- open the can and transfer the product to a freezer-safe container or bag. Do not freeze food in the can.
- drain products that are packed in water, juice, or oil before freezing. This liquid can be frozen and saved, too, of you think you'll have use for it later. However, there are exceptions to the draining rule. I find that our family likes the texture of canned tomatoes frozen in their juice.
- canned meals, such as soups, stews, and pasta dishes in sauce, are best kept in their liquids.
- mark frozen meat products with a clear expiration date.
- do this BEFORE the printed expiration date on the can.
- for the most part, the suggested time limit for freezing concerns best quality and not safety.
canned meat, such as tuna, chicken, ham before expiration date, open can, drain, place in freezer bag, squeeze out excess air and freeze for up to 3 months. Best practice -- use a Sharpie to write "expiration date: XX/XX/XXXX (date that is 3 months into the future from point of freezing)."
canned vegetables according to eatbydate.com, unopened canned vegetables, when properly stored, can safely be consumed up to 1 to 2 years beyond the expiration date printed on the can. However, if you'd like to freeze the canned veggies, open can, drain, place in freezer bag, squeeze out excess air, and freeze for up to 2 months.
canned olives canned olives freeze quite well. Simply drain, pat dry with a paper towels, pack in freezer bag, squeeze out excess air, and freeze for up to 6 months.
canned fruit drain the juice and pour into a freezer-safe container and freeze, Place drained fruit in freezer bag, squeeze out excess air, freeze for up to 2 months. The juice and fruit can be thawed and recombined or the juice can be used separately for another purpose. (We like to save canned pineapple juice to add to a pitcher of orange juice or use in marinades.)
canned fruit sauces, such as applesauce transfer to an airtight container and freeze for up to 2 months.
canned milk canned milk can be frozen, but the consistency will change somewhat when frozen. Milk solids tend to separate from the liquids in freezing. And for some, this makes the thawed product less appealing. However, frozen/thawed canned milk still works great in cooking, such as for making soups and sauces, baking, etc. Best practice -- for canned evaporated milk, open the can and pour into ice cube trays. Freeze solid then transfer the frozen milk cubes to a freezer bag. Freezing milk in small portions makes it easy to grab just how much you need for a particular recipe without thawing too much.
For sweetened condensed milk, freeze in small containers or freezer bags and not in ice cube trays. The high sugar content in sweetened condensed milk prevents the cubes from freezing solid.
Both types of canned milk will keep, frozen, for up to 3 months.
canned pasta meals, soups, and stews empty contents of cans into freezer bags or airtight freezer containers. Freeze and use within 2 months, for best quality.
jarred or canned sauces for tomato-based pasta sauce, transfer to a freezer-safe container and freeze up to 3 months.
Gravy and other opaque/thickened sauces tend to separate when frozen. However, it can be frozen and remedied once thawed. Transfer contents of can or jar to a freezer container and freeze for up to 3 months. Once thawed, reheat and whisk vigorously, adding some liquid as needed.
Canned jellied cranberry sauce separates and becomes watery once frozen and thawed. It is still safe but you may need to heat it to melting, then cool to recombine. To freeze, transfer to freezer container and keep frozen up to 3 months.
For myself . . . A couple of times per year, I check expiration dates on my canned foods. When I find something nearing its expiry, I make a choice to use it right away or go ahead and freeze the contents. It's surprising how suddenly a bunch of cans of pumpkin about to expire can sneak up on me.
In addition, I frequently find myself with a half-can of something leftover, which I will freeze to use another time.
