Button Mushroom is a small, round, white or off-white mushroom with a mild, earthy flavor and soft texture. Rich in protein, fiber, B vitamins, and antioxidants, it’s a nutritious, low-calorie food. Commonly used in stir-fries, curries, soups, pastas, and pizzas, button mushrooms absorb flavors well and add a delicious, meaty bite to vegetarian and non-vegetarian dishes alike.
