Yes, you can freeze glass jars of jam. In fact, freezing is one of the best ways to preserve your homemade jam. The key is to start with clean, dry jars and to leave enough headspace so that the expansion of the frozen contents doesn’t break the jar.
To do this, simply fill your jars with jam as you would for canning and then screw on the lid. Leave about an inch of space at the top of each jar. Then, set the jars in the freezer and let them freeze solid.
Once they’re frozen, you can stack them if you like. When you’re ready to use a jar of frozen jam, simply remove it from the freezer and thaw it in the refrigerator overnight or at room temperature for a few hours.
How to Freeze in Mason Jars
- Collect all of the supplies that you will need including glass jars, lids, rings, and labels
- Wash your jars and lids in hot soapy water
- Rinse well and then set them upside down on a clean towel to air dry while you make the jam
- Make your jam according to recipe instructions
- Be sure to leave about ½ an inch of headspace at the top of each jar
- Wipe the rims of the jars with a damp paper towel to remove any stickiness or residue
- Place the lid on each jar and screw on the ring until it is finger tight
- Place the jars in a canning pot or large stockpot and fill with enough water to cover the jars by about 1-2 inches
- Bring the water to a boil over high heat and then reduce to a simmer once all of the jars have been added to the pot
- Simmer for 10 minutes to sterilize the jars
- Remove from heat when finished
- Carefully remove each jar from pot using canning tongs
- Drain any excess water off of each one before moving on
- 8 Set aside for 24 hours undisturbed so that they can properly seal
- Check seals after 24 hours by pressing down in center of each lid; if it pops back up then it has not sealed correctly

Can You Freeze Glass Jars of Sauce?
Most people don’t think twice about freezing their tomato sauce in plastic bags or containers, but what about glass jars?
Is it safe to freeze tomato sauce in a glass jar?
Here’s what you need to know. Glass is an excellent material for storing food.
It’s non-porous, so it won’t absorb flavors or odors from other foods. And it’s durable, so it won’t crack or break easily. However, there are a few things to keep in mind when freezing tomato sauce in a glass jar.
First, make sure the jar is made of tempered glass. Tempered glass is stronger than regular glass and less likely to break when exposed to sudden temperature changes (like when you take it out of the freezer). Second, leave some headspace at the top of the jar.
This will allow for expansion as the sauce freezes and prevent the jar from breaking. Finally, don’t tighten the lid too much – just screw it on lightly. Again, this will allow for expansion and prevent the jar from breaking.
If you follow these simple tips, you can safely freeze your tomato sauce in a glass jar!

Can You Put Glass Jam Jars in the Freezer?
Yes, you can put glass jam jars in the freezer. Just make sure to leave some headspace at the top of the jar to allow for expansion. Also, be sure to cool the jam completely before freezing.
What Happens If You Put a Glass Jar in the Freezer?
When you put a glass jar in the freezer, the water inside the jar expands and can cause the glass to crack. The expansion of water is due to the fact that water freezes at a lower temperature than other liquids. For this reason, it is important to not put glass jars in the freezer.
Conclusion
If you’ve ever made your own jam, you know that it doesn’t last forever. But can you extend its shelf life by freezing it in glass jars? The answer is yes!
Freezing jam in glass jars is a great way to keep it fresh for longer. Here’s how to do it:
1. Make sure your jars are clean and dry before adding the jam.
2. Fill the jars to within 1/2 inch of the top with jam.
3. Wipe the rims of the jars clean with a damp cloth.
4. Place a lid on each jar, screwing on the lid tightly.
