How to Store Cooked Rice?
Cool cooked rice quickly. This can be done by spreading it out and, once cool, storing it in an airtight container or in a freezer bag with the air removed.
You should aim to refrigerate your rice within two hours. Refrigeration slows down the growth of nasty bacteria. According to the USDA, room temperature is 90°F, which is the ideal temperature for bacteria to grow. Bacteria grow rapidly between 40°F and 140°F so make sure your fridge is at 40°F or lower.
Freeze any excess rice if you want it to last longer than a few days.
How to Test Cooked Rice
If you're not sure how long your rice has been in the fridge, check its condition. If it has an unpleasant smell, gooey texture, or mould it is no longer safe to eat. If in doubt, throw it out.
