Total time: 40 min
Ingredients: 2 cups Japanese short-grain rice, uncooked; 2 1/2 cups water; 2 tablespoons rice vinegar; 1 teaspoon sugar; 1/2 teaspoon salt; 4 sheets nori (dried seaweed); 8 slices cooked bacon or ham; 1 cup cooked chicken, sliced or shredded; 4 leaves lettuce, washed and dried; 1 medium cucumber, sliced into thin strips; 1 medium carrot, julienned; 2 large eggs, fried or scrambled; 2 tablespoons soy sauce; 2 tablespoons mayonnaise

Onigirazu Recipe tastes like the perfect mashup of a sushi roll and a hearty sandwich: salty, savory, a little tangy, and very satisfying. It works well for busy folks who want a portable lunch or snack in under 40 minutes from start to finish. I first packed these for a road trip and my kids traded away their chips to get extra pieces, which still makes me weirdly proud.

Why Choose This Onigirazu Recipe

This Onigirazu Recipe keeps things simple, flexible, and weeknight friendly. You use basic pantry items like canned tuna or leftover chicken, and you can swap fillings based on what you already have in the fridge.

The method stays very forgiving, so beginners feel comfortable and more experienced cooks still enjoy playing with flavor combos. You also skip the special sushi mat and just use plastic wrap and your hands.

Ingredients You’ll Need

Rice & Seasoning

2 cups uncooked short-grain Japanese rice
- Use sushi rice or Calrose rice. Avoid long-grain rice because it turns out too dry and loose.
2 ¼ cups water for cooking rice
3 tablespoons rice vinegar
- Seasoned rice vinegar works well and saves time since it already includes sugar and salt.
1 tablespoon sugar
1 teaspoon fine sea salt

Nori & Wrapping

4 large sheets nori (full-size sushi nori)
- Choose good-quality, dark green nori. Thicker sheets hold up better when you pack Onigirazu for lunch.
Plastic wrap
Clean kitchen scissors (optional, for trimming nori)

Protein Filling Options

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

Tuna mayo filling
- 1 can tuna in water, drained well
- 2–3 tablespoons Japanese mayonnaise (Kewpie gives the most classic flavor)
- 1 teaspoon soy sauce
- ½ teaspoon lemon juice or rice vinegar
Chicken or turkey option
- 1 cup finely chopped cooked chicken or turkey
- 2–3 tablespoons mayonnaise
- 1 teaspoon soy sauce
Egg option
- 2 large eggs, scrambled or made into a thin omelet and sliced
- Pinch of salt and pepper

You can mix and match these fillings. I often use half tuna mayo and half egg in one Onigirazu.

Veggie & Flavor Add-ins

Use what you like and what you already have.

½ small cucumber, cut into thin sticks
1 small carrot, peeled and cut into thin matchsticks
4–6 leaves green leaf lettuce or romaine, washed and dried
1 small avocado, sliced
2–3 tablespoons pickled vegetables
- Pickled ginger, takuan (pickled daikon), or kimchi work nicely.
1–2 tablespoons furikake rice seasoning
- Any flavor works; I like nori and sesame or egg furikake.
Soy sauce or tamari, to taste
Sriracha, Japanese chili oil, or spicy mayo, to taste

Pantry Shortcuts & Substitutions

Use microwaveable sticky white rice if you feel short on time, just season it with vinegar, sugar, and salt.
Swap Japanese mayo with regular mayo plus a tiny pinch of sugar for similar flavor.
Use canned salmon instead of tuna if you prefer.
Use baby spinach or shredded cabbage instead of lettuce.

Equipment

Rice cooker or medium saucepan with lid
Small bowl for seasoning the rice
Mixing bowl for fillings
Cutting board
Sharp knife
Plastic wrap
Measuring cups and spoons

Tips & Tricks

Rinse the rice 3 to 4 times until the water runs mostly clear so the grains cook up shiny and sticky, not gummy.
Let the cooked rice cool until just warm before you handle it so it stays sticky but does not steam the nori too fast.
Keep a small bowl of water nearby and lightly wet your fingers when you handle the rice so it does not cling to your hands.
Do not overload the fillings; a thinner, even layer wraps more easily and slices more cleanly.
Place the nori shiny side down so the pretty side faces out after you fold.
Press gently but firmly when you wrap so the rice sticks together without smashing the fillings flat.
Slice with a very sharp, slightly damp knife and wipe the blade between cuts for clean halves.
Pack Onigirazu tightly in a lunchbox so they do not slide around and open.
Use leftover rice from dinner and warm it slightly in the microwave before seasoning to save time.
Taste the fillings before you add them and adjust salt, soy sauce, or spice so each bite carries enough flavor.

