If you’re looking for a dish that will not only satisfy the kids, but the adults, too, this is your casserole!

This dish makes quite a bit. But, it also freezes beautifully. Whenever we make it, we put it into two 8″x8″ pans and bake one and freeze the other. This is cheesy, yummy goodness. Serve it with green beans and crescent rolls for the perfect weeknight dinner!

As mentioned, this chicken spaghetti recipe is easy to prepare and can also be adapted to individual tastes.

If you don’t have time to sauté the onions and celery, just leave them out!

This is a perfect weeknight meal!

Preparing the Chicken

We love simmering 2 lbs of boneless skinless chicken breast in water to cook the chicken.

Simply bring about 8 cups of water to a boil, and then place the chicken into the water. Cover and reduce the heat to medium-low for another 25 minutes. Drain, and once cool enough to handle, cube the meat.

EXPERT TIP: We save the water that we cooked the chicken in to boil our pasta. Be sure to save about 1 cup of the pasta water. You’ll need to thin the sauce a bit a little later on. NOTE: To make life even easier, pick up a rotisserie chicken from the grocery store and cut away the meat!

The Ingredients You Will Need

After cooking the chicken and pasta, it’s time to bring together the amazing sauce.

Here are what we like to use, but you can go with whatever you have on hand:

For the sauce:

  • Butter
  • Chopped onion
  • Chopped celery
  • Cream of mushroom soup
  • Cream of chicken soup
  • Ro-tel (canned chopped tomatoes with green chiles)
  • Velveeta
  • Cream cheese
  • Salt and pepper

EXPERT TIP: Ro-tel is a Southern staple. It carries a bit of heat with it. If you prefer no spice whatsoever, then just go with chopped tomatoes, either canned (drained) or fresh. Ro-tel can be found in the canned tomatoes sections of most well-stocked supermarkets. If you can’t find Ro-tel, other brands carry a similar product.

Add all of the ingredients to your large pot, and cook over medium-low heat until the cheese has completely melted. We added anywhere from ½ to 1 cup of the reserved liquid to the sauce. If you like an extra thick sauce, don’t add any additional liquid.

A large Dutch oven pot filled with cubed cream cheese, Velveeta, creamed soups, chopped tomatoes, salt, and pepper, and then the same pot after the cheese has melted and everything is stirred together.

Once the sauce comes together, it’s time to dump in the cooked pasta and chicken.

If your pot isn’t big enough, you may need to transfer everything to a large bowl.

Stir until completely mixed together.

FAQs Chicken Spaghetti

  • Can it be made ahead? – Absolutely! This is an amazing dish that can 100% be made in advance. Assemble the casserole but don’t bake it. It can stay, covered, in the fridge for 3 or 4 days. If freezes perfectly, too, for up to 2 months. Let thaw before baking. Leftovers can be reheated in a 350°F oven for about 20 minutes, covered. NOTE: The casserole isn’t as creamy when reheated because the spaghetti will absorb some of the liquid.
  • I don’t like onions, can they be left out? Of course! So can the celery. If you’re in a pinch for time and don’t have time to sauté the veggies, just add a little onion powder and celery salt to the sauce. If adding celery salt, be sure to cut back on regular salt, too, otherwise, the casserole will be too salty.
  • Could ground beef replace the chicken? You bet! Brown the beef, drain the grease, and then season with a healthy pinch of salt and pepper. If you want a vegetarian version, stir in steamed veggies in place of the protein. Yum!

We love using a lasagna pan for baking the chicken spaghetti, but a 9″x13″ dish will work, too.

The addition of cheese on the top of the casserole isn’t completely necessary.

But why not.

Spaghetti Chicken is cheesy. Which is one of the reasons it’s so delicious!

When To Serve

This dish is such a family favorite, and is so easy to put together, it’s really the perfect weeknight meal.

It’s also an ideal dish to bring to a potluck dinner or as a gift to anyone wants a good home-cooked meal, but isn’t in the mood to cook.

Remember, you can easily freeze half of the dish and then simply bake later on when you’re really crunched for time.

Wow, is this good!

We love casseroles because they are so comforting, can often be made in advance, and are almost always such a hit with the entire family.

