Canning jars are the best way I know to avoid using plastic when freezing foods. You’ll want to use wide mouthed canning jars like the one above, that come in pint and half pint sizes. Don’t use jars with shoulders–these jars will break due to the expansion that happens when food is frozen.

Kerr and Ball jars are marked with a freeze fill line that’s about an inch below the rim. Don’t put food you intend to freeze above this line.

Avoiding plastic lids is more difficult. Two piece Ball lids have a BPA coating (which, I’ve heard that they are considering phasing out). I suppose you could use a BPA-free Tattler lid, though I haven’t tried them. For freezing I use food grade plastic lids sold by Ball. Food is not in contact with the lid, so I’m not too concerned about the plastic, though I understand that some people won’t agree. At least the lids are more easily reused than ziplock bags. It looks like Ball now has BPA free lids.

But jars won’t work for freezing a pork chop–see an interesting thread on Chowhound about this issue that Root Simple reader Peter Shirley alerted me to. Long story short: home freezing is a product of the post WWII era of plastics and refrigeration, so there’s not a lot of alternatives other than the jar option and less than optimal aluminum foil and heavy paper. It’s hard to beat the moisture retaining and freezer burn excluding properties of plastics. The plastic-free meat freezing alternative is to bring back the corner butcher shop and buy fresh.

A good question came in on Friday’s post about freezing fruits and vegetables about how to freeze meat products without using plastic bags. I don’t know of a way to avoid plastic with meat products, but you can use freezer paper instead of ziplock bags. The University of Georgia Extension Service has a handy info sheet on how to wrap meat with freezer paper: Freezing Animal Products.

Correction: an earlier version of this post was entitled “How to Freeze Meat Without Using Plastic.” I had forgotten that freezer paper is coated with plastic. You can use glass canning jars to freeze (just don’t use a jar with a shoulder). While jars are a great way to freeze soups and stews, they are not suitable for cuts of meat. If you are aware of a way to freeze cuts of meat without plastic, please leave a comment.
