Preheat the air fryer to 400 degrees F for 5 minutes.
Meanwhile, trim the stem and base ends off of the zucchini, then cut it in half lengthwise. Cut it into 3/4-inch pieces and place in a medium bowl.
Drizzle the olive oil over the zucchini. Season with thyme, salt and peppers and toss to coat.
Place the zucchini in a single layer in the air fryer basket and cook for 5 to 8 minutes until tender, tossing once during the cook time.
Serve warm with lemon wedges and Parmesan, if desired.
Notes

Freezing is not recommended.Reheating: To reheat, add the air fried zucchini back to the air fryer and cook on 400°F for about 60-90 seconds or until warmed through.
