Preheat the air fryer to 350°F (if your model has that option)
Slice the french bread in half length-wise, and then slice each piece in half again, so you should end up with four pieces.
Drizzle olive oil over each piece of bread and then sprinkle with Italian seasoning and garlic powder.
Place the bread slices in the air fryer and cook for 3 minutes to get the bread crisp. You may need to work in batches.
Remove bread, top each piece with pizza sauce, shredded cheese, pepperoni, and oregano.
