Step 1: Wash the zucchini thoroughly and trim off both ends. Do not peel. Cut the zucchini into uniform pieces, about 1/2 to 3/4 inch thick. You can make half-moons, sticks, or small cubes, ensuring consistency for even cooking.
Step 2: Place the cut zucchini in a large mixing bowl. Drizzle with olive oil and toss well until all pieces are lightly coated.
Step 3: Sprinkle the garlic powder, onion powder, dried oregano, salt, and black pepper over the zucchini. Toss again vigorously to ensure the seasonings are evenly distributed on all sides.
Step 4: Preheat your air fryer to 375°F (190°C) for 3-5 minutes. Preheating helps achieve a crispier exterior faster.
Step 5: Arrange the seasoned zucchini in a single layer in the air fryer basket. Do not overcrowd; cook in batches if necessary to allow hot air to circulate freely around each piece. Overcrowding will steam the zucchini instead of crisping it.
Step 6: Air fry for 12-18 minutes, shaking the basket every 5-7 minutes to ensure even cooking and browning. Cook until the zucchini is tender-crisp and beautifully golden brown.
Step 7: If using Parmesan cheese, sprinkle it over the zucchini during the last 5 minutes of cooking and continue to air fry until the cheese is melted and slightly golden.
Step 8: Carefully remove the crispy air fryer zucchini from the basket and transfer to a serving dish. Serve immediately and enjoy these healthy air fryer zucchini recipes!
