Canning & Pickling Mushrooms
Preserving and Pickling Mushrooms
Pickling in Vinegar
Suitable for: button mushrooms, porcini, chanterelles
Basic recipe for 1 kg mushrooms: 500 ml white wine vinegar, 500 ml water, 2 tsp salt, 1 tsp sugar, bay leaf, pepper, mustard seeds.
- Blanch mushrooms for 3 min., drain
- Bring the brine to a boil, simmer mushrooms for 5 min.
- Fill into sterilized jars, pour hot brine over them
- Shelf life: 12 months, cool and dark
Preserving in Oil
⚠️ The BfR advises against preserving and storing mushrooms and vegetables in oil. Oil excludes oxygen – precisely the environment in which Clostridium botulinum thrives. The common rule "always keep covered with oil" protects against mould, not against botulism.
If you still want to do it:
- Blanch mushrooms, drain on a cloth for 24 h
- Layer with herbs and garlic
- Cover completely with olive oil
- Keep refrigerated and use up promptly – do not store for months
Canning (Boiling in Jars)
⚠️ Mushrooms are low-acid – an automatic canner does not make them spore-free, not even after 90 minutes. Safe preservation requires a pressure canner (121 °C); without one, heat twice to 100 °C, one to two days apart (BfR: lowers the risk considerably, does not eliminate it).
- Sauté mushrooms, season with salt, fill preserving jars three-quarters full
- Pressure canner per manufacturer instructions – or twice for 90 min. at 100 °C, one to two days apart
- Shelf life: 12 months
- Heat right through before eating

Always sauté chanterelles briefly before freezing them – frozen raw, they turn bitter.
