Creamy Southern Chicken Spaghetti
Creamy Southern Chicken Spaghetti Casserole is the one dish my family most often requests! This easy cheesy pasta dish is the “ultimate comfort food” in the South! You can make in advance and is a great dish to take to potlucks!
This is one of those dishes that tastes even better the next day – so make a big batch so you’ll have some leftovers.
Creamy spaghetti noodles nestled in a cheese sauce with tender chicken and hints of red and green bell peppers! This casserole is ready in less than an hour.
I use real cheddar cheese (no Velveeta) and cream of chicken soup and cream of celery soup. (I know…I don’t usually use canned condensed soups, but for this cheesy chicken spaghetti casserole, I make an exception:)
Here’s what you’ll need
About 2 lbs. of chicken, sharp cheddar cheese, onion, bell pepper (you can use red or green bell peppers), garlic powder, chicken stock (or chicken broth), condensed soups (cream of chicken and cream of celery), sour cream, salt, black ground pepper and spaghetti noodles. See Recipe Card below for exact ingredients and amounts.
You can use any strand pasta you prefer: linguine, fettuccine, or spaghetti. I use thick spaghetti noodles most of the time, but I have made it with flat noodles and it turns out fine.
For best results, I recommend shredding a block of sharp cheddar instead of using pre-shredded cheese.
Here’s how to make Southern chicken spaghetti
This recipe starts out on the stove. Basically, everything is cooked when you put it in the oven-you’re just melting the top layer of cheese in a preheated oven.
If you don’t have time to bake it, you can serve it directly from the stove as well, just add in all the cheese instead of half.
- First, chop the onions, green bell peppers and celery. In a large saucepan on medium heat, add a little oil and saute vegetables for 3-4 minutes, or until tender. Add in the condensed soups, garlic powder, sour cream, one cup of shredded cheddar cheese and chicken broth; let that cook on the stove for about 10 minutes; add in the cooked shredded or cubed chicken and allow to cook on low heat while you make the pasta.
- Bring a large pot of water (salted) to a boil; add pasta and cook according to package directions for al dente pasta – this is usually about 9 minutes. Drain and set aside
- Pour the creamy sauce and chicken into a large casserole dish (9 x 13); add the cooked spaghetti; toss with tongs until the mixture is combined; top with remaining cheese; cover with aluminum foil and bake 15 minutes or until the cheese melts.
Saute vegetables
Add sour cream and condensed soups: NOTE: Generally, I don’t cook with canned condensed soups, but for this classic chicken spaghetti recipe, I make an exception.
Add shredded chicken
Add 1/2 of the cheddar cheese
Pour into lightly oiled baking dish; top with remaining cheese; cover with foil and bake
How to cook the chicken
There are two ways to prepare the chicken for Spaghetti Casserole-you can bake it (recommended method) or broil the chicken
Bake: salt and pepper the chicken and place it in a lightly oiled dish, covered with foil. Bake at 350ºF for about 40-45 minutes, or until the internal temperature reaches 165ºF.
Boil: Bring a big pot of water to high heat, add the chicken and cook about 25 minutes. Again, you want to make sure the temperature of the meat is at least 165ºF.
Even though the baked-method takes a little longer, I prefer it over the boiled-method. Sometimes, boiled chicken turns out rubbery so to avoid a rubber chicken, I opt for the baked-method.
Make ahead: freezer and refrigerator storage instructions
Going to a potluck? You can assemble chicken spaghetti casserole in advance, and store it in either the refrigerator or freezer, either cooked or uncooked. Either of these can be stored in the refrigerator for one day. (Note: uncooked means the pasta is cooked and the dish is assembled, but it hasn’t been baked yet)
If you need to make it more than one day in advance, freeze the casserole.
For uncooked storage, simply assemble the dish and place in an airtight container or cover tightly with plastic wrap. You can refrigerate and freeze until time to serve. Allow uncooked casserole to thaw slightly, then bake in the oven (covered) at 350ºF until it’s bubbly hot.
For cooked chicken spaghetti, place the chicken spaghetti in a secure container and freeze for up to three weeks. When ready to serve, simply remove from freezer and reheat in the oven (covered) at 350ºF or in the microwave.
Cheesy chicken spaghetti casserole is one of those classic American pasta dishes that the whole family loves!

My favorite ❤️
Thank you!
How can we add a little more heat to this recipe? ❤️
Hi Jane!!
Add ground white pepper or cayenne pepper for more heat. You could add chili powder, but that might change the flavor to more of a mexican flair.
This is my favorite!!!
