- ½ sheet nori (or 2 sheets for a stronger flavor)
- ½ teaspoon salt
- ½ teaspoon black sesame seeds (optional)
- Water for moistening the rice paddle

- 5.29 oz canned tuna in oil (or tuna in water)
- 2 tablespoons mayonnaise
- 1 tablespoon sriracha (or any preferred hot sauce)
This recipe allows you to enjoy a delightful blend of flavors and textures. The soft rice pairs well with the spicy tuna filling.

How to Prepare Spicy Tuna Onigiri:
Start by cooking 3 cups of short grain rice according to your preference. Allow it to cool before handling, as this will make assembly easier. Meanwhile, prepare the spicy tuna filling. Drain a 5.29 oz can of tuna and mix it with 2 tablespoons of mayonnaise and 1 tablespoon of sriracha for a fiery kick. Adjust the sriracha to taste, depending on your spice tolerance.
Next, in a large bowl, combine the cooled rice with ½ teaspoon of salt, ensuring the flavor is well integrated. To form the onigiri, wet your hands or rice paddle with a little water to prevent sticking. Take a small amount of rice and flatten it in your palm, placing a spoonful of the spicy tuna mixture in the center. Mold the rice around the filling, shaping it into a triangle or ball.
For extra flavor, sprinkle with black sesame seeds, if desired. Wrap one sheet of nori around each onigiri for a satisfying crunch. For additional tuna ideas, check out this delightful Tuna White Bean Dill Salad.

Serving Suggestions:
When serving Spicy Tuna Onigiri, consider pairing it with refreshing sides and dips to enhance the overall experience. First, a simple cucumber salad drizzled with rice vinegar can complement the spiciness of the onigiri beautifully. Alternatively, you can serve it alongside a light soy sauce or spicy mayo for dipping, adding an extra layer of flavor. If you’re in the mood for something unique, try presenting your onigiri next to a serving of spicy mango sorbet. The sweetness of the fruit, paired with a hint of chili, creates an exciting contrast that balances the heat of the tuna. Additionally, consider wrapping your onigiri in sheets of nori for a classic touch. Enjoy your meal with a cup of green tea for a complete Japanese-inspired dining experience. Each element can elevate your Spicy Tuna Onigiri, making it a delightful culinary treat.
Storage Tips for Spicy Tuna Onigiri:
To keep your Spicy Tuna Onigiri fresh and delicious, proper storage is essential. These delightful rice balls can be stored in an airtight container in the refrigerator for up to 2 days. However, for optimal taste and texture, consume them within 24 hours. If you plan to prepare them ahead of time, consider wrapping each onigiri in plastic wrap. This method prevents the rice from drying out, preserving the moistness you desire.
Reheating and Serving
When it comes to reheating, a quick blast in the microwave for about 10–15 seconds will help restore their warmth. Remember, overcooking may toughen the rice. Additionally, you might want to pair these spicy rice balls with a refreshing side. Try making tuna, white bean, and dill salad for a nutritious accompaniment, enhancing your dish’s overall appeal.
Freezing Spicy Tuna Onigiri
If you want to store them for a longer period, freezing is an excellent option. Wrap each onigiri in plastic wrap securely and place them in a freezer-safe bag. They can be frozen for up to a month. When you’re ready to eat, thaw them overnight in the fridge before reheating. This way, your Spicy Tuna Onigiri retains its flavor and texture, making each bite as enjoyable as the first.
Variations of Spicy Tuna Onigiri:
Exploring variations of spicy tuna onigiri can elevate your culinary experience. For instance, consider adding pickled vegetables for a tangy crunch or avocado for creaminess.
