The safest way to move Pyrex from the fridge to the oven allow the Pyrex dish to come closer to room temperature before placing it in. This will make sure that the Pyrex will not suffer from thermal shock and break when it heats up in the oven. Preheat the oven before you put your Pyrex dish in the oven to avoid exposing it to extreme temperature changes.
Pyrex is generally thermal shock resistant sudden and extreme temperature changes can potentially cause it to break or crack. Do not put pyrex dishes with plastic lids in the oven as they can melt.
Key Takeaways
- Pyrex can go from fridge to oven, but it is important to avoid sudden temperature changes.
- Always read the manufacturer’s instructions and use caution when using Pyrex in the oven.
- Certain Pyrex dishes may come with plastic lids that are not safe for use in the oven.
Temperature Tolerance of Pyrex
Pyrex is a popular brand of glassware that is commonly used for cooking and storing food. It is known for its durability and ability to withstand high temperatures. However, it is important to understand the temperature tolerance of Pyrex to ensure that it is used safely.
The original form of Pyrex is made from borosilicate glass, which is known for its thermal shock resistance. This means that it can withstand sudden and extreme changes in temperature without breaking or cracking. However, newer versions of Pyrex may be made from tempered soda-lime glass, which is not as resistant to thermal shock.
It is generally safe to put Pyrex from the fridge to the oven as long as it is done properly. Before placing Pyrex in the oven, it should be allowed to come closer to room temperature. This can be done by taking it out of the fridge and letting it sit on the counter for a while. Preheating the oven is also important to ensure that the Pyrex is not exposed to extreme heat conditions.
It is important to note that Pyrex should not be placed directly on a hot stove or burner. Doing so can cause it to crack or break. Additionally, Pyrex dishes that come with plastic lids should not be used in the oven as the lids are not safe for high temperatures.
How to Reheat Food in Pyrex in the Oven
One of the best tips is to make sure that your Pyrex dish is close to room temperature before you place it in the oven. While you do not want to leave any food sitting on your bench for too long, doing so for a short period of time will protect your Pyrex from thermal shock from extreme temperature changes.
It is best to follow these 3 steps when reheating food in Pyrex.
- Transfer your food to the Pyrex dish.
- Place the dish in the fridge if you are defrosting frozen food and allow it to reach fridge temperature.
- Place the Pyrex dish on your bench for a short time to come closer to room temperature.
- Reheat the Pyrex dish in a preheated oven or in the microwave. Remember to remove the plastic lid if using the oven or opening it at one corner if using the microwave.

Impact of Sudden Temperature Changes on Pyrex
When it comes to Pyrex glassware, sudden and extreme temperature changes can potentially cause it to break or crack. This is known as thermal shock, which occurs when there is a significant difference in temperature between two parts of the glassware.
Thermal Shock
Pyrex glass is generally thermal shock-resistant, but it is not completely immune to it. The risk of thermal shock can be reduced by following Pyrex Glassware guidelines, which recommend avoiding sudden temperature changes.
If you need to move a cold Pyrex dish from the fridge to the oven, it is important to allow it to come closer to room temperature first. Placing a cold Pyrex dish directly into a hot oven can cause it to shatter.
Risk of Breakage
The risk of breakage can also be influenced by the manufacturing process. Borosilicate glass Pyrex dishes undergo a special manufacturing process that imparts them with higher thermal shock resistance. This process involves adding boron oxide to the glass mixture, which reduces the risk of breakage.
It is important to note that not all Pyrex dishes are made with borosilicate glass. Some Pyrex dishes may be made with tempered soda-lime glass, which is less resistant to thermal shock.
In conclusion, while Pyrex glassware is generally safe for use in the fridge and oven, it is important to handle it with care to avoid thermal shock and breakage.
If you need to move a Pyrex dish from the fridge to the oven, make sure to allow it to come closer to room temperature first. Additionally, consider purchasing Pyrex dishes made with borosilicate glass for added thermal shock resistance.
Moving Pyrex From Fridge to Oven – Key Tips
Check out these easy tips to safely move your Pyrex from your fridge to the oven.
1. Pre-heat the Oven for Pyrex
It is important to always preheat your oven before placing the Pyrex dish inside. This will avoid exposing the Pyrex dish to extreme temperatures when the oven is heating up.
