What You Need To Know
- Main ingredients: Boneless skinless chicken breasts, cream of chicken soup, diced tomatoes with green chiles, Colby Jack cheese, cream cheese, spaghetti, Italian seasoning, and minced garlic.
- Quick steps: Season the chicken and place it in the slow cooker. Whisk soup and tomatoes together and pour over the chicken. Cook on low for six hours or high for four. Shred the chicken, add cheeses and melt, then toss with cooked spaghetti and serve.
Why This Recipe
- Layering the chicken and sauce ingredients helps keep the chicken moist while allowing the sauce to develop deep, balanced flavor.
- Cooking the pasta separately and rinsing it with cold water prevents overcooking and keeps the noodles pleasantly al dente when mixed with the sauce.
Slow Cooker Chicken Spaghetti Ingredients
You’ll need the following:
- Boneless skinless chicken breasts: Shreds easily after slow cooking.
- Minced garlic: For savory depth.
- Kosher salt and fresh cracked black pepper
- Onion powder and Italian seasoning: Simple seasonings to boost flavor.
- Cream of chicken soup: Creates the creamy base.
- Diced tomatoes with green chiles (Rotel-style): Adds tang and a mild kick.
- Freshly shredded Colby Jack cheese: Melts smoothly into the sauce.
- Cream cheese: Adds richness and a silky texture.
- Spaghetti: The pasta that soaks up the sauce.
- Fresh parsley (optional): For garnish.
Substitutions and Additions
Cream soup: Swap cream of chicken for cream of mushroom or cream of celery if desired.
Diced tomatoes: Use plain diced tomatoes for a milder version, or fire-roasted/hot diced tomatoes for more heat.
Cheese: Sharp cheddar or Monterey Jack work well instead of Colby Jack for different flavor profiles.
How To Make Slow Cooker Chicken Spaghetti
Step 1: Spray a 6–7 quart slow cooker with nonstick spray or use a disposable liner for easy cleanup.
Step 2: Lay the chicken breasts in a single layer in the bottom of the slow cooker so they cook evenly.
Step 3: Sprinkle the chicken with minced garlic, kosher salt, black pepper, onion powder, and Italian seasoning.
Step 4: In a bowl, whisk together the undiluted cream of chicken soup and the can of diced tomatoes with green chiles, including the liquid.
Step 5: Spoon the sauce evenly over the seasoned chicken so it seeps in as it cooks.
Step 6: Cook on low for six hours or high for four hours. Avoid lifting the lid during cooking to keep the temperature steady.
Step 7: When the chicken is fully cooked, remove it and shred with two forks while warm.
Step 8: Add shredded Colby Jack and cubed, softened cream cheese to the sauce. Cover and cook on high for another 30 minutes, then stir until smooth and fully combined.
Step 9: While the cheese melts, cook the spaghetti in well-salted boiling water to al dente, drain, and rinse with cold water to stop cooking and prevent mushiness.
Step 10: Return the shredded chicken to the slow cooker, add the cooked spaghetti, and stir until the noodles are fully coated. Serve hot, garnished with fresh parsley and a sprinkle of Parmesan if you like.
Troubleshooting
Mushy spaghetti: Cook pasta to al dente, rinse with cold water, and mix into the sauce just before serving.
Sauce too thick or thin: Thin with a splash of chicken broth or reserved pasta water. To thicken, simmer uncovered a few minutes before adding pasta.
Cream cheese won’t melt: Use softened, cubed cream cheese and stir well after melting to incorporate it into the sauce.
Uneven chicken shredding: Let cooked chicken rest for a few minutes, then shred while still warm using two forks for even pieces.
Cheese clumps: Use freshly shredded cheese rather than pre-shredded, which can contain anti-caking agents that affect melting.
Pasta sticking together: Toss drained spaghetti with a little olive oil if you need to hold it before mixing with the sauce.
How To Serve
Turn this dish into a full meal with simple sides that complement the creamy spaghetti:
- Garlic bread: Crunchy, buttery garlic bread pairs perfectly with creamy pasta.
- Simple salad: A crisp green salad with a tangy vinaigrette adds freshness and balance.
- Roasted vegetables: Roasted carrots, zucchini, or broccoli add color and nutrition.
How To Store
Make ahead: Cook the chicken and sauce, cool, and store in an airtight container in the fridge for up to two days. Reheat, cook spaghetti fresh, and combine before serving.
Refrigerator: Store leftovers in an airtight container for up to three days. Cool completely before refrigerating to reduce excess moisture.
Freezer: Freeze in airtight containers or bags for up to three months. For best texture, freeze the sauce and chicken separately from the pasta.
Reheating:
- Stovetop: Reheat over medium heat, stirring occasionally. Add a splash of chicken broth or milk to loosen the sauce if needed.
- Microwave: Heat in 30-second intervals, stirring between each, until warmed through.
