Ingredients
- 2 cups sushi rice
- 2 1/2 cups water
- 1/4 cup rice vinegar
- 2 tablespoons sugar
- 1 teaspoon salt
- 4 sheets nori (seaweed)
- 1/2 cup cooked protein (chicken, tuna, or tofu)
- 1/2 cup sliced vegetables (cucumber, avocado, or carrots)
- Soy sauce (for serving)
- Sesame seeds (optional)
How to Make It
Rinse and cook the rice. Rinse the sushi rice under cold water until the water runs clear. Combine the rice and water in a rice cooker and cook according to the manufacturer’s instructions.
Season the cooked rice. In a small saucepan, heat the rice vinegar, sugar, and salt over medium heat until dissolved. Mix this with the cooked rice and let it cool.
Layer the filling. Lay a sheet of nori shiny side down on a clean surface. Place a scoop of rice in the center, then layer your choice of protein and vegetables on top.
Fold the sandwich. Fold the nori over the filling into a square shape, sealing the edges. Press gently so the package holds together without crushing the filling.
Slice and serve. Slice in half and serve with soy sauce and sesame seeds. Enjoy your Onigirazu Rice Sandwich!
How to Serve It
- Serve the onigirazu with soy sauce for dipping or drizzling.
- Sprinkle sesame seeds over the cut side for extra texture and a nutty finish.
- Pair it with a simple salad, fresh fruit, or a light vegetable side dish for a more complete meal.
- Wrap each sandwich individually for an easy packed lunch or picnic.
How to Store It
For the best texture, enjoy onigirazu soon after assembling. If you have leftovers, wrap each sandwich tightly and store it in the refrigerator.
Refrigeration can make sushi rice firmer, so allow the sandwich to sit briefly before serving. If reheating is necessary, remove the nori first and warm the rice and filling gently, then reassemble or serve without reheating the nori. Freezing is not ideal because the vegetables and nori may lose their texture after thawing.
Helpful Tips
- Rinse the sushi rice until the water runs clear to help remove excess surface starch and improve its texture.
- Let the seasoned rice cool before assembling so the nori stays firm and the fillings remain fresh.
- Avoid overfilling the center. A moderate layer of rice, protein, and vegetables makes folding and sealing much easier.
- Place the nori shiny side down so the finished sandwich has a neat, attractive outer surface.
- Press the folded edges gently but firmly to help the square hold together before slicing.
Optional Variations
- Use chicken, tuna, or tofu as the cooked protein, depending on your preference.
- Swap the vegetables among cucumber, avocado, or carrots to create different textures and flavors.
- Add sesame seeds before folding for extra nuttiness, or serve them on top with soy sauce.
- For a richer sandwich, combine tuna or chicken with a creamy dressing before adding it to the rice.
Frequently Asked Questions
What is onigirazu?
Onigirazu is a Japanese rice sandwich made by wrapping seasoned rice and fillings in a sheet of nori. It has a flat, square shape and can be sliced like a sandwich.
Can I use brown rice instead of sushi rice?
This recipe is designed for sushi rice, which is sticky enough to hold the sandwich together. Other rice varieties may not bind as well.
Can I prepare onigirazu ahead of time?
Yes, you can assemble it ahead of serving, but it is best enjoyed soon after preparation for the freshest nori and vegetables.
Which protein works best in this recipe?
Chicken, tuna, and tofu all work well. Choose a cooked protein that complements the fresh vegetables and seasoned rice.
Why is my onigirazu falling apart?
It may be overfilled, or the rice may not be sticky enough. Use a moderate amount of filling and fold the nori firmly around the center.
