Onigiri, or Japanese rice balls, are a delightful and versatile snack that can be enjoyed at any time of the day. These handheld treats are perfect for picnics, lunchboxes, or a quick bite on the go. With a simple combination of seasoned rice and nori, onigiri offers a taste of Japan's culinary tradition in every bite.
When preparing onigiri, you might need to visit a specialty store or the international aisle of your supermarket for a few key ingredients. Japanese short-grain rice is essential for the right texture and stickiness. Additionally, nori (seaweed) is used to wrap the rice balls, adding a savory flavor and making them easier to handle.

Ingredients For Onigiri Japanese Rice Balls
Japanese short-grain rice: This type of rice is sticky and holds together well, making it ideal for shaping into onigiri.
Water: Used to cook the rice to the perfect consistency.
Salt: Adds flavor to the rice and helps in seasoning.
Nori: Seaweed sheets cut into strips, used to wrap the rice balls for added flavor and ease of handling.
Technique Tip for Making Onigiri
When shaping the rice into onigiri, make sure your hands are adequately moistened. This prevents the rice from sticking to your hands and allows you to form a more compact and cohesive shape. Additionally, using a light sprinkle of salt on your hands not only adds flavor but also helps in preserving the onigiri.

How to Store and Freeze Onigiri
Allow the onigiri to cool completely before storing. This prevents condensation, which can make the rice soggy.
Wrap each rice ball individually in plastic wrap. This keeps them fresh and prevents them from sticking together.
Place the wrapped onigiri in an airtight container. This adds an extra layer of protection against moisture and odors.
Store the container in the refrigerator if you plan to consume the onigiri within a couple of days. They can last up to 3 days when properly stored.
For longer storage, place the wrapped onigiri in a freezer-safe bag. Squeeze out as much air as possible before sealing to prevent freezer burn.
Label the bag with the date so you can keep track of how long they've been stored. Frozen onigiri can last up to a month.
To reheat, remove the plastic wrap and microwave the onigiri on medium power for 1-2 minutes. If reheating from frozen, you may need to microwave for an additional minute or two.
Alternatively, you can steam the onigiri for a few minutes until heated through. This method helps retain the original texture of the rice.
If you prefer a crispy exterior, lightly pan-fry the onigiri in a bit of sesame oil after thawing. This adds a delightful crunch and enhances the flavor.
Always check the onigiri for any off smells or discoloration before consuming, especially if they've been stored for an extended period.
How to Reheat Leftovers
Microwave method:
- Place the onigiri on a microwave-safe plate.
- Cover with a damp paper towel to keep the rice moist.

Steaming method:
- Set up a steamer with water and bring it to a boil.
- Place the onigiri in the steamer basket, ensuring they are not touching each other.

Pan-frying method:
- Heat a non-stick skillet over medium heat and add a small amount of vegetable oil.
- Place the onigiri in the skillet and cook for 2-3 minutes on each side until they are crispy and heated through.
- Optionally, brush with a bit of soy sauce for added flavor.
Oven method:
- Preheat your oven to 350°F (175°C).
- Wrap each onigiri in aluminum foil to prevent drying out.
- Place them on a baking sheet and heat for 10-15 minutes.
Boiling method:
- Bring a pot of water to a gentle boil.
- Place the onigiri in a heatproof plastic bag and seal it tightly.
- Submerge the bag in the boiling water for 5-7 minutes until heated through.
