Preparation

  • Preheat your oven to 350°F (175°C).
  • Shred the rotisserie chicken, removing any skin and bones.
  • Gather all ingredients and have them ready on your countertop.

Cooking

  • In a large mixing bowl, combine the shredded chicken, frozen hash browns, cheddar cheese, sour cream, and cream of chicken soup.
  • Add the onion powder, garlic powder, salt, and pepper, mixing everything until well combined.
  • Transfer the mixture into a greased 9×13 inch baking dish, spreading it evenly.
  • Bake in the preheated oven for 45-55 minutes, or until the top is golden and the casserole is bubbling.

  • Sprinkle with optional chopped green onions for freshness before serving.
  • Cut into squares and serve warm, perhaps with a side salad for balance.

Notes

For a crispy top, broil the casserole for the last few minutes of cooking. Use a mix of cheese varieties to enhance flavor—think sharp cheddar and Monterey Jack. This casserole stores beautifully. Make it ahead and reheat for quick dinners. Substitute Greek yogurt for sour cream for a protein boost. Use fresh herbs like parsley or dill to elevate the flavor profile.
