Some recipes are designed for Crock-Pot slow cookers. In most cases, you can still make your favorite slow-cooking dishes in the oven. Slow cookers vary, so there is no exact conversion time for slow-cooker recipes. Converting the cook time will also depend on the dish. Most Crock-Pots and other slow cookers have a low setting which is usually 200 degrees F; the high setting is generally 300 degrees F. There are some general guidelines that will help you convert the cooking time from slow cooker to oven.
Preheat the oven to 325 degrees F. Combine your ingredients using half of the liquid your recipe calls for. When cooking in the oven as opposed to a Crock-Pot, you will need less liquid. Place the ingredients in an oven-safe casserole dish. Cover.
Convert the Crock-Pot cooking time for low settings. If a dish requires cooking in a Crock-Pot on the low setting for 4 to 8 hours, it will usually only require 15 to 30 minutes in the regular oven. For items that take 6 to 10 hours in the Crock-Pot on the low setting, plan on cooking in the oven for 30 to 40 minutes. Slow-cooker recipes that call for 10 to 12 hours on the low setting should be cooked in the oven between 1 1/2 and 2 1/2 hours; those longer than 12 hours should be cooked in the oven for 3 to 5 hours.
Figure out the oven cooking time for Crock-Pot recipes on high settings. If the recipe calls for a dish to be cooked in the slow cooker on a high setting for 1 1/2 to 2 1/2 hours, you can cook it in the oven for 15 to 30 minutes. For Crock-Pot recipes that require 3 to 4 hours cooking on a high setting, place in oven for 30 to 40 minutes. For dishes that would be cooked 4 to 6 hours on the high setting, the converted oven time would be 1 1/2 to 2 1/2 hours.
Check meat for doneness by using an internal meat thermometer. Place thermometer in the thickest part of the meat. For beef, pork, lamb and veal steaks, chops and roasts, the minimum internal temperature should be 145 degrees F. Ground beef, pork and lamb, along with poultry, should be cooked to 165 degrees F.
