Why You Should Never Put Your Crockpot on the Stovetop

Could I use the cooktop to cook in a crockpot?
No way! Crockpots aren’t meant to be used on stovetops. Soups, stews, and chili are perfect for crockpots, which are slow cookers that utilize low heat to cook food for a long time. You shouldn’t heat the ceramic insert of your crockpot on a stovetop burner, but rather on the low, continuous heat of a slow cooker. For the following reasons, it is not safe to place a crockpot on top of the stove:

The porcelain crocks used to make crockpots and slow cookers are fragile and may crack or shatter when subjected to sudden changes in temperature or direct heat. You are subjecting a ceramic insert to a kind of heat it was never designed to handle when you place it on a burner. Electric or gas stove burners provide a concentrated beam of heat that may swiftly bake ceramics. The bottom of the crockpot might fracture or even come off, as seen in the now-famous Facebook post, because of this.

Just what may occur?
Several unsavory things could happen if you set your crockpot on the burner. In most cases, the ceramic insert will crack or chip, leaving a mess on the stovetop. The meal becomes quite hot, which not only creates a lot of mess but also poses the danger of burns. Additionally, if your cooktop is ceramic or glass, the ceramic bits might potentially damage it.

And that’s not all either. On the other hand, the ceramic insert might develop tiny, unseen flaws rather than breaking instantly. Because of these fissures, the crockpot may no longer be sturdy and may split the next time it’s used. If the crockpot’s heating element becomes broken during cooking, there’s always the chance of electrical hazards.

Would a ceramic dish be okay to use in a stovetop oven?
Do you know if any ceramic dish will be safe to use on a stovetop? In most cases, the answer is no. You shouldn’t use most ceramic dishes on a stovetop burner. Although flameware and ceramic cookware are the exception rather than the rule, there are specialized pots that may be used on the stove. When placing any ceramic dish in the oven or microwave, be sure to read and adhere to the manufacturer’s instructions.
