Have you ever been tempted to heat up leftovers in a silicone container or quickly defrost meat using a silicone bag? It’s easy to see the perks of using silicone for cooking and storage – it’s durable, non-stick, and doesn’t release harmful chemicals into your food.

But can you actually put silicone in the microwave? Before breaking out that silicone bakeware or storage container, find out if it’s microwave-safe.

In my latest blog post, I dive into the world of microwaving silicone to provide you with all the answers. From common misconceptions to tips for safe use, I cover it all. So whether you’re looking to reheat leftovers or defrost frozen food, this article will help guide your microwave usage with silicone products.

Can You Microwave Silicone?

The FDA has approved silicone bakeware and cookware as safe for use in cooking and baking. It has a high heat resistance and can withstand temperatures of up to 500 degrees Fahrenheit. So go ahead and bake those cookies in your silicone baking mold- they’ll come out just as tasty as they would on a metal pan.

However, while silicone is heat resistant, not all silicone products are safe to use in the microwave. Some silicone products that are not food-grade or not made specifically for the microwave can release harmful chemicals into your food when heated.

To ensure that your silicone product is safe to use in the microwave, the first step is to check the manufacturer’s instructions. If the package doesn’t say that the product is microwave-safe, it’s best to err on the side of caution and not use it in the microwave.

In addition, even if a product is labeled as microwave-safe, it’s important to test it before using it to make sure that it doesn’t release any harmful chemicals into your food. I’ll show you how to do that in the next section.

What Is Silicone?

Silicone is a synthetic material that can be used for various purposes, including cooking and baking. It’s made up of silicon, oxygen, and other elements like carbon and hydrogen. Because it can withstand high temperatures and has a very low water absorption rate, silicone is ideal for use in a wide range of products, including:

  • Cooking utensils and bakeware
  • Grooming products like shampoo, conditioner, and hair styling products
  • Medical devices like tubing and catheters
  • O-rings and gaskets
  • Sealants
  • Windshield wipers
  • And much more!

Chances are good that you have at least one silicone product in your home right now. So next time you reach for your favorite spatula or take a swig from your water bottle, think about all the places this incredible polymer can be found.

How to Test If a Silicone Product Is Microwave Safe

Although the FDA has approved silicone as safe for use in the microwave, not all silicone products are created equal. Some manufacturers add fillers to their silicone products to cut costs.

These filler chemicals can make their way into food when the silicone product is used in the microwave, which is why it’s so important to test for them before using a silicone product in the microwave.

The best way to test if a silicone product is safe to use in the microwave is to pinch and twist a flat surface of it. If any white shows through, that means there are chemical fillers in the silicone. The product is not safe to use in the microwave and should not come into contact with food.

If you don’t see any white fillers, the product is safe to use in the microwave. Just be sure to follow the manufacturer’s instructions for microwaving to avoid damaging the product.

The Pros and Cons of Using Silicone Bakeware

We all want to make life in the kitchen as easy as possible, so it’s no surprise that silicone bakeware has become such a popular choice in recent years. But what are the pros and cons of using silicone bakeware? Here’s a quick rundown to help you decide if silicone is the right material for your needs.


Silicone Is Easy To use

One of the main reasons people choose silicone bakeware is because it’s so easy to use. Simply pop your food out of the mold when it’s done cooking and give it a quick wash – it doesn’t get much simpler than that!

Silicone Is Non-Stick Bakeware

Another big advantage of silicone bakeware is that it’s non-stick This means less mess and less wasted food, which is always a good thing. Plus, since there’s no need for butter or oil, you can cut down on fat and calories too!

Silicone Bakeware Saves Space

If you’re short on storage space, silicone bakeware is a great choice. Unlike metal or glass bakeware, it can be easily rolled up or folded to fit into even the tightest spaces, which means it won’t take up half your cupboard like other types of bakeware will. If storage space is tight in your kitchen, silicone molds are worth considering.

The Price Is Relatively Low

Compared to metal or glass bakeware, silicone molds are very affordable. This makes them a great option if you’re on a budget or if you’re just starting out in the kitchen. You can find good quality silicone molds for a fraction of the price of other types of bakeware.


Some Are Very Floppy

Some people find that silicone bakeware is too flimsy and prone to spills. This is especially true of molds with a lot of intricate designs. If you’re clumsy in the kitchen or you’re looking for molds that will hold their shape well, silicone might not be the right material for you.

