Ingredients

These ingredients come together to form Spicy Tuna Onigiri—handheld, flavorful, and quick to assemble. I like keeping the rice fluffy, the filling creamy, and the nori crisp. Exact quantities are printed at the bottom for printing and shopping lists.

• 3 cups cooked Japanese short-grain rice — fluffy, slightly sticky, the perfect base.
• 1 can tuna (5 oz), drained — classic protein for the creamy filling.
• 3 tablespoons mayonnaise (preferably Japanese mayo) — binds the filling with velvety richness.
• 1–2 teaspoons sriracha — adds the signature spicy kick; adjust to taste.
• ½ teaspoon soy sauce — a touch of salt and umami.
• ½ teaspoon sesame oil — gives a nutty aroma.
• 1 teaspoon sesame seeds — for crunch and a toasty note.
• Salt, to taste — helps wake up the flavors.
• 4–6 sheets roasted nori, cut into strips — wraps the onigiri and keeps hands clean.

Optional: For gluten-free diets, use gluten-free soy sauce or tamari. If you don’t have Japanese mayo, you can use regular mayo or add a splash of yogurt for tang, though that will change the creaminess slightly.

What you’ll need for Spicy Tuna Onigiri

I’ll list the core components with quantities here, so you can print a shopping-friendly version. 3 cups cooked Japanese short-grain rice, warm; 1 can tuna (5 oz), drained; 3 tablespoons mayonnaise (Japanese mayo preferred); 1–2 teaspoons sriracha; ½ teaspoon soy sauce; ½ teaspoon sesame oil; 1 teaspoon sesame seeds; salt to taste; 4–6 sheets roasted nori, cut into strips. Optional: gluten-free tamari and extra sesame seeds.

Substitutions and pantry tips for Spicy Tuna Onigiri

For gluten-free diets, swap soy sauce with tamari or coconut aminos. If you’re dairy-free, use dairy-free mayo or mashed avocado for creaminess. Want extra heat? add a pinch more sriracha or a drop of chili oil. Tuna in oil or water both work; drain well for the best texture.

How to Make Spicy Tuna Onigiri

Step 1: Make the Spicy Tuna Onigiri filling

I mix the Spicy Tuna Onigiri filling by blending tuna, mayonnaise, and sriracha until creamy.

I add soy sauce, sesame oil, and sesame seeds for depth and aroma.

I taste and adjust heat to suit my family’s tolerance, keeping the balance bright.

This creamy filling should be spreadable but not runny, easy to scoop with a damp spoon.

Quick filling tip

Use a damp spoon or spatula to blend smoothly and keep the texture cohesive.

Step 2: Shape the Spicy Tuna Onigiri rice

With damp hands, I portion warm rice and shape it into balls or triangles.

Handle gently so the grains stay fluffy and cling just enough to hold together.

If the rice cools, wrap in a damp towel for a minute to revive the stickiness.

Preservation and handling

Keep hands wet to prevent sticking, and cover with a damp cloth between steps.

Step 3: Fill and seal the Spicy Tuna Onigiri

Make a small indent in each rice ball, add 1–2 teaspoons of filling, and cover with more rice.

Gently press to seal the filling inside, forming a tidy ball or triangle.

Seal edges well so the filling stays centered and the rice stays intact.

Seal integrity tips

Pack so the filling stays centered and the rice doesn’t crack during shaping.

Step 4: Wrap with nori and serve

Wrap the bottom with a strip of roasted nori; this makes the handheld Japanese snack easy to grip.

Serve immediately or wrap tightly for later, and enjoy in lunch boxes or on the go.

Tips for Success

• Spicy Tuna Onigiri timing matters; use warm rice for softer texture and better shaping.
• Keep moisture balanced; too wet filling soggy, too dry rice cracks.
• Prep with damp hands and a damp towel to prevent sticking.
• Gently handle the rice; press edges to seal without squashing grains.
• Taste the filling before shaping; adjust sriracha and soy for balanced heat.
• Cool rice briefly if needed, then re-warm gently for best stickiness.

Spicy Tuna Onigiri timing and texture tips

Spicy Tuna Onigiri shines when the rice is just warm. Keep the filling balanced with mayo and sriracha so it stays creamy, not runny. Handle gently to preserve fluffy grains and a tidy shape.

Common mistakes to avoid with Spicy Tuna Onigiri

Overfilling or pressing too hard tears rice and hides the filling. Not keeping hands wet makes the rice crack. Skipping the nori wrap can cut grip and flavor. Make a little indent and seal well.

Equipment Needed

• Sharp knife and cutting board
• Damp cloth or bowl of water for wet hands

Alternative tools that still deliver results: a clean silicone mat instead of parchment, resealable bags for portioning, a damp towel to speed shaping, and a compact knife set. These save space and cleanup while you stay on schedule.

Variations

• Spicy Tuna Onigiri with avocado and cucumber

  • Creamy avocado folds into tuna mayo for extra silkiness, making the filling feel luxurious.
  • Thin cucumber spears add crisp, refreshing texture that contrasts with soft rice.
  • Lightly reduce mayo if using avocado so the mix stays scoopable, not runny.
