Kerr mason jars are a popular choice for canning and preserving food, but can they also be used for freezing? Many people wonder if these jars are freezer safe, and if so, what precautions should be taken to ensure that they don’t crack or break.
The good news is that Kerr mason jars are indeed freezer safe. These jars are made from high-quality glass that is designed to withstand extreme temperatures, including freezing. However, there are a few important factors to keep in mind to ensure the jars are used properly in the freezer.
Firstly, it’s important to leave enough headspace in the jar when filling it with food for freezing. Liquids, in particular, expand when they freeze, so it’s necessary to allow room for this expansion to prevent the jar from cracking. Generally, it is recommended to leave about 1 inch (2.5 cm) of headspace at the top of the jar.
Secondly, it’s important to use proper lids and seals for freezing. The typical metal lid and screw band that are used for canning may not be sufficient for freezing. Instead, it is recommended to use plastic freezer-proof lids that are specifically designed for freezing. These lids provide a tight seal and are less likely to break or crack in the freezer.
Lastly, it’s important to handle the jars with care when taking them out of the freezer. Glass can become brittle when exposed to extreme temperatures, so it’s advisable to let the jar thaw gradually in the refrigerator or in a bowl of cold water rather than subjecting it to sudden temperature changes. This will help to minimize the risk of cracking or breaking.
So, if you have some Kerr mason jars and are wondering if they can be used for freezing, the answer is yes. Just remember to leave enough headspace, use proper freezer-proof lids, and handle the jars with care when taking them out of the freezer. With these precautions, you can safely freeze your favorite foods in Kerr mason jars and enjoy them later.

Can You Freeze Food in Kerr Mason Jars?
Kerr Mason jars are a popular choice for canning and preserving food, but can you use them for freezing food as well? The answer is yes, but with some precautions.
When it comes to freezing food in Kerr Mason jars, it’s important to remember that the glass can become very brittle when exposed to extreme temperatures. To prevent the jars from cracking or breaking, you should take a few steps before placing them in the freezer.
Choose the Right Jar Size
It’s crucial to select the appropriate size of Kerr Mason jar for freezing food. Using wide-mouth pint or quart jars is recommended because they allow for expansion during freezing. Avoid using jars with narrow necks as they may crack more easily.
Leave Headroom for Expansion
When filling Kerr Mason jars with food for freezing, you should leave some headspace to allow for expansion. The general rule of thumb is to leave about an inch of space at the top of the jar. This extra space will accommodate any expansion that occurs during the freezing process.

How to Prepare Kerr Mason Jars for Freezing
If you’re wondering whether Kerr Mason jars are safe to use in the freezer, the answer is yes. However, there are a few guidelines you need to follow to ensure the jars don’t crack or break during the freezing process.
Cleaning the Jars
Before using Kerr Mason jars for freezing, it’s important to properly clean them. Start by washing the jars and lids in warm, soapy water. Rinse them thoroughly to remove any soap residue. You can also run them through a dishwasher cycle to ensure they are sterilized.
Note: It’s recommended to use new lids or at least lids that are in good condition to ensure a tight seal and prevent any freezer burn.
Choosing the Right Jar Size
When freezing with Kerr Mason jars, it’s important to choose the right size. The larger the jar, the more risk there is for breakage due to expansion. It’s best to use pint-sized or smaller jars for freezing.
Leaving Head Space

Tips for Freezing in Kerr Mason Jars
Using Kerr Mason jars for freezing can be a convenient way to store and preserve your food. However, there are a few important tips to keep in mind to ensure the safety and effectiveness of freezing in these jars.
Choose the Right Size Jar
When freezing in Kerr Mason jars, it is important to choose the right size jar for your food items. The size of the jar should accommodate the volume of the food, leaving enough headspace for expansion during freezing.
For liquids such as soups or sauces, it is recommended to leave about 1 inch of headspace to allow the food to expand as it freezes. For solid food items, you can leave about half an inch of headspace.
Use Wide-Mouth Jars
Wide-mouth Kerr Mason jars are ideal for freezing as they allow for easy filling and pouring of your food items. The wider opening also helps in preventing any breakage or cracking of the jars during freezing and thawing.
Using regular-mouth jars can be more challenging as it may be difficult to fill them without spilling or touching the sides of the jars, which can lead to breakage. So, opt for wide-mouth jars whenever possible.
Label and Date the Jars
Labeling and dating the Kerr Mason jars before freezing is essential to keep track of the contents and the storage duration. Use a waterproof pen or marker to write the name of the food and the date of freezing on the lid or the glass itself.
Proper labeling will help you identify and rotate your frozen items, ensuring that you use the oldest ones first and preventing any waste due to food spoilage.
Leave Room for Expansion
Freezing causes liquids to expand, so it is important to leave some room for this expansion in the jars. Filling the jars completely can lead to breakage, as the expanding food will have nowhere to go.
For liquids, about 3/4 of the jar’s capacity should be filled to allow space for expansion. For solid food items, the food should be packed loosely to accommodate expansion.
Note: Be cautious when reusing Kerr Mason jars after freezing as the glass may become more prone to breaking or cracking. It is recommended to inspect the jars for any visible signs of damage or stress before reusing them.
In conclusion, Kerr Mason jars can be safely used for freezing with proper care and attention. By following these tips, you can ensure the best results and enjoy the convenience of using these versatile jars for your frozen food storage needs.
