What kind of chicken should I use?
For most casserole recipes, I like to use shredded chicken. Any kind works great – try leftover chicken, rotisserie chicken (wonderfully quick!), or even canned chicken.
If you prefer to use diced chicken, fully cook the breasts or thighs before dicing and combining with the rest of the ingredients.
Can I make this casserole ahead of time?
Yes! Prepare this casserole through step 5. Keep it covered in the refrigerator for up to 24 hours until ready to bake and serve.
Keep leftovers in an airtight container in the refrigerator for 3 days. Reheat in the oven at 350°F for 20 minutes, or until warmed through, or heat smaller portions in the microwave.
What should I serve with chicken casserole?
While delicious and filling on it’s own, serve a fresh side salad, roasted vegetables, or warm crusty bread with this cheesy chicken casserole.


Recipe Tips and Notes
- Rotisserie chicken works wonderfully for this recipe. Instead of rotisserie chicken, try leftover grilled chicken or canned chicken.
- Instead of cream of mushroom soup, use cream of chicken soup for a slightly different flavor.
- Try adding additional veggies like celery or cauliflower to this casserole – they practically disappear!

Warm and comforting cheesy chicken spaghetti casserole is so simple to make and will quickly become a family favorite!

Great recipe but a little confusing. Decide into 3 parts. 1. Cheese and wet ingredients 2. Chicken, veggies and spices. 3. Pasta. Mix ingredients then combine with pasta and place in casserole pan and top with parma. Follow cooking times and all should be well. very twisty kids loved it. I substituted retell for cayenne and part of the broth.

Hi John, I’m sorry this recipe was a bit confusing for you! I tried to organize it so that you could complete other steps while the pasta is cooking to cut own on the total time the recipe takes. I’m glad it was a hit!
