Preheat oven to 400°. Line a baking sheet with parchment paper.
Place frozen garlic bread cut side up on prepared pan. Spread pizza sauce onto bread, and sprinkle with Italian seasoning. Sprinkle 1 cup cheese onto sauce, and top with pepperoni. Sprinkle with remaining ½ cup cheese.
Bake until bread is hot and cheese is melted, about 7 minutes. Serve immediately.
