Can You Put Pyrex on a Gas Grill?

Grilling is one of the most popular outdoor activities for many people worldwide, especially during summer. It is a great way to spend time with family and friends while enjoying delicious meals. However, with so many different types of cookware available, it can be challenging to know which ones are safe to use on a gas grill. In this article, we will look at whether it is safe to put Pyrex on a gas grill.

What is Pyrex?

Pyrex is a brand of cookware that was founded in 1915 by Corning Inc. It is made of high-quality tempered glass that can withstand temperature changes without cracking or breaking. Pyrex has become one of the most popular cookware brands globally due to its affordability and durability.

Pyrex comes in different forms depending on the intended use; some have a metal base or aluminum exteriors to make them more suitable for use in the oven and cooking stove top. Pyrex containers come in several shapes including baking dishes, casserole dishes, mixing bowls, measuring cups, and even storage containers.

The use of Pyrex cookware has become highly prevalent amongst cooking enthusiasts due to its transparency, making it easier to monitor cooking progress while under heat.

What Happens When You Put Pyrex on a Gas Grill?

The question regarding whether you can use Pyrex on a gas grill generates mixed opinions from people. Some assume that putting Pyrex cookware disks on a gas grill to heat up food can lead to the dishes exploding or shattering due to high temperatures.

In contrast, others assert that you can use Pyrex on gas grills worry-free as long as you adhere to recommended temperature guidelines and handle the dishes properly.

The truth is, Pyrex is not intended for direct exposure to high heat flames, and when exposed to such temperatures, the cookware may shatter due to thermal shock. Given that gas grills get very hot, it puts Pyrex dishes at a heightened risk of shattering or cracking when placed over the flames.

For this reason, it’s not advisable to put Pyrex on a gas grill directly as it can break or explode due to high temperatures. Doing this can cause harm and pose potential safety risks. It is essential to avoid exposing Pyrex dishes to sudden temperature fluctuations from extreme heat exposure as this can lead to thermal shock and breakage.

Alternative Options to Using Pyrex on Gas Grills

While it isn’t safe to use Pyrex on gas grills directly, there are alternative ways of cooking with your glass cookware outdoors.

  • Double-Wrapped Aluminum Foil: One safe alternative is using aluminum foil instead of Pyrex while cooking on your gas grill. You can place your food in an oven-safe dish (preferably a disposable option) and wrap the dish tightly with aluminum foil before placing it on a preheated gas grill. The aluminum wrapper helps prevent direct exposure of the cookware to high flames while protecting what’s beneath.

Preparing Your Gas Grill

Before you start using your gas grill for cooking, it’s important first to prepare the equipment for safe cooking. Here are some vital steps for preparing your gas grill:

  • Scrub the Grill Grate: Use a durable wire brush tool and soapy water to scrub down your grill grate until it’s free of any debris remaining from previous use.
  • Clean Your Cooking Surface: Use a damp cloth or sponge and mild dish soap to clean the surface where you’ll be placing your cookware.
  • Adjust Temperature: Turn down the heat temperature to medium to avoid overheating, especially for long cooking durations. This steers clear of exposing your cookware to extreme temperatures that may cause thermal shock and breakage.

Tips for Grilling with Cookware

Here are some essential guidelines to follow while using cookware on a gas grill:

  • Start with a low temperature: Start by preheating your cooking equipment on a lowered heat setting gradually until you get to the required cooking temperature. This helps prevent sudden thermal shifts that could cause breakage or even injure the pit master.
  • Avoid Placing Cold Food on Hot Cookware: Allow food items or dishes to cool before putting them on pre-heated cookware. You can also opt for ceramic or cast iron as alternatives since these materials can bear high temperatures better than glass cookware.
  • Do Not Place Hot Cookware on Cool Surfaces: Never place hot cookware on cool surfaces, as this can lead to breakage and damage.

Proper Maintenance for Your Cookware and Grills

To ensure that your grill and cookware last long, proper maintenance is necessary. Here are some tips to help keep them in good condition:

  • Clean Your Grill After Every Use: Clean your entire gas grill thoroughly every time you use it, so it remains sanitary and free of build-ups that could ignite fires
  • Avoid Glass Cleaners And Abrasive Scrubbers:Cleaning the Pyrex dishes should be done with plastic sponges or brushes to avoid scratching and easily damaging the material.

Specific Guidelines for Different Pyrex Products

The recommended guidelines when using Pyrex products on a gas grill are:

  • Baking dishes, Mixing bowls, and Casserole Dishes: These types of cookware can be used on a gas grill provided that they are first preheated in an oven before use. This helps eliminate any potential thermal shocks when placed in direct contact with heat flames.
  • Storage Containers and Measuring Cups: These should not be put on direct heat as it could cave in due to lack of structural strength as other Pyrex baking dishes might have.


Here are some frequently asked questions regarding this topic:

  • Can aluminum foil be used instead of Pyrex?
  • Answer: Yes, you can use aluminum foil instead of Pyrex while cooking on your gas grill.

  • Can I put Pyrex in a hot oven after heating it up in a cold refrigerator?
  • Answer: Doing so will cause extreme temperature fluctuations, leading to potential thermal shock. It’s recommended to allow sea level temperature exposure until cookware has adapted before subjecting it to extreme temperature shifts caused by using hot ovens or refrigerators.

Final Thoughts

The safe use of cookware while grilling is crucial. Always prioritize safety by handling any cookware with care to avoid injury. If you want to use Pyrex for outdoor cooking, opting for double-wrapped aluminum foil or ceramic materials is advisable since they are better suited. Remember always to adhere to recommended guidelines or best practices.


Grilling with Pyrex cookware on your gas grill is not advisable, as the heat generated may likely cause the Pyrex to crack or explode due to high temperatures. Always prioritize safety by using alternatives such as ceramic cookware or double-wrapped aluminum foil. Ensure that you use and maintain your grill correctly, always follow standard guidelines, temperature requirements, and never subject your cookware to extreme temperature shifts.
