How Long Does Cooked Rice Last in the Fridge?

Cooked rice should be refrigerated within two hours—within one hour when the air temperature is above 90°F—and used within four days. Store it in shallow covered containers and reheat leftovers to 165°F.

What to know

  • Refrigerate cooked rice within two hours, or one hour above 90°F.
  • Use shallow containers so the rice cools promptly.
  • Use refrigerated cooked rice within four days.
  • Reheat leftovers to 165°F and discard rice with an unsafe time-temperature history.

Put cooked rice in the refrigerator within two hours of cooking, or within one hour when the surrounding temperature is above 90°F. Use refrigerated rice within four days and reheat leftovers to 165°F. Those are the same time-and-temperature limits USDA gives for perishable leftovers generally. [3]

The diagram is a memory aid, but safe storage starts before the rice feels completely cool.

Why cooked rice needs prompt cooling

Uncooked rice can carry spores of Bacillus cereus. Cooking may not eliminate every spore, and organisms can grow when cooked rice sits too long at unsafe temperatures. FoodSafety.gov identifies rice and other starchy foods left too long at room temperature as foods associated with this illness. [2]

This does not mean every pot of room-temperature rice will cause illness. It means time and temperature, not smell alone, control the avoidable risk. Some toxins associated with foodborne bacteria are not reliably fixed by reheating, so “heat it extra” is not a rescue plan for rice left out too long.

Cool and store it safely

  1. Start the clock when cooking ends. Do not wait for the rice to become room temperature.
  2. Transfer leftovers to shallow containers or divide a large batch. USDA recommends shallow containers so leftovers cool rapidly. [3]
  3. Refrigerate within two hours. Use the one-hour limit when the ambient temperature is above 90°F, such as at a hot outdoor meal. FoodSafety.gov states these limits and says refrigerators should be at 40°F or below. [1]
  4. Cover, date, and keep the rice cold. Avoid packing a refrigerator so tightly that cold air cannot circulate.
  5. Use within four days or freeze sooner. If you will not use it in that window, freeze it promptly in a suitable portion.

It is acceptable to refrigerate hot food in small, shallow containers. Leaving a deep pot on the counter until bedtime is the less controlled approach.

Reheating rice

Reheat only the amount you plan to eat. Bring leftovers to 165°F as measured in the food, stirring or rotating so cold spots are exposed. USDA applies the 165°F target to reheated leftovers. [3]

A microwave can heat unevenly. Cover as appropriate, add moisture if the recipe calls for it, stir, and allow standing time before checking more than one spot. Texture can become dry during storage; that is a quality issue and does not change the safety target.

Do not repeatedly warm the whole container and return it to the refrigerator. Each warm cycle adds time and makes the storage history harder to judge.

When to discard rice

Discard cooked rice when:

  • it exceeded the two-hour limit, or one hour above 90°F;
  • you do not know how long it was unrefrigerated;
  • the refrigerator was above 40°F for an uncertain period;
  • it is more than four days old;
  • the container leaked, was contaminated, or has obvious spoilage.

Do not taste it to test safety. Harmful contamination may not produce a warning odor, color, or texture.

For packed lunches, buffets, and takeout, count all time outside temperature control. Keep rice cold at 40°F or below or hot at 140°F or above using equipment designed for that purpose; do not assume an insulated bag or unplugged rice cooker maintains a safe temperature.

Bottom line

Cool cooked rice promptly in shallow containers, refrigerate it within two hours, and use it within four days. Reheat retained leftovers to 165°F. When the time or temperature history is unknown, discard the rice rather than relying on smell, appearance, or another round of heating.

Limits and cautions

  • These are U.S. household food-safety limits for ordinary cooked rice.
  • Smell and appearance cannot prove that improperly stored rice is safe.
  • People at higher risk of foodborne illness may need stricter individualized advice.
