This creamy slow cooker chicken spaghetti is a cozy, family-friendly meal that comes together with simple ingredients and melts into comforting layers of sauce, tender chicken, and cheesy goodness.
This recipe is a winner! It was given to me by a reader named Kierstyn. I tested it and made a few adaptations, and I must say it’s fantastic; it tastes like a mix of marinara and Alfredo. You will love this chicken spaghetti recipe; it’s a fun change from regular crockpot spaghetti sauce.
What You’ll need
These simple ingredients make for a very heavenly spaghetti dinner. The Full Recipe is in the recipe card below the images.
- Cream Cheese + Cream of Chicken Soup – These two combine to create an ultra-creamy, rich sauce that clings perfectly to the noodles.
- Diced Chicken Breasts – Adding the chicken raw and diced means no extra prep later—just stir in the pasta at the end.
- Marinara Sauce – Use a flavorful jarred pasta sauce to save time and still get that classic tomato base.
Cook’s Notes
Don’t add uncooked noodles directly to the slow cooker—the heat isn’t high enough to cook them properly.
If you prefer, you can swap the cream cheese for a cup of heavy cream added just before stirring in the pasta.
Once the cheese has melted, turn off the slow cooker and serve. Avoid leaving it on, as continued heat can affect the sauce’s texture.
Many readers say this recipe is even better when the chicken breasts are left whole and shredded at the end of the cooking time.
Serving Ideas
Round out your plate with these simple sides:
- This creamy chicken spaghetti is even better with a sprinkle of Parmesan and a dash of freshly ground black pepper.
- Add a simple green salad and warm garlic bread to make it a complete meal.
- If you’re serving picky eaters, consider keeping the noodles separate from the sauce.
- Leftovers reheat beautifully—some say they taste even better the next day!

“I love this recipe! It is delicious and makes a ton of food. The leftovers are just as tasty. I like it with the spaghetti noodles and my husband prefers penne pasta It worked great with both options.”

Slow Cooker Creamy Chicken Spaghetti Recipe
How to Video
Ingredients
- 48 oz. spaghetti sauce, (I used 2 jars of Classico Tomato and Basil)
- 21 oz. cream of chicken soup, (2 10.5 oz. cans) do not add water
- 2 tsp. dried oregano
- 2 tsp. dried basil
- 1/2 tsp. garlic powder
- 8 oz. cream cheese,, cubed
- 2 lbs. chicken breast,, diced
- 1 cup shredded mozzarella cheese
- 1 lb. spaghetti, (cooked according to package directions on stove-top)
Instructions
- Add the spaghetti sauce, cream of chicken soup, oregano, basil, garlic powder, cream cheese, and chicken. Stir. The cream cheese will still be in cubes, that is fine.
- Cover and cook on LOW for 6 hours without opening the lid during the cooking time.
- Cook the pasta according to the package directions. Drain well. Add to the sauce and stir. Add the mozzarella cheese on top. Add the lid back on and let the cheese melt, this will only take a few minutes. Serve and enjoy!Note- Kierstyn’s original recipe uses 16 ounces cream cheese and has mozzarella added in the beginning while the sauce cooks. You can make it either way, it will be great!

My family loves this
This recipe was Awesome my family loved it. I don’t understand the comments saying it didn’t have flavor, maybe they didn’t follow the recipe. Everyone has different taste.
Can you cook on high for 4 hours
Yes, that will work fine.
Can I use cream of mushroom instead of chicken?
Yes! I think that would be great.
fairly blah. i will still try again and use a sausage or some other meat. I added quite a bit of red pepper. great that it was a crockpot recipe… but chicken needs something more. my husband and I eat healthy and if I am gonna put all that fat and carbs in a meal, i need a bit more.
Do you think this would taste good with ground turkey?
I think so!
Would the cook time change if you cut the recipe in half?
I would do low for 5 hours.
Boneless chicken only really takes four hours on low to cook throughly
It only gets more tender with time, especially with lots of sauce 🙂
Don’t be afraid to add more seasoning & other items (like vegies) to make this better. I did not add chix soup (cuz yuck), added more oregano, added thyme & savory, fresh hulled peas, sliced zucchini, and SUGAR to cut the bitter salty jarred sauces. Then it was better. The original is a bit bland. Oh, I precooked the chix (actually smoked over a conventional hardwood charcoal grill). Thanks for the basis for a greater recipe.
You changed the whole recipe. Ha it is bland and bitter until you add the chicken soup. Just thought it was interesting you removed ingredients and added more veggies. I don’t like veggies in my spaghetti..
Whats the point in commenting if you didnt even make the dish. You made something completely different and then dissed this recipe
I HATE when people do that! If you’re going to comment, comment on the recipe that was posted.. not your gross-sounding spaghetti with veggies. I also hate when people rate it but didn’t make it.
Lol so change the entire recipe to a new one…? I don’t see the point I thought this recipe was great with a bit less cream cheese. I don’t think it was made to be a super healthy dish
How much is 1 serving?
about 1/10 of the recipe
Is the chicken pre cookek or browned prior to putting into crock pot
no, it’s raw. You can if you would like to though.
Can I leave it for 3 hours on high?
Yes, her original recipe I was on high, she did say you need to stir once or twice, it may stick a bit.
