Canning jars are a great way to store food for later use. However, you may be wondering if you can freeze in canning jars. The answer is yes!
Freezing in canning jars is a great way to preserve your food. Here are some tips for freezing in canning jars:
-Choose the right size jar.
Canning jars come in a variety of sizes, so make sure to choose one that will fit the amount of food you want to freeze.
-Fill the jar with food, leaving about an inch of headspace at the top of the jar.
-Wipe the rim of the jar with a clean cloth or paper towel to remove any residue.
-Place a lid on the jar and screw on the band until it is tight.
-Label the jar with the date and contents.
-Place the jar in the freezer and allow it to freeze for several hours or overnight.
- Wash your canning jars in hot, soapy water
- Rinse well and set aside to air dry
- Place your food item in the canning jar, leaving about an inch of headspace at the top of the jar
- Use a funnel to pour your chosen freezing liquid into the jar, filling it to within ½ inch of the top of the jar
- Remove any air bubbles by gently tapping the side of the jar with a spoon or butter knife
- Add more liquid if necessary to maintain the ½-inch headspace
- Clean the rim of the jar with a damp paper towel or cloth and place a lid on top, screwing on the band until it is “fingertip tight” (tightened until you can still twist it with your fingers)
- Label your jars with contents and date before placing them in your freezer
How to Freeze in Mason Jars
Can You Freeze in Regular Canning Jars?
Yes, you can freeze in regular canning jars. Be sure to leave headspace (the amount of space between the food and the top of the jar), as contents will expand when frozen. Headspace is typically 1-2 inches.
To prevent jars from breaking, place a layer of newspapers or towels at the bottom of a box or container before adding jars. Regular mouth canning jars with lids and screw bands can be used for freezing. Fill jars with food, leaving recommended headspace for each type of food (refer to chart below).
Wipe rims clean; apply two-piece lids. Let air escape from hot foods by placing a wooden spoon in the jar; remove before sealing. Label and date your creation.
Regular Mouth Pint Jars: ½ – 1 inch headspace
How Do You Know If Mason Jars are Freezer Safe?
Mason jars are a type of canning jar that has a wide mouth and screw-on lid. They are made of glass and come in various sizes. Mason jars are popular for canning and preserving food, but they can also be used for storing food in the freezer.
To know if a mason jar is freezer safe, look for the letter “F” on the bottom of the jar. This letter indicates that the jar has been tested and approved by the United States Department of Agriculture (USDA) for freezing. If you see an “F” on a mason jar, it means that it is safe to use for freezing food.
Another way to tell if a mason jar is freezer safe is to check the manufacturer’s website or product label. Some manufacturers will specifically say that their jars are safe for freezing, while others may not mention it at all. However, if you don’t see any mention of freezing on the product label or website, it’s best to assume that the mason jar is not meant to be used for freezing food.
In general, it’s best to err on the side of caution when freeze foods in mason jars. If you’re unsure whether or not a particular mason jar is freezer safe, it’s best to either contact the manufacturer or simply choose another container for your frozen food storage needs.
Do Mason Jars Break in the Freezer?
Mason jars are a popular choice for canning and storing food, but they can also be used for freezing food. While mason jars are designed to withstand high temperatures, they can break if exposed to extreme cold. This is because the glass of a mason jar is susceptible to thermal shock, which means it can crack or shatter if it goes from hot to cold too quickly.
If you’re planning on freezing food in a mason jar, it’s important to take some precautions to prevent the jar from breaking.
Before freezing any food in a mason jar, make sure that the jar is clean and dry. Any moisture on the inside or outside of the jar can cause it to break when frozen.
Fill the jar with your desired food item, leaving about an inch of headspace at the top of the jar. Be careful not to overfill the jars as this can also cause them to break. Once filled, screw on the lid tightly and place the jars in the freezer.
If you’re worried about your jars breaking in the freezer, you can wrap them in towels or newspaper before placing them in freezer bags or storage containers. This will help cushion them and keep them from moving around too much, which could lead to cracking or shattering. Mason jars that are properly cared for and stored should last for many years without breaking – even when frozen!
