If you’re looking for an easy way to save money and time, freezing your own spaghetti sauce in glass jars is a great option. It’s simple to do and the sauce will last for months in the freezer. Plus, you’ll always have homemade sauce on hand when you need it.
Here’s how to freeze glass jars of spaghetti sauce.
- Start with clean, dry jars
- If you’re using new jars, sterilize them by boiling for 10 minutes
- Fill the jars with sauce, leaving about ½ inch of headspace at the top of each jar
- Wipe the rims of the jars with a damp paper towel or clean cloth to remove any sauce that might be clinging there
- This will help create a good seal when you screw on the lid
- Place a lid on each jar, screwing on the band until it’s fingertip-tight
- submerge the filled and sealed jars in a large pot or canner of boiling water, making sure they’re covered by at least an inch of water
- 6 Boil for 25 minutes to process (this time will vary depending on your altitude—see this chart for specifics)
- 7 Carefully remove the jars from the canner and set them on a folded towel to cool; do not retighten their lids

Are Glass Jars Freezer Safe?
You might be surprised to learn that glass jars are actually freezer safe. That’s right, you can place them in the freezer without fear of them breaking. However, there are a few things you need to keep in mind in order to ensure that your jars don’t break or crack.
First, it’s important to use jars that are made specifically for freezing. Canning jars are a good option, but make sure they are labeled “freezer safe.” Second, make sure the jars are clean and dry before placing them in the freezer.
Any moisture on the jar can cause it to crack when exposed to the cold temperatures.
Once your jars are prepped and ready to go, fill them with whatever you’d like to freeze (soups, sauces, etc.) and then screw on the lid tightly. Place the jars in the back of the freezer where it is coldest and allow them to freeze for several hours or overnight.
When you’re ready to use one of your frozen jars, simply remove it from the freezer and thaw it out in the fridge or at room temperature. Be careful when opening thawed jars as contents may be hot or under pressure due to expansion during freezing.
