Preheat the air fryer to 360°F (180°C) if your model requires preheating.
Arrange the frozen garlic Texas toast in a single layer inside the air fryer basket.
Spread a thin layer of pizza sauce over each slice.
Sprinkle mozzarella cheese evenly over the sauce.
Add pepperoni and any additional toppings you like.
Air fry at 360°F for 5 minutes, or until the cheese is melted and bubbly and the bread is crispy around the edges.
Carefully remove the pizza toast from the basket.
Let it cool for 1 minute before serving.
