Preheat air fryer temperature to 400 degrees F, for 3-5 minutes, using air setting.
Line air fryer basket with parchment paper and spray with vegetable-based cooking spray.
Take the split 2 whole bagels and open them on a flat, clean surface.
Use a pastry brush to spread 2 tablespoons olive oil over the bready surface of the bagels.
Spread 1 cup marinara over the surface of the bagels in a thin, even layer.
Arrange 4 ounces fresh mozzarella cheese on each bagel slice on top of the marinara sauce.
Arrange Fresh basil leaves on top of the bagel slices.
Use a spatula to lift the bagels into the prepared air fryer basket. (You may need to cook in batches, if you’re using one of the smaller air fryers).
Cook for 5-7 minutes, at 400 degrees, or until edges of bagel are crispy and cheese is bubbly and golden brown.
Remove air fryer basket from air fryer and allow to cool on a heat-proof surface for 1- 2 minutes.
Use a rubber-tipped spatula to carefully remove the bagel pizzas to prevent scratching your air fryer basket. If desired, add more fresh basil to hot bagel pizzas.
