Key Takeaways: Most plates should only be used in an oven when they are clearly labeled oven-safe. Microwave-safe does not mean oven-safe, and disposable plates should not be placed in ovens unless the product packaging or supplier documentation confirms the temperature and time limits. Oven-rated ceramic, tempered glass, cast iron, stainless steel, silicone bakeware and aluminum trays may be suitable for certain oven uses, while plastic, Styrofoam, most paper plates, wooden plates and unlabeled disposable plates should be avoided. Bagasse plates are best treated as foodservice serving and takeaway tableware unless a specific product is clearly rated for oven use. Foodservice buyers should confirm labels, specifications and sample performance before bulk ordering.
This article can help you purchase the right oven-safe dishes for your food business. So, let’s look at what to consider before putting plates in the oven, how to choose oven-safe dishes, the risks of not using oven-safe kitchenware, and more.
Before we go into detail about which plates and dishes you can and can’t use in the oven, we should cover the basics. These are some things to consider before sticking a plate or dish in the oven:
First thing’s first: what is the dish made of? Is it labeled as oven-safe? Certain materials, which we’ll cover later on in the blog, are usually safe. On the other hand, plates or dishes made from materials like wood aren’t oven safe.
The material isn’t the only thing you should consider. Even if it’s labeled as an oven-safe plate, it has a maximum setting. So, your dish may not be able to withstand high temperature settings in your oven. Going over this setting can cause the dish to shatter or break.
Did you know that a sudden and high change in temperature can end up damaging your plates? Yes, even if it’s made from oven-safe materials, putting a cold dish in a hot oven or a hot dish on a cold counter can make it crack.
Even if it’s oven-safe, the size of your dish and oven matter! When you place a plate in the toaster oven, there needs to be enough room for the air to circulate. If it’s too big or the oven is too small, your dish can warp or the food may not cook properly.
Don’t just choose a dish because the material is typically oven safe. That’s because some plates and dishes come with non-stick coatings that aren’t formulated for oven use. At high temperatures, these coatings break down and release harmful fumes.
Lastly, keep a check on the condition of your dishes. They should be intact and without any defects like cracks or chipped edges. The smallest imperfection gets worse because of high temperatures, causing your plate to break.
When a plate isn’t oven safe and you put it in the oven, it could end up cracking, shattering, melting, or warping. Of course, what happens depends on the material, but you end up with a big mess in the oven.
You’ll need to clean up broken glass or melted plastic from the oven, which can take a lot of time and slow down operations.
That is, if you can clean it up. In some cases, the materials end up damaging your oven and you’ll need to replace it. Similarly, if the dish had decorations, glazes, or non-stick coatings that aren’t oven-safe, they degrade and release harmful fumes.
They could contaminate the food and are dangerous when inhaled. And the most dangerous: putting a non-oven-safe dish in an oven could cause a fire hazard, especially if it’s made from compostable materials.
Besides checking the material that your plates or dishes are made of, there are a few other ways to know if your kitchenware is safe.
Oven-safe dishes are labeled at the bottom with an oven symbol and terms saying ‘oven-safe’ or ‘heat-resistant’.
Most dishes come with instructions in the manual or on the packaging, detailing whether it’s oven-safe.
Another option is to test the plate in the oven at a low temperature. Keep it in the oven at about 250°F for 15 minutes. If the plate is intact and doesn’t show signs of cracking or warping, it’s oven-safe.
Most ceramic plates and dishes are heat resistant and can take on high temperatures, so they’re suitable for oven use.
Metal-based cookware like cast iron and stainless steel pans are generally oven-safe. Thanks to their quick heat transmission, your food cooks quickly.
Silicone cookware like muffin tins, baking trays, and mats can withstand both high and low temperatures without melting or warping.
Notice how we said pyrex glass? That’s because not all glass is oven-safe. Meanwhile, pyrex glass is built to withstand high temperatures.
Aluminum foil is disposable and commonly used as plates, food packaging and other products. It can be used in ovens.
Some bioplastic trays are safe in some ovens, but should be checked for heat resistance before use.
Clearly labeled as oven safe or heat resistant, otherwise these materials may burn.
You should never cook or bake in a plastic plate or dish because they can’t withstand high temperatures. If you put them in the oven, they’ll melt and/or release harmful fumes.
Some specific molded fiber products may support limited low-temperature warming when clearly labeled by the supplier. Always confirm the exact temperature, time limit and usage instructions before oven use. Bagasse plates and containers are also oven-safe if you’re heating food at temperatures of up to 250°F.
Unless you’re using specific types of paper that’s designed for oven-use, don’t use paper plates or dishes in the oven. Parchment paper is a good example of heat-resistant paper, while wax paper or plain paper pose fire hazards.
You can’t put styrofoam cutlery in the oven because of its low temperature limits. Exposure to high temperatures releases harmful chemicals and fumes that can affect your health.
Microwave-safe and oven-safe are different claims.
A microwave heats food mainly through microwave energy, while an oven heats the air and surfaces around the plate. Oven heat can expose the plate to higher and more direct thermal stress.
A plate that works in a microwave may still be unsafe in an oven. For example, some paper, fiber or plastic-coated products may tolerate short microwave reheating but should not be used in conventional ovens.
Foodservice buyers should never treat these terms as interchangeable:
Microwave-safe: suitable for specific microwave use conditions
Oven-safe: suitable for specific oven temperature and time conditions
Heat-resistant: not a complete use instruction by itself
Hot food suitable: able to hold hot food, not necessarily oven-safe
Always confirm the specific product use conditions before heating.
Even if you’re using oven-safe materials, there are a few best practices to implement.
1. Make sure you preheat the oven to your desired temperature before putting your plates or dishes inside.
2. Keep your dish on top of a baking sheet in your oven so that it catches any spills.
3. Use oven mitts and heat-resistant utensils to handle or remove the plate.
4. If you’re using a dish or plate in the oven for the first time, keep an eye on the oven to check for signs of warping and cracking.
5. After taking the plate or dish out of the oven, let it cool on the counter instead of putting it in the fridge or freezer.
6. Oven-safe dishes aren’t suitable for exposure to very high temperatures (like from grilling or broiling) or direct flame (on a stovetop).
1. Does microwave-safe mean oven-safe?
No! If a plate or dish is labelled as microwave safe, you can’t assume that it’s oven safe as well. If you want microwave and oven-safe dishes for your food business, check the bottom for both microwave-safe and oven-safe symbols.
2. What if my oven-safe dish cracks in the oven?
If your oven-safe dish cracks in the oven, turn off the oven immediately and let the plate cool before removing it. Dispose of the plate and clean your oven thoroughly before using it again.
3. Can I put disposable plates in the oven?
Most disposable plates should not be placed in an oven unless the product packaging or supplier documentation clearly says they are oven-safe.
4. What’s the temperature limit for oven-safe plates?
Usually, oven-safe plates can withstand temperatures as high as 350°F to 400°F, but you should still check the manual for specific limits.
When you’re choosing plates and dishes to use in the oven, you have to consider materials, temperature limits, and whether the dish is intact. Before you put them in the oven, make sure that dishes are marked ‘oven-safe.’ Otherwise, you’ll deal with problems like cracking, melting, and warping dishes. Some dishes can also release toxic fumes, catch fire, and render your oven useless.
Usually, kitchenware made from ceramic, cast iron, stainless steel, or pyrex glass is oven-safe, but plastic, styrofoam, paper, and wood aren’t. Even if you’re using oven-safe kitchenware, make sure to preheat your oven, use oven mitts when handling dishes, and letting them cool at room temperature.
