Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper or aluminum foil for easy cleanup.

Slice the loaf of bread in half lengthwise using a serrated knife so you have two long, open-faced halves.

In a small mixing bowl, combine the softened butter, minced garlic, chopped parsley, dried oregano, salt, and pepper until well blended.

Spread the garlic butter mixture evenly over the cut sides of both bread halves, ensuring you reach the edges for maximum flavor.

Place the buttered bread onto the prepared baking sheet and bake for 10 minutes, or until the butter has melted and the edges begin to toast lightly.

Remove the baking sheet from the oven and sprinkle the mozzarella and Parmesan cheeses generously over the top of the hot bread.

Return the bread to the oven and bake for another 3-5 minutes, until the cheese is fully melted and bubbly.

For a golden-brown finish, switch the oven to broil for the last 1-2 minutes, watching closely to prevent burning.

Remove from the oven, let it cool for a minute to set the cheese, then slice crosswise into 2-inch strips and serve warm.
