1. Crockpot Green Bean Casserole

Total time: 3 hours and 10 minutes

Green bean casserole is a classic dish to cook with your Crockpot for Thanksgiving and Christmas feasts. However, you can whip it up without heating the kitchen using your trusty Crockpot and save the oven space for your turkey and other mains.

This recipe is meant for feeding a crowd, as it can accommodate up to 10 servings. It’s perfect for any big meal where your oven is overworking with other dishes.

On the note side, French fried onions are at their best when served immediately. Avoid adding them to the casserole unless you’re ready to serve, or they’ll lose the savory crispness and crunch.

This crockpot enchilada hits the right spot for nights when you crave a bit of everything in a bowl. There are chicken, black beans, corn, green chiles, cheese, and more. What’s not to love? Plus, a dish is always healthier with quinoa, after all.

4. Slow Cooker Taco Casserole

Total time: 2 hours and 30 minutes

This Mexican-inspired casserole will take your Tuesday taco night to a whole new level. I love that I can sneak in plenty of veggies and make everyone eat their greens without complaint.

Also, feel free to throw in your family’s favorite veggies (mushrooms, avocado, and green peppers all work great in this recipe). This taco casserole starts with browning the ground beef and then cooking the taco mixture (including veggies, beans, and taco seasoning, etc.).

Then, assemble the taco in the Crockpot before cooking the whole thing on high heat for at least 2 hours. Leftovers can last 3-4 days when refrigerated, yet make sure you allow the casserole to cool to room temperature first before tossing it in the fridge!

This Mexican-inspired taco casserole starts with your trusty slow cooker.

5. Slow Cooker Tamale Pie

Total time: 6 hours 30 minutes

Don’t let the name fool you! This tamale pie is among these straight-up casseroles with flavorful ground beef and a cornbread topping. Besides, it’s a well-loved dish in Southwest cuisine.

You’ll love the convenience of this quick and easy recipe, which uses a cornbread muffin mix and canned beans. The cornbread topping, in particular, is a game changer for the tamale pie. Just make sure you add it in the last hour of cooking.

7. Slow Cooker Four Cheese Mac And Cheese

Total time: 2 hours 55 minutes

Mac and cheese is always a classic that everyone can’t get enough of. This version is ultra-rich and creamy by mixing up to 4 types of cheese (Cream cheese, Parmesan, American, and Cheddar).

Yet, feel free to sub in your favorite cheese, as long as it has good melting properties. Like with most recipes here, everything heads right to one pot. There’s no need to cook the pasta separately. No boiling involved, either!

The whole milk, cheese, evaporated milk, and seasoning slowly melted into a creamy sauce. Yet, ensure to stir the casserole halfway through, and then stir again before adding Cheddar cheese.

8. Slow Cooker Chicken Tater Tot Casserole

Total time: 5 hours and 25 minutes

Tater tot casserole is among the first dishes to disappear at the potluck. It’s similar to the hash brown casserole, but this flavorful slow cooker dish is full of chicken and crumbled bacon. These ingredients turn tater tot casserole into a rightful main rather than a side dish.

Here’s the tip: Tater tot is best slowly cooked on low heat, so their edges won’t burn. This means that the dish will have to stay a bit longer in the pot.

On the bright side, there’s no stirring required. It’s not recommended to open the lid during cooking, as well. For this reason, you can toss everything in your slow cooker, do other tasks, and come back only when the time is up.

9. Crockpot Hashbrown Casserole

Total time: 4 hours and 5 minutes

The ultimate cheese comfort food is made easier with a little help from your Crockpot. You’ll only need to dump all the ingredients (reserve the parsley, though) in the pot, give them a good stir, and cook on low for 4 hours.

Incredibly cheesy and soft, this casserole can be served as breakfast or dinner. It’s a comforting side for poultry and meat. If you’re serving it for breakfast, fried bacon or sausage will make a lovely addition.

Either diced or shredded potatoes work wonders here and give a good texture. It’s all about personal preferences! If you prefer shredded potatoes, mind your cooking time!

This hashbrown casserole is classic comfort food made easier by using Crockpot.

10. Slow Cooker Sausage Casserole

Total time: 7 hours and 15 minutes

Nothing like digging into a comforting and filling dish on a chilly night. This take on the classic French cassoulet uses Toulouse-style sausages, which originate from French, to mimic the authentic flavors as close as possible.

Pork lardons are also added, so everyone has more choices for protein. Meanwhile, the mellow and creamy white beans offer a backdrop for the flavors of tomatoes and herbs to shine.

The mashup of reduced wine, tomatoes, chicken stock, and paprika creates the flavor base for the entire dish. Serve this bean-and-meat casserole with crusty bread, as you’ll need something to sop up the delicious sauce at the bottom of the Crockpot.

On the note side, always brown the sausage first (just as you would with ground beef for a slow-cooked stew). This intensifies the flavors and firms up the sausage’s skin.

