Preheat the oven to 200°C (180°C fan)

In a small bowl, mix the softened butter, soy sauce, and minced garlic together until well combined.

Slice the baguette in half lengthwise, then spread the soy sauce garlic butter mixture evenly over the cut sides.

Sprinkle the grated mozzarella over the top of the buttered baguette.

Place the baguette halves on a baking tray and bake in the preheated oven for 10-12 minutes, or until the cheese is melted and golden.

Remove from the oven and, if desired, sprinkle with fresh parsley for garnish.

Slice the baguette into halves or smaller pieces and serve warm.
