Ingredients

For this delicious Crock Pot Chicken Spaghetti Recipe, you’ll need:

• 1½ pounds (680g) boneless, skinless chicken breasts
• 8 ounces (225g) spaghetti, broken into thirds
• 1 can (10.5 oz/298g) cream of chicken soup
• 1 can (10 oz/283g) diced tomatoes with green chilies, undrained
• 1 medium bell pepper, diced (about 1 cup/150g)
• 1 medium onion, finely chopped (about 1 cup/160g)
• 2 cups (8 oz/225g) shredded cheddar cheese, divided
• 1 cup (240ml) chicken broth
• 2 teaspoons Italian seasoning
• 2 cloves garlic, minced
• ½ teaspoon salt
• ¼ teaspoon black pepper
• 2 tablespoons butter

The chicken breasts serve as the protein foundation, becoming tender and shreddable during the slow cooking process. Use regular spaghetti for this recipe as whole wheat varieties might not hold up as well in the slow cooker. The combination of cream of chicken soup and diced tomatoes creates that signature creamy tomato base that makes chicken spaghetti so irresistible.

Pro Tips

Choose the right pasta cooking time: The trickiest part of slow cooker pasta dishes is getting the pasta perfectly cooked. For this Crock Pot Chicken Spaghetti Recipe, add the pasta during the last 30-40 minutes of cooking time rather than at the beginning. This prevents the spaghetti from becoming mushy while still allowing it to absorb all those delicious flavors. Test a strand at the 30-minute mark—it should be al dente with a slight bite.

Prep for maximum flavor development: To elevate the taste profile, spend an extra 5 minutes sautéing the onions, bell peppers, and garlic before adding them to the slow cooker. This quick step caramelizes the vegetables, releasing their natural sugars and creating deeper flavor dimensions that simply can’t be achieved by raw ingredients alone.

Perfect your cheese incorporation: Instead of adding all the cheese at once, use a two-stage approach. Mix half the cheese into the hot pasta mixture where it will melt into a creamy sauce, then sprinkle the remaining cheese on top and cover for 5-10 minutes until melted. This technique creates distinct layers of cheese flavor and that coveted stretchy, Instagram-worthy cheese pull when serving.

Instructions

Step 1: Prepare the chicken and base
Place the chicken breasts in the bottom of a 6-quart slow cooker. In a medium bowl, mix together the cream of chicken soup, diced tomatoes with green chilies, chicken broth, Italian seasoning, salt, and pepper. Whisk until well combined, then pour this mixture over the chicken. Add the diced bell peppers, onions, and minced garlic, distributing them evenly throughout the liquid.

Step 2: Set your cooking time
Cover the slow cooker and cook on LOW for 5-6 hours or on HIGH for 3-4 hours, until the chicken is tender enough to shred easily with two forks. The chicken should reach an internal temperature of 165°F (74°C) to ensure it’s fully cooked.

Step 3: Shred the chicken
About 45 minutes before serving, remove the chicken from the slow cooker and place it on a cutting board. Using two forks, shred the chicken into bite-sized pieces. The meat should pull apart effortlessly—a sign it’s perfectly cooked! Return the shredded chicken to the slow cooker and stir to combine with the sauce.

Step 4: Cook the pasta
Break the dry spaghetti into thirds (this makes it easier to stir and serve later) and add it to the slow cooker, pushing it down to submerge in the liquid. Add the butter, which will help prevent the pasta from sticking together. Cover and cook for an additional 30-40 minutes on HIGH, stirring halfway through, until the pasta is tender but still has a slight bite.

Step 5: Add cheese and serve
Once the pasta is cooked to al dente, stir in 1 cup of the shredded cheddar cheese until fully incorporated into the sauce. Sprinkle the remaining cup of cheese over the top, cover, and cook for another 5-10 minutes until melted. Give your Crock Pot Chicken Spaghetti one final stir before serving, making sure the creamy sauce evenly coats all the spaghetti and chicken. Garnish with fresh parsley if desired for a pop of color!

Variations

Spicy Southwestern Chicken Spaghetti: Transform this Crock Pot Chicken Spaghetti Recipe into a zesty southwestern delight by adding 1 tablespoon of taco seasoning, substituting pepper jack for cheddar cheese, and stirring in ½ cup of corn kernels and ½ cup of black beans during the last hour of cooking. Top with sliced avocado, chopped cilantro, and a squeeze of lime juice before serving for a Mexican-inspired twist that adds both flavor and visual appeal.

Vegetable-Packed Version: Make this comfort food more nutritious by incorporating additional vegetables. Add 2 cups of baby spinach, 1 cup of sliced mushrooms, and 1 grated zucchini during the last hour of cooking. The vegetables will soften while maintaining their integrity and boost the nutritional profile without sacrificing the creamy, comforting nature of the dish. This variation is perfect for sneaking extra vegetables into kids’ diets or creating a more balanced one-pot meal.

Gluten-Free Option: This slow cooker chicken spaghetti can be easily adapted for those with gluten sensitivities. Simply substitute the regular spaghetti with your favorite gluten-free pasta (corn and rice blends work best), and ensure your cream of chicken soup is gluten-free. Be sure to check the pasta at the 20-minute mark as gluten-free varieties often cook more quickly and can become mushy if overcooked.

Storage and Serving

Your Crock Pot Chicken Spaghetti Recipe keeps beautifully, making it perfect for meal prep. Store leftovers in airtight containers in the refrigerator for up to 4 days. When reheating, add a splash of chicken broth or milk to revive the creamy texture that may thicken during storage. For longer preservation, freeze portions in freezer-safe containers for up to 3 months—just thaw overnight in the refrigerator before reheating.

For a complete meal, serve this cheesy chicken spaghetti with garlic bread to soak up the delicious sauce. A simple side salad with a light vinaigrette provides a refreshing contrast to the rich, creamy pasta. For a more substantial spread, pair it with roasted broccoli or asparagus tossed with olive oil, salt, and pepper—the charred edges of the vegetables complement the creamy pasta perfectly.

For an elegant presentation, transfer the finished Crock Pot Chicken Spaghetti to a large serving bowl, garnish with fresh herbs like parsley or basil, and offer extra grated parmesan at the table for guests to customize their portions to taste.

FAQs

Can I use frozen chicken for this Crock Pot Chicken Spaghetti Recipe?
For food safety reasons, it’s best to use thawed chicken. Frozen chicken may spend too long in the temperature danger zone (40°F-140°F) when cooked in a slow cooker, potentially allowing bacteria to grow.

Why did my pasta turn out mushy?
Pasta likely cooked too long. Remember to add the spaghetti only during the final 30-40 minutes of cooking time and check it at the 30-minute mark for al dente texture.

Can I make this dish ahead of time?
Yes! Prepare everything except the pasta and cheese. Refrigerate the chicken-sauce mixture for up to 24 hours, then reheat in the slow cooker, add pasta and cheese according to instructions.

What can I substitute for cream of chicken soup?
Make a homemade version by whisking 3 tablespoons of butter with 3 tablespoons of flour, then slowly adding 1 cup of chicken broth and ½ cup of milk, cooking until thickened.

Is this slow cooker chicken spaghetti freezer-friendly?
Yes, but freeze before adding pasta. When ready to use, thaw overnight in the refrigerator, heat in the slow cooker, and add fresh pasta during the final cooking stage for best texture.
