If you ask, “Can Mason Jars be frozen without breaking?” then it’s a big yes! There are tips and ways to prevent it from breaking, so you must follow them.

Always Leave a Headroom

When you freeze a portion of food, it generally expands, and the only area it can go to is the space or headroom you leave at the top.

To keep your mason jar from shattering in the fridge, you must leave plenty of space at the top.  

The universal rule of thumb is one inch of headroom: the larger your mason jar, the plenty of space to fill it in. The more food you freeze, the more chances of it expanding.

Thus, you’ll have to leave more headspace to avoid your material from breaking.  

Cool Your Food or Ingredient

If there is one guaranteed way to break your mason jar in your fridge, it’s a thermal shock.

When the rise in temperatures is incredibly tremendous and ultimately too much for your container to take, thermal shock occurs.

A great example would be placing a piping hot carbonara sauce into your container and then tossing it right into the freezer, 

Cooling your food or ingredient for 5-10 mins before placing it in the container as slowly as you can is the safest and best method to prevent thermal shock and stop your mason jar from shattering in the freezer.

Don’t Place It Near Cooling Elements

Stop placing them next to, on top of or besides, the cooling component of the fridge to keep your container from cracking in the freezer.

  • Chest Freezer – The cooling element can be found in the very bottom
  • Upright Freezer – The cooling element may be found at the very back

If you position it in an upright freezer door, or close to the top, or in a chest freezer basket, your jar will still freeze and be cool enough.

And the risks of destroying the pot will go down!

Protect Your Mason Jars

As states above, jars contract and expand while they are in the freezer, just like the container’s contents.

It might not sound like a big deal but stuffing the jars in your fridge right next to one another leaves no wiggle space for the container to move.

Placing the jars near each other may cause them to wobble or rattle any time you open the fridge’s door.

The speed at which the glass freeze will change if they are kept too close together. Note, you wouldn’t want to freeze them too soon.

Before placing your glass in the refrigerator, put them inside a shatter-proof plastic container or a cardboard box to prevent them from getting knocked up by one another.
