Clean the mushrooms. Remove the stems and the gills by scraping them with a spoon (optional).
In a small bowl, add olive oil, soy sauce, balsamic vinegar, garlic powder and pepper. Whisk to combine.
Pour the marinade into a shallow dish. Place the mushrooms and let them marinate on each side for 5 minutes. You can use a brush to apply marinade on both sides instead and let the mushrooms rest for about 5 minutes.
Meanwhile, preheat the air fryer at 390°F for about 5 minutes. Arrange the mushrooms (caps side down) in the air fryer basket in a single layer.
Air fry for a total of 8 minutes at 390°F flipping the mushrooms once halfway. Enjoy!
rinse the mushrooms under cold water only if they are very dirty, otherwise wipe the dirt off with a damp paper towel.
you do not have to remove gills. Whole mushroom is edible.
the cooking time and temperatures can be different depending on your air fryer.
