The thickness of the cut zucchini slices is the most important for determining cooking time and final texture. We find that cutting the zucchini into 1/2” or slightly thicker gives a great balance between browning the slices and cooking them through to be tender without being overly soft.
Trim the ends of the zucchini, if desired. Cut the zucchini into 1/2” thick slices (either into lengthwise slices or into coins). If cutting into lengthwise slices, cut to length to fit the width of your air fryer basket if needed.
Lightly oil or spray the zucchini slices on both sides and then season with garlic powder, salt and pepper.
Air Fry at 400°F for 8-14 minutes or until browned and cooked through.
