Preheat your air fryer to 350° F. Wash your zucchini thoroughly under cold water to remove any debris.

Start by cutting the ends off of each zucchini and discarding them. Next, cut each zucchini in half lengthwise. Now slice the zucchini into thin slices, about ½ inch each. 

Place the sliced zucchini into a large bowl and drizzle in the olive oil. Now add the seasonings including the all purpose seasoning (or seasoned salt), the garlic powder, onion powder, and black pepper. 

Use tongs or a spoon to toss the zucchini in the bowl to ensure each piece is fully coated by the olive oil and seasoning. 

Add the seasoned zucchini to a piece of parchment paper or aluminum foil, try to place them in one even layer if possible. Now place it in the air fryer. 

Air fry the zucchini for 7 minutes at 350º F. Open the air fryer and use the tongs to gently turn the zucchini. Air fry for an additional 7 minutes. Serve right away, and enjoy!
