Oyster Mushroom: what every chef needs to know
Open any well-stocked walk-in and chances are you will find Oyster Mushroom — a cultivated edible mushroom with a fan- or oyster-shaped cap white to grey-beige colour and a soft, mild flavour with a light anise nuance. Oyster mushrooms are grown on straw, wood chips or coffee grounds and are available year-round. They have a fine, fibrous structure that cooks quickly and retains a light, meaty texture. Oyster mushrooms are an excellent source of protein (3.3g/100g), contain all essential amino acids and are one of the most protein-rich mushrooms. Rich in vitamin B3, potassium and ergothioneine. The pink oyster mushroom and yellow oyster mushroom are culinarily comparable but visually distinctive.

Oyster Mushroom: preparation techniques
Exact temperatures and times for HACCP compliance. Core temperature is leading for poultry and pork.
Heat the pan well before adding the oyster mushrooms; the mushrooms release moisture quickly: high heat and don't overcrowd the pan for browning rather than boiling.
Best preserves the delicate flavour and texture; suitable as a side dish with fish; season lightly with sea salt and lemon juice after cooking.
Sear in butter, than add cream with thyme and shallot; the mushrooms absorb the cream sauce for a rich, creamy texture.
Dip in tempura batter or light flour, fry in small batches until crispy; serve immediately for maximum crispiness.

Frequently asked questions about Oyster Mushroom
How do I clean oyster mushrooms?
Do not wash oyster mushrooms: they absorb water quickly. Clean with a damp cloth or soft brush. Trim the tough stem at the attachment point. Tear larger specimens lengthways for a more rustic texture.
Are oyster mushrooms a good protein source for vegetarians?
Yes, oyster mushrooms contain 3.3g protein per 100g and have a relatively complete amino acid profile. They are not a complete replacement for animal protein (lower bioavailability), but contribute meaningfully to a protein-rich plant-based meal.
What is the difference between oyster mushroom and shiitake?
Oyster mushroom (Pleurotus ostreatus) grows in clusters, has a mild, lightly anise-like flavour and a soft texture. Shiitake (Lentinula edodes) has a stronger, umami-rich flavour, a firmer texture and a characteristic cap shape with a brown top.
At what temperature should you store Oyster Mushroom?
Store Oyster Mushroom at 4-6°C, compliant with EU Regulation 852/2004 and Codex Alimentarius guidelines.

Allergen information: Limitations
The allergen information on this page relates to the ingredient as such. The actual allergen composition of your purchase may differ due to:
- Varying suppliers, production facilities or growing regions;
- Cross-contact during production, transport or storage ("may contain");
- Changed product formulations not yet reflected in public sources;

Milk allergen and lactose intolerance
The EU-14 allergen "Milk (including lactose)" covers two distinct conditions, both of which require declaration: (1) cow's milk allergy, an immunological reaction to milk proteins (casein, whey), and (2) lactose intolerance, an enzymatic deficiency (lactase) preventing digestion of milk sugar. Both groups must be informed separately on the menu. Lactose-free is not the same as milk-protein-free: a guest with cow's milk allergy may still react to lactose-free products.
