Halve the jalapeños lengthwise and scrape out the seeds and white membranes. Wear gloves.
In a small bowl, mix the softened cream cheese, breadcrumbs, parsley, onion powder, and garlic powder until fully combined and smooth.
Spoon the filling into each jalapeño half, filling to just below the rim.
Wrap each stuffed half with a half slice of bacon, overlapping slightly, and tuck the end underneath.
Preheat the air fryer to 370°F for 3 to 5 minutes.
Arrange the poppers in the basket in a single layer, cheese side up, without crowding.
Air fry at 370°F for 6 to 8 minutes, until the bacon is crisp and browned. Add up to 2 minutes if needed.
Rest 3 to 5 minutes before serving. The filling will be extremely hot.
