01 - Set the air fryer to 375°F and allow it to preheat for 3 minutes.
02 - In a large mixing bowl, toss the peeled pearl onions with olive oil, salt, pepper, garlic powder, and smoked paprika until every onion is evenly coated.
03 - Spread the seasoned onions in a single, even layer inside the air fryer basket to ensure proper air circulation and even crisping.
04 - Cook for 10 to 12 minutes, shaking the basket halfway through the cooking time, until the onions develop a golden, crispy exterior and become tender inside.
05 - Transfer the hot pearl onions to a serving dish and enjoy as a snack, appetizer, or side alongside your favorite main course.
