What’s the best method to store cooked rice? Simply freeze the rice in airtight containers and reheat to enjoy later on! This is by far the best approach to keep your rice fresh and moist.

I often get questions from readers about how I store cooked rice. I usually make extra rice so that we always have some extra cooked rice ready at hand. What’s the best way to store cooked rice?

What’s the Best Way to Store Cooked Rice
When you end up with extra rice in your rice cooker after a meal, you have several options to store it.
- Option 1 – Keep in your rice cooker with “keep warm” function on
- Option 2 – Keep at room temperature
- Option 3 – Store in your refrigerator
- Option 4 – Store in your freezer
Which option do you normally use?
From my experience, freezing rice is the best way to store cooked rice, and I freeze cooked rice even if I plan to use it the next day. Here’s why.

3 Reasons Why You Should Freeze Rice
1. Stay moist, fresh, and delicious
There are many Japanese articles online that prove frozen then reheated rice tastes the best (by testing different storage methods).
You might have tried to refrigerate rice, but the texture becomes hard and dry. Unless you have plans to make fried rice the next few days, refrigerated leftover rice doesn’t taste good, even the next day!
With the freezing method, pack up the freshly cooked rice with steam (moisture) in an airtight container and close the lid immediately. So when you reheat the frozen rice, the rice is moist, fresh, and delicious just like freshly cooked rice!
2. Store for up to 1 month
The freezing method allows you to store the cooked rice for up to 1 month, so you don’t feel obligated to use it immediately or for 2-3 days.
Here’s how long the cooked rice last, compared to other storing options.
- Option 1 (rice cooker) – Up to 3 hours (best quality) to 1 day
- Option 2 (room temperature) – Up to 6 hours (summer) to 1 day (winter)
- Option 3 (refrigerator) – 3 days
- Option 4 (freezer) – Up to 1 month
3. Save money and time
If you need to cook rice for just 1 to 2 servings every day, cooking rice every day might not make sense. It’s great that you can eat freshly cooked rice, but it does not save your money and time. And rice tastes better when you cook (at least) 2 cups of rice.
Therefore, I highly recommend making extra rice and freezing it. That way, you can just cook rice when you are running out of frozen rice.

How to Freeze Cooked Rice
1. Pack immediately
Ideally, as soon as the rice is finished cooking, pack away the amount of rice you do not need or plan to keep. Make sure to pack the rice with steam and cover the lid immediately to trap the steam and moisture.
Sometimes, you didn’t plan to leave any leftover rice. In that case, just pack the leftover (you can add some water when you’re reheating).
2. Let cool completely
You do not want to spoil your food in the freezer with your hot/warm rice. So make sure to cool the rice containers first before storing them in the freezer.
3. Put in the freezer
The rice quality will stay well for up to 1 month!

Best Containers for Freezing Cooked Rice
Option 1: Glass container with a lid

I recommend a glass container with a lid such as Pyrex 4-Cup Round Dish Storage Container with a Cover. The 4-cup container fits 2 servings of cooked rice, which is perfect for my children’s lunchbox (2 lunch boxes). Pyrex 2 -Cup Round Dish Storage Container with Cover works great for a single rice bowl portion.
Option 2: Japanese rice container with air vent

In Japanese grocery stores, you might find these plastic containers that are specifically made for freezing and then microwaving rice.
Option 3: Microwave-safe plastic wrap or freezer Bag
This may not be the most environmentally-friendly method with so much plastic usage. However, if your freezer is tiny and cannot fit the glass containers (I used to live in a dormitory with a tiny freezer space), this might be your only option.
Here’s how you prepare the “frozen rice package”. You can use the same method when you use a freezer bag.



How to Reheat the Frozen Rice
1. Use the Microwave

>> To reheat the frozen rice in the glass container…
- Take out the frozen rice container from the freezer.
- Open the lid and loosely cover it with a paper towel.
- Microwave until the rice is hot all the way through.
This particular 4-cup container requires microwaving for 4 minutes (1100 w). You might want to experiment with your microwave to see how long it takes to defrost properly.
>> To reheat the frozen rice in the plastic wrap/bag…
- Defrost the rice package in the refrigerator or on the counter until the plastic wrap comes off.
- Transfer to a bowl/plate.
- Sprinkle a little bit of water to add some moisture.
- Loosely cover it with a paper towel.
- Microwave for 1 ½ to 2 minutes, or until hot all the way through.

