Green bean casserole is a classic standby 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 green bean casserole, with tender veggies and crunchy French fried onions, is always a family favorite!
Total time: 6 hours and 30 minutes
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.

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.

Don’t let the name fool you! This tamale pie, which contains a flavorful ground beef base and cornbread topping, is a straight-up casserole. 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.
A sprinkle of cheese is a welcome addition here. This tamale pie is hearty and comforting enough, so it asks for no more than a light green salad to become a complete dinner.
Total time: 2 hours 5 minutes
This hearty casserole is packed with pizza flavors. Serve it for your next dinner, and everyone, from youngest to oldest, will ask for a second helping.

The biggest bonus is that you’ll only need 5 minutes to prep and let the slow cooker do the rest. Have a busy night but still want to make everyone happy? This is the one for you.
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.
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 tater tot casserole has lots of meat.
Crumbled bacon and chicken breast are in use here. 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.
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.
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.
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.
In this casserole, cheese and sour cream together give a touch of creaminess. There’s also a cheesy blanket of tater tots on top, which gives the whole dish extra heartiness.
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.
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.
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.
Breakfast casserole is meant for making ahead, and thanks to the Crockpot, you can get a tasty, filling breakfast with minimal work.

This Velveeta broccoli rice casserole will help your holiday feast a bit less stressful. It is everything a good casserole should be: comforting, creamy, and low-effort.
In this recipe, fresh broccoli is cooked until tender and combined with the fluffy rice in a creamy, cheesy sauce. The Velveeta cheese, white wine, cream of mushroom soup, and chicken broth make the sauce a rich flavor to go with the rice and veggies.
Melted butter and crushed crackers would make fantastic additions to this casserole (if you like some extra crunch).
Total time: 3 hours and 15 minutes
King Ranch casserole is a Southern classic bursting with chicken, cheese, and tortilla chips. Plus, layers of Doritos add an exciting crunch to every bite.
While there are varying renditions of King Ranch casserole, the sauce is quite the same. It normally consists of diced tomatoes with green chiles, cream of mushroom soup, and cream of chicken soup. Thus, the flavors are quite mild and family-friendly.
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.
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.
Total time: 4 hours 20 minutes
Sweet potato casserole is a crowd-pleaser. It’s a staple on Thanksgiving spread, 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 pot has creamy, tender chunks of potatoes topped with toasted pecans and sweet marshmallows. The ground cinnamon helps infuse a touch of warmth into this sweet dish.
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.
Total time: 3 hours and 10 minutes
Made with only 5 ingredients, this casserole is flavorful, meaty, and cheesy all in one dish. 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.
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.
Total time: 3 hours and 15 minutes
Tuna noodle casserole is a comfort food favorite, which is tuna, peas, and noodles cooked in canned cream of mushroom soup. This slow-cooked rendition goes without the mushroom soup and uses the creamy Alfredo sauce instead.
Start with cooking the pasta. Next, pour in the sauce, combine other ingredients like peas, tuna, and cheese, and then pour the mixture into the Crockpot. Like any good tuna noodle casserole, top this comforting pot with lots of panko bread crumbs and Parmesan cheese.
