01 - Preheat oven to 375°F. Line a baking sheet with parchment paper.
02 - Slice each baguette in half lengthwise. Hollow out the center of each half, forming a shallow boat with about 1/2 inch of bread remaining on the sides and bottom.
03 - Spread pizza sauce evenly into each bread boat.
04 - Sprinkle the mozzarella and cheddar cheese over the sauce in each bread boat.
05 - Distribute the pepperoni, diced bell pepper, chopped red onion, and black olives over the cheese. Sprinkle Parmesan evenly over each boat.
06 - Season each boat with dried oregano, garlic powder, and freshly ground black pepper.
07 - Place the prepared bread boats on the baking sheet. Bake for 15–20 minutes, until the cheese is melted and the bread is golden at the edges.
08 - Remove bread boats from the oven. Sprinkle with fresh basil or parsley, let cool slightly, then slice and serve.
