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 chicken and layer in the slow cooker, whisk soup and tomatoes and pour over 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 hot.
Why This Recipe Works
- Layering the chicken and sauce helps the chicken stay moist while the sauce develops deep flavor during the long, slow cook.
- Cooking the pasta separately and rinsing it with cold water prevents overcooking so the noodles stay perfectly al dente when mixed with the sauce.
Slow Cooker Chicken Spaghetti Ingredients
Here’s what you’ll need:
- Boneless skinless chicken breasts: Shreds easily and stays tender after slow cooking.
- Minced garlic: Adds savory depth.
- Kosher salt and fresh cracked black pepper
- Onion powder and Italian seasoning: Simple pantry herbs that boost flavor.
- Cream of chicken soup: Forms the creamy base of the sauce.
- Diced tomatoes with green chiles (Rotel): Adds tang and mild heat.
- Colby Jack cheese and cream cheese: Give the sauce its rich, melty texture.
- Spaghetti: Holds the sauce and ties the dish together.
- Fresh parsley (optional): For garnish.
Substitutions and Additions
Cream of chicken soup: Swap for cream of mushroom or cream of celery for a slightly different base.
Diced tomatoes with green chiles: Use plain diced tomatoes for a milder result or hot diced tomatoes for extra heat.
Colby Jack cheese: Try sharp cheddar or Monterey Jack for a tangier or creamier finish.
How To Make Slow Cooker Chicken Spaghetti
STEP ONE: Spray a 6–7 quart slow cooker with nonstick spray or use a liner for easy cleanup.
STEP TWO: Arrange the chicken breasts in a single layer in the bottom of the slow cooker so they cook evenly.
STEP THREE: Season the chicken with minced garlic, kosher salt, black pepper, onion powder, and Italian seasoning.
STEP FOUR: In a bowl, whisk together two cans (undiluted) of cream of chicken soup and a can of diced tomatoes with green chiles, including the liquid.
STEP FIVE: Spoon the soup-and-tomato mixture evenly over the seasoned chicken so the sauce can infuse the meat as it cooks.
STEP SIX: Cover and cook on low for six hours or on high for four hours. Avoid lifting the lid during cooking to keep heat consistent.
OUR RECIPE DEVELOPER SAYS
Avoid opening the lid during cooking to maintain consistent temperature and timing.
STEP SEVEN: When the chicken is cooked through, remove it to a plate and shred with two forks until bite-sized.
PRO TIP:
Cut into the thickest part to ensure no pink remains before shredding.
STEP EIGHT: Add shredded Colby Jack and cubed softened cream cheese to the slow cooker. Replace the lid and cook on high for about 30 minutes until fully melted, then stir until smooth.
STEP NINE: While the cheese melts, cook the spaghetti in salted boiling water according to package directions until just al dente. Drain and rinse with cold water to stop the cooking and prevent mushy noodles.
STEP TEN: Return the shredded chicken to the slow cooker, add the cooked spaghetti, and stir until the noodles are evenly coated with the creamy sauce. Serve hot, garnished with fresh parsley and a sprinkle of Parmesan if desired.
Troubleshooting
Mushy spaghetti: Cook pasta to al dente, rinse with cold water, and add to the sauce only when ready to serve.
Sauce too thick or too runny: Thin with a splash of chicken broth or reserved pasta water; if too thin, allow the sauce to sit uncovered a few minutes to thicken.
Cream cheese won’t melt: Make sure it’s softened and cubed before adding, then stir after it melts to fully incorporate.
Unevenly shredded or tough chicken: Let the chicken rest briefly, then shred while warm using two forks for consistent pieces.
Cheese clumping: Use freshly shredded cheese instead of pre-shredded to avoid anti-caking agents that can affect melting.
Spaghetti sticking together: Toss drained spaghetti with a little olive oil to keep strands separate before mixing into the sauce.
How To Serve
Pair this dish with simple sides to make a complete meal. Garlic bread, roasted vegetables, or a green salad all complement the creamy pasta nicely. Garnish with chopped parsley and extra grated cheese if you like.
Storage and Make-Ahead
Make ahead: Cook the chicken and sauce, cool, and store in an airtight container in the refrigerator for up to two days. Reheat the sauce and chicken, cook fresh spaghetti, then combine before serving.
Refrigerator: Store leftovers in an airtight container for up to three days. Cool completely before sealing to avoid excess moisture.
Freezer: Freeze cooled sauce and chicken in a freezer-safe container for up to three months. For best texture, freeze sauce and pasta separately.
Reheating: Reheat on the stovetop over medium heat, adding a splash of chicken broth or milk if the sauce tightens. Or microwave in 30-second intervals, stirring between heats to restore creaminess.
