Step‑by‑Step Instructions for Spicy Tuna Onigiri Recipe

Step 1: Prepare the Rice
Begin by rinsing 2 cups of sushi rice under cold water until the water runs clear, removing excess starch for the perfect texture. In a rice cooker or pot, combine the rinsed rice with 2 ½ cups of water and cook according to package directions, usually about 18-20 minutes. Once cooked, let the rice cool for about 10 minutes, ensuring it remains slightly warm and sticky, ideal for shaping the onigiri.

Step 2: Season the Rice
In a small bowl, whisk together 2 tablespoons of rice vinegar, 1 tablespoon of sugar, and 1 teaspoon of salt until fully dissolved. Gently fold this mixture into the cooled sushi rice using a wooden spatula or rice paddle, being careful not to mash the grains. The seasoned rice should have a subtle shine and be flavorful, ready to form the base for your Spicy Tuna Onigiri.

Step 3: Make the Filling
In a mixing bowl, flake one 5-ounce can of tuna using a fork, breaking it down into fine pieces for an even texture. Add 2 tablespoons of mayonnaise, 1 tablespoon of sriracha (or more to taste), 1 teaspoon of sesame oil, and 1 teaspoon of soy sauce (or tamari for gluten-free). Mix well until all ingredients are combined, and fold in 1 finely chopped green onion if using. The filling should be creamy with a spicy kick.

Step 4: Shape Onigiri
Wet your hands with water to prevent the rice from sticking. Take a handful of the seasoned rice (about ½ cup), and flatten it slightly in your palm to create a small well in the center. Spoon a generous portion of the tuna filling into the well, then carefully mold the rice around the filling to encase it. Use your hands to press the rice into a firm triangle shape, ensuring it holds together well.

Step 5: Wrap and Serve
Cut nori sheets into strips, then wrap each formed onigiri with a strip of nori, which adds flavor and makes them easy to handle. For the best texture, serve your Spicy Tuna Onigiri immediately while still slightly warm. If not serving right away, keep them covered with a damp cloth to maintain moisture without making the rice mushy. Enjoy your delightful and convenient homemade meal!

Expert Tips for Spicy Tuna Onigiri

Prevent Sticking: Use wet hands when shaping the onigiri to avoid the rice sticking to your fingers. Just a light wetting will do!

Warm Rice Only: Shape the rice when it’s warm but not hot to make molding easier and prevent burns. This helps achieve the perfect Spicy Tuna Onigiri texture.

Gentle Pressure: Don’t compress the rice too tightly. Using gentle pressure ensures light and fluffy onigiri instead of dense, hard balls.

Customizable Fillings: Feel free to swap out tuna for other proteins or veggies, making the recipe easily adaptable to suit any dietary preference.

Good Storage: If making ahead, wrap each onigiri individually in plastic wrap to keep them fresh. They can stay good for up to two days.

How to Store and Freeze Spicy Tuna Onigiri

Fridge: Keep wrapped Spicy Tuna Onigiri in an airtight container or wrapped in plastic for up to 2 days to maintain freshness and texture.

Freezer: For longer storage, freeze the wrapped onigiri in a freezer-safe bag for up to 1 month. Thaw in the fridge overnight before serving.

Reheating: To reheat, steam the onigiri for about 5 minutes or microwave them for a few seconds, ensuring they stay moist. Avoid heating too long to preserve the rice’s texture.

Make-Ahead Tips: Prepare the sushi rice and filling in advance, storing them separately. Assemble the onigiri just before serving for the best taste and quality.

Make Ahead Options

These Spicy Tuna Onigiri are perfect for meal prep enthusiasts! You can prepare the sushi rice and the tuna filling up to 24 hours in advance. Simply cook and season the sushi rice as directed, then let it cool completely before storing it in an airtight container in the refrigerator. For the filling, combine the flaked tuna, mayonnaise, sriracha, sesame oil, and soy sauce (or tamari) in a bowl, mixing well, and refrigerate it separately. To maintain quality, keep the rice and filling separate until you’re ready to serve. When you’re ready to enjoy your onigiri, simply shape them and wrap with nori for a fresh, delicious meal that’s just as delightful as when made fresh!

Spicy Tuna Onigiri Recipe FAQs

What type of tuna should I use for the filling?
Absolutely! I recommend using canned tuna in water or olive oil for the best flavor and texture. Just make sure to drain it well before mixing it into your filling for a creamy consistency.

How do I know if my sushi rice is properly cooked?
Very importantly, sushi rice should be tender yet slightly sticky to hold together when shaped. It typically cooks in about 18-20 minutes. If the grains feel overly soft and mushy, you may have added too much water or overcooked it. Rinsing the rice until the water runs clear helps prevent this!

Can I store Spicy Tuna Onigiri in the refrigerator?
Of course! Once wrapped in plastic or placed in an airtight container, your Spicy Tuna Onigiri can be stored in the fridge for up to 2 days. Just remember to keep them tightly covered to maintain that delightful texture—nobody likes a dry rice ball, right?

What’s the best way to freeze Spicy Tuna Onigiri?
To freeze, start by individually wrapping each onigiri in plastic wrap, then place them in a freezer-safe bag. They’ll stay fresh for up to 1 month. When you’re ready to enjoy, simply thaw them in the fridge overnight! Reheat them gently by steaming for about 5 minutes so they don’t dry out.

Can I customize the filling if I have allergies?
Absolutely! You’re free to get creative here. If you’re allergic to tuna, try using cooked salmon, shredded chicken, or even seasoned chickpeas for a plant-based twist. Just be sure that whatever replacement you opt for still complements the rice’s overall flavor.

What’s the best way to ensure my onigiri doesn’t fall apart?
Great question! When shaping the onigiri, make sure to use slightly warm rice and apply gentle pressure as you form them into triangles. Using wet hands helps, too! This technique keeps the rice loose and fluffy while forming strong enough shapes to hold the filling without breaking.
