Why King Oysters?

King Oyster mushrooms (Pleurotus eryngii) stand out from all other Oyster varieties. Instead of growing in delicate clusters, they form individually with thick, meaty stems and small tan-brown caps. The stems are the star of the show—dense, savory, and perfect for slicing into “scallops” or grilling as a plant-based steak.

Their flavor is mild and umami-rich, with a firm texture that holds up to roasting, grilling, sautéing, or braising. King Oysters also have a longer shelf life than most mushrooms, making them practical as well as delicious.

Timeline and Growth Cycle of King Oyster Mushrooms

1. Spore germination – begins at week 0.

2. Mycelium colonization – develops over 2–3 weeks (slower than smaller Oyster types).

3. Primordia (pinhead) formation – typically around weeks 3–4.

4. Young fruiting bodies – thick stems and small caps form by weeks 4–5.

5. Mature fruiting bodies – ready to harvest between weeks 5–7, depending on size preference.

6. Spore release – occurs after maturity; harvest beforehand for best flavor and texture.
