King Trumpet mushrooms are medium to large in size and are easily identified by their thick cylindrical stem and their small, flattened cap.

King Trumpet mushrooms are best suited for cooked applications such as grilling, roasting, baking, sautéing, and frying. They can be sliced or torn into thick pieces and simmered or braised to create a crispy texture, or they can be cut into rounds to develop a tender, meat-like consistency. King Trumpet mushrooms are commonly used in stir-fries, soups, stews, tempura, chopped into meatballs or meatloaf, mixed into pasta, or grilled and served on top of barbequed meats.

King Trumpet mushrooms contain riboflavin, vitamins B6, C, and D, niacin, potassium, fiber, and folate. They also contain high amounts of a naturally occurring amino acid, ergothioneine, which is an antioxidant. This particular antioxidant is stored in organs like the liver and kidneys and helps reduce the risk of chronic disease.
