Add the chicken breasts to your crockpot.
Season the chicken with garlic salt, black pepper, garlic powder, onion powder, and Kinder's Buttery Garlic & Herb seasoning.
Pour in half a jar of Sweet Baby Ray's Garlic Parmesan Sauce, then add the cream cheese and milk.
Cover and cook on HIGH for 3 hours, or until the chicken is fully cooked and shreds easily.
Remove the chicken from the crockpot and shred it with two forks.
Return the shredded chicken to the crockpot and stir until the sauce is smooth and well combined.
Add the cooked pasta and the entire bag of shredded Parmesan cheese to the crockpot.
Mix everything together until the pasta is evenly coated and the Parmesan cheese has melted into the sauce.
Serve hot and enjoy.
