Are Crock Pot Inserts Microwave Safe?

I hate dirtying a lot of dishes while cooking. This way I get fewer items to clean afterward. 

At times, I just cover up the plate, pot, or pan that has food and store it in the fridge directly.

When I want to eat, I leave the cookware out for some time and then place it back in my microwave or stovetop for reheating. 

I wonder if I can do the same with a crock pot insert?

Are Crock Pot Inserts Microwave Safe? 

Yes, the crock pot inserts are microwave safe till 400° F. 

Microwaves work by heating food through electromagnetic radiation. These rays cannot penetrate through metal. 

This is why you cannot place the whole crockpot inside your microwave. The food will never get heated.

However, you can safely use a microwave to reheat or cook food in a crock pot insert.

Here is a little disclaimer: as you might be aware, “crock pot” is a brand of the slow cooker. If you are using the insert of another slow cooker brand, kindly check the instructions before microwaving the pot insert. 

Things to Remember While Placing the Crock Pot Insert in the Microwave

Let us find out how exactly to place a crock pot inside the microwave.

  • Make sure the insert is clean and dry before you place your food in the microwave.
  • The crock pot insert is microwave safe. However, the lid is not. So you need to cover the insert with a microwave-safe lid or plate. You may also place it uncovered without any lid but I would advise against this. This is because the lid helps to retain heat and prevents the splattering of food. 
  • Some good microwave-safe lids are made up of plastic, silicone, or plain glass (without the metal screw). Plastic is the cheapest option available. If you are planning to use high temperatures, use silicone instead.
  • Silicone is lightweight and adjustable. A glass lid is eco-friendly and does not contain any toxic components like BPA etc. Tempered glass can be bulky and difficult to store. 
  • Do not place anything that has metal inside the microwave. Metals deflect electromagnetic radiations, sending them in erratic directions. This will result in your food not heating up and cooking.  Although rare, the interactions of electromagnetic radiations and metal can also lead to a fire starting in your microwave. 

Caution: the outer part of the crock pot which has a heating element, should never be placed inside along with the insert. 

  • Do place an empty ceramic insert inside the microwave. It may expand and crack after being exposed.
  • Do not use alcohol inside the microwave. It can react with the electromagnetic rays and produce flames.
  • Do not cook food continuously for a prolonged period inside the microwave. It is best to cook in small intervals giving breaks in between. Stop the microwave as soon as you spot sparks, smoke, or fumes. 
  • The inserts can get very hot. You must be careful and wear mitts/ pot holders while removing them from the microwave.
  • Once cooked, the food remains hot for a long time.  You do not have to reheat it for a long time.
  • The inserts are designed for slow cooking in crockpots. They may form hotspots at high temperatures inside the microwave. The trick is to start with low temperatures and increase gradually.

Final Thoughts  

Crockpot inserts are completely safe for use in the microwave. You can use them for reheating or cooking food up to 400F. 

Other than the crock pot brand, you need to read the brand instructions manual of your particular crock pot. 

In general, inserts or dishes made from ceramic or stoneware are safe to go inside the microwave. Anything that has a metal, metal coating, or metal component will not work in the microwave.

Whether you use a crockpot insert or any other brand insert, just remember to remove the lid. This is because all lids have a metallic screw band.  Instead, opt for microwave-safe lids like silicone, tempered glass, or even plastic. 

Always listen to your manufacturer. If the manual says not to use them inside a microwave, do not use them even if the insert is made out of microwave-safe components. Safe cooking!
