Preheat the oven to 450 degrees.

Cut the french bread loaf in half. Place cut side up on a metal baking sheet, lined with parchment paper, set aside.

In a small bowl combine softened butter, olive oil, garlic powder, Italian seasoning and sea salt. Spread evenly over the bread. Sprinkle with 1/2 cup parmesan cheese, 1/4 cup per french bread loaf half. Bake for 7-8 minutes, until just crispy around the edges.

Remove from the oven and add the pizza sauce, followed by mozzarella cheese, pepperoni and desired toppings. Return to the oven and bake for another 10-12 minutes, until cheese is melted and bubbly. Let sit 5 minutes before cutting and serving.
