Preheat your oven to 350°F (175°C) and gather a large baking dish.
Cook the penne pasta according to package instructions until al dente, then drain and set aside.
In a large mixing bowl, combine the shredded chicken, cream cheese, ranch dressing, chicken broth, garlic powder, onion powder, salt, and pepper. Mix until fully blended.
Stir in the cooked penne pasta and thawed broccoli florets until evenly coated with the creamy mixture.
Pour the mixture into the prepared baking dish and spread it out evenly.
Top the mixture with shredded cheddar cheese and crispy fried onions.
Bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly, and the top is golden brown.
Remove from the oven and let it cool for a few minutes before slicing.
Garnish with freshly chopped parsley before serving.
Notes
Let the dish cool for a few minutes before slicing for easier serving.
