Set an oven rack on the bottom position and preheat the oven to 450 degrees F.
Melt the butter in a pan with the garlic and bring to a simmer. Brush the garlic butter over the bread, lay slices of the mozzarella on top and sprinkle with the chopped parsley.
Put the bread onto a baking sheet and cook on the bottom rack for about 10 minutes.
