01 - Preheat your air fryer to 375°F for 3 minutes.
02 - In a medium bowl, combine the cream cheese, cheddar, Parmesan, chives, garlic, onion powder, smoked paprika, black pepper, and salt. Mix until smooth and well combined.
03 - Fill each mini pepper half generously with the cream cheese mixture, smoothing the tops with a spoon.
04 - Arrange the stuffed peppers in a single layer in the air fryer basket. Cook for 8–10 minutes, or until the peppers are tender and the tops are lightly golden.
05 - Carefully remove from the air fryer. Let cool for 2–3 minutes, then transfer to a serving platter.
06 - Garnish with fresh parsley and a pinch of smoked paprika or red pepper flakes, if desired. Serve warm.
