How Long Can You Leave Rice In A Rice Cooker? Surprising Facts

Rice cookers are convenient, simple, and entirely unsupervised while making beautiful, fluffy rice. Many users find the “stay warm” function on rice cookers useful. Additionally, it helps you preserve your rice prepared for the next meal and avoids overcooking. This might be useful for those who have a packed refrigerator or want to make their fridges lighter for safety concerns. Therefore, don’t be shocked if your buddy chooses to store the rice in the rice cooker rather than putting it in the refrigerator or freezer. But how long can you leave rice in a rice cooker?


The quick answer is that rice can stay good in a cooker for up to 12 hours; however, a number of conditions and variables might affect this average.

How Long Can You Leave Rice In A Rice Cooker?

At its “keep warm” settings, the rice cooker may safely be left with cooked rice inside for 11–12 hours. However, keeping the rice in the rice cooker for more than two hours after turning it off poses a risk. At room temperature, cooked rice may support the growth of bacteria, so either leave the cooker plugged in or transfer the rice to an airtight container.


Carelessness about the safety requirements for cooked rice might result in several health risks for you. Eating only half-cooked rice that has gone bad may lead to food illness; thus, caution is required. Every rice cooker has a programmable interface where you may input the necessary temperature and time. You risk experiencing unpleasant side effects, including diarrhea and nausea, if you neglect to remove the cooked rice after it has finished cooking.


However, this does not imply that when the rice cooker’s timer goes off, you must immediately get out of bed and disconnect it. Rice that has been properly cooked may be kept in the rice cooker for 11 to 12 hours without losing flavor or degrading.

Is It Safe to Keep Rice Warm In A Rice Cooker?

Up to 12 hours may be safely spent with rice in a rice cooker on the mode. Following that, microorganisms that are hazardous to your health begin to proliferate in the rice grains. You won’t run into any health concerns if you leave the rice in the rice cooker as long as the temperature is above 140F in a warm setting. But keep in mind that after being heated for a while, cooked rice might become chewy and dry.

How Does The Keep-Warm Function Work?

The keep-warm feature is being added to more versions of rice cookers. It works by keeping the bowl’s inside temperature constant, which is typically 140 or 150 degrees Fahrenheit. The temperature helps preserve the rice ready for serving, stops the grains from draining or burning, and inhibits the formation of microorganisms. Some versions include an extended keep-warm feature that keeps rice warm for up to 12 hours after it has been cooked. But is leaving the rice out for so long safe?

How Do You Keep Rice From Spoiling in a Rice Cooker?

Rice degrades mostly because it contains minute spores, which multiply into bacteria at ambient temperature. To avoid this, rice cookers maintain temperatures far higher than those in which the bacteria may proliferate when cooking and on the keep warm setting. When your cooker is done cooking, switch it to the “keep warm” option and maintain the temperature at or above 60° Celsius (140° Fahrenheit). Maintaining your cooker properly, cleaning it carefully, and ensuring it isn’t damaged or dented can prevent germs from adhering to the surface, further preserving any subsequent batches.

When you serve the rice in the morning, this temperature will guarantee that the grains are secure and warm.

Room temperature storage of cooked rice will promote bacterial development and alter the texture of the grains.


When deciding to keep your rice cooker on overnight, be sure the internal temperature is more than 140F. Otherwise, you risk contracting several illnesses. The flavor of the rice might sometimes be affected by overnight cooking rather than its quality. Being cautious with the heat setting is essential in this situation since your previously well-cooked rice batch may feel crunchy and taste strange after being in the cooker overnight.

Burner Warming

Rice can also be put on the stovetop after being transferred from one bowl to another. Use this approach to ensure the rice bowl has additional moisture and a low burner temperature. Using this technique, you can maintain the color of your cooked rice while keeping it warm and pliable for the party. The finished meal won’t appear as appetizing if you fail to switch off the heat or if the moisture from the cooked rice dries up. It is a good idea to keep the rice pot warm by soaking a cotton towel in water and covering it with it while the burner beneath is set to low.

Get A Caterers’ Hot Holding Cabinet

A holding cabinet is wise if you often throw parties at your home. Due to their built-in tiny burners, caterers utilize these warm holding cabinets and tables to serve hot meals. Get a holding cabinet if running the rice cooker or warming anything on the burner isn’t enough to meet your culinary demands.


Whatever technique you use, make sure the rice is covered and has enough moisture before serving it at the celebration. The final dish will feel crunchy and bland if you reheat rice without leaving any liquid in it.
