Leftover cooked stuffing may be frozen for up to one month for safe use. To ensure the freshest stuffing, freeze the mixture in an airtight, sealed container or freezer bag.
Stuffing should be frozen within two hours of preparation. Discard fresh or frozen stuffing with discoloration or an unnatural odor.
Cool stuffing prior to refrigeration. Cooked stuffing can be refrigerated for up to three or four days prior to use. Stuffing should be reheated to 165 degrees Fahrenheit for safe consumption. Stuffing left at room temperature for more than two hours is unsafe to eat due to bacterial contamination. For optimal flavor, uncooked stuffing should not be refrigerated.
