Expert Tips
Here are some helpful tips to ensure the best results for your dish:
- Use Fresh Ingredients: The quality of your fish affects everything; always choose fresh or sushi-grade ingredients.

Preparation Steps
To create this Delicious Spicy Tuna Onigiri Recipe, follow these straightforward steps. Begin by cooking sushi rice according to package instructions. Once the rice is ready, allow it to cool slightly. Meanwhile, mix together canned tuna with mayonnaise, sriracha, and chopped green onions in a bowl. Combine thoroughly until the mixture is creamy and spicy.
Once everything is prepared, grab a small bowl of water to prevent the rice from sticking to your hands. Wet your hands and take a handful of rice. Form it into a triangle shape, ensuring that it’s compact but not too tight. Next, create a small indentation in the center of the rice triangle and fill it with the spicy tuna mixture. Carefully mold the rice around the filling to encase it fully.
Repeat this process until you have shaped all your onigiri. You can optionally wrap each onigiri with a strip of nori for added flavor and presentation. Serve immediately or store them in an airtight container in the refrigerator for later enjoyment.

Storage Tips
To keep your Delicious Spicy Tuna Onigiri Recipe fresh, store them properly in an airtight container. If you’ve added nori, it’s best to consume them within a few hours to avoid sogginess. For longer storage, keep the onigiri without nori wrapped separately.
You can refrigerate the onigiri for up to three days. If you want to enjoy them later, consider freezing them. Wrap each one individually in plastic wrap before placing them in a freezer bag. Thaw in the fridge overnight before consuming.
