kitchen towel, which helps enhance its humidity and is key for shaping.
Storing Onigiri for Meal Prep
When preparing onigiri in advance, wrap each rice ball in plastic wrap to keep them moist and fresh. Store in an airtight container in the fridge for up to 2 days. For longer storage, consider freezing; just make sure to wrap them tightly. Whenever you're ready for a quick snack or meal, simply reheat the onigiri in a microwave for a minute or two.

Ingredients
- 1.5 cups Japanese short-grain rice (sushi rice) about 2 rice cooker cups
- 15 fluid ounces cold water 440 mL
- kosher salt
- 1 (4.5-ounce) can Portofino Solid Albacore Tuna in Extra Virgin Olive Oil drained

- 1 teaspoon sriracha hot sauce
- 0.5 teaspoon rice vinegar
- 1 scallion (green parts only) finely sliced
- toasted black sesame seeds for sprinkling (optional)
- 3 sheets toasted nori cut crosswise in half
Instructions
- Prepare the rice: Place the rice in a fine-meshed sieve and rinse well under cold water, rubbing the grains of rice between your fingers, until the water runs clear. This helps remove any excess starch and improves the texture of the rice once cooked. Drain well.
- Combine the rice and water, and cook in a rice cooker according to the manufacturer’s directions. If you do not own a rice cooker: Combine the rice and water in a medium (non-stick, if possible) saucepan. Bring to a boil, reduce heat to low, and cook covered for 16 to 18 minutes or until the water has been completely absorbed. Remove from heat, gently fluff the rice with a rice paddle or wooden spoon, place a clean kitchen towel over the pot, top with the lid again, and let stand covered for 10 minutes.
- Make the filling: In a medium bowl, combine the albacore tuna, mayonnaise, hot sauce, and rice vinegar with a fork until evenly combined. Stir in the scallions.
- Assemble: Set aside a medium bowl of room temperature water and a small bowl of kosher salt for pinching. Once the sushi rice is cool enough to handle, start assembling the onigiri by hand.
- Lightly moisten your hands by dipping them in the water bowl. Sprinkle both of your palms lightly with kosher salt and rub them together. Grab roughly a ½ cup of sushi rice and gently press into a thick oblong shape in one palm of your hand. Add a tablespoon of the tuna filling, pinched together with your fingertips, to the center of the rice and close the rice over the filling. If necessary, use an additional pinch or two of rice to cover the filling.
- Gently shape the rice ball into a wide triangular shape using the palms of one hand and the fingers of your other hand, rotating the rice ball as you go. Avoid compressing the rice too hard, it should hold together well but be lightly packed. Sprinkle the outside of the onigiri with black sesame seeds.
- Wrap each onigiri in a nori sheet and place an additional small spoonful of tuna filling on the top of each onigiri. Serve immediately.