How Do You Freeze Things in Glass Jars?
When it comes to freezing things in glass jars, there are a few things you need to keep in mind. First of all, make sure that the jars you are using are made for freezer storage. You don’t want to use regular canning jars, as they are not designed to withstand the extreme cold temperatures of a freezer.
Second, make sure your jars are clean and dry before adding any food or liquid to them. Third, leave some headspace in the jar so that the contents have room to expand as they freeze. And finally, don’t forget to label your jars with what’s inside and the date it was frozen!
Now that you know the basics, let’s get into how to actually freeze things in glass jars. One of the most important things to remember is to not fill the jar all the way up – leave about an inch or two of space at the top. This headspace is crucial because it allows for expansion as the contents freeze.
Otherwise, your jar could crack or break from the pressure.
Once you’ve left enough headspace, go ahead and add whatever you’re wanting to freeze into the jar. Soups, sauces, stews, and even baby food can be frozen in glass jars (just be sure to leave extra headspace for baby food since it expands more than other foods).
Once your jar is full, screw on the lid tight and place it in your freezer upright. And that’s it!
Just remember that when you’re ready to use something that was frozen in a glass jar, thaw it out slowly by either letting it sit out on counter overnight or submerging it in cold water until thawed (never use hot water!).
And always check your jars before using them – if there are any cracks or chips present, do not use that jar as its contents may no longer be safe to eat.

Can I Freeze Mason Jars With Metal Lids
Mason jars are a popular choice for freezing food because they are durable, easy to use, and come in a variety of sizes. But can you freeze mason jars with metal lids?
The answer is yes!
You can freeze mason jars with metal lids, but there are a few things to keep in mind. First, make sure the lid is screwed on tight so that no air can get in and cause the food to freezer burn. Second, if you plan on stacking the jars, place them upside down so that the weight of the other jars doesn’t crush the contents.
Here are some tips for freezing different types of foods in mason jars:
-Soups and stews: Ladle into jar, leaving 1-2 inches of headspace at top. Screw lid on tightly and freeze.
To reheat, thaw overnight in fridge then heat on stovetop over low heat until warmed through.
-Fruits and vegetables: Wash and chop fruits or veggies then blanch (if desired). Place in jar, screw lid on tight, and freeze.
When ready to eat, thaw overnight in fridge then use as you would fresh fruit or veggies.
-Meat: Cook meat then place in jar, leaving 1-2 inches of headspace at top.
Can You Freeze Glass Jars of Jam
If you’ve ever made your own jam, you know that it can be a bit of a process. First, you have to sterilize the jars, then cook the fruit down into a thick syrup, and finally carefully ladle the hot jam into the jars. All that work only to find out that your jam has gone bad after just a few weeks in the pantry?
It’s enough to make you want to give up on homemade jam altogether. But what if we told you there was a way to make your jam last longer – much longer?
Yes, it is possible to freeze glass jars of jam!
This simple technique will extend the shelf life of your jam by months, so you can enjoy those summertime flavors all year round. And best of all, it doesn’t require any special equipment or ingredients – just your usual jar of jam and some space in the freezer.
Here’s how it works: simply pour your freshly-made (and still warm) jam into a clean glass jar, leaving about ½ inch of headspace at the top.
Then screw on the lid and place the jar in the freezer. That’s it! As long as you use a good quality sealable jar, yourjam will be perfectly safe in the freezer for up to 12 months.
When you’re ready to enjoy some frozen jams , simply thaw them overnight in the fridge or place them in a bowl of warm water for about an hour. Once thawed, give them a good stir before serving – they may be slightly thicker than when first made but will still taste delicious!
Can You Freeze Fruit in Mason Jars
You can freeze fruit in Mason jars, but there are a few things to keep in mind. First, make sure to leave enough headspace at the top of the jar for the fruit to expand as it freezes. Second, use a wide-mouth jar so that it’s easy to get the frozen fruit out.
Third, consider using a silicone sleeve or wrapping the jar in a towel to prevent it from breaking when it expands. Finally, remember that frozen fruit will last for several months in the freezer.
