Freezing food, especially meals or leftovers, is economical and time-saving. However, it’s important to use the right container. Glass containers usually aren’t safe for storing frozen food.

Extreme Cold

Good Housekeeping magazine advises against putting glass containers in the freezer. Extreme temperatures may cause the glass to break, wasting a costly container as well as creating a mess in your freezer.


Glass might also break in the freezer because food expands during freezing, so if there is not adequate room in the container, the pressure will break the glass. Liquids expand faster than solids, so never freeze beverages in glass containers.


Instead of glass, Good Housekeeping recommends plastic bags or wrap or heavy-duty aluminum foil. You can also use heavy-duty plastic containers, but also leave at least one inch of empty space above food for expansion, no matter what kind of container you use.

Specialized Glass

According to Evelyn Crayton’s article “The Do’s and Don’ts of Freezing Foods,” some glass jars can be used to store frozen foods, but not to store liquids. Choose wide-mouth jars that are made for freezing and canning, because they are designed to withstand freezing and boiling temperatures.

Other Freezer Tips

For the best flavor and texture, frozen foods should be used within six to nine months. Always store food for freezing in airtight, secure containers and label with contents and date.
