It depends on the specific crock pot you have. Traditional ceramic crock pots that come with a separate ceramic insert or dish are typically not oven-safe. The ceramic used in these inserts may not be able to withstand the direct heat of the oven and can crack or shatter if exposed to high temperatures.
If you want to use the crock pot's ceramic insert in the oven, make sure to check the manufacturer's instructions or the product's packaging to see if it is oven-safe. If it is not explicitly mentioned as oven-safe, it's best to avoid using it in the oven to prevent any potential accidents or damage to the crock pot.
Alternatively, some modern slow cookers or multi-cookers come with oven-safe inserts made from materials like stainless steel or other heat-resistant materials. These inserts are explicitly designed to be used in both the slow cooker base and the oven, providing more versatility in cooking.
In any case, if you're uncertain about the compatibility of your crock pot's ceramic insert with the oven, it's safer to use oven-safe cookware specifically designed for oven use to avoid any risks of damage or injury.
