To Air Fry: Place the pizza bagels in your air fryer basket and air fry at 400°F for 8-10 minutes or until the cheese is bubbly and golden brown. Make sure the bagel halves aren't overcrowded and have some space between them. Keep an eye on the bagels while they're cooking to prevent them from burning. Depending on the thickness of your bagels and your air fryer, the cooking time may vary, so check them periodically.
