01 - Preheat air fryer to 400°F for 3 minutes before beginning preparation.
02 - Place eggplant cubes in a large bowl. Drizzle with olive oil or spray lightly for reduced calories. Add garlic powder, smoked paprika, oregano, salt, and black pepper. Toss thoroughly until all pieces are evenly coated.
03 - Arrange seasoned eggplant in a single layer within the air fryer basket. Cook in batches if necessary to avoid overcrowding.
04 - Air fry for 12-15 minutes, shaking the basket halfway through cooking. Continue until eggplant develops golden brown color and crispy edges.
05 - Transfer cooked eggplant to serving plate. Drizzle with lemon juice and sprinkle with fresh parsley if using. Serve immediately while hot.
