Prepare the garlic butter: In a small bowl, combine softened butter, minced garlic, olive oil, parsley, and oregano. Stir until well blended and aromatic. You want the butter to be creamy enough to spread easily and carry all that garlicky flavor in every bite.
Prepare the bread base: Preheat your oven to 400°F (200°C). Slice the French bread in half lengthwise and place both halves cut-side up on a lined baking sheet. Lightly toast them in the oven for 3–4 minutes, just until the surface is slightly crisp — this keeps the bread from getting soggy once you add the toppings.
Add the garlic butter: Remove the bread from the oven and generously spread the garlic butter mixture across the cut sides. Make sure to cover the edges too — that’s what gives you that golden, crispy crust.
Assemble the pizza: Spread a thin layer of pizza sauce over the buttered bread. Then sprinkle on the mozzarella, cheddar, and Parmesan cheese evenly. If you love extra cheesiness, add a little more mozzarella on top for that classic pizza pull.
Bake the pizza: Return the bread to the oven and bake for 10–12 minutes, or until the cheese is melted, bubbly, and lightly browned on top. If you want an extra toasty finish, switch your oven to broil for the last 1–2 minutes (watch closely so it doesn’t burn).
Garnish and serve: Remove from the oven, sprinkle with extra parsley or red pepper flakes for a bit of spice, and let it cool slightly before slicing. The aroma of buttery garlic and melted cheese makes it hard to wait, but giving it a minute helps everything set beautifully. Serve warm, sliced into thick pieces — every bite is a combination of crisp bread, gooey cheese, and rich garlic butter flavor.
