You are correct; it is not advisable to place frozen pizzas directly on the middle oven rack without any support. While some pizza brands may suggest this on their packaging, it's important to clarify what they actually mean.
When the packaging instructs you to place the frozen pizza directly on the middle oven rack, it typically means you should not use a baking sheet or pizza stone. Instead, the pizza should be placed directly on the oven rack to allow for proper heat circulation and to achieve a crispy crust.
However, it's essential to use a pizza pan or a pizza screen underneath the pizza to catch any drips or potential spills. Placing the pizza on a rack without any support could result in a mess inside your oven as the cheese and toppings melt and spread.
Here's a safer way to follow the instructions on the packaging:
- Preheat your oven to the recommended temperature mentioned on the pizza packaging.
- If you have a pizza pan, place the frozen pizza on the pan to catch any drips and make handling easier.
- If you don't have a pizza pan, you can use a pizza screen or a baking sheet instead. The pizza screen allows for better airflow and even cooking.
- If using a baking sheet, you can either lightly grease it or use parchment paper to prevent sticking.
By following these steps, you can still achieve the desired crispy crust while minimizing the mess and making it easier to remove the pizza from the oven. Always refer to the specific instructions on the pizza packaging and use your best judgment to ensure a successful and safe cooking experience.
