A slow cooker temperature ranges between 200 and 300 degrees Fahrenheit, and most have multiple settings for cooking time and temperature. Although it's a trademark, some use the term Crock Pot when referring to a slow cooker.
The temperature of a slow cooker requires a much longer cooking time than a conventional oven. Generally, food cooked in a conventional oven for 30 to 45 minutes cooks for six to eight hours on a low setting in a slow cooker. Any food can cook in a slow cooker, but some recipes may require changes to obtain the desired flavor and texture. A slow cooker uses significantly less energy than a conventional oven.
