Preheat air fryer to 380°.
Prep a baking sheet with parchment or foil. Set aside. Preheat the oven to 200 degrees.
Using gloves, slice each jalapeno in half and deseed. Set aside.
In a medium bowl, combine the cheddar cheese, cream cheese, mayonnaise, bacon, pickled jalapeños, onion and about half of the garlic salt and half of the paprika. Stir well to combine. Set aside.
In another smaller bowl, combine the panko bread crumbs with the remaining garlic salt and paprika. Stir to combine, set aside.
Using a spoon, fill each jalapeño with the cheese filling and press into the jalapeño - again, gloves are highly recommended while continuing to handle the peppers. Set aside.
Sprinkle the filled jalapeños with the Panko mixture.
Place 6-8 filled peppers in the basket of the air fryer - leaving at least an inch between each popper. Work in batches if necessary.
Cook in the air fryer at 380 degrees for 6-7 minutes.
Remove the jalapeños from the basket and place on the prepared baking sheet. Place in the preheated oven to keep warm while working through the rest of the poppers in the air fryer.
Serve immediately with ranch as a dipping sauce, if desired.
