Return the pizza to the oven. Bake until the cheese is melted and bubbly. Fresh mozzarella does not really brown; after 5 minutes check the pizza. If the cheese is melted, it is done. If not, bake for a little longer. Remove from the oven and return to wire rack. Allow to cool for 5 minutes before serving.
