Ingredients
  

  • 4 medium russet potatoes
  • 2 cups boneless, skinless chicken breasts
  • 1 cup milk
  • 1/2 cup cream cheese
  • 2 cups shredded cheddar cheese
  • 1 cup sour cream
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 pinch salt
  • 1 pinch black pepper
  • 1 tablespoon butter
  • 1 tablespoon chopped fresh parsley

Instructions
 

  • Preheat your oven to 400°F (200°C) and lightly grease a 9x13-inch baking dish with butter or cooking spray.
  • Parboil the diced potatoes for 5 minutes in salted water until just starting to soften. Drain well; they’ll finish cooking in the casserole and help keep the interior creamy.
  • In a large mixing bowl, combine the milk, cream cheese, sour cream, garlic powder, onion powder, salt, and pepper. Whisk until smooth and well blended.
  • Add the chicken pieces and the parboiled potatoes to the bowl. Stir gently to coat everything in the creamy mixture.
  • Pour the mixture into the prepared baking dish. Sprinkle with the shredded cheddar cheese and dollop a few small spoons of extra cream cheese on top if you like extra creaminess.
  • Bake for 25–30 minutes, or until the potatoes are tender and the cheese topping is golden and bubbling.
  • If you’d like a crisper top, switch the oven to broil for 2–3 minutes at the end, watching carefully to prevent burning.
  • Remove from the oven and let the casserole rest for 5–10 minutes. Garnish with chopped parsley before serving.
