Preheat oven to 400 degrees F and line a baking sheet with a silicone baking mat.
In a medium sized bowl, mix together melted butter, oil, garlic, parmesan, parsley, basil, salt, and pepper until well combined. Taste and re-season, if desired.
Spread the mixture evenly over the two halves of bread.
Sandwich the two halves back together and wrap in tin foil.
Place onto the prepared baking sheet and bake in preheated oven for 15-20 minutes, or until the bread is hot.
Unwrap the bread, open up the slices and bake for an additional 5 minutes on the prepared baking sheet to lightly crisp the bread.
Sprinkle with additional salt, if desired, then slice and serve warm!