11. Slow Cooker Tater Tot Cowboy Casserole

Total time: 6 hours and 30 minutes

This family-friendly Cowboy casserole is both creamy and hearty. It’s layered with seasoned ground beef, veggies, black beans, and plenty of melted cheese. Using only basic pantry ingredients, this slow-cooked recipe is an economical way to feed a crowd.

When the casserole is done, make sure to let it rest uncovered for 15 minutes before enjoying it. The dish holds a lot of heat, so allow it to cool down to an edible temperature.

12. Lamb Casserole In The Slow Cooker

Total time: 6 hours and 40 minutes

Ward off winter blues with this meltingly tender lamb cooked in rich, creamy gravy. The gravy is everything in this casserole. It’s made of lamb stock, dry red wine, Worcestershire sauce, etc., thickened by the cornstarch.

Feel free to swap in chicken or beef stock if you like. However, mind the amount of salt you add if you use store-bought stock. The stock is already salty, so only check the gravy in the last hour of cooking to see if it needs more salt or not.

The dish is hearty with potatoes and meat, so you only need a veggie side dish to round out your dinner.

13. Slow Cooker Breakfast Casserole

Total time: 8 hours 15 minutes

The key to an egg breakfast casserole is the egg-to-milk ratio. This recipe whisks 12 eggs with half a cup of milk.

Stick to this ratio to get a fluffy texture, or your dish will turn out either tough or overly smooshy. The base also has a lovely tangy note and creamier texture, thanks to the sour cream.

The best thing about this casserole is you can top the base almost with anything you want. Here, pre-cooked bacon and sausage add savoriness and also makes this breakfast such a snap to put together.

In this recipe, cans of cream of mushroom and chicken soup make your life even easier (in addition to the slow cooker).

This casserole is the best choice if you are looking for a winner in the next potluck. Because it’s already filling and hearty in its own right, a light side such as roasted broccoli and cauliflower or a side salad is what you’ll only need for a complete meal.

16. Ham And Cheddar Slow Cooker Breakfast Casserole

Total time: 8 hours 15 minutes

Pop this casserole into the Crockpot and let it slowly cook overnight. This means that breakfast is ready to serve for your action-packed mornings. Another bonus: this dish is a great way to use your leftover ham.

This creamy and cheesy slow-cooked dish is quite similar to Hashbrown casserole. What sets them apart is the ham chunks and other meats (if you wish).

You can also add bacon and sausage for extra flavors. Nevertheless, make sure they are pre-cooked and crumbled before going to the slow cooker.

17. Crockpot Sweet Potato Casserole

Total time: 4 hours 20 minutes

Sweet potato casserole is a crowd-pleasing slow cooker dessert. It’s also a staple on Thanksgiving, traditionally served alongside roast turkey. The Crockpot makes whipping up this comforting casserole almost effortless, so you’ll have more time for other dishes!

This Thanksgiving must-make is also highly adaptable. If you don’t fancy the candy-like element of marshmallows, simply leave them out.

The casserole still has enough sweetness, thanks to the brown sugar. If you include marshmallows, reserve them until the last 15 minutes of the cooking. Plus, when pecans are unavailable, simply substitute them with walnuts or hazelnuts.

If your turkey already occupies the oven space, make this Crockpot sweet potato casserole as a Thanksgiving side.

18. Cheesy Ravioli Meatball Casserole

Total time: 3 hours and 10 minutes

Using only 5 ingredients, you’ll have a flavorful slow-cooked pasta dish full of meat and cheese. You might be skeptical about the ready-made seasoning package. Yet it offers a wonderful shortcut and still imparts tons of flavors to the casserole.

This spice flavor goes exceedingly well with marinara sauce, bringing out a savory sauce that seeps into the meatballs and pasta.

Whether you’re using store-bought or homemade meatballs, cook and freeze them before adding them to the casserole. The same goes with pasta; meat-based or vegan ravioli works just fine as long as they’re frozen.

19. Slow Cooker Chicken Parmesan Casserole

Total time: 4 hours 30 minutes

If you love chicken Parmesan as much as the next person, this slow-cooked casserole is worth a try. You can still enjoy all the elements of chicken Parmesan without having to labor over it. Thanks again, slow cooker!

The appliance low and slow simmers the chicken breast until it gets tender. The blanket of simple but rich Prego Traditional sauce imparts so much flavor to the meat.

There’s also the melty, gooey layer of salty Parmesan and Mozzarella cheese. The latter contributes to the creamy, stretchy texture that everyone can’t get enough of.

Penne pasta is one of the best choices for this casserole. The small shape, as well as the ridges, capture all the cheesy goodness.

You just need to cook the pasta slightly under al dente since it will continue to cook with the sauce. Pro tip: minus one minute from the recommended time on the package.

20. Creamy Slow Cooker Tuna Noodle Casserole

Packed with Mexican flavors, this comforting cornbread casserole is perfect when your craving for Mexican food hits. Green chiles, shredded Mexican cheese, and ground beef are nestled between two layers of cornbread.

Yet, it takes less effort as there’s no rolling required. Just toss all the ingredients in the Crockpot, stir and let the casserole slowly cook all day long. For this recipe, however, you might want to add more salt because the ingredients are quite bland.