When preheating, ovens will blast very hot air, above the set temperature to rapidly heat it. These high temperatures will place your Pyrex under extreme stress and may cause it to break.
When transferring your Pyrex from your fridge, bench and then to the hot oven, always wait until the oven has pre-heated and reached the desired temperature before placing it in.
2. Allow Pyrex to Adjust in Temperature Before Placing it in the Oven
After removing Pyrex from the fridge it is a great idea to allow it to warm slightly to room temperature before placing it in the oven. Sit it on your kitchen bench for 15-30 minutes. Once the oven has preheated you can then place the dish in the oven to cook. The food should then be reheated in the oven to a hot, steaming temperature or until cooked through.
It is important to avoid keeping food out of your fridge for longer than 1-2 hours. This will avoid excess bacterial growth. On very hot days, the time spent on the bench should be even shorter.
How to Prevent Pyrex Shattering in the Oven
To reduce the risk of your Pyrex dish shattering in the oven avoid any extreme changes in temperature. This means it is best not to place a frozen Pyrex dish straight from the freezer or fridge into the oven or microwave oven. This sudden change in temperature can put extra stress on the glass and it may shatter or break.
The best way to avoid your Pyrex dish shattering this is to defrost your food in the refrigerator a day before you need it. Simply move your Pyrex dish to the fridge to defrost 24 hours before you need to cook it. You can then allow the container to get to room temperature before re-heating in the oven or microwave.
Tips for Handling Hot Pyrex
One of the primary risks of using Pyrex from the fridge to the oven is the possibility of thermal shock. Thermal shock occurs when there is a sudden change in temperature, causing the glass to expand or contract rapidly. This can cause the glass to crack or shatter, which can be dangerous.
To avoid thermal shock, it is essential to handle hot Pyrex with care. Always use oven mitts or a thick towel to handle hot dishes, and never place hot Pyrex on a cold surface or in cold water. Allow the dish to cool down gradually before washing it or placing it in the fridge.
Pyrex Cleaning and Maintenance
Another risk associated with using Pyrex from the fridge to the oven is the possibility of damage caused by improper cleaning and maintenance. Pyrex is a durable material, but it can still be damaged if not cared for properly.
To avoid damage, always clean your Pyrex dishes with a soft sponge or cloth and mild soap. Avoid using abrasive cleaners or scrubbers, which can scratch the glass and weaken it over time. Additionally, never stack Pyrex dishes on top of each other, as this can cause them to scratch or chip.
In conclusion, using Pyrex from the fridge to the oven is generally safe as long as you take the necessary precautions. By handling hot Pyrex with care and maintaining your dishes properly, you can enjoy the convenience of using Pyrex for both storage and cooking.
How to Defrost Food in Pyrex in the Fridge
The best way to defrost food in Pyrex is to take it out of the freezer a day before you would like to use it. Simply place the Pyrex dish in your refrigerator around 24 hours before, and this will allow the food to safely come to refrigerator temperature (0-4 degrees Celsius or at or below 40 degrees Fahrenheit).
Transfer the Pyrex dish to your bench to warm up slightly before placing it in a pre-heated oven. This will provide the safest transition for your Pyrex dish from the fridge to the oven.
How to Cook Frozen Pie Crusts in Pyrex Dishes
The most common reason to move a cold Pyrex dish from the fridge to the oven is when making pie crusts. To protect your Pyrex however, the transition from the fridge to the bench is very important.
Do not be tempted to place your Pyrex dish straight from the fridge or freezer to the oven as it could easily shatter. If you want to cook a pie crust which has cooled in the fridge, place it in a short time on your bench to warm up slightly. This will only usually take 15-30 minutes. Pre-heat the oven while you allow the dish to come up closer to room temperature before placing your Pyrex in the oven.
How to Reheat Lasagna in Pyrex in the Oven
Lasagna is a meal that is great to make in a double batch. You can make your lasagna directly in the Pyrex dish and freeze it uncooked. Make sure the lasagna mix is cool before placing in the freezer. Label it with the name and date.
To reheat a frozen lasagna, take it out and place it in your fridge 24 hours before you want to cook and serve it. Place it on the bench for a short period of time (30 mins approximately) to allow it to come closer to room temperature. It can then be placed in a pre-heated oven to cook.
