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!

Tips & Variations

This easy chicken casserole can be adapted to use whatever you might have in your fridge:

Chicken casseroles are a staple basically everywhere, usually topped with cheese.

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.

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.

Chicken: swap it for turkey or ham if it’s all you have on hand.

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 Chicken Casserole

The steps to make this chicken casserole are pretty simple:

  1. Boil pasta al dente.
  2. Soften onion and peppers in butter.
  3. Mix the sauce ingredients and cheese.  Stir in chicken and pasta.
  4. 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.

Serve With

This chicken casserole recipe is simple and doesn’t need much for sides. A fresh tomato or kale salad and some crusty bread or 30 Minute Dinner Rolls make the perfect meal!

  1. This is awesome. I used fajita-seasoned cooked chicken from the grocery store — it really added a great kick to it!5 stars

  2. I changed around a few things and it turned out delicious. I had to keep a toddler in mind as to seasoning, so I went light on it and disguised broccoli, red bell pepper, and carrots by processing them to tiny pieces. I used a can of shiitake mushroom soup plus a dollop of mayonnaise and a dash of milk since it seemed a little dry. I used white rice made with chicken stock instead of water. Sautéed chicken prior to baking. For seasoning I used garlic powder, a little garlic salt, and cumin. Everyone had seconds and thirds.5 stars

  3. More of a question. Do I cook the chicken before putting it in the casserole ? I’m only 14 and want to surprise my mum

    1. Hi Anne, this recipe calls for cooked chicken so you can cook it beforehand or use pre-cooked chicken from the grocery store. Let us know how it turns out, I’m sure your mom is going to love it!

  4. Made this for dinner tonite. Shared with two neighbors as it made a lot and I’m alone. Very good. may use a bit more spices next time but it was good just the way you wrote it!

  5. I have not tried the recipe yet. It looks and sound great. I would like to substitute whole wheat pasta in this recipe. I am diabetic and even though the carbs in the recipe are just barely within my carb range cutting back a bit would be helpful.5 stars

    1. Absolutely Edith. 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.

  6. I used a cup of sour cream instead of the cream of chicken soup. I added half a can of Mexican style corn with red peppers & red chilies. I also used half a jar of Tostitos queso cheese dip and reduced the shredded cheddar. Extra chili powder, smoked paprika, and cumin. Everyone loved it!!5 stars

  7. My family loves this recipe. It’s always a hit when I make it for dinner. Not difficult and easily eaten as a leftover for lunch the next day :)5 stars

  8. I made this for supper, followed your recipe to the letter and it was delicious, Thank You for sharing it5 stars

  9. Can this be frozen ahead of time? This looks delicious and I want to meal prep before my baby arrives.

    1. I have not personally frozen this recipe but other readers have frozen it after it has baked and fully cooled with good results. I would recommend that your noodles are al dente if you are intending to freeze this casserole.

  10. This was delicious. Such an easy recipe to follow. I used 1 tsp homemade taco seasoning instead of salt and 1 1/2 tsp of chili powder. I added one small can of Mexican Corn (drained) and one can Rotel Tomatoes (drained) My husband loved it!!! Thank you!! This will definitely be a go to recipe for leftover chicken. :)5 stars

  11. Made this for a ski trip (tripled receipe), was delish. Used a lasagna pan and baked longer with good results.
    A keeper for hungry crowds!
    Suggest NOT adding too much salt due to high sodium in canned soup.5 stars

  12. I just made this for dinner tonight. I subbed parm for mozza cause I didn’t have any parm. I really enjoyed this dish. It was easy to make and I like the touch of flavour the chili powder adds. My husband said he wished it was a bit saucier. So maybe I’ll add a touch more milk next time. Thank you. I love so many of your recipes!5 stars

  13. This is a recipe my friend made for me a few weeks after I delivered my baby. I savoured it, it had so much flavour and cheesiness. Now I pass on the favour and have made it for many times for friends. It’s quick and easy and delicious!5 stars
