Prepare the Pan and Oven: Grease a 2-quart baking dish and preheat the oven to 350 F.

Cook the Pasta: Cook the pasta in boiling salted water following the package directions, drain it, and set aside.

Cook the Bacon: Meanwhile, cook the diced bacon in a large sauté pan or saucepan over medium heat until crisp; transfer to paper towels to drain.

Make the Sauce: Add the minced garlic to the drippings in the skillet and cook for 1 minute. Add heavy cream and cream cheese and whisk for 1 to 2 minutes or until the cream cheese is melted and the sauce mixture is smooth. Remove from the heat.

Finish the Dish: Add the Parmesan cheese, ranch dressing mix, pepper, and chicken broth; stir to blend. Add the drained pasta, chicken, and 1/2 cup of mozzarella cheese. Stir until the ingredients are all well distributed and transfer to the prepared baking pan. Top with the bacon and the remaining mozzarella cheese.
