Preheat your oven to 375°F (190°C).
Cut the French bread in half lengthwise.
In a bowl, mix the softened butter and minced garlic until well combined.
Spread the garlic butter mixture evenly over both halves of the bread.
Sprinkle salt and pepper over the buttered bread.
Top with shredded mozzarella cheese and cheddar cheese generously.
Place the bread halves on a baking sheet.
Bake in the preheated oven for 10-15 minutes until the cheese is melted and bubbly.
For extra crispiness, broil for an additional 1-2 minutes.
Remove from the oven, sprinkle with fresh parsley, and cut into slices before serving.
