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 a lower calorie option. 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, which prevents proper crisping.
04 - Air fry for 12 to 15 minutes, shaking the basket halfway through cooking time. Continue until eggplant reaches golden brown color with crispy edges.
05 - Transfer cooked eggplant to a serving plate. Drizzle with lemon juice and sprinkle with fresh parsley if desired. Serve while hot for optimal texture.
