King oyster mushrooms are a type of edible mushroom, native to Europe, the Middle East, and Africa
King oyster mushrooms (Pleurotus eryngii) are a type of edible mushroom, native to Europe, the Middle East, and Africa. They are also widely cultivated in Asia, particularly in China, Japan, and Korea, where they are a popular ingredient. These mushrooms are prized for their unique flavour and texture and are a common culinary ingredient, especially in Italian, Chinese, and other Asian cuisines. They are also used in vegan recipes as a meat substitute.
King oyster mushrooms are the largest species in the oyster mushroom genus, Pleurotus. They are characterised by a thick, meaty white stem and a small tan or brown cap. They can grow up to 8 inches long and 2 inches in diameter. Unlike other oyster mushrooms, king oyster mushrooms have a traditional mushroom shape with a domed cap atop a stalk. Their stems are firm, dense, and edible, with a texture similar to scallops, abalone, and calamari.
King oyster mushrooms have a nutty, earthy, woody, and intensely umami flavour, with some seafood and licorice notes. They are relatively flavourless when raw, with a slightly metallic taste, but cooking them releases their flavour. They are versatile mushrooms that can be grilled, roasted, sautéed, broiled, or stir-fried. They can be sliced and prepared in various ways, such as pan-searing or threading onto skewers.
King oyster mushrooms are typically cultivated in indoor growing facilities or warehouses, where temperature, humidity, and carbon dioxide levels are carefully controlled. They are usually sold in plastic packaging, but it is recommended to store them in a paper bag in the refrigerator to extend their shelf life. These mushrooms are dense with nutritional value and are known for their unique textures and flavours, making them a popular ingredient in both home-cooked and gourmet meals.

King oyster mushrooms are a versatile ingredient that can be cooked in a variety of ways, including grilling, roasting, and sautéing. They are native to the Mediterranean regions of Europe, the Middle East, and Africa and are widely cultivated in Asia, where they are a popular ingredient in Chinese, Japanese, and Korean cuisines.
When grilling king oyster mushrooms, it is recommended to cut them into thick slices, about 1/2 inch (1-1.25 cm) thick. Scoring each side of the mushroom slices in a crisscross pattern is also suggested, as this helps the mushrooms absorb the marinade and cook more evenly. The mushrooms can then be tossed with seasonings such as soy sauce, oyster sauce, five-spice powder, and oil, and marinated for 20-30 minutes before grilling for about 3 minutes on each side.
For roasting, king oyster mushrooms can be sliced into thick, meaty pieces and arranged on a baking sheet. Drizzling them with butter, chicken stock, and olive oil, as well as seasoning with salt and pepper, can add to the flavour. The mushrooms are then roasted in the oven at 425°F for about 50 minutes, or until tender and lightly browned.
To sauté king oyster mushrooms, a mixture of olive oil and butter is recommended for the best flavour. The mushrooms are then cooked in this mixture, along with additional ingredients such as wine, teriyaki sauce, and garlic, depending on the recipe.
King oyster mushrooms have a meaty texture and a rich umami flavour, making them a popular substitute for meat and seafood. They can be used in a variety of dishes, including stir-fries, vegan scallops, and as a side dish or main component of a meal.

King oyster mushrooms are cultivated in warehouses, where temperature and humidity are controlled
King oyster mushrooms are a large member of the oyster mushroom family with a meaty texture and rich umami flavour. They are native to the Mediterranean regions of Europe, the Middle East, and Africa and are cultivated widely throughout Asia. They are also known as king trumpet mushrooms, French horn mushrooms, eryngi, king brown mushrooms, boletus of the steppes, trumpet royale, or aliʻi oyster.
King oyster mushrooms are cultivated in growing centres that resemble warehouses, where the temperature, humidity, and carbon dioxide levels are carefully monitored and controlled. The mushrooms grow in jars filled with organic material, which are then stored on trays stacked on shelves. This method of cultivation allows growers to create environments with the right balance of temperature, humidity, and nutrient-rich substrates, ensuring successful mycelial colonisation and fruiting. The consistent humidity and lower light levels create a microclimate that supports both mycelial expansion and the eventual emergence of fruiting bodies.
King oyster mushrooms are prized for their dense, chewy texture and unique flavour, making them a popular substitute for meat and seafood. They can be grilled, broiled, sautéed, roasted, or braised and served as a side dish or as the main component of a meal. They are also commonly used in vegan recipes, such as vegan "scallops" and "pulled pork".
Due to their cultivation in indoor growing facilities, king oyster mushrooms are available year-round. They are typically sold in plastic packaging, although this is not ideal for storage as the moisture expelled by the mushrooms becomes trapped, causing them to turn slimy and spoil. It is recommended to use king oyster mushrooms immediately or store them in a paper bag in the refrigerator for up to ten days.
