Cut the king oyster mushrooms lengthwise and rinse under running water. Pat dry with a kitchen towel.

Place 1/2 cup of pancake mix into a plastic bag, add the mushrooms, and shake vigorously to coat them evenly.

Shake off excess pancake mix inside the bag and remove the mushrooms.

Optionally, mix chopped vegetables like carrots or chives into the beaten eggs for added flavor.

Dip the flour-coated mushrooms into the egg mixture, ensuring they are fully covered.

Heat a frying pan with a generous amount of oil and fry the mushrooms until golden brown on both sides.
