When your pizza arrives looking a little different—covered in raised bubbles under the cheese—it can catch you off guard. Those shiny, dome-like spots might seem unusual at first, especially if you’re used to a smoother surface. But before you assume something’s wrong, it’s worth taking a closer look.
Those bubbles are actually a natural result of the baking process. As the pizza cooks, heat causes air and moisture trapped in the dough and toppings to expand. This creates pockets that lift the surface, forming the uneven texture you’re seeing. It’s especially common in fresh, hand-stretched dough or pizzas baked at high temperatures, where rapid heat encourages these air pockets to develop.
