Under USDA household guidance, cooked rice keeps for 3–4 days in the refrigerator at 40°F (4°C) or below, provided it was cooled and refrigerated promptly. This is not a guarantee for rice left warm or on the counter. The same basic window applies to cooked white and brown rice; rice color does not justify a longer storage period.
See the rice entry in USDA storage guidance.
Cool rice promptly
Divide rice into shallow containers and refrigerate as soon as possible. Do not wait for a large pot to cool to room temperature. Refrigerate within 2 hours of cooking, or within 1 hour when the temperature is above 90°F. Cover and date the containers.
Reheat leftovers to 165°F throughout, checking with a food thermometer. Stir during microwave reheating to reduce cold spots. If you will not use the rice within its refrigerator window, freeze it while safely stored. Follow USDA leftover handling guidance.
Do not taste-test questionable rice
Discard rice with mold, an unusual odor or a slimy texture, but do not assume normal-looking rice is safe. Follow the storage history and limits. Never taste food to decide whether it is safe.
