An Easy Casserole

If you like simple, filling and satisfying casseroles, then this chicken spaghetti recipe is for you. Prepping it is easy and even more so if you make it with rotisserie chicken or leftover Oven Baked Chicken Breasts!

Just like a traditional baked spaghetti casserole, the ingredients are basic, and probably staples in your kitchen already. In addition to the chicken, which you need to cook and shred in advance, you just need spaghetti, canned diced tomatoes, broth, cream, and cheeses!

How to Make Chicken Spaghetti

If you are making chicken spaghetti with rotisserie chicken, then there is no need to cook the chicken in advance. Just shred two cups and set aside. If you are cooking from scratch, you can make make Poached Chicken (although I usually have a big batch of crock pot shredded chicken in the freezer for recipes like this).

Then, just follow these simple steps for the best-ever baked chicken spaghetti:

  1. Cook the spaghetti until it is al dente
  2. Make the cream sauce and cook until thick and bubbly. Add in the cheeses (remember to remove the sauce from the heat before adding the cheese).
  3. Stir in the pasta, chicken and tomatoes and place in a greased casserole dish.
  4. Top with more cheese and bake until bubbly!

Allow your baked chicken spaghetti to rest for five minutes to firm up.

Short Cut Chicken Spaghetti Sauce

Short on time? Make a Short Cut Chicken Spaghetti Recipe! Try it with canned cream of mushroom soup, and a can or two of Rotel tomatoes instead! It will still be tasty and satisfying. Be sure to buy the rotel without lime added!

Here’s a quick and easy shortcut sauce for chicken spaghetti:

  • Sautee peppers and onions.
  • Add in one can of cream of mushroom soup and 3/4 pound diced processed cheese (like Velveeta). Heat until melted and creamy.
  • Season with onion and garlic powders and pepper (the Velveeta and soup have plenty of salt already, so you may not need to add any.)
  • Continue as directed in the recipe.

Now all that’s left is to bake and enjoy!

What to Serve With Spaghetti Casserole: Serve up whatever your favorites to go along with an Easy Lasagna or Cheesy Chicken Casserole are. For us that usually means a fresh green salad (or kale salad) and some dinner rolls or biscuits.

Can You Freeze Chicken Spaghetti? Chicken spaghetti freezes exceptionally well, so go ahead and make it in advance. Once you place it in the casserole dish, you don’t need to bake it first, just freeze for up to four months.

Here’s a little trick: Line your dish with parchment paper and let it freeze solid, then transfer to a large freezer bag. That way you don’t have to tie up your casserole dish for months. The chicken spaghetti is already pre-formed for the dish, so all you have to do is slide it back in when you’re ready to reheat.

You can cook this directly from frozen (but be careful, most glass dishes cannot go from freezer to oven). Cover it in foil to prevent the cheese topping from overcooking. Cook at 375°F for about an hour, or until it is piping hot throughout!

Baked chicken spaghetti is rich and super filling. It doesn’t need many fussy side dishes. I like to serve it with bread sticks or garlic bread, and a cucumber salad or fresh green salad dressed with vinaigrette for some color and crunch.

  1. Delicious!! I made this recipe for the first time to take to our church luncheon and it was a big hit with everyone, including my husband and myself. My neighbor asked for the recipe, she said it was a “keeper”. I plan on making it again soon.
    Can’t wait to look through the rest of your recipes

  2. Absolutely delish! I used semi-sun dried and some cherry tomatoes from my garden. Left out the peppers and onions so my old dog could have some. Loved by all!

  3. This recipe never yells too where to add the garlic. Being a seasoned cook of course I put it in with the peppers and onions. Just a note for the inexperienced cook. Was so delicious though.

  4. Thanks for a recipe that doesn’t have any “Cream of …” soup. Too much salt! We are discovering that we can live without salt – and my husband lost 100 pounds!

    1. So glad you have enjoyed this recipe Carol! Congratulations to your husband on his weight loss and to you on cutting the salt!

  5. My Blue Apron delivery was late so I had to pull dinner together last night with what was in my pantry and refrigerator. With some leftover rotisserie chicken from Costco this meal was a hit! I will give our elderly mothers the leftovers today. I used cream of chicken soup rather than make the sauce from scratch and whole milk instead of light cream. Also used a variety of cheeses (provolone, parmesan, and Grated Mexican Cheese mix) I had available . The Italian spices I used were oregano, marjoram and basil with a few good shakes of red pepper flakes and white pepper. Will definitely make this again. Great way to use leftover chicken.

  6. Sooo yummy! I omitted the tomatoes and accidentally left out the Italian seasoning, and it was still great! Will make again!

  7. I just made this a couple of days ago and we love it ! This is a keeper and one I will make again and again. My husband was surprised with ‘chicken spaghetti’ but loved it. Thanks.

    1. Light cream has a lower percentage of fat than heavy or whipping cream but can still be found in the dairy section of most grocery stores. Hope that helps Irma!

  8. I made this for dinner last night. My 4 & 6 year olds gobbled it up and my 4 year old said today “mommy, I really like that pasta you made”. My husband and I added a little more Italian seasoning and garlic to ours. It was creamy and delicious.

  9. My husband and I love this dish! he says it’s his new favorite so I’ll obviously be making it again. Thank you!

  10. I would like to have a copy of the pineapple salmon recipe. I couldn’t find any way to copy it. Any chance of printing it so I can use it?

    1. Hi Dixie,
      Right above the ingredient list there are two blue boxes, If you click the first one it will print. I hope this helps!

  11. Looks delicousis will be using receipe I have Gout this would be allowed in small portions thank you for new ideas using chicken !!

    1. Thanks Daniela! It was hard to resist long enough to photograph! It really is as delicious as it sounds!

  15. My child is going to love this! Great idea. Never hear of a spaghetti casserole before. Will swap cheddar for velvet as we don’t fancy the taste of American processed cheese.

  16. The first time I had chicken spaghetti was when i was dating my husband and I loved it. This looks like a great recipe.

  17. Love your little trick about the parchment paper!! I can’t even begin to tell you how WONDERFUL this recipe looks! My kids will love this! Printing now so I can make it this week. So glad I found this recipe!!

  18. This looks like comfort food in a pan! I love having a few great casseroles like this in my back pocket for meal prep because they always reheat so well. This one is ultra-creamy looking!

  19. This is SO good! Recommend half a cup less cheddar, a little more of the italian seasoning, and more bell peppers. This would honestly probably be just as good with spinach too!

  20. I could have this all day, every day!! This homemade spaghetti looks perfectly well made with simple flavors and the perfect texture. Thanks for sharing !!

  21. What an excellent idea adding chicken to a spaghetti casserole dish! I would have never thought of it, but I bet my family would love it! It looks soooo creamy and delicious :P

  22. Wow! This spaghetti dish looks so delicious. It’s everything I love in a dish, creamy, cheesy and flavorful! It looks perfect!

  23. Ooh this looks so good. And thank you for the tip on how to freeze it! When cooking for two, that means there is always leftovers but I never know how to freeze it easily. Can’t wait to try :)

  24. This definitely looks like a dish that could become a family favourite! Noodles are never a bad idea in my house, we all love them. This looks so comforting and delicious!

  25. Hi Holly, can’t wait to try this recipe, but the instructions don’t say when to add the chicken. I’m assuming when you mix everything together before baking?
