2 cups cooked Japanese short-grain rice (warm, not hot)
1/2 cup cooked chicken breast, finely shredded or chopped
1 tablespoon soy sauce
1 teaspoon sesame oil
1 teaspoon mirin (optional)
1 tablespoon mayonnaise (optional, for creamier filling)
Salt to taste
1–2 sheets nori (seaweed), cut into strips
Toasted sesame seeds, for garnish (optional)
Plastic wrap or damp hands, for shaping

Directions

In a small bowl, mix the shredded chicken with soy sauce, sesame oil, mirin, and mayonnaise if using. Adjust salt to taste.
Divide the warm rice into 4 equal portions.
Place a piece of plastic wrap in your palm (or dampen your hands), then spread one portion of rice into a round or triangular shape.
Add a spoonful of chicken mixture in the center and fold the rice around it, enclosing the filling.
Shape into a firm but gentle triangle or round ball.
Wrap a strip of nori around the bottom for easy handling.
Repeat with the remaining rice and filling.
Garnish with toasted sesame seeds if desired.
Serve right away or wrap tightly for later, ideally eaten the same day.

Variations

Use canned tuna with mayo instead of chicken for a classic tuna onigiri.
Add chopped pickled vegetables for extra flavor and crunch.
Swap nori for shiso leaves for a fresh herbal twist.
Mix furikake seasoning into the rice before shaping.
Use teriyaki chicken for a sweeter, saucier filling.

Storage/Reheating

Onigiri are best eaten the same day they’re made, but you can store them for later. Wrap tightly in plastic wrap and refrigerate for up to 1 day. To reheat, microwave gently for 15–20 seconds with a damp paper towel on top to prevent drying out. If packing in a lunchbox, keep the nori separate and wrap just before eating to maintain crispness.

FAQs

What type of rice is best for onigiri?

Japanese short-grain rice (sometimes labeled sushi rice) works best because it’s sticky and holds its shape.

Can I make chicken onigiri ahead of time?

Yes, you can prepare them in the morning for lunch or refrigerate them overnight, though they’re freshest the same day.

Can I freeze chicken onigiri?

Yes, wrap tightly in plastic wrap and freeze for up to 1 month. Thaw in the fridge before reheating.

Do I need nori to make onigiri?

No, nori is optional. It helps with handling and adds flavor, but you can enjoy them plain or use another wrap like shiso leaves.

Can I use leftover chicken?

Absolutely. Shredded rotisserie chicken or any leftover cooked chicken works well.

How do I stop the rice from sticking to my hands?

Dampening your hands with water or using plastic wrap makes shaping much easier.

What fillings go well with onigiri besides chicken?

Tuna with mayo, salmon flakes, pickled plum (umeboshi), or even vegetables are popular options.

Are chicken onigiri gluten-free?

Yes, as long as you use gluten-free soy sauce and ensure other ingredients are gluten-free.

Can I pack onigiri in a kid’s lunchbox?

Yes, they’re perfect for lunchboxes. Just wrap them well and keep them cool until lunchtime.

How do I keep the nori crisp?

Store the nori separately and wrap it around the rice ball just before eating.