2. Use the Steamer
When you need rice, here’s what you need to do:
- Take out the rice from the freezer and open the lid.
- Prepare the steamer using a large pot (See the pictures below).
- Bring the water to a boil and steam the frozen rice in the glass container until the rice is defrosted and warm.

Hi Roxanne! Aww.🥰 Nami and all of us at JOC are so happy to hear that this post, including the photo, was helpful.
Thank you for taking the time to read Nami’s post and providing feedback.
Hey,
When making rice for lunchboxes, do I have to heat it up or defrost before putting in a lunchbox or can I just pack it right from the freezer? I’m going to microwave it later during the day. Also, is it necessary to keep the lunchbox in the fridge until meal time or can I leave in the backpack?
Thank you all for this precious blog!
Hi Lena, Thank you for reading Nami’s post!
If you have a microwave during lunchtime, you can pack the frozen rice with ice packs and warm it up right before your meal. The rice tastes better when it is just warmed up.
You can also warm it up and pack it with other dishes.🙂

Hi. I’ve been wondering what a serving size of rice is in Japan ? I see that 5- 7 serves are recommended by the Japanese health ministry. per day but don’t know the portion sizes are. Or the servings of other components… what size are your rice bowls?
Hi Patrice, Thank you very much for reading Nami’s post!
A typical Japanese rice bowl holds 150 g of steamed rice, and it’s a one-serving amount.
We hope this helps!
I have been freezing all kinds of rice for many years so it’s cool to see that it’s a “Japanese-approved” method, haha! I actually portion my rice into a mini loaf pan, the kind with multiple cavities (mine has nine), and freeze it, then once it’s frozen turn the pan upside down onto a cookie sheet and briefly run warm water over the back. The frozen portions drop out onto the cookie sheet and then I wrap them with aluminum foil – it’s recyclable where I live and as far as I understand is one of the easier materials to recycle. You could keep them in a plastic bag too to prevent freezer burn. When I need one I run a bit of water over the foil and I can unwrap it easily and rinse off the foil for recycling.
Thank you for all the recipes on the site, they’re fantastic!
Hi Elle! We are glad to hear that you enjoyed Nami’s post and all the recipes that she shared.
Thank you for sharing your experience with us! 😊
Thank you for the informative article. For how long approximately would you recommend steaming 1-2 servings of frozen rice?
Hi, thank you for this guide! I don’t have a microwave nor a steamer, and usually heat things up in a pot or pan. How would you suggest reheating the rice in my case?
Hi Arianna! Thank you very much for reading Nami’s post!
You can create a steamer by placing a small dish or Pie/Tart Pan in the pot and filling the pot with water (about 1″~2″ high water level).
We hope this works for you!
Thanks, I’ll try 🙂
Have always loved making bentos for myself and my kids…I have a little collection of bento boxes. Now that the kids are out of the house and I’m retired there is not much occasion to make bentos…I “adopted” my neighbor’s kid for a while just so I could make her bentos….jajaja. Love your site and all the inspirational vids and recipes!!! I will be trying the frozen rice suggestions today
Hi Michael! Wow! What a lucky neighbor!😃
Yes! Please try freezing rice. It works really well and saves a lot of time in the morning.
Thank you very much for reading Nami’s post!
Very helpful JOC post. Now I don’t have to throw away so much rice!
Hi Laura! Nami and JOC team are so happy to hear this post was very helpful! ☺️
Thank you for visiting the JOC site and for your kind feedback!
I don’t suppose you have a link to Japanese Rice Container with Air Vent on Amazon JP? I have yet to see them in our local MaruFuji
Hi Michael, Here is the Amazon JP link that we found for you!

