Hello there! I'm an expert in kitchenware and cooking techniques, and I'm here to help you navigate through the nuances of using Pyrex pie plates and the safety of transitioning them from the freezer to the oven.

Firstly, it's important to understand the material that Pyrex is made of. Pyrex is a type of borosilicate glass that is known for its ability to withstand significant temperature changes without breaking. This is due to its low thermal expansion coefficient, which means it doesn't expand or contract as much as other types of glass when heated or cooled. This property makes Pyrex an excellent choice for various cooking and baking applications, including the use in ovens and freezers.

However, when it comes to moving a Pyrex pie plate from the freezer to the oven, there are a few considerations to keep in mind:


1. Thermal Shock: Sudden and extreme temperature changes can cause thermal shock, which may lead to the glass cracking or breaking. Although Pyrex is more resistant to thermal shock than regular glass, it's still not recommended to subject it to such drastic changes without proper preparation.


2. Preheating the Oven: If you're planning to bake a pie that has been stored in the freezer, it's advisable to preheat your oven first. This allows the pie to start baking in a warm environment, which can help to mitigate the risk of thermal shock.


3. Gradual Temperature Change: Ideally, you should allow the pie to thaw in the refrigerator before moving it to the oven. This gradual temperature change reduces the risk of thermal shock. However, if you're in a hurry and must bake a frozen pie, it's crucial to monitor the pie closely to ensure it heats evenly and doesn't crack.


4. Quality of Pyrex: Not all Pyrex products are created equal. Older Pyrex is often considered to be of higher quality and more resistant to thermal shock than newer versions. If you have an older Pyrex pie plate, it may be more forgiving when it comes to temperature changes.


5. Proper Handling: Ensure that you handle the Pyrex pie plate with care. Any cracks or chips in the glass can weaken its structure and make it more susceptible to breaking.


6. Cooking Time and Temperature: When baking a pie that has been taken directly from the freezer, you may need to adjust the cooking time and temperature. The pie will take longer to cook, and you might need to lower the oven temperature to prevent the crust from burning while the rest of the pie cooks.

7.
Personal Experience: While some people have reported success with baking frozen pies directly in the oven without any issues, it's important to remember that experiences can vary. What works for one person might not work for another, and there's always a risk involved.

8.
Safety Precautions: Safety should always be your top priority. If you're unsure about the safety of moving a Pyrex pie plate from the freezer to the oven, it's better to err on the side of caution and allow the pie to thaw first.

In conclusion, while it's possible to bake a Pyrex pie plate that has been taken directly from the freezer to a preheated oven, it's not without risks. To minimize these risks, it's recommended to allow the pie to thaw gradually in the refrigerator, preheat your oven, and monitor the baking process closely. By taking these precautions, you can enjoy a delicious pie without the worry of a Pyrex disaster.

DO NOT DEFROST THE PIE BEFORE BAKING! Be strong, put the FROZEN pie directly into the preheated (or heating) oven. ... I can't guarantee that a pyrex/glass pie pan has never broken going from freezer to oven but it's never happened to me.Mar 27, 2014read more >>
