Step‑by‑Step Instructions for Spicy Tuna Onigiri Recipe
Step 1: Prepare Sushi Rice
Begin by thoroughly rinsing 1 cup of sushi rice under cold water until the water runs clear. Cook the rinsed rice according to package directions or in a rice cooker. Once cooked, transfer the rice to a bowl and gently mix in a combination of rice vinegar, sugar, and salt while it’s still warm. This seasoning adds flavor to your Spicy Tuna Onigiri, ensuring each bite is delicious.
Step 2: Make Tuna Filling
While the rice cools, drain one can of tuna and flake it into a mixing bowl. Add in 2 tablespoons of mayonnaise, a dash of sriracha (adjust to your spice preference), 1 teaspoon of sesame oil, and 1 tablespoon of soy sauce. Finely chop 1 green onion and mix it in for added crunch. Stir everything until well combined, creating a flavorful and creamy filling for your onigiri.
Step 3: Assemble Onigiri
Once the rice is slightly cooled, wet your hands with salted water to prevent the rice from sticking. Take a handful of the seasoned rice and form it into a small ball. Using your thumb, create a well in the center, fill it with about 1 tablespoon of the tuna mixture, and then encase it with more rice. Gently shape the rice into a triangle, being careful not to press too hard, so your onigiri remains fluffy.
Step 4: Wrap in Nori
Cut strips of nori into approximately 1-inch wide pieces. Take a formed onigiri and place it on a piece of nori, then wrap it around the rice ball, securing it lightly. This not only adds an extra layer of flavor but also makes your Spicy Tuna Onigiri easier to handle. Repeat the process with the remaining rice and filling, creating a delightful assortment for serving.
Step 5: Serve or Store
Once your onigiri are assembled, serve them immediately for the best texture, or arrange them on a platter for a lovely display. If you need to store them, wrap each onigiri individually in plastic wrap and refrigerate for up to two days. Try to let them reach room temperature before serving to maintain that wonderful chewy texture that makes Spicy Tuna Onigiri so delightful.
How to Store and Freeze Spicy Tuna Onigiri
Fridge: Wrap each onigiri individually in plastic wrap to keep them fresh. They can be stored in the refrigerator for up to 2 days; let them reach room temperature for the best texture before serving.
Freezer: If you need to freeze your onigiri, wrap each one securely and store them in an airtight container for up to one month. Thaw overnight in the fridge before enjoying.
Reheating: When ready to eat, feel free to microwave onigiri for about 10-15 seconds. This will help to retain their delightful chewiness, making your spicy tuna onigiri satisfying once again!
Storage Tip: Always check the texture after refrigeration or freezing; if they seem a bit dry, a light sprinkle of water before reheating can help restore moisture.
Make Ahead Options
These Spicy Tuna Onigiri are perfect for busy meal prep enthusiasts! You can prepare the sushi rice and the tuna filling up to 24 hours in advance, allowing the flavors to meld beautifully. Simply rinse and cook 1 cup of sushi rice, season it, and store it in an airtight container in the refrigerator. For the filling, mix the drained canned tuna with mayonnaise, sriracha, sesame oil, soy sauce, and green onion, then refrigerate as well. When you’re ready to serve, just shape the rice around the filling and wrap in nori for a delightful, delicious snack that’s just as satisfying and fresh as if you made it on the spot!

Spicy Tuna Onigiri Recipe FAQs
What type of rice should I use for onigiri?
Absolutely! Sushi rice is the best choice for onigiri as its short-grain variety becomes sticky when cooked, allowing the rice balls to hold their shape. Make sure to rinse it well to remove excess starch, which will help achieve the perfect chewy texture.
How should I store leftover onigiri?
After wrapping each onigiri individually in plastic wrap, you can store them in the refrigerator for up to 2 days. For the best taste and texture, let them reach room temperature before serving, as this will enhance the fluffiness of the rice.
Can I freeze spicy tuna onigiri for later use?
Yes, you can! To freeze, wrap each onigiri securely with plastic wrap and store them in an airtight container. They will stay fresh in the freezer for up to one month. When you’re ready to enjoy, thaw them overnight in the refrigerator or gently reheat in the microwave for 10-15 seconds to restore their delicious chewiness.
What if my tuna filling is too dry or too wet?
If your tuna filling is too dry, consider adding a little more mayonnaise or yogurt for creaminess. Conversely, if it’s too wet, you can drain the tuna more thoroughly or adjust the amounts of the wet ingredients, like mayo or sriracha. Mix everything well to get a creamy consistency, which is essential for your spicy tuna onigiri.
Are there any dietary considerations I should keep in mind?
Very! For those on gluten-free diets, use tamari instead of soy sauce. Additionally, for nut allergies, be cautious with sesame oil, as it’s optional. Don’t forget that you can create vegan versions with chickpeas or marinated mushrooms if you’re looking for a plant-based alternative. Customize to suit your specific needs!
Can I make onigiri ahead of time?
Of course! Preparing your onigiri ahead of time is a great idea. Just remember to wrap them individually and store them in the fridge or freezer. If making them in advance, it’s advisable to prepare the filling a few hours ahead, allowing the flavors to meld beautifully. Enjoy the convenience without sacrificing taste!
