Yes, you can use frozen mozzarella on pizza! In fact, it can help create the perfect pizza. Frozen mozzarella has a higher moisture content than regular cheese, and this allows it to spread more evenly across the pizza surface when melted. This ensures that all slices have an even layer of cheesy goodness with no patches of cheese-free crust. Using frozen mozzarella also helps prevent burning—the high moisture content assists in slowing down cooking time so as not to overheat or char the cheese or crust. The flavor also tends to be milder in comparison to freshly shredded mozzarella which is beneficial if you are making a flavored topping like pepperoni or sausage as these will then be the most prominent flavors on your pie!
