Best Creamy Chicken Spaghetti is creamy, saucy, comfort food. This easy casserole recipe will quickly become a family favorite!
I think there’s an unwritten rule that you can’t be a food blog unless you have a Chicken Spaghetti recipe. 😉 Therefore, here’s mine.
If you want an easy casserole recipe that your family will love, this is it. You probably already the ingredients for this recipe in your pantry and freezer.
My chicken spaghetti is a little different than a lot of them. I don’t use tomatoes with green chiles (Rotel) instead I use pimentos. Additionally, I use cheddar cheese instead of Velveeta.
Best Creamy Chicken Spaghetti
You have options for the chicken in this recipe. You can boil, broil, or grill the chicken or use leftover chicken or rotisserie chicken. Rotisserie chicken is my go-to for so many recipes. It makes cooking quick and effortless.
One tip, when I boil my chicken, I also boil my pasta in that water, now broth. It just adds a little bit more flavor.
What to serve with Chicken Spaghetti
I like to serve a salad or green vegetable and bread. Pomegranate Broccoli Salad, Sweet and Sour Marinated English Pea and Corn Salad, or Tangy Vinegar Based Slaw are good options. For the bread, We love 10 Minute Rolls, Fluffy Yeast Rolls, or Blue Cheese Biscuits.
Can I freeze Best Creamy Chicken Spaghetti?
Absolutely, it freezes beautifully. Line your dish with parchment paper, pour the chicken spaghetti into the dish, don’t bake it, and cover the casserole dish tightly. Allow it to freeze solid, then remove the parchment paper and casserole and transfer to a large freezer bag. That way you don’t have to tie up your casserole dish for months. The chicken spaghetti is pre-formed for the dish, so all you have to do is slide it back in when you’re ready to reheat. OR, freeze in a disposable casserole dish.
To reheat, cover with foil or oven-safe lid and bake at 375° for 50 to 60 minutes or until hot in the center.

When you say Parmesan cheese do you mean the powder kind in a shaker jar or the fresh you get at the cheese counter?
Paula says
the fresh block – it’s so much better
Sarah says
This a really good recipe, get lots of compliments on the dish. I would use less spaghetti, 16oz is wayyy too much and I’ve also used other types of pasta noodles, whatever I have on hand. I’ll switch up the color of peppers and add black olives. The main ingredients really allows for many different customizations so don’t be afraid to switch things up, depending on the ingredients you have on hand (types of shredded cheese, olives, peppers, noodles…etc.)

Paula says
