The great thing about slow cookers is that you can place all of your ingredients in and let them cook for several hours unattended. If you need to get your slow cooker meal on the table more quickly, however, there are a few conversions you can make. When a recipe calls for 7 hours on low, you can set it for 3 hours on high instead; when it calls for 8 hours on low, set it for 4 hours on high; when it calls for 9 hours on low, set it for 5 hours on high, and so on. Following these conversions, you can cook your chicken, broth and dressing mix for 2 hours on high before proceeding with the rest of the recipe.
