Choose a jarred sauce that you really enjoy but one that is on the plain side (sauces with large flecks of herbs and lots of garlic or onion powder do not hold up well in the slow cooker). The ravioli should be medium-sized; the extra-large ones tend to fall apart upon serving. If you purchase refrigerated ravioli, freeze them yourself before using them in this recipe.

I live with 5 very ppicky eaters. what one likes the others cant stand and vice versa cooking is always a task for me! i made this recipe exactly by the directions(disregarding dislikes in my house) and there were no leftovers. GREAT RECIPE

Thanks for this recipe. I was super rushed for time and did not make the sauce as directed- I just used plain canned sauce so the taste was a little on the plain side- which is why I did not rate it as I'm sure if I followed your directions it would have had a little more zip. I love how easy this recipe was and it makes a ton. I also added a layer of baby spinach and sliced mushrooms and they cooked up perfectly. I am super happy to find this recipe and to know how to use the frozen raviolis in this way. Next time I am going to make up the sauce as you directed, but will only use one bag of ravioli and will use more veggies. Thanks for posting this!

YUM!This was perfect. Nice and hot and cheesy, but didn't heat up the house during a hot arizona summer day. Hubby said that I could make this one again, so its a keeper.
