Why I Love This Chicken Casserole
If you’re looking for a weeknight dinner, cheesy chicken casserole is your answer. It’s super quick to make.
You can use leftovers or rotisserie chicken or make poached chicken breasts (it’s great with baked chicken breasts too)!
Swap out the cream of chicken soup for cream of mushroom or celery in this dish.
This cheesy chicken casserole can be prepped ahead of time and kept in the fridge until you’re ready to bake it meaning you can make it tonight and cook it tomorrow!
Ingredient Notes
This easy chicken casserole can be adapted to use whatever you might have in your fridge:
- Chicken: Swap it for turkey or ham if it’s all you have on hand.
- Pasta: Any medium pasta will work in this recipe. Be sure to cook it al dente (so it’s still a bit firm), it’ll cook more in the oven.
- Vegetables: Cook and/or drain your veggies before adding to this casserole. Mushrooms, diced tomatoes (drained if using canned), leftover Grilled Zucchini or roasted veggies all work well.
- Sauce: Use cream of whatever-you-have-in-your-pantry (or make a homemade condensed mushroom soup). Of course any kind of cheese goes here!
- Topping: Chicken casseroles are a staple basically everywhere, usually topped with cheese. It’s also great with a bread crumb topping. Combine 3 tablespoons panko crumbs with 1 tablespoon melted butter (add a bit of garlic powder, salt & pepper too). Sprinkle overtop and bake as directed.
How To Make a Cheesy Chicken Casserole
The steps to make this chicken casserole are pretty simple:
- Boil pasta al dente.
- Soften onion and peppers in butter.
- Mix the sauce ingredients and cheese. Stir in chicken and pasta.
- Top with cheese and bake until bubbly.
Serve it with your favorite sides and enjoy!
How To Reheat
To reheat it, just pop it back in the oven at 350 for about 20 minutes! If the sauce is a creamy sauce like a mac and cheese, I usually add a dash of milk and cover before heating.
If you are using the microwave to reheat the cheesy chicken casserole, add a splash of milk to the dish and stir it half way through cooking to keep it from drying out.

Cooking is not my greatest talent, but this recipe is fantastic! Everyone who ate it raved about how good it was and said they couldn’t believe “I” made it
My husband is still talking about it today!
So glad you were able to impress your family with this recipe, Candace! :)
This dish is delicious! Unfortunately I did something wrong and mine is soooo runny! I don’t know what I did wrong nor how to correct it. It’s more like a cream based soup or a pot pie than a casserole.
I will definitely try it again, though.
Did you add extra liquid to the soup or did you use it condensed right from the can?
Hi Holly
I used condensed right from the can. No liquid other than the milk was added.
Thanks
Hmm, I can’t say for sure what went wrong as I haven’t had that problem before. I’m sorry it didn’t work out for you.
We are making this and having a lot of fun! We want to eat it later. Should we cook it and reheat it later, or should we not cook it at all, pop it in the fridge and just bake it once? So far it smells delicious!
I would suggest baking just before eating if possible.
So yummy and SO easy! Thank you!!
Loved this recipe! Even my husband, who is not a casserole fan, liked it! Will be making again for years to come!
I love this recipe but it always makes so much and we are not big on leftovers, do you have a recipe for an 8×8 or 9×9 pan???
Hi Carrie, we don’t have a version of this recipe for an 8×8 or 9×9 but you could half the recipe and bake it in a 9×9 pan if you would like :)
I made this delicious casserole tonight and it was a hit! I used cream of onion soup instead of cream of chicken for a little more flavor. I also cooked my chicken in my pressure cooker with Holly’s recipe before assembling the casserole. It took under an hour from start to finish!
So glad you loved it Natasha, I bet the cream of onion was delish in this!!
What could I sub for the chicken soup? I have all the ingredients but that one. Love your recipes! They are great for my family of 10
Do you have “cream of” anything else? If not, I have a homemade condensed cream of mushroom here.
No I dont have any condensed soups and no mushrooms
You can add in your favorite veggies in place of the mushrooms and try your hand at making your own condensed “cream of” soup
Holly, I just want to tell you how much I love your recipes. I get so excited to see a new one and they’re always so delicious. Thank you and God bless you and your family.
Aww thank you so much Erica! I’m so glad you’ve loved them!
Looking forward to making this soon!
One of my all time favorite recipes. My husband and daughter love it, as well. My picky daughter didn’t pick anything out of it. She devoured the first serving and came back for seconds. Will definitely make this over and over again.
That is great Anna! So happy you all enjoyed it.
I’m making this recipe for my family however how do you recommend cooking the chicken?
Hi Makenna, you can use any leftover cooked chicken you have on hand. You can also use oven baked chicken breasts or poached chicken for this recipe. Both would be delicious!
I’m going to try some of these yummy recipes.
I would love some new recipes. Also love casserole dishes

I made the cheesy chicken casserole, and although the nutrition information is noted, it does not specify what the serving size is for the nutritional information provided. Would you happen to know what serving size that information is based on? In
Hi Ronda, the nutrition information is for ⅙ of the casserole. This would be approximately 1 to 1½ cups per serving.
Great recipe!! My husband does all the cooking but I will get in the kitchen if I find a recipe I wanna try…We are a family of 6 so this was perfect..It pleased everyone even the picky eater..Definitely will make again. Thank you
So glad your family loved it!
Looks good
Can this be cooked and frozen for quick reheating later?
I haven’t tried freezing this recipe although dairy doesn’t always freeze well.
Seriously, this is delicious and even better the next day.
Loved this! I cut the chicken up and baked it seasoning it with black pepper, seasoned salt, onion powder and smoked paprika. I didn’t have shells so I used rotini. Otherwise followed the recipe. Will definitely make this again!
Need recipes for 2 elderly people. This would make to much. But looks great.
You can also freeze this, if you decide to make it Mary! This might help :https://www.spendwithpennies.com/how-to-freeze-a-casserole/