Equipment

  • Lasagna pan, or 9"x13" dish, or two 8"x8" pans

Ingredients

  • 2 lbs chicken boneless, skinless
  • 1 lb spaghetti dried
  • 2 tablespoon unsalted butter or olive oil
  • 1 cup onion chopped
  • 1 cup celery chopped
  • 1 can Ro-tel don't drain
  • 1 10.75 oz cream of mushroom soup canned
  • 1 10.75 oz cream of chicken soup canned
  • 16 oz Velveeta cubed
  • 8 oz cream cheese cubed
  • 2 teaspoon Kosher salt
  • 1 teaspoon black pepper freshly ground
  • 1 cup cheddar cheese shredded

Instructions

  • Bring a large pot of water to a boil (about 8 cups of water). Add the chicken breasts, cover the pot, and lower the heat to medium-low. Cook for 25 minutes.
  • Carefully remove the chicken from the water and let it cool on a rack or cutting board. When cool enough to handle, cut the chicken into bite-sized pieces. Set aside. Leave the water in the pot.
  • Preheat oven to 375°F.
  • Bring the chicken broth to a boil again and add the spaghetti. Cook until al dente, usually about 9 minutes. Drain and set aside. Remove about 1 cup of the chicken/pasta water and keep for making the sauce.
  • Pour out the liquid and place the pot over medium-high heat. Melt the butter and then add the onions and celery and cook, stirring often, until soft, about 4 to 5 minutes.
  • To the pot, add the Ro-tel, both soups, Velveeta, cream cheese, salt, and pepper. Stir frequently until the cheese has melted and everything is combined. Add about ¾ of the reserved pasta water. Stir to incorporate. Stir in the cooked chicken and spaghetti. Stir until fully mixed.
  • Transfer to lasagna, or baking, dish. Top with the grated cheese and then bake for 25 minutes, until the cheese has completely melted and the casserole is bubbly. Remove from oven and let rest for 5 to 10 minutes.

Notes

See our "How To Prepare Chicken Spaghetti Recipe" near the top of the blog post.  If you like the video, please subscribe to our YouTube Channel. 
You can use chicken from a rotisserie chicken for this dish.  1 chicken is usually enough, but you can certainly go with 2.  
Substitute any kind of cream soup, if desired.  
We often split this recipe into 2 batches.  Each batch goes into an 8"x8" pan.  We bake one a freeze the other.  When we're ready to bake the frozen batch, we let it thaw completely, and then bake for 25 to 30 minutes.

    This was delicious! The Griffen declared it the best, using the word “excellent.” It’s absolutely wonderful. Thank you so much for another fantastic recipe. 100% Griffen Approved! I would like to add some crunch to it. Do you think some corn flakes, club crackers, or croutons on top would work? Do you have any suggestions to add a little crunch? Can you just throw the crunch on before baking, or should you bake it for a while and then add the crunch on top? I love how versatile this recipe is, just by changing the flavor of Rotel, or the different kinds of soup or Velveeta, although The Griffen says it is perfect just the way it is and he thinks we need to serve it to our friends! Look at me! You guys are making me a chef!

      Hi Michelle! You are a rock star in the kitchen! You could add some crushed corn flakes on top, or even Panko breadcrumbs (mix with a little melted butter) for a wonderful crunchy topping. That would be delicious!!! You ARE a chef!!!! xoxo

    I LOVE reading your recipes, and this one sounds delish! I was wondering what you thought about trading the spaghetti for spaghetti squash. What do you think? Would it work?

    Loved this! Have been looking forward to making it since it was posted. Took the easy way out and cut up the chicken breasts from two rotisserie chickens. Combined 4 cups of chicken stock with 4 cups of water, brought to a boil for spaghetti. Baked the whole batch in a 9×13 casserole dish. Delicious, but very filling!! No worries … lots of leftovers! Next time (and my family tells me there WILL be a next time!), I’ll do as you recommended, split it, go with two 8×8” dishes and freeze one.

    I’ll say it again … delicious!

      Hi Mark!! That is SO AWESOME!! Rotisserie chickens are a great way to go! You are so correct! It does make a lot, and it is quite filling. Splitting and freezing one is a great option, too. Thank you SO MUCH as always for letting us know how it went and for the wonderful review! You and your family mean so much to us!!! Kris & Wesley

    I was yearning to make something fun and easy that brings about a colossal amount of guilt upon eating. 😉 My husband and I enjoyed this! I used fusilli because it’s all we stock in our pantry, but other than that, didn’t change a thing. Great comfort food. Thank you for the recipe and fun vid. 🙂

    So surprised you’re using canned “cream of” soups when most of your casseroles have a sauce from scratch.

      Hi Jane! We are providing a wider variety of recipes. We love making everything from scratch, but sometimes, on a busy weeknight, opening a can does the trick! LOL! The results are still yummy! Don’t worry, we’ll still deliver lots of recipes where everything is homemade!! Thanks, Kris & Wesley
