Imagine your freezer filled with hearty, nourishing soups and stews ready to be defrosted for a quick lunch on the fly. 

Then imagine a fridge filled with pre-prepped grains, veggies, and proteins, as well as a few mason jar salads ready to throw in your bag on the way out the door.

This scenario is easier than you think; and it all starts with the simple mason jar.

Mason jars are a workhorse in the kitchen, and are the perfect simplified storage solution because they can be used in so many different ways.

They’re durable, are plastic-free, inexpensive, and work perfectly in the pantry, fridge and in the freezer.

As a bonus, the tight sealing lids means you can take soups and stews with you on-the-go without worrying about spills or leaks.

Read on for the step-by-step!

How to Store or Freeze Anything in a Mason Jar

1. Select the Right Jar

For best results, use wide mouth mason jars to freeze one to two portions of soup, stews, or leftovers.

These are my favorite mason jars for freezing one to two servings Wide-Mouth 16-oz Mason Jars

Quart sized mason jars are a great size for storing larger amounts of leftovers, and are also a great choice for pantry organization or creating mason jar salads: Wide-Mouth Quart Mason Jar

2. Allow the Soup, Stew, or Main Dish to Cool

Avoid adding steaming hot liquid to the mason jar. Instead, allow the soup or stew to cool slightly.

3. Transfer to the Mason Jar

Fill each mason jar with the soup, stew, or leftovers using a stainless steel ladle and wide mouth funnel.

The funnel prevents a mess and makes the process so much easier; definitely worth the small investment.

Again, a wide-mouth mason jar is your best best when it comes to freezing anything, especially when it comes to soups and stews.

This is my favorite Wide Mouth Funnel for filling mason jars to freeze.

4. Leave Enough Room

Be sure to leave at least a two inch clearance between the top of the jar and whatever you’re filling it with.

Remember, frozen liquids expand, so don’t overfill, or you will end up with a cracked jar.

5. Cool Completely in the Refrigerator

Screw on the lids and refrigerate the filled jars and allow to cool completely to avoid cracking.

6. Add a Label

Don’t forget to label your jars.

Particularly if you plan to store in the freezer, clear labeling will ensure you know what’s what.

Labeling couldn’t be easier: simply write the name of the item along with the date on a small piece of washi masking tape with a permanent marker.

Then affix the tape to the top of the lid and you’re good to go.

When you’ve used the contents of the jar remove the tape and wash the lid. 

7. Freeze the Mason Jars

Freeze contents for three to five months.

8. Bonus Tip: Everything in its Place

Store mason jar lids in a wire basket when not in use to keep things organized.

    Wire basket to wrangle the lids, Yes! This is what I needed.

    • Robyn Downs

      Stacy, right?! It’s the simple things. Those lids were always driving me crazy and just designating a spot for them has made such a difference! 🙂

  • Ashley

    I store our mason lids in a cardboard box. It isn’t pretty, but it was free! And it’s stashed away in the cupboard anyway so you never see it.

  • Laura

    I keep finding my lids get rust easily. Am I doing something wrong or how do I avoid this?

    • Niki

      I use little pieces of wax paper under the lid (you can keep them square or even cut them into a circle with pinking shears to make them look pretty). I found that it creates a tighter seal, and the lids stay clean (no extra washing).

  • Caroline

    What’s the best way to reheat the soup or a single portion of something I have frozen in a mason jar?

    • Robyn Downs

      A couple options, Caroline. First, you can use a microwave on defrost, then dump into a bowl and heat. If you’re rather not use a microwave, put the frozen jar in the fridge overnight, it should thaw within a day, or place in a jar of lukewarm water. Then reheat on the stove top!

  • Maria

    I found plastic lids to use on my wide mouth jars! These seem much easier to deal with then the rings. Come to find out they make a ton of attachments for mason jars, like honey sticks, coffee lids, spice lids..etc. 🙂 Im in Mason Jar Heaven! Thanks for the post!

  • Ashley Moo

    Can I store raw meat in Mason jars in my freezer?

    • Robyn Downs

      Ashley, yes, just as you’d use any freezable container, if you have raw meat it should work to freeze–keep in mind you’ll need to leave room at the top, as things expand when they freeze–to avoid cracked jars.
