The thing is, this Crockpot Chicken Spaghetti hits all the right notes. It’s so easy to prepare—you just toss everything into the slow cooker and let it work its magic.

Ingredients

1½ pound boneless skinless chicken breasts
1 tablespoon minced garlic
1½ teaspoon kosher salt
1 teaspoon fresh cracked black pepper
1 teaspoon onion powder
1 teaspoon Italian seasoning
21 ounces undiluted cream of chicken soup (2 cans)
10 ounces diced tomatoes and green chiles
2 cups freshly shredded Colby Jack cheese
4 ounces softened and cubed cream cheese
16 ounces package spaghetti
1 teaspoon fresh chopped parsley (optional garnish)

Step-by-step instructions

Spray a 6-7 quart slow cooker with nonstick cooking spray, or line with a slow cooker disposable liner.
Lay the chicken breasts in a single layer in the bottom of the slow cooker.
Evenly sprinkle the minced garlic, kosher salt, pepper, onion powder, and Italian seasoning over the chicken breasts.
In a small bowl, whisk together the undiluted soup and the diced tomatoes and green chiles with liquid.
Spoon the soup mixture over the seasoned chicken. Place the lid on the slow cooker and cook on high for 4 hours or low for 6 hours.
After cooking, check that the chicken is completely cooked. Remove the chicken to a plate or bowl and shred it using 2 forks.
Add the shredded Colby Jack cheese and cubed softened cream cheese. Replace the lid and cook on high for another 30 minutes. Remove the lid and check that the cheese is fully melted before stirring together.
While the cheese is melting in the slow cooker, cook the spaghetti according to package instructions. Drain and rinse with cold water.
Add the shredded chicken and cooked spaghetti to the slow cooker, and stir to combine and coat the noodles. Serve hot.

Recipe tips & variations

Here’s something I discovered after making this a bunch of times: adding the cream cheese once the chicken is cooked makes it extra creamy and rich. For a flavor twist, throw in some red pepper flakes or a can of sliced mushrooms. And if you're on a tight schedule, prepping the night before works wonders!

Storage & reheating

To store, place any leftovers in an airtight container in the fridge for up to three days. Reheating is simple—just pop it in the microwave or on the stovetop over medium heat until warmed through. It’s also freezer-friendly, so don’t hesitate to double the batch!

FAQs

Can I cook the spaghetti directly in the slow cooker instead of boiling it separately?

Yes, but I find that boiling it separately avoids mushy noodles and keeps the texture just right.

Can I make slow cooker chicken spaghetti ahead of time and reheat it later?

Absolutely! It reheats beautifully. Just store it properly, and it’ll be just as delicious the next day.

What is the best cheese to use for creamy slow cooker chicken spaghetti?

Colby Jack is my go-to for its melt quality and flavor, but a mix of cheddar and mozzarella works wonders too.

How do I keep chicken spaghetti from getting mushy in the crockpot?

Boiling the spaghetti separately and keeping an eye on the consistency of the chicken and sauce is key. Stir gently to maintain the texture.
