Add the chicken breasts to the bottom of your crockpot.
Season the chicken with ranch seasoning, garlic powder, onion powder, garlic salt, and black pepper.
Add the minced garlic and block of cream cheese on top of the chicken, then pour the chicken broth around the chicken.
Cover and cook on HIGH for 3 to 4 hours or LOW for 5 to 6 hours, until the chicken is fully cooked and tender.
Shred the chicken directly in the crockpot and mix everything together until the chicken is coated in the creamy ranch sauce.
Stir the heavy cream into the shredded chicken mixture.
Add the cooked pasta, shredded cheddar cheese, and shredded mozzarella cheese. Mix everything together until well combined.
Cover and cook for another 10 to 15 minutes, until the cheese is melted and the pasta is creamy.
Top the entire pasta with 1 pound of cooked, crumbled bacon and serve hot.
