Best Creamy Chicken Spaghetti is creamy, saucy, comfort food. This easy casserole recipe will quickly become a family favorite!

Creamy Pimento Chicken Spaghetti

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.

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.

  • Preheat oven to 375°F. Cook spaghetti al dente and drain well.

  • Season with celery seeds, salt, cayenne pepper, and black pepper.
  • Combine spaghetti, chicken, and cream sauce. Mix well. Spread in a greased 9×13 dish. Top with remaining cheddar cheese and bake 25-30 minutes or until hot and bubbly.

    I served it with salad the other night and everybody loved it! Great idea to boil the pasta in that chicken broth, I saw the added flavor. I’ll be making it again for sure.

  2. 5 stars
    This is the best chicken spaghetti recipe I have ever tried. The pimentos and cheese are pure Southern comfort flavors. Thanks for the great recipe. I will definitely be making it again soon.

  3. 5 stars
    Wow, we just made this Creamy Chicken Spaghetti for dinner, and it was a huge hit! The use of pimentos instead of tomatoes added a unique twist! Definitely making this again!+++

  4. 5 stars
    This recipe is comfort food at its finest. The creamy texture and the subtle kick from the pimentos make it a standout. Will make this again for dinner next weekend. Thanks!

  5. When you say Parmesan cheese do you mean the powder kind in a shaker jar or the fresh you get at the cheese counter?

  6. 4 stars
    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.)
