And the answer is yes, CorningWare cookware is oven-safe! You can conveniently use it in various oven types, such as conventional and convection ovens.

Continue reading to find out how CorningWare does in high heat.
We’ll also provide tips on how to use this popular cookware brand when cooking in your oven!
Key Takeaways
- CorningWare is safe to put in the oven at temperatures up to 450 degrees Fahrenheit, but some products may be able to handle higher temperatures depending on the material they use.
- Most CorningWare cookware and bakeware are suitable for different oven types, including conventional, convection, toaster, and microwave ovens. Specific precautions are needed for convection ovens and broilers.
- Following precautions like consulting the manufacturer’s instructions to determine your CorningWare dish’s maximum temperature limit is best for safety.
Up to What Temperature Is CoringWare Oven-Safe?
Now that we’ve established that CorningWare can indeed go in the oven, you may be wondering about its maximum temperature.
In general, CorningWare is oven-safe at up to 450 degrees Fahrenheit.
But take note that some of its products may have a lower or higher maximum temperature, depending on the material they’re made from.
Maximum Temperature of Different Types of CorningWare Products
Type | Material | Properties | Maximum Temperature |
---|---|---|---|
Pyroceram | Unique glass-ceramic | Heat- and thermal shock-resistant | 450°F to 500°F |
Stoneware | Ceramic | Heat-resistant | 350°F to 400°F |
As you can see above, CorningWare bakeware and cookware made with Pyroceram can handle higher temperatures than its stoneware.
Why? Pyroceram is a proprietary glass-ceramic material designed to have very low thermal expansion and high thermal shock resistance.
This means it can be exposed to sudden temperature changes in the oven without cracking or shattering.
On the other hand, while CorningWare stoneware can still withstand high heat well, it’s slightly more susceptible to thermal shock than Pyroceram.
So it may crack more easily when exposed to uneven heating or rapid temperature changes.

Pro Tip: Most CorningWare dishes have glass lids that are oven-safe, but they can only be used at a maximum of 350°F. So remove the lid of your CorningWare dish before putting it in the oven if your recipe calls for high heat.
Can You Use CorningWare in All Types of Ovens?
CorningWare is very versatile, so it can be used in most types of home ovens.
Here are some facts and tips for using its cookware based on the oven type you have:
Conventional Oven

Standard conventional ovens are one of the best options for using CorningWare, as temperatures tend to be more consistent throughout compared to other oven types.
As such, you can use it for baking and roasting without worry!
Pro Tip: Place CorningWare dishes on an oven rack away from the direct heat at the bottom or back of the oven.
Convection Oven
The increased air circulation in convection ovens can sometimes cause “hot spots” or areas where the heat is stronger.
So it’s best to be extra careful when using CorningWare dishes in this type of oven.
Pro Tip: Keep your CorningWare dish or pan a few inches above the oven floor or away from the sides when it’s in convection mode.
Broiler in the Oven

Broilers usually function at very high temperatures ranging from 500°F to 550°F.
So not all oven-safe CorningWare dishes are broiler-safe. You’ll have to check the manufacturer’s instructions for use to see if the specific model you bought can be used in your broiler.
Pro Tip: If you want a broiler-safe CorningWare product, get the CorningWare Classic Square Casserole.
Aside from being extremely resilient and capable of withstanding high heat, its 1.5-liter capacity also makes it ideal for serving large groups.
Toaster Oven

CorningWare is also suitable for toaster ovens.
You can use it for toasting, baking, or reheating food, provided the toaster oven is big enough to accommodate the dish.
Pro Tip: Make sure that your CorningWare doesn't touch any of the inside surfaces to avoid any potential damage.
Microwave Oven

It’s generally safe to use CorningWare products in the microwave to reheat food or even cook quick meals.
But you’ll have to follow a few precautions for guaranteed safety.
Pro Tips:
- Check to see if your CorningWare dish has a “microwave-safe” label, especially if it’s an old product.
- Use low to medium heat levels and check the food frequently to prevent any liquids in it from boiling over.
- Avoid using cracked or chipped CorningWare dishes in the microwave to prevent further damage and safety issues.
Tips for Using CorningWare in the Oven
While CorningWare is safe in the oven, it’s still a good idea to follow safety guidelines.
Doing this will help keep your favorite CorningWare products in tip-top condition, prevent accidents or injuries, and ensure a secure, enjoyable cooking experience!
Check the Temperature Limit
Always check the bottom of the CorningWare dish, the booklet of instructions for use, or the box it comes in for its temperature limit.
Don't go over the limit so your dish won’t get damaged.
Start Low and Increase Later

Start baking at a lower oven temperature if your recipe allows.
This gives your CorningWare time to adjust to the heat gradually, preventing thermal shock that can cause your dish to break.
You can always increase the temperature later in the cooking process.
Be Careful Removing From the Oven
When removing hot CorningWare from the oven, be very careful!
Use oven mitts to protect your hands from the heat. Set the dish on a heat-safe surface and let it cool slowly before moving. No need to rush.

Benefits of Using CorningWare in the Oven
There are several benefits to using this brand in the oven!
Here are some reasons why it’s ideal for all your cooking and baking needs:
Even Heat Distribution
The Pyroceram and ceramic materials used in CorningWare products allow them to handle and retain high heat, ensuring that the heat spreads equally throughout the dish.
This results in evenly cooked food without burnt or undercooked areas. So it provides a consistent texture and taste.
Additionally, it makes CorningWare suitable for recipes like the following:
- Casseroles
- Stews
- Soups
- Roasts
- Lasagna
- Mac and cheese
- Meatloaf
- Baked chicken
- Cobbler
- Pies
Easy Transition From Oven to Table
Another benefit of using CorningWare is its ability to seamlessly transition from the oven to your table.
Because of its elegant and timeless design, these dishes can be used for serving your freshly prepared meals.
There’s no need to transfer the food to a serving dish, so you’ll save both time and effort!
Durability and Long Life Span
CorningWare dishes are known for their durability and long life span. They are made to withstand high heat and resist thermal shock, which contributes to their lasting quality.
With proper care, CorningWare cookware can last you many years, making it a valuable investment for your kitchen.

Frequently Asked Questions
Is Vintage Corningware Oven-Safe?
Made from incredibly durable material, CorningWare cookware can last for decades and be passed down from one generation to another.
Luckily, most vintage CorningWare products are oven-safe. These include dishes with the company’s signature blue cornflower design.
That said, there are some concerns about using vintage CorningWare in the oven, which are as follows:
- Some old CorningWare products may be less capable of handling high heat than others. So be sure to check the bottom of the dish to see if it’s oven-safe before using it.
If you bought it from a thrift store or an online shop, you can also ask the seller about whether it can be safely used in the oven.

This is because the glaze or paint used in older types of cookware previously contained lead.
Now the oven’s high heat can cause lead from a dish to leach into your food, which can pose serious health risks.
While the levels of lead in vintage CorningWare dishes may vary, it’s best to err on the safe side. You can determine if your dish has alarmingly high levels of lead by using lead-testing kits.
Is CorningWare French White Oven-Safe?
Yes, most products from the classic CorningWare French White collection are oven-safe since they are made with the original Pyroceram material.
For instance, all the pieces in the Corningware French White 6-Piece Bakeware Set can handle high temperatures even beyond 500°F!
Can I Use My CorningWare on the Stovetop Directly?
While CorningWare is typically oven-safe, manufacturers don’t recommend using it directly on the stovetop, especially the stoneware type of CorningWare.
The direct heat may cause the dish to shatter.
Use CorningWare in the Oven at the Right Temperature To Enjoy Delicious Meals!
