Add the chicken breasts to your crockpot and season with ranch seasoning, pepper, garlic powder, onion powder, and Italian seasoning.
Add the cream cheese and chicken broth. Cover and cook on HIGH for 3 hours, or until the chicken is fully cooked and tender.
Shred the chicken directly in the crockpot and mix everything together until creamy.
Add the cooked pasta, cheddar cheese, mozzarella cheese, and half-and-half. Stir until everything is well combined.
Sprinkle the crumbled bacon over the top, cover, and let everything sit for 10–15 minutes until the cheese is melted and heated through.
Serve warm and enjoy.
