Thoroughly rinse the mushrooms under cold water in a colander to get rid of the dirt.
Use a damp paper towel to pat them dry; ensure they're as dry as possible so they don't release too much moisture while air frying.
Slice the mushrooms in half and slice the onions roughly ¼" in size.
16 oz whole white mushrooms, 1 red onion
Mix the clean mushrooms, onions, garlic powder, black pepper, rosemary leaves, and dried thyme in a bowl.
¼ teaspoon black pepper powder, ¼ teaspoon dried thyme leaves, ¼ teaspoon garlic powder, 1 teaspoon dried rosemary leaf whole
Add the sriracha hot sauce, salt, and olive oil. Mix well to get an even coating
salt to taste, 1 tablespoon sriracha hot sauce, 1 tablespoon olive oil
Preheat your air fryer to 400 degrees F (200 degrees C).
Add the mushroom mixture to the air fryer basket and spread it into a single layer.
Air fry for about 15 minutes, stirring or shaking the basket once or twice during cooking, until the mushrooms are golden brown and crispy.
Serve them immediately with your favorite dipping sauce or as a side dish. Enjoy!
