How to freeze food safely
Freeze food safely by cooling it quickly in shallow containers, packing it airtight with the air pressed out, labeling it with the name and date, and keeping the freezer at 0 degrees Fahrenheit. Frozen food stays safe indefinitely at that temperature, but quality fades, so aim to eat most cooked meals within two to three months. Thaw in the fridge, not on the counter.
Why it matters: Knowing what freezes and how long it keeps turns leftovers into future meals.
Steps
- Cool cooked food within two hours, dividing large amounts into shallow containers.
- Pack into freezer bags or airtight containers, pressing out the air.
- Freeze bags flat so they stack and thaw evenly.
- Label each with what it is and the date.
- Keep the freezer at 0 degrees Fahrenheit and check it with a thermometer.
- Thaw in the fridge overnight, or in cold water in a sealed bag changed every half hour.
- Cook food thawed in cold water right away; fridge thawed food keeps a day or two, and reheat cooked food to 165.
Stop and call a professional if
- the power has been out and the freezer is warm: food above 40 degrees for more than two hours should be thrown out; when in doubt, throw it out
- someone gets sick after eating, with fever, blood in the stool or signs of dehydration: contact a clinician
Common mistakes
- Thawing meat on the counter.
- Freezing food that has already sat out for hours.
- Skipping labels and finding mystery boxes months later.
