Make 3 evenly spaced cuts across the top of the bagel, being careful not to cut all the way through. This should divide the bagel into 6 sections.
Using a hand mixer, in a medium bowl, whip the cream cheese until fluffy. Put the cream cheese into a piping bag. Fill each cut bagel section with cream cheese.
In a small bowl, add melted butter, parsley, and garlic. Whisk together to combine.
Brush the garlic butter over top of the bagels. Sprinkle Parmesan cheese and mozzarella on top.
Place in the preheated air fryer and cook for 5 to 7 minutes or until golden and the cheese has melted.
Notes
Note: Swap the bagel for your favorite kind like everything bagel or sesame. You can also use a herb and garlic cream cheese if you want some extra garlicky flavor. If you don't have a piping bag, you can use a ziploc bag and cut the corner off. Leftovers will keep in an airtight container for 2 days, and in the freezer for 1 month.
