Why I’ll Love This Recipe

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

boneless skinless chicken breasts
minced garlic
kosher salt
fresh cracked black pepper
onion powder
Italian seasoning
cream of chicken soup
diced tomatoes and green chiles (Rotel)
Colby jack cheese (freshly shredded)
cream cheese
spaghetti
fresh chopped parsley (optional garnish)

Directions

Spray a 6–7‑quart slow cooker with nonstick cooking spray or line it with a slow cooker liner.
Place chicken breasts in the cooker and sprinkle with garlic, salt, pepper, onion powder, and Italian seasoning.
In a bowl, whisk together undiluted cream of chicken soup and the diced tomatoes and green chiles (with their liquid).
Pour the soup mixture over the chicken. Cover and cook on high for 4 hours or low for 6 hours.
Remove the chicken, shred it with two forks, and set it aside.
Add the shredded Colby jack and cubed cream cheese to the slow cooker. Cover and cook on high for another 30 minutes until the cheese is fully melted. Stir until smooth.
Meanwhile, cook the spaghetti according to package directions. Drain and rinse with cold water to prevent it from overcooking.
Add the shredded chicken and cooked spaghetti into the slow cooker and stir until the noodles are well coated.
Serve hot, optionally topped with parsley.

Prep time: 10 minutes
Cook time: 4 hours 30 minutes (or up to 6 hours on low)
Total time: approximately 4 hours 40 minutes

Variations

I often customize based on my mood or what I have on hand:

For an ultra-creamy texture, I sometimes swap in cubed Velveeta during the last 20–30 minutes of cooking.
I turn it into a taco-inspired version by adding taco seasoning or ground beef.
For a lighter option, I skip the spaghetti altogether and serve it over zucchini noodles or broccoli slaw.

Storage / reheating

To store: I keep leftovers in an airtight container in the fridge for up to 4 days.
To freeze: I freeze in a freezer-safe container for up to 2 months. Thaw it overnight in the fridge before reheating.
To reheat: I reheat on the stovetop, stirring often until warmed through, or in the oven (9×13 dish, 15–20 minutes), or in the microwave until hot.

FAQs

What type of soup can I substitute for cream of chicken?

I sometimes use cream of celery, onion, or mushroom for a slightly different flavor. Each one works great with the rest of the ingredients.

Can I use chicken thighs instead of breasts?

Absolutely. I’ve used boneless, skinless chicken thighs in place of breasts, and they come out just as flavorful and tender.

How do I prevent the spaghetti from becoming mushy?

I always cook the spaghetti separately, drain it, and rinse it with cold water. That keeps the noodles from getting overcooked when I stir them in later.

Can I make the recipe spicier?

Yes! For more heat, I use hot diced tomatoes and green chiles or add chili powder or red pepper flakes to taste.

What sides go well with this chicken spaghetti?

I like pairing it with a side salad or veggies like sautéed green beans or asparagus. Garlic bread is always a favorite too.

Conclusion

I love how this Crockpot Chicken Spaghetti gives me a comforting, cheesy, and satisfying meal with hardly any effort. With straightforward prep, flexible ingredients, and simple storage options, it’s become a go-to dinner in my home. Whether I’m feeding family or craving something cozy on a chaotic evening, this recipe never disappoints.
