Can You Freeze Onigiri

Yes, you can freeze onigiri, or Japanese rice balls. Wrap each onigiri tightly in plastic wrap and store them in a freezer bag. When you’re ready to eat one, you can defrost it in the refrigerator or microwave it for a quick meal. Remember to remove the plastic wrap before reheating!

Are you a fan of onigiri, those delicious Japanese rice balls filled with various savory ingredients? Have you ever wondered if you can freeze them to enjoy later? The answer is yes, but there are some important things to keep in mind to ensure that the texture and flavor of your onigiri remains intact.

Firstly, not all onigiri fillings are suitable for freezing. Ingredients like raw fish or vegetables with high water content may not fare well when frozen and thawed. However, fillings like cooked meats, pickled vegetables, or preserved fish can be successfully frozen without compromising their taste and texture.

Knowing which fillings work best will help you plan ahead when making your onigiri for future consumption.

Dos and Don’ts


  • DO choose the right ingredients: When preparing onigiri for freezing, choose ingredients that freeze well, such as cooked rice and fillings like cooked fish, vegetables, or pickles. Avoid ingredients that may become mushy or lose their texture when frozen, such as raw vegetables or delicate toppings.
  • DO assemble the onigiri properly: Shape the cooked rice and desired fillings into onigiri, ensuring they are tightly packed and hold their shape. Use plastic wrap or airtight containers to individually wrap each onigiri or separate them with parchment paper to prevent sticking.
  • DO cool the onigiri: Allow the onigiri to cool completely at room temperature before freezing. Cooling helps prevent condensation and ensures safe freezing.
  • DO use airtight containers or freezer bags: Transfer the wrapped onigiri into airtight containers or sealable freezer bags. This helps prevent freezer burn and preserves the flavors and textures of the onigiri.
  • DO label and date the containers: To avoid confusion and ensure timely consumption, label each container with the date of freezing. This way, you can keep track of the onigiri’s freshness and enjoy them within a reasonable timeframe.


  • DON’T freeze onigiri with delicate toppings: Onigiri with delicate toppings, such as fresh herbs or tempura, may not freeze well. These toppings can become limp or lose their crispness when frozen and thawed. Consider adding these toppings fresh when serving the onigiri.
  • DON’T freeze onigiri for an extended period: While freezing onigiri can help extend their shelf life, it is best to consume them within a reasonable timeframe for optimal taste and texture. Extended freezing can affect the quality of the rice and fillings.
  • DON’T refreeze previously thawed onigiri: It is not advisable to refreeze onigiri that have already been thawed. The repeated freezing and thawing can affect the texture and overall quality of the rice and fillings.
  • DON’T expect the same texture after freezing: It’s important to note that frozen and thawed onigiri may have a slightly different texture compared to when they were freshly made. The freezing process can make the rice slightly firmer or less moist.
  • DON’T freeze onigiri with mayonnaise-based fillings: Onigiri with mayonnaise-based fillings, such as tuna mayo, may not freeze well. The freezing process can affect the texture and consistency of mayonnaise, resulting in a less desirable texture.

Which Onigiri Fillings Can Be Frozen Successfully

If you’re a fan of onigiri and want to save time in the kitchen, it’s worth knowing which fillings can survive the freezer without losing their flavor or texture. Freezing process can be tough on some ingredients, causing them to lose taste and becoming soggy. However, there are a few fillings that are suitable for freezing.

One popular filling that you could freeze is cooked chicken. After cooking the chicken, let it cool down before shredding it into small pieces. Once shredded, add your preferred seasoning like salt or pepper and mix well.

Form them into balls with sticky rice around them before wrapping each piece with cling film. This way, they will keep their shape and remain fresh in the freezer for up to 3 months.

Another filling that works well is canned tuna mixed with mayonnaise and diced onions. Simply mix these ingredients together until they combine evenly before shaping them into balls as usual.

When you’re ready to eat them after being frozen, thaw them out overnight in a fridge then microwave or steam them for a quick snack or lunch option without any taste comparison from freshly made ones.

Tips for Maintaining Onigiri Texture and Flavor When Frozen

To keep your rice balls tasting just as fresh and delicious when reheated, try these tips for maintaining their texture and flavor even after being frozen.

First off, make sure to wrap each onigiri tightly in plastic wrap before placing them in an airtight container or freezer bag. This will prevent any air from getting in and causing freezer burn.

When it comes to freezing techniques, opt for the flash freeze method. Simply place the wrapped onigiri on a baking sheet and pop it into the freezer for about an hour or until they’re firm. Then transfer them to an airtight container or bag. By doing this, you’ll prevent the rice from clumping together and becoming mushy when thawed.

Lastly, consider tweaking your onigiri recipes slightly if you plan to freeze them frequently. For example, add a little extra moisture (such as some cooked vegetables or dashi broth) to ensure that the rice stays moist after freezing and reheating.

You can also experiment with different fillings that are more forgiving when frozen – think canned tuna instead of fresh fish or cooked chicken instead of raw meat.

By following these tips for maintaining your onigiri’s texture and flavor when frozen, you can enjoy these tasty treats anytime you want without sacrificing quality!
