01 - Set the air fryer to 375°F (190°C) and allow it to preheat for 3 minutes.
02 - In a large mixing bowl, toss the peeled pearl onions with olive oil, salt, black pepper, garlic powder, and smoked paprika until each onion is evenly coated.
03 - Place the seasoned onions in the air fryer basket in a single layer, ensuring they are not overcrowded for even crisping.
04 - Cook for 10–12 minutes, shaking the basket halfway through the cooking time, until the onions develop a golden, crispy exterior and become tender inside.
05 - Transfer to a serving dish and enjoy immediately as a snack, appetizer, or alongside your favorite entrée.
