Cut the French bread or half baguette in two and cut in half lengthwise.
Brush with olive oil each open face of the bread. Sprinkle some oregano if you prefer.
Place the bread in the air fryer and toast it at 375 degrees F for 3 minutes.
Top each bread with pizza sauce, shredded cheese and sliced pepperoni or any other toppings.
Air fry pizza at 375˚F for 3 minutes until the cheese is melted to your liking. Remove from air fryer with tongs and serve warm.
Notes
I used a half-baguette that weighs about 350g. These half-baguettes are shorter and wider than regular baguettes. Use regular ones if you can't find them.
Marinara sauce works as a substitute for pizza sauce.
