Ingredients

  • 3-4 portobello mushrooms
  • 2 tablespoon avocado oil
  • 1 teaspoon garlic powder
  • ½ teaspoon onion powder
  • 1 teaspoon kosher salt
  • ½ teaspoon black pepper

Instructions

  • Using a barely damp paper towel, gently brush it along the surface of the mushroom to remove any dirt and debris. 
  • Give the front and back a good spray with avocado oil. Then sprinkle over the spice mixture of garlic powder, onion powder, kosher salt, and black pepper evenly over both sides of the mushrooms. 
  • Preheat your air fryer to 375F. Add the seasoned mushrooms to your air fryer basket in a single layer. Cook them for about 10 minutes, flipping half-way through. Cook time may vary based on the thickness of the mushrooms.
  • Slice the cooked mushrooms into strips and sprinkle with fresh chopped parsley.

Notes

  • Easily clean mushrooms by rubbing a damp towel over their top to remove any dirt and debris.
  • Air fry in a single layer – this will help make sure the mushrooms cook through and get tender on the inside and crispy edges. 
  • Mix up the seasonings – add or swap in cayenne, cumin, Italian seasoning, or chipotle powder. 
  • Use different fresh herbs – thyme, rosemary, cilantro, would all be great.
  • To test if your mushrooms are done, if you poke them with a fork or knife in the center if they are juicy and tender they’re done. 
  • If you don't have olive oil spray, you can use regular olive oil and then use a basting brush to make sure it gets all over the surface.
