Cheesy Baked Potato, Chicken, and Broccoli Casserole

Preheat your oven to 350°F (175°C).

In a large pot, boil the cubed potatoes until tender, about 10 minutes. Drain and set aside.

In a large mixing bowl, combine the cooked chicken, steamed broccoli, 1 1/2 cups of shredded cheddar cheese, sour cream, milk, melted butter, garlic powder, onion powder, salt, and black pepper. Mix until well combined.

Gently fold in the boiled potatoes until everything is evenly mixed.

Transfer the mixture to a greased 9x13 inch baking dish and spread it out evenly.

Sprinkle the remaining 1/2 cup of shredded cheddar cheese over the top.

Bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly.

Let the casserole rest for 5 minutes before serving.
