Can You Freeze Stuffed Mushrooms?
Do you want to know if you can freeze stuffed mushrooms? This post covers everything you need to know about freezing stuffed mushrooms before and after they have been cooked.
Stuffed mushrooms are a popular choice as a starter, appetiser or light lunch.
They’re also a brilliant way to use up odds and ends lurking at the back of the fridge, whether that’s leftover cheese, herbs, breadcrumbs or even a little cooked bacon.
If you’ve made too many, freezing them is a great way to prevent food waste and means you’ve got an easy starter or light meal ready for another day.
Can You Freeze Stuffed Mushrooms?
Yes, stuffed mushrooms can be frozen. You can freeze both cooked and uncooked stuffed mushrooms, although freezing them before cooking generally gives the best results.
If you’re freezing stuffed mushrooms that have already been cooked, don’t worry – they’ll still taste great. The mushrooms may just be a little softer once they’ve been thawed and reheated.
Can You Freeze Uncooked Stuffed Mushrooms?
Yes, you can freeze uncooked stuffed mushrooms. In fact, this is the best time to freeze them if possible.
Because the mushrooms haven’t been cooked yet, they hold their texture much better once baked. This makes stuffed mushrooms an ideal make-ahead dish for Christmas, dinner parties or busy weeknight meals.
Simply prepare them as normal, freeze them, then cook them whenever you need them.
Can You Freeze Cooked Stuffed Mushrooms?
Yes, cooked stuffed mushrooms freeze well too.
Allow them to cool completely before freezing, then transfer them to an airtight freezer-safe container or freezer bag.
When reheated, the mushroom itself may be slightly softer than when freshly cooked, but they’ll still be perfectly safe to eat and just as tasty.
How Long Do Stuffed Mushrooms Last In The Fridge?
If you’re planning to serve your stuffed mushrooms within a day, you probably won’t need to freeze them at all.
Homemade stuffed mushrooms will usually keep for around 24 hours in the fridge before cooking. Keep them covered until you’re ready to bake them.
If they’re already cooked, store any leftovers in the fridge and eat them within two days, or freeze them instead.

How To Freeze Stuffed Mushrooms
Freezing stuffed mushrooms is straightforward.
- If you’re freezing cooked stuffed mushrooms, allow them to cool completely first.
- Arrange them in a freezer-safe container. If possible, keep them in a single layer so they don’t stick together as they freeze.
- If you’re freezing lots of mushrooms, you can flash freeze them on a baking tray first before transferring them to a freezer bag or container.
- Label and date the container before placing it into the freezer.
How Long Do Stuffed Mushrooms Last In The Freezer?
Stuffed mushrooms are best used within three months for the best flavour and texture.
They’ll still be safe to eat after this time if they’ve remained frozen, but the mushrooms may become softer and more susceptible to freezer burn.
How To Defrost Stuffed Mushrooms
When you’re ready to use your stuffed mushrooms, defrost them in the fridge overnight, or for around four to six hours before cooking.
Avoid defrosting stuffed mushrooms on the kitchen worktop for long periods, as this allows them to spend too much time in the temperature danger zone where bacteria can multiply.
Can You Cook Stuffed Mushrooms From Frozen?
Yes. Uncooked stuffed mushrooms are particularly well suited to cooking straight from frozen.
Simply add around 10-15 minutes to the original cooking time. If the topping starts browning too quickly, loosely cover them with foil until the mushrooms are cooked through.
Always make sure the filling is piping hot before serving.
Reheating Cooked Stuffed Mushrooms
If you’re reheating stuffed mushrooms that were cooked before freezing, it’s worth loosely covering them while they warm through. This helps prevent the cheesy or breadcrumb topping from becoming too dark before the middle has heated through.
Cook until piping hot all the way through before serving.
Can You Cook Stuffed Mushrooms In The Air Fryer?
Yes! Stuffed mushrooms cook really well in the air fryer.
Whether you’re cooking them from thawed or frozen, keep an eye on them as air fryers can brown the topping quite quickly.
Every air fryer cooks a little differently, so use the cooking time as a guide and check regularly. As always, make sure the filling is piping hot before serving.
