Preheat oven to 425°F and line a large sheet pan with parchment.
Arrange the split bread cut side up. Brush with olive oil, then rub or spread on the minced garlic.
Season the bread lightly with salt and black pepper, then toast for 5 minutes to crisp the surface.
Spread pizza sauce evenly over the toasted bread, reaching the edges for coverage.
Top with mozzarella, layer on the pepperoni, and sprinkle Parmesan, Italian seasoning, and red pepper flakes.
Bake until cheese is melted and edges are golden, about 7–9 minutes. Broil 1 minute for extra browning if desired.
Rest 2 minutes, shower with fresh basil, then slice and serve hot.
Notes
Variation: Add thinly sliced bell peppers or red onion under the cheese for a veggie boost. Try a drizzle of hot honey or garlic butter after baking for a sweet-heat or extra-savory finish. Leftovers reheat best in a 375°F oven or toaster oven for 6–8 minutes to re-crisp.This recipe is an original creation inspired by classic Pepperoni Bread Pizza Recipes flavors.
