Preheat your oven to 375°F (190°C).
In a small bowl, mix the softened butter and minced garlic until well combined.
Spread the garlic butter mixture evenly over the cut sides of the baguette.
Top each side with shredded mozzarella and Parmesan cheese.
Place the baguette halves on a baking sheet and bake for 10-12 minutes, or until the cheese is melted and bubbly.
Garnish with chopped parsley, slice, and serve warm.
