Many of us are used to the convenience of using microwave-safe containers, but what about when it comes to putting them in the oven? If you’re wondering whether or not microwave safe bowls can be used in the oven, you’re not alone.
In this article, we’ll explore the safety concerns around putting microwave safe containers in the oven and provide helpful tips for using alternative types of containers.
Can microwave safe bowls go in the oven?
In many cases, microwave-safe bowls should not be used in the oven.
While they are designed to withstand the heat generated by microwaves, they may not be suitable for the higher temperatures found in ovens.
Microwave-safe bowls are typically made of materials like glass, ceramic, or certain types of plastic that are safe for use in the microwave.
However, these materials can be vulnerable to thermal shock, which is the rapid expansion or contraction caused by extreme temperature changes.
Placing a microwave-safe bowl in the oven could lead to cracking, shattering, or other damage, posing a safety risk and potentially ruining your dish.
How to tell if a microwave safe container is also oven safe
1. Check the label
To tell if a container is microwave safe, look for labels on the back of the dish. Most dishes will have labels that state if they are microwave or oven-safe.
If there are no labels, you can check with the manufacturer to see if the dish is microwave safe and oven safe.
What you want to do is look for the oven symbol. If you see this symbol, then chances are your container is oven safe as well.
The symbol can be described as a square in the shape of an oven with a row of button dials on top and some vertical wavy lines underneath.
Sometimes, these vertical wavy lines will be replaced with the temperature limits such as “500 degrees F”
Sometimes it will even say that it’s oven safe.
2. Inspect the container
You can determine if a microwave safe container is oven safe by checking the back of the container.
If the container does not state that it is oven safe, then it is most likely oven-safe. If you can’t determine if the container is oven-safe, then you should contact your supplier.
The oven safe symbol can also be found imprinted or stained right into the container itself as well.
You can usually find these at the bottom of your container out of sight. But if you turn your container upside down and look around, you might find it.
3. Test the container
If you want to be a little risky, you can test to see whether or not your microwave safe container is also oven safe.
Keep in mind, this may slightly damaged your container if you attempt to do so.
You can place the container into the oven and preheat it up for about 3 to 5 minutes at around 350 degrees Fahrenheit. That should be enough time to tell whether or not your container is oven safe while not destroying your container.
Once it’s out, put on some heat-proof oven mitts, and try to bend the container slightly to see if it is distorting.
Try not to bend too much because if it’s not oven safe, you might end up permanently distorting it.
You just want to see if it become mold-able at this warm temperature.
If it’s not warping, then chances are, you have an oven safe container. However, this shouldn’t be the only Factor you use to determine whether or not your container is oven safe.
I would recommend testing it a few more times leaving it in the oven for a bit longer than before.
If there is no distortion or changes that you can visually see, then chances are it is oven safe.
4. Use caution with plastic containers
Before using any plastic container in the microwave, it is important to check that it is safe to do so.
Some plastics are not meant to be in the oven and can leach harmful chemicals into food. Single-use plastics, like yogurt containers, should not be used in the oven.
Baking silicone is generally safe to use, but it is best to check the label to be sure.
There are also some plastic containers that are specifically made to be baked in the oven. These are usually clearly marked.
Reusable or biodegradable containers are a safer option than disposable plastic ones.
When using any kind of container in the oven, avoid melting or leaching chemicals into food by not overheating it.
5. Use caution with foam containers
You should never put foam containers in a microwave. The highest temperature that foam can ever reach without melting 180 and 190 degrees Fahrenheit.
It’s not only a poor choice of material to put in the oven, it’s also extremely dangerous.
If you end up melting foam, it will likely give off black smoke and fumes breaking polystyrene down to styrene. These fumes produced are toxic to people and animals.
6. Use caution with glass containers
Surprisingly, not all glass containers are oven safe. Some glass containers can withstand really high temperatures more than others.
For example, there’s such a thing called tempered glass which is actually glass that is taken back into a furnace and heated well above 1047 degrees Fahrenheit.
As a result, tempered glass can withstand up to 470 degrees Fahrenheit. This is compared to regular glass which can withstand roughly up to 392 degrees Fahrenheit without breaking.
