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!

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.

  • 2 lbs chicken boneless, skinless

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.
