Over my 10 years as a chef, I’ve made my fair share of mistakes with oven safe cookware. I’ve seen glass dishes crack under heat, non-stick pans warp in the oven, and even handles melt because I didn’t realize they weren’t heat-resistant. These weren’t just frustrating moments—they were valuable lessons that taught me how to use cookware safely and avoid costly, messy disasters.
I know how easy it is to assume your cookware is ready for the oven, only to find out too late that something’s gone wrong. That’s why I’ve put together this guide to help you avoid the mistakes I’ve made throughout my career. From skipping the preheating step to misjudging temperature limits, these are real problems I’ve encountered, and I’m sharing what I’ve learned so you can cook confidently and safely.
Let’s dive into the most common mistakes people make when using oven safe cookware—and how to steer clear of them! 😊
Mistake 1: Assuming All Cookware Is Fully Oven Safe
Just because cookware is labeled as “oven-safe” doesn’t mean every part of it can handle high temperatures. I learned this the hard way when I used a pan with rubberized handles for roasting. While the pan itself was fine, the handles melted slightly, leaving a burnt smell in the kitchen.
Some cookware bases, like stainless steel or cast iron, may be oven-safe, but the attached parts—like plastic handles, glass lids, or rubber seals—might not withstand heat. Always double-check every component of the cookware before putting it in the oven. If in doubt, remove detachable parts or use alternatives like metal handles or heat-safe lids.

Mistake 2: Ignoring Temperature Limits
One of the most common mistakes I’ve seen (and made!) is pushing cookware beyond its temperature limits. Oven-safe doesn’t mean it can handle every heat level. For example, tempered glass can crack if exposed to temperatures above 425°F, while non-stick coatings might degrade around 400°F.
To avoid damaging your cookware—or worse, releasing harmful fumes—always check the manufacturer’s recommended temperature range. If that information isn’t available, play it safe by sticking to lower oven temperatures. I personally test new cookware at 300°F to see how it holds up before trying higher temperatures.
Mistake 3: Using Cookware With Cracks or Chips
If your ceramic or glass cookware has visible cracks or chips, it’s time to retire it from oven use. Damaged cookware is more likely to break under heat, which can lead to dangerous situations. I once ignored a small chip in a ceramic baking dish, only to have it split in the oven while baking a pie. Cleaning molten filling off the oven was a nightmare!
Cracks weaken the material’s ability to withstand heat and can cause uneven expansion, leading to sudden breakage. Always inspect your cookware before use, and if you notice any damage, consider replacing it. It’s better to be safe than risk a kitchen disaster.

Mistake 4: Sudden Temperature Changes (Thermal Shock)
Thermal shock occurs when cookware faces sudden temperature changes. It is a common reason glass and ceramic dishes break. For example, placing hot cookware on a cold countertop can cause cracks. Pouring cold water into a hot dish can also make it shatter instantly.
I’ve made this mistake before, and trust me—it’s not worth the cleanup! To avoid thermal shock, always let cookware cool gradually. Use heat-resistant trivets or towels to protect surfaces and allow hot dishes to sit for a few minutes before handling them.

Mistake 5: Using Non-Stick Cookware at High Temperatures
Non-stick cookware is a staple in many kitchens, but it’s not built for extreme heat. Most non-stick coatings start breaking down around 400°F, releasing fumes that can be harmful to your health. I once baked cookies on a non-stick pan without checking the temperature guidelines and ended up with a warped pan and a funny smell in the kitchen.
To keep your non-stick cookware in good shape, reserve it for stovetop use or oven recipes that require lower heat. Always check the manufacturer’s instructions to see if it’s safe for oven use and, if so, what the maximum temperature is.
Mistake 6: Forgetting to Preheat the Oven
One common mistake I’ve seen (and made in my early years) is skipping the preheating step. Placing cookware in a cold oven and letting it heat along with the oven may seem harmless, but it can cause two major issues.
First, it leads to uneven cooking. Your food may take longer to cook or cook unevenly because the temperature rises gradually rather than starting at the right level. I once baked cookies without preheating, and while the bottoms browned perfectly, the tops stayed pale and undercooked.
Second, it can stress the cookware, especially glass or ceramic dishes. As the oven heats up, the gradual temperature change can cause the material to expand unevenly, leading to cracks or warping over time. This is particularly risky for glass bakeware, which is more sensitive to temperature fluctuations.
Tip: Always preheat your oven to the correct temperature before placing any cookware inside. While it may take a few extra minutes, this simple step ensures your food cooks evenly and protects your cookware from unnecessary stress. I’ve made it a habit to preheat the oven as the first step in any recipe—it saves time and guarantees better results!

FAQs
Can I use frozen glass cookware directly in the oven?
No, placing frozen glass cookware directly in a hot oven can cause it to shatter due to thermal shock. Always let glass cookware thaw to room temperature before using it in the oven.
Is it safe to use aluminum foil with oven safe cookware?
Yes, aluminum foil is safe to use with oven safe cookware. However, avoid wrapping non-stick cookware, as it can trap heat and damage the coating.
What’s the best way to clean oven safe cookware after use?
Let the cookware cool completely before washing. Use warm water, mild soap, and a non-abrasive sponge to avoid damaging the surface.
Can I use parchment paper with oven safe cookware?
Yes, parchment paper is safe to use as long as you stay below its maximum heat limit (usually 420°F–450°F).
How do I know if my cookware is broiler-safe?
Broiler-safe cookware can withstand very high heat without warping or breaking. Check the manufacturer’s instructions or ensure it’s made from materials like stainless steel or cast iron without any plastic parts.
Can I place hot cookware directly into the fridge?
No, placing hot cookware into the fridge can cause thermal shock, damaging both the cookware and your fridge. Let it cool completely before refrigeration.
