Slice the French bread into desired lengths. Making sure it fits into your Air Fryer.
Brush generously with olive oil and sprinkle with garlic salt.
Air Fry at 400 degrees until bread is lightly toasted, 2 to 3 minutes.
Top with pizza sauce, mozzarella cheese, and pepperoni slices.
Place back into the Air Fryer and bake 5 minutes or until the cheese is melted and the crust is crispy. Checking halfway through baking time to ensure it doesn't burn and your toppings are in place.
Notes
Hint: Toasting the bread before topping helps prevent soggy pizza.
