At higher temperatures, some materials in appliances are prone to react with acidic foods. You can avoid such reactions by opting for ceramic slow cookers, which aren’t toxic.

You can place ceramic slow cookers on your dining table or counter and serve the food directly.

Ceramic is also safe for oven use as it can tolerate temperatures as high as 400 degrees F.

You can also store food in ceramic inserts and place it in your refrigerator. Unlike metal inserts, ceramic will not alter the taste of the stored food.

Additionally, ceramic slow cookers are suitable for the dishwasher as well!

On the other hand, aluminum slow cookers do not offer as much flexibility. For example, it is dangerous to heat aluminum in ovens.

It is not advised to store aluminum inserts in the refrigerator too. It may impart a metallic feel to your food.


Once you’ve purchased a ceramic slow cooker, it will last you for years!

Ceramic is the kind of material that is not easy to scratch or dent. This makes them highly durable and resistant to damage.

It is also essential to maintain your ceramic cooker to last longer. Ceramic slow cookers are safe to use for 6 to 10 years.

Aluminum slow cookers are metal. Metal surfaces are susceptible to scratches and other damage.

As aluminum slow cookers cannot withstand as much damage, you’ll likely have to purchase a new one after 2 to 3 years.


Slow cookers come in various sizes and offer different features. For this reason, they all have different price points.

It is always best to pick a slow cooker that isn’t too hard on your pockets.

You can find aluminum slow cookers that are under 50 dollars as well.

However, as their durability is in question, you may have to repeat the purchase, which becomes pricey.


Ceramic cookers are better when it comes to safety. It is true that both ceramic and aluminum slow cookers are safe for daily use.

However, aluminum slow cookers are more prone to degradation. When this happens, it is easier for aluminum to mix with the food you cook.

So, if you want impeccable safety from your slow cooker, it is best to choose ceramic materials

Pros of Aluminum Slow Cookers

The aluminum slow cooker has its share of benefits to offer. Let’s look at some of them! 

Cooking Capacity

When you’re slow cooking, you’d probably want a cooker that accommodates more significant quantities of food. So, which slow cooker is better for this? 

If you have a big family to serve or a party coming up, it is best to cook in aluminum slow cookers. Aluminum slow cookers uniformly cook large amounts of food placed in it. 

Ceramic slow cookers do not serve this purpose as well as aluminum cookers.

It is not advised to cook large food quantities in ceramic cookers. They are best for personal use or small dinners.

Here are some excellent options for an aluminum slow cooker that you can check out!

  • All-Clad Slow Cooker: Along with offering sufficient space for large dinners, this slow cooker cooks in 4 modes. The glass lid helps you see your food and gives the cooker brownie points!
  • All-Clad Gourmet:  This cooker provides a programmable timer of 20 hours. It is one of the best in the market because of its quality and efficiency!

Metal Conduction

Metals conduct heat at a faster rate.

So, aluminum heats up faster than ceramic. While both materials are good at retaining heat, aluminum slow cookers offer fast heat conduction. 

Ease of Cleaning

Objectively speaking, both ceramic and aluminum inserts have a non-stick surface. So, all you need to do is rinse them with soap and water after each use.

The only plus point when cleaning aluminum inserts is that they are lighter. Ceramic inserts are heavier and bulkier to deal with while cleaning.

Finally, the Winner! 

We’ve discussed various features of slow cookers that make them stand out.
