Quick, healthy, and delicious, this air fryer portobello mushrooms recipe comes together in only a few simple steps. They are perfectly browned and juicy, making for the easiest side dish ever. It is so easy to make portobello mushrooms in the air fryer!
Combine the soy sauce, sesame oil, garlic powder, onion powder, salt, and pepper in a bowl.
Add the portobello mushrooms, one at a time, to the mixture and toss to coat. A brush is helpful to get the mixture all over the mushrooms.
Spray some oil into the air fryer basket and place the portobello mushroom caps gill-side up into the air fryer. Feel free to spoon a bit of the leftover sauce into the gills (but not too much, or it’ll be salty!).
