This Slow Cooker Chicken Spaghetti is a fun twist on the classic dish! It features juicy chicken cooked right in the sauce, mixed with noodles and cheese for a creamy treat.
I love how easy this recipe is; just toss in the ingredients, and let the slow cooker do its magic while I kick back. Perfect for busy days or cozy nights! 🍝
Key Ingredients & Substitutions
Chicken Breasts: Boneless, skinless chicken breasts are perfect here for their tenderness. If you prefer, you can use chicken thighs for a juicier option or even rotisserie chicken to save time!
Spaghetti Noodles: Regular spaghetti works best, but you can swap it with whole wheat or gluten-free pasta. Keep in mind that cooking times may vary with different types.
Canned Diced Tomatoes: I love using tomatoes with green chilies for an extra kick! If you’re not into heat, stick to plain diced tomatoes instead.
Soups: Cream of mushroom and cream of chicken provide great flavor. You can use other cream-based soups, like cream of celery, if you have dietary restrictions or preferences.
How Do I Ensure Perfectly Cooked Spaghetti in the Slow Cooker?
Cooking spaghetti in a slow cooker can be tricky, but it’s easy if you follow a few key steps. After shredding the chicken, you’ll want to add the uncooked spaghetti directly to the sauce.
- Break the spaghetti in half before adding to make it easier to fit and cook evenly.
- Make sure the noodles are thoroughly submerged in the sauce to avoid them drying out.
- Cook on high for 30-45 minutes, stirring occasionally to prevent sticking. Keep an eye on the tenderness; you want it al dente!
With these tips, you’ll end up with creamy, delicious chicken spaghetti that everyone will love!

How Much Time Will You Need?
This delicious Slow Cooker Chicken Spaghetti requires about 15 minutes of prep time and between 4-5 hours to cook on low or 2-3 hours on high. Just set it and forget it while the slow cooker does all the work! Perfect for those busy afternoons or lazy evenings.
Step-by-Step Instructions:
1. Prepare the Chicken and Sauce:
Start by placing the chicken breasts at the bottom of your slow cooker. Next, add the diced tomatoes (with their juice), cream of mushroom soup, cream of chicken soup, and the chopped onion on top. Sprinkle in garlic powder, chili powder (if using), salt, and pepper. Gently stir everything together to combine all those yummy flavors!
2. Add the Liquid:
Pour in the chicken broth or water. This will help the chicken cook beautifully and keep everything nice and moist.
3. Cook the Chicken:
Cover the slow cooker and let it work its magic! Cook on low for about 4-5 hours or on high for 2-3 hours. You’ll know it’s done when the chicken is tender and easily shredded.
4. Shred the Chicken:
Once the chicken is cooked, carefully take it out using tongs, and shred it with two forks. It should come apart easily! Now, return the shredded chicken back into the slow cooker to mix it with the sauce.
5. Add the Spaghetti:
Next, break the uncooked spaghetti noodles in half and stir them into the slow cooker, making sure they are all submerged in the sauce. This is where the magic happens!
6. Cook the Spaghetti:
Cover the slow cooker and cook on high for another 30-45 minutes. Check occasionally and stir to make sure the noodles aren’t sticking together. You’ll want them to be tender but not mushy!
7. Mix in the Cheese:
Once the spaghetti is cooked to your liking, add the shredded cheddar cheese. Stir it in until it melts and combines with the sauce, creating a creamy and cheesy dish.
8. Final Touches:
Give it a taste and adjust the seasoning with salt and pepper if needed. Lastly, garnish with fresh parsley or cilantro for a pop of color and flavor before serving.
Enjoy your creamy, cheesy, flavorful chicken spaghetti straight from the slow cooker with minimal effort! It’s perfect for a family dinner or meal prep for the week. Yum!

Yes, you can use frozen chicken breasts! Just make sure to cook on high for an additional hour, and check that the chicken reaches an internal temperature of 165°F before shredding.
What If I Don’t Have Spaghetti Noodles?
No worries! You can substitute with any pasta, such as fusilli or penne. Just adjust the cooking time accordingly, following the package instructions for the specific pasta you choose.
How Can I Make This Recipe Gluten-Free?
To make this dish gluten-free, simply use gluten-free pasta. Ensure all your canned soups are certified gluten-free, and you’re good to go!
Can I Store Leftovers?
Absolutely! Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave, adding a splash of broth if needed to keep it creamy.
