Can I Use Slow Cooker Liners in the ​Oven? (Answered)

A slow cooker is a popular kitchen appliance for it makes cooking simple. To avoid mess, we get slow cooker liners in the market. Liners make cooking in a slow cooker more convenient. They not only are easy to use but save your energy and time.

Most slow cooker liner plastic is BPA-free.

Are liners made oven-proof? To know more about slow cooker liners and their use, we recommend reading the article.

Can I use slow cooker liners in the ​oven?

Slow cooker liners cannot go into the oven. They are plastic-made and can resist temperatures up to 400 degrees Fahrenheit. Liners cannot withstand the high temperature of an oven. They are also not meant for a toaster oven, broiler, or refrigerator. Also, liners are for one-time use only.

A slow cooker liner is either nylon or polyester made. During cooking, simply put a liner inside a slow cooker and cook your food inside. Liners are for single-time use only. They can resist temperatures up to 400 degrees Fahrenheit.  

With a slow cooker, the cooking process is easy and is total mess-free. You are not allowed to put liners in the oven, broiler, and refrigerator. However, when marinating inside a liner, you may refrigerate it until cooking. 

Here we have discussed a renowned brand and generic crockpot liners. 

Reynolds liners:

Reynolds offers small and regular-sized slow cooker liners. They are made from heat-resistant nylon and BPA-free. The liners won’t break or leak. You can use high to low or warm settings in your slow cooker when using the liners. They can resist up to 400 degrees Fahrenheit. 

Reynolds recommends it to use only one time. Again, do not put them inside a roaster, oven, or fridge. 

Crockpot plastic liners:

A crockpot uses the same liners as a slow cooker. They are again safe to use, FDA approved, and BPA free.  

Crockpot liners can withstand heat up to 400 degrees Fahrenheit. They are not reusable and not meant for high heat appliances. 

Why shouldn’t you use slow cooker liners in the ​oven?

A slow cooker liner is not suitable for oven, or toaster oven, broiler, barbeque grill, or even inside the fridge for storing foods for a long time. Though they can resist a certain temperature level, they cannot withstand the high heat of an oven. 

Here are some possible reasons why you should not use a liner inside the oven. 

Possibility of melting/burning:

Slow cooker liners are made from nylon or polyester plastic. They can withstand heat up to 400 degrees Fahrenheit.

However, they cannot resist the high heat of an oven that can go up to 550 degrees Fahrenheit.  The high heat can melt or burn the plastic resulting in accidents. 

Not oven safe: 

Slow cooker liners are safe to use and BPA-free. So there’s no worrying about consuming anything unsafe.

However, the slow cooker liners are not labeled as oven safe. Hence, we are not sure whether the heat from the oven will release potentially harmful chemicals or not. 

Do slow cooker liners melt or burn?

Slow cooker liners do not usually melt or burn. They are made heat resistant. The material is either nylon or polyester that can resist temperature up to 400 degrees Fahrenheit. This is way beyond the temperature of a slow cooker.

Nevertheless, you should not put a slow cooker liner into the oven, broiler, barbeque grill, or toaster oven. These appliances tend to heat more than 400 degrees Fahrenheit. So there is a chance your slow cooker liner can melt or burn exposed to high heat.

What is the Reynolds slow cooker liner’s max temperature?

Reynolds has one of the best slow cooker liners. It is BPA-free and is not prone to breaking or leakage.  Like most slow cookers, this liner from Reynolds can also withstand heat up to 400 degrees Fahrenheit.

Are Slow Cooker Liners safe to use?

Slow cooker liners are safe to use. They are FDA-approved and are mostly BPA-free. So there is no way we will get exposed to harmful chemicals. Again, the minuscule traces of chemicals they may pass are not harmful to human health.

When purchasing, always make sure that you buy a slow cooker liner that is BPA-free.

Nylon or polyester are the materials of a slow cooker liner. They are heat-resistant plastic and can resist almost 400 degrees Fahrenheit of heat. Therefore, there’s no risk of melting or burning.

However, remember not to use them inside an oven, grill, or broiler. The liners may not resist the high heat and may cause accidents. Also, you should not use liners inside a fridge to store food for a long time. 

Always buy a liner that is of good quality. Do not settle for the cheap ones as they may break, burn, melt or create leakage. Also, you could expose your food to harmful chemicals.

Are slow cooker liners the same as oven bags?

Slow cooker liners and an oven bag are not the same. Though they are both made of plastic, there are some differences. Oven bags differ in size and shape from slow cooker liners. While oven bags have an opening at the end, the slow cooker liner opens at the wider side. 

Slow cooker liners are not suitable to put in the oven, toaster oven, or broiler and even on the fridge for a long period. Slow cooker liners are nylon or polyester made that can resist heat. They are made for one time only.

Now, in oven bags, you need to put foods first and then cook in the oven. They vary in size. They are also nylon or polyester made and heat resistant. They either come in a box or are sold in a roll. Again manufacturers of oven bags do not recommend them to use in the slow cooker.

What can I use instead of an oven bag or cooker liners?

If you do not want to use oven bags or slow cooker liners, you can adapt a few alternatives. They are either easy to use or cost less. Here we have listed three such options.  

Parchment paper: 

Using parchment paper, you can line a slow cooker pot. It will allow mess-free cooking. Again, parchment papers are cheaper compared to a slow cooker liner or an oven bag.

However, in foods with higher water content, you cannot use parchment paper. They may wear off or dissolve inside the pot.

Aluminum foil

You can use aluminum foil to put it along with the crockpot for cooking. Also, try making a lid for crockpots. 

Aluminum foil is heat resistant. However, research shows that aluminum foil can leach into food in certain circumstances. Also, high temperatures and acidic food can increase the leaching process.

Oiling the pot

How does oiling the pot works similar to liners? Oiling the pot will help you with less work when you need cleaning. The oil on the pot won’t allow stubborn stains for sure.

For oiling, you can use a standard cooking spray. Spray on the bottom as well as on the sides. Again you can use olive oil or vegetable oil. With hands, you can rub on the surface of the pots. 

Can roasting bags be used in a slow cooker?

When one wants to roast meat or other food items, roasting bags are needed. It is advised not to put roasting bags in a slow cooker.

In an oven, a roasting bag uses dry heat to cook. It does not require moisture from the outside. Slow cooker, on the other hand, uses steam and heat. Hence the cooking process is quite different in both of these appliances.

A roasting bag may not need steam to cook as it already can moist the food inside. Also, condensation on the lids provides a liquid in a slow cooker. In a roasting bag cooking process, this is not required.  

Can you pressure cook with a liner?

It is possible to pressure cook with a liner. The pressure inside will not affect the liner by breaking or making it leak.

We know a liner is made out of either nylon or polyester plastic. They can resist heat up to 400 degrees Fahrenheit. It is thus understandable a liner could withstand pressure mode as well.

Slow cook liners are safe to use in pressure cooker mode. In this way, you can even speed up the cooking process. It also conserves a lot of heat.

Final thoughts

Slow cooker liners allow cooking without mess inside the cooker. The material withstands a good amount of heat. However, liners cannot resist the high heat of an oven, a broiler, or a barbeque grill. It may lead to the burning or melting of liner plastic. Liners are again BPA-free and safe to use.
