Ingredients for Cheesy Chicken Hashbrown Casserole

Here’s everything you’ll need to make this creamy, cheesy casserole that’s guaranteed to impress:

  • 3 cups cooked chicken, shredded or diced (rotisserie chicken works beautifully)
  • 1 (30–32 oz) bag frozen shredded hash browns, thawed*
  • 1 (10.5 oz) can condensed cream of chicken soup
  • 1 (8 oz) container sour cream (or Greek yogurt for a lighter twist)
  • 1½ cups shredded cheddar cheese, divided
  • ½ cup milk or chicken broth
  • ½ cup (1 stick) butter, melted, divided
  • 1 small onion, finely diced
  • 2 cloves garlic, minced
  • 1 teaspoon garlic powder
  • ½ teaspoon black pepper
  • Optional topping: 1 cup crushed cornflakes, crackers, or French fried onions

Tip: Be sure to thaw the hash browns completely before baking. Frozen hash browns will make the casserole watery and increase baking time.

How to Make Cheesy Chicken Hashbrown Casserole

Follow these easy steps to create a creamy, cheesy casserole that’s golden brown and bubbling with flavor.

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray to prevent sticking and make cleanup easier.

Step 2: Sauté the Aromatics

In a small skillet, melt 2 tablespoons of butter over medium heat. Add the diced onion and cook for about 5 minutes until softened and translucent.
Add minced garlic and cook for 1 more minute until fragrant.
This simple step infuses the casserole with rich, savory flavor.

Step 3: Mix the Filling

In a large mixing bowl, combine:

  • Thawed hash browns
  • Cooked chicken
  • Cream of chicken soup
  • Sour cream
  • 1 cup of cheddar cheese
  • Milk or chicken broth
  • Remaining melted butter
  • Sautéed onion and garlic
  • Garlic powder and black pepper

Stir everything together until evenly coated. The mixture should be creamy but not runny.

Step 4: Assemble the Casserole

Pour the mixture into the prepared baking dish and spread it evenly.
Sprinkle the remaining ½ cup of cheddar cheese evenly across the top.

If you love a bit of crunch, prepare your topping:
Mix 1 cup crushed cornflakes or crackers with a small drizzle of melted butter, then sprinkle over the cheese layer.

Step 5: Bake Until Golden and Bubbly

Bake uncovered in the preheated oven for 45–50 minutes, or until the top is golden brown and the casserole is bubbling around the edges.
If the top starts to brown too quickly, cover it loosely with foil halfway through baking.

Step 6: Rest and Serve

Remove the casserole from the oven and let it rest for 5–10 minutes before serving.
This helps the mixture set slightly and makes it easier to scoop out clean portions.

Serve warm and enjoy the gooey, cheesy perfection!

Tips for Success

  • Always thaw your hash browns. Baking with frozen potatoes will result in uneven cooking and excess moisture.
  • Use rotisserie chicken for convenience and maximum flavor.
  • Add veggies like peas, carrots, or broccoli to make it heartier.
  • Want it spicy? Add diced green chiles or pickled jalapeños for a little kick.
  • Change up the cheese. Mix in Colby Jack, Pepper Jack, or Monterey Jack for extra flavor.
  • Top it off. A buttery cornflake or cracker topping adds crunch that perfectly complements the creamy filling.
