This ravioli and sausage slow cooker casserole is so easy to make. Busy weeknights mean I sometimes struggle to get dinner on the table. On those nights, my crock pot is my lifesaver.

I have a whole list of slow cooker recipes that my whole family loves, like slow cooker chicken cacciatore, slow cooker BBQ ribs, and crock pot Italian beef, but this right at the top.

Simply toss all the ingredients in the crock pot, turn it on, and when you get home at the end of a long day you have dinner waiting for you. The diced tomatoes and tomato sauce cook down into a pasta sauce that takes on a great flavor from cooking with the sausage and basil all day.

The flavorful sauce coats the cheese ravioli and sausage and make a hearty meal that everyone in the family loves.

Garnish with a little fresh basil and grated Parmesan and then call everyone to the dinner table and watch them dig in. This is one of those easy weeknight dinners that is so good there are never any leftovers.
