Cook Pasta: Boil penne in salted water according to package directions. Drain and set aside.
Sauté Chicken (if not pre-cooked): In a skillet, heat olive oil over medium heat. Add diced chicken, season with salt and pepper, and cook until golden and fully done. Shred the chicken.
Make Sauce: In a large pan, combine chicken broth, cream cheese, and ranch seasoning. Cook over medium heat, whisking until smooth.
Add Cream & Cheese: Pour in the heavy cream and bring to a light simmer. Stir in shredded cheddar cheese until melted and creamy.
Combine All: Add cooked penne, shredded chicken, and crumbled bacon to the sauce. Toss until everything is well coated.
Bake (Optional): For an extra cheesy finish, transfer to a baking dish, top with more cheddar, and bake at 180°C for 10 minutes.
Serve: Let rest for 5 minutes, garnish with parsley, and serve hot.
