King Trumpet Mushroom (Pleurotus eryngii)

Appearance

The King Trumpet mushroom, also known as King Oyster, is the largest member of the Pleurotus genus. It features a thick, robust white stem and a small, trumpet-shaped tan cap. The meaty and firm texture of its large stem is the most distinctive feature, making it a standout among other mushrooms.

Growing Conditions

All our mushrooms are grown in a controlled, sterile, and enclosed environment. No need for washing prior to use. You may rinse them under running water if desired prior to cooking. Be sure not to rise prior to storage as excess moisture can lead to faster spoilage.

Texture and Flavor

King Trumpet mushrooms are known for their dense, chewy texture, which closely resembles meat or seafood, earning them a reputation as a great plant-based substitute. When cooked, they have a mild, savory flavor with umami undertones and a subtle nutty richness. Their hearty texture makes them ideal for dishes where a meatier mushroom is needed.

Health Benefits and Nutrient Profile

These mushrooms provide a host of nutritional and health benefits:

  • Rich in antioxidants: High in L-ergothioneine, an amino acid that helps fight free radicals, oxidative stress, and supports brain and cardiovascular health.

  • Cholesterol management: Contains ergostane-type sterols and polysaccharides that may help lower cholesterol levels and support cardiovascular health.

  • Anti-cancer potential: Studies suggest they may reduce the risk of certain cancers, such as breast cancer, thanks to their bioactive compounds.

  • Bone health: King Trumpet mushrooms may help reduce the risk of osteoporosis by protecting against bone loss.

  • Low in calories: They are a low-calorie food rich in dietary fiber, making them ideal for weight management.

  • Vitamins and minerals: A good source of B vitamins, particularly niacin, riboflavin, and pantothenic acid, as well as vitamin D and potassium.

Storage and Shelf Life

Store King Trumpet mushrooms in a paper bag in the refrigerator for up to 10 days. Their dense, firm structure gives them a longer shelf life compared to more delicate mushroom varieties. For optimal freshness, avoid washing them before storage.

Seasonality

King Trumpet mushrooms are available year-round due to widespread cultivation, especially in Asia, Europe, and North America. Native to the Mediterranean and North Africa, they are now grown globally.

Pairing Suggestions

King Trumpet mushrooms pair well with:

  • Asian flavors: Soy sauce, miso, ginger, garlic, and sesame oil enhance their umami flavor.

  • Seafood alternatives: Their texture works well in dishes like vegan scallops or seafood replacements.

  • Hearty grains and vegetables: Pair with wild rice, farro, or root vegetables for an earthy, filling dish.

  • Lemon and cream sauces: Their mild flavor complements creamy, citrusy sauces beautifully.

Recommended Cooking Methods

  • Sautéing and frying: Their meaty texture holds up well in high-heat cooking methods like sautéing or pan-frying. Try thick slices seared as a vegan scallop alternative.

  • Grilling or roasting: Brush with olive oil, season, and grill or roast to enhance their natural savory flavor.

  • Braising: Braised King Trumpets take on the flavors of the liquid, becoming tender and juicy while retaining their robust texture.

  • Grating or slicing: Thinly slice or grate and use in stir-fries, soups, or as a garnish for added umami.
