A slow cooker is one of the easiest appliances to use. Add your ingredients, put the lid on, choose a setting, and let it cook slowly while you handle the rest of your day.
Because many slow-cooker recipes begin with browning meat or sautéing onions, though, it can be tempting to put the entire Crockpot directly on the stovetop and use it like a regular cooking pot.
That is where things can go wrong.
A typical slow cooker is not designed to be placed directly on a stovetop burner. The removable crock may look sturdy enough to handle heat, but the cooking vessel and the electrical heating base are designed to work together in a very specific way. Direct burner heat can damage the crock, create a dangerous hot spot, or cause the cookware to crack.
Understanding the difference between the slow-cooker crock and its heating base can help prevent an expensive mistake—and potentially a serious kitchen accident.
The Crockpot Has Two Separate Parts
Most traditional slow cookers consist of two main components:
The inner crock: The removable ceramic or stoneware vessel that holds the food.
The heating base: The electrical unit underneath the crock that provides gentle, controlled heat.
The crock is designed to sit inside the heating base so heat is transferred gradually around the vessel.
A stovetop burner works very differently. Instead of surrounding the crock with relatively gentle heat from the slow-cooker base, it concentrates heat directly against a small area of the cookware.
That difference matters.
Direct Stovetop Heat Can Crack the Crock
One of the biggest concerns is thermal shock.
Ceramic and stoneware cookware can be damaged when exposed to rapid or uneven temperature changes. A crock that goes from room temperature to intense burner heat can develop cracks or, in some circumstances, break.
The risk can be particularly concerning if the crock is cold, damp, damaged, or exposed to a sudden temperature change.
A cracked cooking vessel can leak hot food or liquid and may create a mess—or a burn hazard—if it fails while you're cooking.
The Heating Base Is Not Cookware