Can You Freeze Glass Jars of Spaghetti Sauce
Most people don’t realize that you can freeze glass jars of spaghetti sauce. Yes, it’s true! You can extend the shelf life of your sauce by freezing it in glass jars.
Here’s how to do it:
1. Choose jars that are specifically designed for freezing. These will have thicker walls and a special coating that prevents them from breaking when exposed to extreme cold temperatures.
2. Fill the jars with sauce, leaving about ½ inch of headspace at the top to allow for expansion during freezing.
3. Wipe the rims of the jars clean and screw on the lids tightly. Be sure to label each jar with the date so you know how long it’s been in the freezer.
4. Place the jars in the coldest part of your freezer and allow them to freeze for up to six months.
Can You Freeze Mason Jars With Soup
If you’re anything like me, you love soup. It’s hearty, filling, and warms you up on a cold day. But sometimes, life gets in the way and you don’t have time to finish a whole pot of soup.
If this happens to you, don’t worry! You can freeze your soup in Mason jars and enjoy it at a later time.
Here’s how to do it:
1. Make sure your Mason jars are clean and dry before adding any soup to them. I like to sterilize my jars in boiling water for about 10 minutes just to be safe.
2. Once your jars are sterilized, let them cool before adding soup.
Hot soup can cause the glass to crack so it’s important to let the jars cool completely before proceeding.
3. When adding soup to the jars, leave about an inch of space at the top of each jar. This will give the soup room to expand as it freezes and prevents the jar from cracking or breaking.
Can You Freeze Vegetables in Mason Jars
Assuming you’re talking about freezing vegetables in Mason jars:
Can You Freeze Vegetables in Mason Jars?
The quick answer is yes, but there are a few things to keep in mind.
First of all, it’s important to use wide mouth jars so that the vegetables have enough room to expand as they freeze. Make sure to leave about an inch or two of headspace at the top of the jar. It’s also important to blanch your vegetables before freezing them; this will help preserve their color, texture, and flavor.
Finally, make sure to use a water-tight lid; freezer-safe canning lids are ideal.
Here’s a step-by-step guide to freezing vegetables in Mason jars:
1. Start by boiling some water and prepping your workstation.
Fill a large pot with water and set it on the stovetop to boil. Meanwhile, gather your clean and dry Mason jars, lids, and rings. Place the jars on a baking sheet lined with a towel or parchment paper.
Have a second towel or piece of parchment paper ready for placing over the filled jars (this will come in handy later).
2. Blanch your veggies. Once the water is boiling, add your veggies and let them cook for 2-3 minutes (depending on their size/type).
Use a slotted spoon or spider strainer to transfer them from the pot of boiling water into a bowl of ice water (this will stop the cooking process). Let them sit in the ice bath for another 2-3 minutes before draining them well.
3. Fill your jars with blanched veggies leaving 1-2 inches of headspace at the top of each jar.
* Be sure to pack them tightly so that there aren’t any air pockets (which could cause freezer burn). Wipe any moisture off of the rims of the jars using a clean towel or paper towel.*
4a) If using regular canning lids: Put fresh canning lids on each jar finger tight and then process in a boiling water bath for 10 minutes.* Remove from heat and allow jars to cool undisturbed on counter until completely cooled – do not tighten rings further once removed from heat! After 12 hours check seals – if unsealed refrigerate and use within 2 weeks OR reprocess within 24 hours using same processing time.
Can You Freeze Mason Jars With Plastic Lids
You can freeze mason jars with plastic lids, but there are a few things to keep in mind. First, make sure the lid is tight-fitting and that there is no air space between the lid and the jar. Second, place the jars on a baking sheet or other flat surface in the freezer so they don’t tip over.
And finally, allow plenty of time for the jars to thaw before opening them; otherwise, the contents may explode.
Conclusion
Yes, you can freeze in canning jars, but there are a few things to keep in mind. First of all, make sure the jars are clean and dry before adding any food. Secondly, leave about an inch of headspace at the top of the jar to allow for expansion during freezing.
Lastly, be sure to use a regular lid (not a screw-on type) and tighten it only until finger-tight.