It Doesn’t Last As Long As Other Options

Depending on how often you use it, silicone bakeware can last anywhere from a few months to a few years. However, it’s not as durable as metal or glass bakeware, so it won’t last as long.

You Can Accidentally Cut The Bakeware

Silicone has a soft, spongy texture that can be easily cut or damaged. Be careful when using sharp knives or other utensils near silicone bakeware, as you could accidentally cut it.

Tips for Using Silicone Bakeware

If you’ve decided that silicone bakeware is right for you, here are a few tips to help you get the most out of it:

Check If Your Silicone Bakeware Is Really Silicone

One of the first things you need to do is make sure your bakeware is made of silicone. There are a few ways to tell if it is silicone or not. First, smell it – if it has a strong plastic smell, it’s not silicone. Second, try to bend it – if it leaves any marks, it’s not silicone. Silicone should be able to revert back to its original shape easily with no marks left behind.

If Your Silicone Bakeware Are Brand New, You Will Want To Clean Them

If your silicone molds are brand new, you will want to clean them before using them. The best way to do this is to wash them in warm soapy water. Rinse them well and let them air dry completely before using them.

As an extra precaution, after washing and drying your molds, you can also cover them with a thin layer of cooking oil. Then preheat your oven to 350 degrees Fahrenheit and bake the molds for about 10 minutes. Take them out of the oven and rinse them with warm water. This will help to get rid of any manufacturing residue that might be on the molds.

Cool Your Silicone Pans After Baking

Once you have baked your goods in the silicone pans, allow them to cool completely before removing them from the pan. This will prevent the silicone from sticking to your food. If you’re in a hurry, you can place the silicone pan on top of a wet towel to help speed up the cooling process.

Surround Your Silicone Mold With Something Sturdy

If you’re using a silicone mold that is particularly floppy, you may want to surround it with something more sturdy. For example, if you’re making a cake, you can place the silicone mold on top of a bowl or pot. This will help to keep the mold in place and prevent it from moving around too much.

Store Silicone Molds In Zip Lock Bags

Once you’ve used your silicone molds, make sure to store them in zip-lock bags. This will help to keep them clean and prevent them from picking up any unwanted smells or flavors.

How Do You Clean Silicone Bakeware?

Just like with any other type of bakeware, you will want to wash your silicone bakeware every time you use it. Here’s how to clean it and get it looking like new again.

Start by wetting down your sponge or brush and adding a little bit of dish soap. Gently scrub the surface of the bakeware with a soapy sponge, paying extra attention to any areas that look especially dirty. If you’re dealing with any stubborn stains, you can try using vinegar or baking soda as a natural abrasive.

Once you’ve given the bakeware a good scrub, rinse it off with warm water and set it aside to air dry. That’s it! Your silicone bakeware should now be clean and ready for its next use.

Alternatives to Microwaving With Silicone

If you’re not a fan of microwaving with silicone, there are a few alternatives that you can try.

1. Glass

Glass is one of the most popular materials for baking and cooking because it is non-reactive, meaning it won’t absorb flavors or odors from food. It’s also easy to clean and withstands high temperatures. However, not all glass is created equal. Be sure to use tempered glass, as it is less likely to break or shatter when exposed to sudden changes in temperature. Pyrex is a good option for tempered glass bakeware.

2. Ceramic

Ceramic cookware is another great alternative to silicone bakeware. Like glass, ceramic is non-reactive and can withstand high temperatures. It’s also oven-safe and microwave-safe, making it a versatile option for cooking and reheating food. However, keep in mind that ceramic cookware can be heavy and require occasional seasoning to keep it in good condition.

3. Stoneware

Stoneware is very similar to ceramic cookware but is typically made from clay that has been fired at a higher temperature, making it more durable and less likely to crack or chip. Stoneware is also oven-safe and microwave-safe, but like ceramic cookware, it can be heavy and difficult to clean if not properly seasoned before use.

4. Microwave-safe Plastic

If you’re looking for a lighter-weight alternative to glass or ceramic bakeware, microwave-safe plastic might be the right material for you. Plastic is much lighter than glass or ceramic and is less likely to break if dropped. However, it’s important to note that not all plastic is microwave-safe. Be sure to check the labeling before using any plastic bakeware in the microwave.


Silicone bakeware and cookware is a popular alternative to metal baking pans. They are non-stick, durable, and can withstand high temperatures.

The FDA has approved silicone for cooking and baking, but not all silicone products are safe to use in the microwave. Before using a silicone product in the microwave, be sure to check the manufacturer’s instructions and test it for safety.
