Casseroles are some of the most comforting foods that come out of your kitchen. But they take some prep work, and that’s not always the best after a long, busy day. Enter: the slow cooker. Lots of your favorite casserole recipes translate to your Crock-Pot so you can do any prep work hours ahead of time. 

Here are some homey, delicious casserole recipes you can set and forget in your slow cooker.

Frozen ravioli is the key to the convenience of this dish. The recipe calls for beef ravioli, but you can use cheese or spinach ravioli for a vegetarian meal.

Chicken and rice casserole is a comforting, versatile dish. This one is seasoned with Italian herbs and garlic, but you can easily swap those out for poultry seasoning and thyme for a more homestyle version. Because the instant rice is only put in near the end of cooking, it doesn’t get mushy.

This recipe is like jazzed up baked pasta. It’s full of ground beef and sliced pepperoni, plus pizza sauce, of course. A can of cream of mushroom soup makes everything a little creamy, too. If you like other things on your pizza, like mushrooms or olives, they’d go great in this dish as well.
