Slow cookers have different temperature ranges, and the high setting can vary depending on the model. However, most slow cookers reach the simmer point and stabilize on both "High" and "Low" at about 209°F. Slow cookers are designed to cook food at lower temperatures, and the temperature range is typically between 175°F to 215°F. The low and high settings will peak at 215ºF, but the low setting cycles on and off that temperature more frequently. Therefore, the high setting will cook the food in a shorter time than the low setting.

It is important to note that the high setting does not necessarily mean that the food will cook faster. Some cuts of meat will overcook on high, while root vegetables, especially potatoes, take longer to cook than meat and often need high in order to cook for long enough. A rule of thumb is that 4 hours is about right on low to hit the cooking temperature, and two for high. You then add on the rest of the time to achieve cooking at a steady temperature, which is why a low recipe for stews can often say 8-10 hours.

If you are converting an oven recipe to a slow cooker, you can use the owners manual to check the temperatures for low and high settings. Generally, low is about 200 degrees Fahrenheit, and high is 300 degrees Fahrenheit. If you want to shorten baking time by using a higher temperature in the oven, youll have to do a little bit of math. For high setting, divide the time by 2 and bake at 325 degrees Fahrenheit.

In summary, the high setting on a slow cooker can vary depending on the model, but most slow cookers reach the simmer point and stabilize on both "High" and "Low" at about 209°F. The temperature range is typically between 175°F to 215°F, and the high setting does not necessarily mean that the food will cook faster.
