Can You Freeze Canned Mushrooms?
Canned mushrooms are handy to keep in the cupboard because they last for ages and are ready to use straight from the tin (can).
But once you’ve opened them, you might be wondering whether you can freeze canned mushrooms rather than letting the rest go to waste.
The good news is that you can.
Whether you’ve only needed a handful for a pizza, stir fry or pasta sauce, freezing the leftovers is an easy way to save both food and money.
Can You Freeze Canned Mushrooms?
Yes, you can freeze canned mushrooms.
Canned mushrooms are already cooked, so they freeze well and can be stored in the freezer for around 3 months. Once thawed, they’ll usually be a little softer than before freezing, so they’re best used in cooked dishes rather than served on their own.
Can You Freeze Canned Mushrooms After Opening?
Yes.
Once you’ve opened a tin (can), transfer any leftover mushrooms to a freezer-safe container and freeze them as soon as possible.
If you think you’ll use them within 3-4 days, you can simply keep them in the fridge instead.
Never store leftover mushrooms in the opened tin. Once opened, the mushrooms should always be transferred to another container before refrigerating or freezing.
Can You Freeze Leftover Canned Mushrooms?
Absolutely.
Whether you’ve accidentally opened a tin or only needed a few mushrooms for a recipe, freezing the leftovers is much better than throwing them away.
I usually give them a quick rinse to remove most of the brine before freezing, then let them drain well. It isn’t essential, but I find it gives a better result after thawing.
How To Freeze Canned Mushrooms
Freezing canned mushrooms is simple.
- Drain the mushrooms and, if you like, rinse away most of the brine.
- Pat them dry with kitchen paper.
- Transfer them to a freezer-safe container or freezer bag.
- Freeze in portions you’ll actually use.
- Label and date before placing them in the freezer.
Top tip: If you regularly use small amounts, freeze them in recipe-sized portions. It saves having to defrost more than you need.
How Long Do Canned Mushrooms Last In The Freezer?
Canned mushrooms are best used within 3 months.
After that they’ll still be safe to eat if they’ve remained frozen, but the texture becomes progressively softer and they may lose some flavour.
How To Defrost Canned Mushrooms
The safest way to thaw canned mushrooms is overnight in the fridge.
If you’re adding them to soups, casseroles, pasta sauces or stews, there’s often no need to defrost them first. Simply stir them into the dish straight from frozen.
How To Reheat Canned Mushrooms
Once thawed, reheat the mushrooms as you normally would.
You can:
- warm them in a frying pan
- microwave them
- add them directly to hot sauces, casseroles or stroganoff
If reheating on their own, make sure they’re piping hot before serving.
Frequently Asked Questions
Can I freeze canned mushrooms?
Yes. Canned mushrooms freeze well for around three months and are a great way to prevent food waste.
Should you rinse canned mushrooms before freezing?
It’s optional, but I usually do. Rinsing off most of the brine and allowing the mushrooms to drain helps prevent excess liquid and ice crystals during freezing.
Can you freeze sautéed canned mushrooms?
Yes. If you’ve cooked the canned mushrooms first, allow them to cool completely before freezing. They can then be frozen in exactly the same way.
