Adjust Cooking Time
For every hour you'd cook something in the oven or on the stove, allow 8 hours on low or 4 hours on high. (When in doubt, turn it on low and leave it all day or overnight.) The LOW setting on a slow cooker is approximately 95 degrees C and HIGH is about 150 degrees C.
Cuts of Meat and Chicken
While you can cook just about any kind of meat in the slow cooker, some cuts are better than others. Chicken on the bone, as well as cheaper cuts of beef, lamb and pork work really well in the slow cooker.