What are microwave safe containers?
Microwave safe containers are containers that have been tested to make sure that they are safe to use in a microwave.
Most microwave safe containers are made with high-density polyehtlene (HDPE) which can withstand temperatures between -40 and 266 degrees Fahrenheit before it melts or breaks.
You can usually tell if a container is microwave safe by looking for a symbol on the bottom or back of the container. If you can’t find a symbol, it’s best to avoid using the container in the microwave.
What are the dangers of putting microwave safe containers in the oven?
- The container may shatter or melt, causing food to be contaminated: Single-use or disposable plastic containers are not recommended for use in microwave ovens as they may melt or leach chemicals into the food. Plastic containers and plates that can be heated in the microwave have passed safety inspection.
- The container may shatter or melt, causing a mess: If you place a non safe microwavable container in a microwave and it melts, your food spill all over and create a huge mess. No one likes cleaning up melted plastic with food all over it.
- The mess caused may damage the oven: Not only that melted plastic and food everywhere will cause a mess, you may also end up damaging your microwave oven as well. The food may end up getting stuck in between the corners and cracks and one day potentially housing rust. It can also see right into the turning gears underneath the turning table And cause clogs.
- Non-oven safe containers may release harmful fumes: When cooking in the oven, it is important to use only containers that are marked as oven-safe. Containers that are not meant to withstand high temperatures can melt and release harmful fumes. These fumes can be harmful if inhaled, so it is important to be aware of the dangers of using non-oven safe containers. Because of the potential for injury to yourself and others, you should always check with the manufacturer before using an unfamiliar container in a microwave.
- The container may catch on fire: Putting microwave safe containers in the oven can be dangerous because they can catch on fire. This is especially true if you let your microwave unattended while microwaving a non microwave safe container. After several minutes of cooking, a fire may erupt. Always check the label to make sure the container is oven-ready before putting it in the microwave. If you’re unsure, contact your supplier.
What are some alternatives to using microwave safe containers in the oven?
- Use an oven-safe container: You can use an oven-safe container as an alternative to using microwave safe containers in the oven. Glass, Pyrex, and silicone containers are all great options for using in the oven. Just be sure to check the temperature range printed on the label of the package or on the bottom of the container to ensure it is safe for use in the oven. If you can’t determine if a container is oven-safe, contact your supplier.
- Use a glass container: If you’re looking for an alternative to microwave safe containers, glass is a great option. Glass is oven-safe and microwave safe, so it can be used for reheating or boiling water. Just make sure you’re using the right cookware for the job. Pyrex is a type of glass that’s often used for food storage and it can withstand high temperatures. Glass containers are also durable and easy to clean.
- Use an aluminum container: If you don’t have a microwave safe container and need to use the oven, aluminum foil is a good alternative. To use, first wrap the food in foil and then place in a preheated oven at 350 degrees Fahrenheit. Make sure there is no plastic on the food or on the foil so it doesn’t melt and cause fires. Aluminum is recyclable, but not the safest option for takeout containers.
- Use a cast iron container: Cast iron is a great alternative to using microwave safe containers in the oven. They are durable and can withstand high temperatures, plus they are easy to clean. You can say that cast iron is literally designed and built for ovens and open flames.
- Use a Dutch oven: A Dutch oven can be used as an alternative to using microwave safe containers in the oven. Dutch ovens are made of cast iron and are oven and microwave safe. Dutch ovens have a long history of being used in the oven hence the name. This makes them a good choice for cooking food in the oven or microwaving it without risk of damage.
- Use a metal container: Now, there are way more metals out there then we can count, and there are several different ones used to make containers that are oven safe. Different metals have different abilities when it comes to heat. However, generally speaking, metal containers are great conductors of heat. They are highly efficient in evenly spreading heat all throughout itself. There are also very easy to clean. And they’re extremely durable. It would take a lot of heat the damage most metal containers.
- Use a ceramic container: A ceramic container can be used as an alternative to a microwave safe container in the oven. Ceramic containers are durable and easy to clean, making them a good option for cooking food in the oven.
