Ingredients

For this Spicy Tuna Onigiri recipe, you’ll need the following ingredients:

Cooked Short-Grain Rice: Essential for its sticky texture that helps hold the onigiri shape.
Nori (Roasted Seaweed): Wraps the rice ball for flavor and texture. It also provides a crisp contrast to the creamy filling.
Salt: Enhances the natural flavor of the rice and filling.
Black Sesame Seeds (optional): Adds a bit of crunch and flavor, but it’s optional.
Water: Used to moisten the rice paddle or spatula to prevent rice from sticking.

Spicy Tuna Filling:

Canned Tuna (in oil): Tuna packed in oil adds a rich, smooth texture and better flavor compared to tuna in water.
Japanese Mayo (Kewpie mayo): Provides a creamy, tangy flavor that complements the tuna.
Sriracha Sauce: The spicy component that gives the onigiri its signature heat.

Alternative Ingredient Suggestions

Tuna Substitute: If you don’t have canned tuna in oil, you can use tuna in water, or even canned salmon for a different flavor.
Mayo Swap: If you can’t find Japanese mayo, regular mayonnaise will work, though it won’t have the same richness.
Spice Level: To make it less spicy, simply omit the sriracha sauce or adjust the amount according to your preference.

Step-by-Step Instructions

Start by transferring freshly cooked rice or warmed leftover rice to a large bowl. Season the rice with salt, then cover and keep it warm.
Open a can of tuna, strain out the liquid, and press with a fork to remove as much liquid as possible.
In a small bowl, mix the strained tuna with Japanese mayo and sriracha sauce to create the spicy tuna filling. Set it aside.
Lay out a large sheet of plastic wrap and moisten your rice paddle or spatula with water. Divide the rice into four equal portions.
Take one portion of rice (about ¾ cup) and flatten it into a circle on the plastic wrap, about ½-inch thick.
Scoop one portion of the spicy tuna mixture and place it in the center of the rice.
Lift the plastic wrap and form the rice into a ball, then shape it into a triangle using the “L” shape between your thumb and index finger.
Cut a sheet of nori into strips. Stick one strip of nori to the bottom of the rice ball.
Garnish with black sesame seeds if desired, and serve immediately.

Tips & Tricks

Rice Consistency: For the best texture, use freshly cooked rice. If you use leftover rice, reheat it and ensure it’s moist enough to stick together.
Avoid Soggy Nori: Don’t remove nori from the packaging until just before assembling. Exposure to air can make the seaweed soggy.
Shaping: Use the “L” shape of your fingers to form a firm triangle and ensure the rice ball holds its shape.
Tuna Moisture: Ensure you strain the tuna thoroughly to avoid any excess liquid that can affect the texture of the onigiri.

Pairing Ideas and Variations

Spicy Tuna Onigiri pairs wonderfully with a variety of Japanese side dishes and drinks. Here are a few suggestions:

Soup: Miso soup or a light seafood soup complements the spicy tuna filling.
Salad: A fresh Japanese ginger salad or a simple cucumber salad adds a crisp contrast.
Rice Dishes: Serve with other rice-based dishes like ramen or teriyaki rice bowls for a complete meal.
Side Dishes: You can also pair it with shrimp tempura or karaage for a more indulgent meal.

Variations:

Non-Spicy Version: If you’re not a fan of spice, simply omit the sriracha and enjoy a creamy tuna onigiri.
Vegan Option: Replace the tuna with mashed avocado or a tofu-based filling for a plant-based alternative.
