Clean the mushrooms with a damp cloth.
Don't wash them under water.
Pat them completely dry with paper towels.
Moisture makes them soggy, not crispy.
Put flour in one bowl.
Beat eggs in a second bowl.
Mix panko, ranch seasoning, garlic powder, and pepper in a third bowl.
This makes coating easy and organized.
Dip each mushroom in flour first.
Then dunk it in beaten eggs.
Finally, roll it in the panko mixture.
Press the coating gently so it sticks well.
Spray the air fryer basket with cooking spray.
Place mushrooms in a single layer.
Don't overcrowd them or they won't crisp.
Air fry at 400°F for 10 minutes.
Flip them halfway through cooking.
They should be golden and crispy.
