What to Know Before Freezing Food

Is freezing food bad?

Absolutely not! As long as it’s done properly, freezing food will lock in nutrients and freshness so your items are just as good as the day they went in the freezer.

Does freezing food kill bacteria?

Not exactly. According to the USDA, freezing food renders bacteria and other microbes inactive, thus preserving your food. Once the food is removed from the freezer and starts to thaw, bacteria and other microbes will become active again and you run the risk of foodborne illness if the items are left out between 40 and 140ºF before being washed and/or cooked. Be sure your freezer temperature reaches 0ºF to freeze food safely.

What’s the best way to freeze food?

This varies a bit by the type of food, but here are some general guidelines on how to freeze food:

Keep things cold: Make sure your freezer is 0°F. Use a refrigerator/freezer thermometer, like this one from LinkDm ($8) for accuracy.
Don’t put hot food in the freezer: If cooked, allow food to cool completely. Placing warm food in the freezer can cause your other foods to thaw.
Wrap and seal food tightly: Foil, plastic wrap and plastic freezer bags help protect food from freezer burn. Try to remove as much air when wrapping to prevent freezer burn. Or if you’re using food storage containers, make sure you’ve left enough space in the container for liquid to expand as it freezes.
Keep food far from the door: Keep foods with a higher risk of foodborne illnesses, like meats, near the back of the freezer, where the temperature is more consistent. Reserve the door, aka the warmest place in your freezer, for items like alcohol or freezer packs.

Plus, follow these tips to prevent freezer burn.

Can you freeze food in Mason jars?

Yes, you can freeze food in Mason jars (or any glass jars) but they require some special care as glass is prone to breaking. Here’s what you need to do to prevent glass containers from cracking in the freezer:

Pick the right jar: Choose a clean, thick-walled glass jar with straight sides. Skip freezing repurposed jars, like pickle or relish jars, and jars with walls that are rounded at the top as the curved design limits the amount of space food has to expand.
Leave headspace: Ensure that you’re leaving enough headspace for food to expand. While some jars have a freeze line etched into them, we suggest to err on the side of caution and leave at least an inch of headspace. If you’re freezing food for the first time, feel free to leave an inch and a half or two to see how much it expands.
Label, label, label: Jot down the contents and the date the food was frozen on the jar. Write this on the lid or keep things organized by using these adorable canning jar labels ($10).

Fridge first: Don’t place glass jars directly in the freezer. Glass can shatter if the temperature changes too much too quickly, Place food in the fridge overnight before transferring to the freezer.

Now that you have some of the basics down, let’s get to freezing some food!
