King oyster mushrooms, also known as Pleurotus eryngii, are large, thick-stemmed mushrooms with a mild, savory flavor and firm texture. Their white, meaty stems are often used as a substitute for meat in plant-based dishes due to their hearty bite. These mushrooms can be grilled, sautéed, or stir-fried, absorbing flavors while maintaining a satisfying chew. King oyster mushrooms are a good source of protein, fiber, and various vitamins and minerals, making them a nutritious addition to many meals.
