If dinnertime is hectic in your household, a slow cooker will make your life much easier, allowing you to prepare a wide variety of meals in advance, giving you time to get other things done. When dinnertime rolls around, you can simply serve the meal from from the slow cooker. Even a simple meal like cheese ravioli can be made easier when you toss prepared ravioli into your slow cooker a few hours ahead of mealtime.
Pour enough of your favorite pasta sauce into slow cooker to cover the bottom, then add a layer of cheese-filled ravioli, then another layer of pasta sauce. Repeat layers until you have added all the ravioli you are making, with pasta sauce being the top layer. You can use any type of pasta sauce you prefer, whether it's a tomato-based sauce or an Alfredo cheese sauce.
Add any additional ingredients of your choice. If you want your cheese ravioli to be even cheesier, add a generous handful of shredded cheese. Add a 1/2 cup of pesto sauce, or a handful of minced garlic to enhance the flavor of the pasta sauce. You can also add cooked ground beef or turkey for a heartier ravioli dish. All of these are optional additions that should be layered into the dish. You can add additional ingredients on top of each layer of ravioli. Whatever you choose to add, the final layer should be pasta sauce.
Cover the slow cooker and cook the ravioli on the low setting for about three to four hours. The ravioli is done when they are fork tender. Depending on the amount of ravioli and your specific slow cooker, it might take up to an hour or so longer to cook. After three hours, briefly check to see if the ravioli is tender by piercing a couple with your fork. If they are not done, check on them again in an hour. If you need them to cook faster, you can turn the slow cooker setting to high and check on them every 30 minutes.