How to Make Onigirazu Recipe

Step 1: Cook and Season the Rice

Rinse the rice under cold water, swishing with your hand, and drain. Repeat until the water looks mostly clear.
Add the rinsed rice and 2 ¼ cups water to a rice cooker or saucepan. Cook according to your rice cooker instructions, or bring to a boil on the stove, cover, lower the heat, and simmer about 15 minutes until the water absorbs.
Turn off the heat and let the rice sit covered for 10 minutes so the grains finish steaming.
In a small bowl, mix rice vinegar, sugar, and salt until they dissolve.
Transfer the hot rice to a wide bowl, drizzle the vinegar mixture over the top, and gently fold with a rice paddle or spatula. Spread the rice slightly and let it cool until warm, not hot.

Step 2: Prepare the Fillings

For tuna mayo, mix drained tuna, Japanese mayo, soy sauce, and lemon juice in a bowl until creamy. Taste and adjust seasoning.
For chicken or turkey, stir chopped meat with mayo and soy sauce. Add a tiny splash of vinegar if you want more brightness.
Cook the eggs as a soft scramble or thin omelet, season with salt and pepper, and slice into strips.
Slice cucumber, carrot, and avocado. Wash and dry lettuce leaves very well so extra moisture does not soak the nori.
Set all fillings near your work area so you can assemble quickly.

Step 3: Set Up the Nori and Rice Base

Lay a sheet of plastic wrap on your cutting board, slightly larger than the nori sheet.
Place one nori sheet on the plastic wrap in a diamond shape, with a corner pointing toward you. Shiny side faces down.
Wet your fingers lightly, then scoop about ½ cup of warm rice into the center of the nori.
Shape the rice into a square about 3 to 4 inches wide, keeping it even and not too thick.

Step 4: Add Fillings

Sprinkle a little furikake over the rice square if you use it.
Add a layer of lettuce on top of the rice. This layer acts like a barrier and helps keep the nori from getting soggy.
Spoon a few tablespoons of tuna mayo or your chosen protein on top and spread it gently into a square that stays slightly smaller than the rice base.
Add veggies like cucumber, carrot, avocado, and any pickled vegetables in a flat layer.
If you use egg, place the egg strips on top. Drizzle a tiny bit of soy sauce or spicy mayo if you like extra flavor.
Finish with another thin layer of rice, about ¼ to ⅓ cup, and press lightly so it covers the fillings.

Step 5: Fold the Nori

Use the plastic wrap to help you. Lift the bottom corner of the nori up and over the rice stack toward the center.
Lift the top corner down over the center, then fold the left and right corners in, like you wrap a present.
Press gently so the nori sticks to the rice and forms a neat square.
Wrap the plastic wrap tightly around the Onigirazu and twist the ends to seal.
Let it sit for 5 to 10 minutes so the nori softens slightly and the rice sticks together.

Step 6: Slice and Serve

When you feel ready to serve, place the wrapped Onigirazu seam side down on the cutting board.
Use a sharp knife and cut through the center diagonally or straight across. Wipe the blade and dampen it slightly between cuts if the rice sticks.
Keep the halves wrapped until you eat or pack them so they hold their shape.
Repeat the process with the remaining nori sheets, rice, and fillings.

What to Serve with it?

Onigirazu pairs nicely with a simple miso soup, a small bowl of edamame, or a crisp cucumber salad. You can add sliced fruit like oranges, apples, or grapes for a fresh, sweet contrast. Kids enjoy it with a side of carrot sticks and hummus or a small green salad. A cup of hot green tea or iced barley tea rounds out the meal without overpowering the flavors.

Storage Options

Keep freshly made Onigirazu at room temperature for up to 2 hours, then move them to the fridge.
Store wrapped tightly in plastic wrap, then place in an airtight container in the fridge for up to 24 hours for best texture.
If you need longer storage, freeze tightly wrapped Onigirazu without fresh cucumber or lettuce for up to 1 month, since those veggies turn watery.
Thaw frozen Onigirazu in the fridge overnight, then let them sit at room temperature for 20 to 30 minutes before eating.
Reheat fillings that taste good warm, like chicken or egg versions, by unwrapping, covering loosely, and microwaving on low power for short bursts, then rewrap and let them rest so the heat distributes evenly.
