To achieve a crispy pizza crust, you should place your oven rack in the lower section of the oven. The bottom position receives the most direct heat from the lower heating element, which is essential for baking the dough properly. For even heat distribution across the entire pizza, preheating your oven thoroughly for at least thirty minutes is required. However, you do not need to worry about the top rack at all, because the bottom heat is completely sufficient for both the crust and the toppings simultaneously.
