How long can rice stay in a rice cooker? It all depends on how long you’ve cooked it. If your rice is still warm, you can leave it in the cooking bowl until you need to use it again, or you can transfer it to an airtight container and store it in the fridge for up to two days before reheating.


If your rice has cooled down, don’t transfer it to an airtight container because this will just prolong its exposure to the air and cause spoilage over time.



When Is It Safe to Eat Leftover Rice?

There’s nothing like a plate of fluffy, steaming rice to fill you up. And leftovers are convenient if you don’t have time to cook again from scratch. But how long can rice stay in your rice cooker and still be safe to eat?

When Are There Signs of Mold on Rice?

There are a few different ways to tell if there is mold on rice. The most obvious way is to smell it, if there is an off-putting odor it may be due to mold. Next, do not forget to look at your rice very closely and check for dark black spots.


Do not eat rice with any sign of mold or just don’t buy that specific kind of rice anymore. Finally, you should give all your uncooked rice one final rinse before cooking it even if you think that it looks clean, because you never know when bacteria could have developed on some previously overlooked spot.


Does the Color of Stale Rice Affect Its Safety?


One of my rice-obsessed friends had an interesting question about rice safety: does rice that turns yellow or brown stay safe to eat? The short answer is yes but I’m hoping to get into more detail, because when it comes to food safety and cooking, color can be deceiving.

Storage Tips for Long-Term Use


If you’re storing rice for longer than two weeks, transfer it to an airtight container with as little air in it as possible. Store your container at room temperature and be sure to check on your rice every month or so.


If you notice any moisture or mold, throw out that batch immediately and rinse off your container before refilling it with fresh rice. According to The Kitchen, Rice can be stored at room temperature if you eat lots of it; otherwise I recommend refrigerating or freezing individual portions once they’ve cooled completely, of course for easier use.


What About Freezing Leftover White Rice?


You can safely store leftover rice in your refrigerator for up to 4 days. However, if you want to keep it longer than that, freezing is an option as well. If you want to freeze rice, be sure to transfer it into freezer bags or airtight containers first and label it with a write-on sticker.


The same goes for cooked rice. You should never freeze uncooked rice; try making some fried rice instead! For more information on how long foods stay fresh at home, check out our guide: Does Food Go Bad? A Chart Of Shelf Life. Storing Frozen Food.


The Bottom Line About Storing White Rice


If you want to store white rice longer than two months, don’t freeze it. The moisture from frozen rice can cause your cookers to rust and corrode. If you have extra white rice, store it for up to four months in an airtight container at room temperature.


You can also use dry-erase markers on your containers to create a use by date that will help you stay organized as well as save money. Just remember that if white rice gets wet, mold can grow quickly and ruin an entire batch of cooked or uncooked rice! To prevent mold growth, simply make sure all ingredients are thoroughly dried before they go into storage.



Conclusion

The length of time rice can stay in a rice cooker depends on whether you add any moisture to it and how you stored it. If you want to keep your cooked rice for at least two days after cooking, store it without adding any moisture.


For every day that passes, reduce your storage temperature by about 10 degrees Fahrenheit to prevent mold from growing. Store your cooked rice between 40 and 80 degrees Fahrenheit.
