Ingredients with Measurements (US Cups)

Every great recipe starts with fresh ingredients, and this one is no different. Here’s everything you need to bring this delicious cheesy dream to life:

  • 3 boneless, skinless chicken breasts (about 1.5–2 pounds)

  • 1 can (10 oz) diced tomatoes with green chiles, undrained

  • 1 can (10.5 oz) cream of chicken soup

  • 1 can (10.5 oz) cream of mushroom soup

  • ½ cup diced onion (optional but recommended)

  • 2 teaspoons minced garlic

  • 2 teaspoons Italian seasoning

  • 4 oz cream cheese, cubed

  • 2 cups shredded cheddar cheese

  • 1 package (16 oz) uncooked spaghetti

Optional garnishes:

  • Fresh chopped parsley

  • Red pepper flakes

  • Extra shredded cheese

Step-by-Step Directions

This dish is incredibly easy to prepare, with most of the magic happening inside your slow cooker. Follow these simple steps to make the perfect cheesy chicken spaghetti.

Step 1: Build the Flavor Base in the Crock Pot

Place the chicken breasts directly into the bottom of your crock pot. Pour in the diced tomatoes with green chiles, cream of chicken soup, cream of mushroom soup, onion, garlic, and Italian seasoning. Stir to combine.

Tip: For a stronger tomato flavor, add a tablespoon of tomato paste or an extra half can of diced tomatoes.

Step 2: Let the Slow Cooker Work Its Magic

Cover the slow cooker with the lid and cook on LOW for 6–8 hours or HIGH for 3–4 hours. Avoid lifting the lid during cooking to keep the heat and moisture inside.

Step 3: Shred the Chicken

Once the chicken is fully cooked, remove it and place it on a cutting board. Use two forks to shred it into bite-sized pieces. Return the shredded chicken to the crock pot and stir to mix with the sauce.

Tip: A hand mixer on low can make shredding faster and easier.

Step 4: Add Cream Cheese and Cheddar

Add the cubed cream cheese and shredded cheddar cheese to the crock pot. Stir gently. Cover and cook for another 20–30 minutes on LOW until the cheese is melted and the sauce is smooth.

Step 5: Cook the Spaghetti

While the cheese melts, boil a large pot of salted water. Cook the spaghetti according to the package directions until al dente. Drain well but do not rinse.

Step 6: Combine Pasta and Sauce

Add the cooked spaghetti to the crock pot. Stir thoroughly to coat all the noodles with the creamy chicken and cheese mixture.

Tip: If the sauce is too thick, stir in a splash of chicken broth or milk to loosen it up.

Step 7: Serve

Spoon the cheesy chicken spaghetti into bowls or onto plates. Garnish with chopped parsley, red pepper flakes, or a little extra cheese if desired.

Great side options:

  • Garlic bread

  • Green salad

  • Roasted vegetables

If you prefer a spicy kick, consider these additions:

  • Red pepper flakes

  • Hot sauce

  • Pepper Jack cheese

3. Make It Lighter

Want a healthier version? Try:
