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.

Cooking Sausage in Slow Cooker

Can you put raw sausages in slow cooker?

Yes, it is safe to put raw sausage in the slow cooker. It will cook with the other ingredients to make a flavorful sauce for the ravioli.

How long do raw sausages take to cook in a slow cooker?

To ensure your sausage is fully cooked, we recommend cooking for 4 hours on low heat. This dish is best cooked on the low heat setting so you don’t overcook the ravioli.

Can you cook frozen sausages in slow cooker?

For the best results you should use thawed sausage in the slow cooker. The frozen sausage will need to cook longer which will result in mushy ravioli.
