Follow these simple steps to make the ultimate cheesy garlic bread:

1. Prep:
   Preheat your oven to 400°F (200°C). Cut the bread in half lengthwise. Line a baking sheet with foil to prevent sticking and make cleanup easier.
2. Mix:
   In a bowl, combine the softened butter, olive oil, minced garlic, salt, and pepper. Mix well until the ingredients are thoroughly combined.
3. Spread:
   Generously spread the garlic-butter mixture on the cut sides of the bread. Ensure even coverage for the best flavor. Wrap the bread in foil and place it on the prepared baking sheet.
4. Bake:
   Bake the bread in the preheated oven for 10 minutes. This allows the garlic-butter mixture to meld with the bread, creating a delicious base layer of flavor. Remove from the oven, unwrap the foil, and fold it back to expose the top of the bread.
5. Cheese Layer:
   Sprinkle the mozzarella and Parmesan cheeses evenly over the surface of the bread. Return the bread to the oven and bake for an additional 5-6 minutes, or until the cheese is melted and bubbly.
6. Crisp Finish (Optional):
   For a crispy, golden-brown top, switch your oven to the broil setting and broil the bread for 1-2 minutes. Keep a close eye on it to prevent burning.
7. Serve:
   Remove the bread from the oven and sprinkle with chopped fresh parsley. Slice it into pieces and serve warm for the best experience!
