Let’s have a look at the designs with ceramic inner pots as well as those with metal inserts.

When it comes to convenience and simplicity in the kitchen, slow cookers have revolutionized meal preparation. Nothing beats the convenience of coming home to a ready-made nutritious meal at the end of a busy day.

The automatic ‘set and forget’ types offer this. Units with an automatic keep warm setting have meals maintained at the right temperature until ready to serve and a slow cooker is not just about cooking stews. There’s a multitude of easy slow cooker recipes available on the web involving various cuts of meat and vegetables to keep family meals interesting.

Stainless steel vs ceramic vs aluminum insert

Slow cookers have an outer shell with a heating element in the base, above which sits an inner pot made of stainless steel, ceramic, or aluminum. The slow cookers and multi-cookers with metal pots are popular right now. Manufacturers realize that folk prefer easy clean-up and so market slow cookers with nonstick metal pots.

As with any type of kitchen appliance or cookware you purchase, it’s important to know that the unit that slow cooks meals over an extended time is safe. Most folk don’t want potentially harmful chemicals leaching into their food.

Aluminum nonstick inserts of small appliances

Most aluminum inserts have a coating of Teflon and some have ceramic nonstick. You might enjoy home-cooked meals in a slow cooker but find the clean up a drag. The advantage of nonstick pot inserts is an inferred easier clean up.

The downside: Both Teflon and nonstick ceramic coating deteriorate over time with use resulting in the aluminum base coming in contact with the food you are cooking in this kitchen appliance. I wrote about the potential concerns with aluminum in my article on cookware materials and their safety.

When you purchase a slow cooker with a coated aluminum cooking pan, you can almost guarantee that you’ll be looking to replace it within a year or two, depending on the amount of cooking you do.

The good thing is that since 2012, regulations require all nonstick cookware sold in the US to be free of perfluorooctanoic acid (PFOA). And though Teflon pans used on very high heat does have safety issues around the harm of the fumes for birds and being linked to flu-like symptoms in humans (I share more details in my article on ceramic vs Teflon), the temperature of heat settings used in a slow cooker is not likely to reach these concern levels.

Opting for a slow cooker with stainless steel pot

Stainless steel is a durable option. An inner pot of stainless steel contains chromium and nickel. A 2013 study found certain grades of stainless steel react with acidic tomato sauce and significantly increase the levels of nickel in the food, which is a concern for those with nickel sensitivities for whom nickel-free stainless steel cookware is a viable option.

Meanwhile, a 2017 study found food-grade 18/10 stainless steel is safe in that the amounts of nickel and chromium released “were below known allergy-triggering thresholds”. The 18/10 ratio refers to the amount of chromium and nickel, respectively. You can read more about this in my review of Made In stainless steel range.

One downside is that the metal surface is prone to scratches from the use of metal spoons or knives. Also, stainless steel can discolor, but if it does, you can easily remedy the problem.

Choosing a ceramic inner pot

Ceramic inserts of slow cookers are typically 100% ceramic and non-toxic. Think of the original crock-pot. The glazing of the ceramic means it will withstand scratching. In this respect, ceramic is the most durable and long-lasting. Those sold in the US have lead-free glazes, required as part of the FDA approval, meaning there’s no added coating that might pose a risk to you or your family.

Ceramic does not react with acidic foods such as tomatoes and you can store the leftover food in the ceramic pot covered with the glass lid in the refrigerator without having to worry about the flavor being tainted by a metal container. And, the glazed ceramic surface makes them not only easy to clean but also appealing for table serving.

Downsides: Ceramic pots are not as lightweight as the metal ones. Extreme thermal shock and accidentally dropping the insert can damage ceramic pots beyond use.
