Ingredients You’ll Need

Rice & Seasoning

2 cups uncooked short-grain Japanese rice

2 1/4 cups water for cooking rice
3 tablespoons rice vinegar
1 tablespoon sugar
1 teaspoon fine sea salt

Nori & Wrapping

4 large sheets nori (full-size sushi nori sheets)
- Choose roasted nori labeled “yaki nori” for better flavor.

Protein Options

Pick one or mix a couple. This recipe makes about 4 large onigirazu.

1 large chicken breast, cooked and sliced thin
- Rotisserie chicken works great as a shortcut.
or 1 can tuna (5–6 ounces), drained and mixed with 2–3 tablespoons Japanese mayo and a pinch of salt
or 4 slices thick-cut spam, pan-seared until browned
or 4–6 strips crispy bacon
or 1 block firm tofu, pressed, sliced, and pan-seared with soy sauce

Veggies & Extras

1 small cucumber, sliced into thin sticks
1 medium carrot, peeled and cut into matchsticks or shredded
1 small avocado, sliced
4 leaves lettuce (romaine, green leaf, or butter lettuce)
2–3 tablespoons Japanese mayo (Kewpie gives the most classic flavor)
1–2 tablespoons soy sauce or tamari
1 teaspoon toasted sesame oil
1 tablespoon toasted sesame seeds (white or black)
Optional: quick pickled veggies like pickled daikon, kimchi, or pickled red onion

Optional Flavor Boosters

Sriracha or chili crisp for heat
Furikake seasoning for extra umami
A little wasabi mixed into mayo if you like a kick

Equipment

Rice cooker or medium saucepan with lid
Small bowl for seasoning the rice
Cutting board
Sharp knife (a slightly wet blade slices cleaner)
Plastic wrap or parchment sheet for easier folding and less mess

Tips & Tricks

Rinse the rice until the water runs almost clear so the grains cook fluffy and not gummy.
Season the rice while it still feels warm so it absorbs the vinegar mixture evenly.
Keep your hands slightly wet when handling rice so it does not stick everywhere.
Do not overload the fillings or the nori will tear and the square will not close well.
Place the nori shiny side down so the pretty side faces out on the finished onigirazu.
Press each layer gently with your hands to compact it so the square slices neatly.
Wrap each onigirazu tightly in plastic wrap and let it sit 5–10 minutes before slicing so it holds shape.
Wipe or wet the knife between cuts so the rice does not cling and smear.
Prep a few different fillings at once so you build a mini assembly line and save time.

How to Make Onigirazu Recipe

Cook and Season the Rice

Rinse the rice under cold water, swishing with your hand, and drain several times until the water looks mostly clear.
Add the rinsed rice and 2 1/4 cups water to a rice cooker or saucepan, then cook according to your rice cooker instructions or bring to a boil, cover, lower heat, and simmer about 15 minutes.
While the rice cooks, mix rice vinegar, sugar, and salt in a small bowl until the sugar dissolves.
When the rice finishes, fluff it into a wide bowl, drizzle the vinegar mixture over the top, and fold gently with a rice paddle or spatula until the grains look glossy and evenly seasoned. Let it cool until just warm, not hot.

Prep Fillings

Slice cooked chicken, spam, tofu, or other protein into thin strips.
Stir canned tuna with Japanese mayo and a pinch of salt until creamy.
Wash and dry lettuce leaves, then slice cucumber and carrot into thin sticks and cut avocado into slices.
Stir soy sauce, sesame oil, and sesame seeds together for a quick drizzle sauce if you want extra flavor.

Set Up the Wrapping Station

Lay a square of plastic wrap or parchment on your cutting board.
Place one sheet of nori in the center, rotated like a diamond so a corner points toward you.
Keep a small bowl of water nearby so you can wet your fingers while handling rice.
Arrange your fillings within reach so you move quickly and keep the rice from drying out.

Build the Rice Sandwich

Scoop about 1/2 cup of warm rice into the center of the nori and shape it into a small square, leaving several inches of nori visible on all sides.
Add a leaf of lettuce on top of the rice, then layer your protein, veggies, and any extras like avocado, pickles, or furikake.
Drizzle a little soy mixture or Japanese mayo over the fillings, but keep it light so nothing leaks.
Add another 1/3 to 1/2 cup rice on top and gently press it into a square that matches the base layer.

Fold and Wrap

Take the bottom corner of the nori and fold it up over the rice stack, then press gently.
Fold the right corner over, then the top corner down, and finally the left corner, so you form a tight little square.
Use slightly wet fingers to press and seal any edges that feel loose.
Wrap the whole square tightly in plastic wrap or parchment and press lightly with your hands to compact it.

Rest and Slice

Let the wrapped onigirazu sit for 5–10 minutes so the nori softens and the rice and fillings settle.
When you feel ready to serve, place the square on the cutting board and slice it in half with a sharp, slightly wet knife.
Cut straight through in one motion without sawing so the layers stay clean and pretty.
Serve the halves cut side up so everyone can see the colorful layers inside.

What to Serve with Onigirazu Recipe

This Onigirazu Recipe pairs nicely with a simple miso soup or a light veggie soup for a cozy meal. Add a side of edamame, sliced fruit, or a small green salad to round things out without much extra work. Kids often love it with cucumber sticks and a little soy sauce for dipping. You can also pack it with iced green tea, sparkling water, or a fruit smoothie for a fresh, balanced lunch.

Storage Options

Store leftover onigirazu tightly wrapped in plastic or in an airtight container in the fridge for up to 24 hours for best texture.
Keep avocado-free versions in the fridge up to 2 days, since avocado browns faster.
Freeze tightly wrapped onigirazu that do not contain fresh lettuce or cucumber for up to 1 month, then thaw in the fridge overnight.
Reheat warm-style fillings by microwaving the wrapped onigirazu for 20–30 seconds or until just slightly warm, or enjoy it straight from the fridge for a cool, sushi-style bite.