I have tried freezing left-over regular rice (not glutinous rice) before and my experience is not very encouraging. When I thaw the frozen rice, water comes out and settles at the bottom and some of the grains appear opaque. After microwaving, the rice turns out broken and grainy even if I sprinkle some water prior to microwaving. The outcome is not very appetizing. This is the first time I encountered this suggestion to freeze rice and would like to try it again. I just do not know what I am doing wrong or if this method only applies to glutinous rice.
Hi Jerry,
When you take out the rice from the freezer, thaw it just enough to remove the wrapper and put it in the microwave to reheat fully. And make sure you cover the rice with a microwave-safe paper towel or cover to keep the moisture.
We use this technic for different types of rice, and it works great for us. We hope you get better results too. 🙂
I don’t freeze my rice. When I reheat my rice, I put a dish over the container (leaving a small gap for air to escape), drizzle a little bit of water over the rice and put a cup of water next to it in the microwave for 2mins. I do get the similar effect of freshly steamed rice.
Hi Dephanie,
That will work well too for the next day.
Thank you for sharing your cooking tips with us!😊
Dear Nami – Your site is a discovery for me – thank you!
I want to ask. If I prepare the rice in for bento box in the evening (8-9 p.m), leave them to cool at room temperature in a tight container and just put them in the bento for my daughter in the morning – will they be good enough for lunch? (There is no possibility to warm up in bento at school). Thank you in advance.
Hi Daiva! Germs like the lukewarm environment, so it’s most dangerous when the food is cooling down and it has that “warm” stage… so if you leave it at room temperature, there is a long period of “warm” food and it can grow bacteria (you just don’t see it). And since there is no way your daughter can heat up in school, there is no way to kill bacteria before consuming. It’s tricky…. I really don’t like putting cooked rice in the refrigerator as rice gets hard. We always pack the rice in the morning, let cool quickly (shorter “warm” period) with ice packs and have kids bring it to school. 🙂
Thank you Nami, will cook the rice in the morning and let them cool with ice cubes as you advised! Unfortunately it is not possible to buy short grain japanese rice in Lithuania, but there are so-called ‘sushi’ rice. This is probably the closest thing you can get?
Hi Daiva! Oh you’re in Lithuania! Wow, thank you so much for trying my recipes from all the way from there! I think, sushi rice is the same as short-grain rice. In Western countries, people call short-grain rice “Sushi Rice”. In Japan, we call sushi rice ONLY when steamed rice is seasoned with sushi vinegar to make all the sushi rolls, etc. 🙂
Thank you, Nami, my daughter (12) is is fascinated by Japan culture, food, movie, fashion etc. The great film by Hayao Miyazaki Spirited Away is her favourite 🙂
So your site for me is a way to get to Japan for a couple of minutes.
Hi Daiva,
We couldn’t be happier to hear how much joy and excitement Nami’s recipe has brought to you and your family! Please check https://www.justonecookbook.com/categories/japanese-culture/ to learn more about Japan as well!
Thank you!
Thank you for the tips on storing cooked rice. Will try it for my next batch of rice.
because i know rice doesnt last long in my house, like to store the rice in a regular container with a wet paper towel and that keeps it from drying up. the rice is usually used with 24 hours.
Hi Racquel! Thanks for sharing your tip with us!
My Japanese mom showed me how to portion cooked gohan straight from the rice cooker, to small snack sized zipper bags …in single portions…making sure I take the air out of the bags. . Then I leave the steamy bags on the counter to cool a little bit, before stacking them in a larger freezer storage bag. Since I’m now the only one in the house still eating rice, this is perfect for me. I now know that I punch in time as 111 on my 1300 watt microwave and voilá…my rice is fresh tasting and the right temperature. And definitely recycling my bags. 👍🏼 I’m loving everyone’s tips and stories.
Hi Margaret! I used to do that in college too, because that’s what most Japanese people do in Japan and it saves space in the freezer… However, people are more conscious about the excessive plastic usage (not so much in Japan, unfortunately) and being careful about putting hot food on plastic, so I have changed my method to a glass container. From my experience using both ways, it’s a lot easier to clean the container (dishwasher safe, too) than washing the Ziploc bag and dry upside down waiting to completely dry. However, freezer space can be an issue… 🙂
