In a large skillet or Dutch oven, cook the chicken pieces until browned and cooked through. Season with salt and pepper.
Add the ranch seasoning mix, chicken broth, and heavy cream to the skillet. Stir to combine.
Bring the mixture to a simmer, then add the pasta. Cook, stirring occasionally, according to pasta package directions, until al dente and the sauce has thickened.
Stir in the shredded cheddar and mozzarella cheeses until melted and the sauce is creamy.
Stir in the crumbled bacon.
Serve immediately, garnished with extra bacon or fresh parsley if desired.
