Preheat your oven to 350°F (175°C) and place the garlic bread loaf on a baking sheet.

Spread a generous layer of pizza sauce over the garlic bread, keeping in mind that the bread will absorb some of the sauce. Adjust the amount according to your preference for a saucier base.

Sprinkle the shredded mozzarella cheese evenly over the sauce. Arrange the pepperoni slices on top and finish with an additional sprinkle of cheese for good measure.

Bake in the preheated oven for 20-25 minutes, or until the cheese is bubbling and melted to perfection.

If desired, garnish with chopped parsley for a touch of color and freshness before serving. This step is optional but adds a nice visual appeal to your dish.
