Freezing fresh mushrooms in a vacuum pack
Mushrooms (button, porcini, chanterelles, etc.) are delicate. Full of water and fragile, they oxidize, turn black, and become soft within a few days when exposed to air. How can you enjoy mushroom season all year round?
The solution is vacuum sealing, followed by freezing. This technique protects the mushrooms from oxidation and freezer burn, allowing them to be preserved for up to 10 months while retaining their flavor.
Can raw mushrooms be vacuum-sealed?
Yes, it's possible, but there's a trick. Raw mushrooms are like sponges. If you vacuum-seal them directly with a powerful machine, you risk crushing them.
Chef's tip: For best results, we recommend cooking (sautéing) or blanching your mushrooms before vacuum sealing. This seals in their moisture and preserves their texture. If you prefer to keep them raw, be sure to use a vacuum sealer with a manual pulse function.
Table for preserving mushrooms under vacuum
Here's how long you can keep your mushrooms using vacuum sealing:
| State of the mushrooms | Vacuum-sealed in the refrigerator (4°C) | Vacuum-sealed in the freezer (-18°C) |
|---|---|---|
| Raw Mushrooms | 7 to 10 days | 8 to 10 months |
| Cooked/Sautéed Mushrooms | 10 to 15 days | 10 to 12 months |
| Dried Mushrooms | 12 months (Closet) | Useless |
Don't turn your porcini mushrooms into a puree!
Mushrooms are fragile. To pack them without crushing them, use our 290W machine equipped with the "Pulse" function (manual control).

To prevent them from becoming soft or black, follow these steps:
-
Cleaning: Do not soak the mushrooms! Brush them or wipe them with a damp cloth. If they are waterlogged, they will not cook properly.
-
Preparation (Recommended): Slice them and sauté them in a pan for a few minutes to evaporate the water. Let cool.
-
Vacuum sealing: Place them flat in a corrugated bag. If the mushrooms are raw, use the "Pulse" mode to stop the vacuuming before they are compressed.
-
Storage: Place the bag in the freezer. They will be ready to be thrown directly into the pan (without thawing first) for your future omelets or risottos!

Bonjour,
Est-il possible de conserver les cèpes simplement coupés, mis sous vide, et mis au réfrigérateur à 5 degrés, plus de 4 semaines ?
Dans l’affirmative, est-il possible après de les mettre au congélateur?
La raison de cette question: les cèpes sont cueillis dans le sud ouest, ou j’habite une partie de l’année. Je voudrai ensuite les emmener à mon domicile parisien et les mettre au congélateur. Je ne peux pas les congeler avant car ils se décongèleront avant d’arriver, ne pouvant pas faire le voyage dans la journée.
Est-il possible de les garder plus d’un an au congélateur alors qu’ils sont sous vide?
Merci d’avance pour votre réponse.
Bien à vous,
JCS
