Cook the Bacon: Place bacon slices in a large deep skillet over medium heat. Cook until crisp, turning as needed. Transfer bacon to a plate and chop once cooled. Leave a small amount of bacon fat in the pan.
Brown the Chicken: Add chicken pieces to the skillet. Cook while stirring until lightly golden and cooked through. Remove chicken and set aside with the bacon.
Build the Base: Pour chicken broth into the same skillet. Bring it to a gentle boil, then add penne. Stir often and cook until the pasta turns tender and most of the liquid absorbs.
Create the Sauce: Lower the heat. Add cream cheese and ranch seasoning. Stir slowly until the sauce turns smooth and creamy.
Bring It Together: Return chicken and bacon to the pan. Sprinkle in cheddar cheese and stir until melted and well mixed with the pasta.
Finish and Rest: Remove the skillet from heat. Let the pasta sit for a few minutes so the sauce thickens and coats every bite.
Garnish and Serve: Top with chopped parsley before serving for a fresh touch.
