Cover and cook: Add the lid to the top and cook on HIGH for 3-4 hours or on LOW for 6-8 hours.

Shred the chicken: Remove the cooked chicken breast from the crock pot using tongs. Shred with two forks, then add it back to the crock pot along with the sour cream and cheddar cheese. Stir well, then cover and continue to cook for an additional 30 minutes.

Cook spaghetti: While cheese and sour cream are melting, cook spaghetti noodles according to the package direction to al dente. Then drain and stir into chicken and sauce. Serve while hot, and enjoy!

  • To save time, you can use pre-shredded rotisserie chicken instead of cooking and shredding the chicken yourself.
  • If you prefer a milder version of this dish, you can use diced tomatoes instead of Rotel tomatoes with green chilies.
  • For a lighter version of this dish, you can use low-fat cream of mushroom soup and reduced-fat cheddar cheese. You can also use whole wheat or gluten-free spaghetti noodles.
  • If the sauce is too thick, you can add a little bit of chicken broth or water to thin it out to your desired consistency. If the sauce is too thin, you can let it cook for a bit longer to thicken up.



  • If you're a fan of spice, you can add a diced jalape√Īo pepper or a pinch of cayenne pepper to the dish for an extra kick.
  • For a vegetarian version, substitute the chicken with your favorite vegetables, such as mushrooms, zucchini, or eggplant.
  • Use a different type of cheese to change the flavor of the dish. Use mozzarella cheese for a milder flavor or pepper jack cheese for a spicier kick.
  • For a smoky and salty flavor, add cooked bacon or diced ham to the crock pot with the other ingredients.
  • Use gluten-free spaghetti noodles or substitute the pasta with zucchini noodles or spaghetti squash for a gluten free or low carb pasta dish.


Storing: To store leftover chicken spaghetti, transfer it to an airtight container and store it in the refrigerator for up to 4 days. You can reheat the pasta in the microwave or on the stove, adding a splash of milk or chicken broth to thin out the sauce if needed.
