The brilliance of this casserole lies in its simplicity and versatility. It uses pantry-friendly ingredients, doesn’t require much prep work, and bakes beautifully to golden perfection.

You can even prep it the night before and pop it in the oven the next day—perfect for busy mornings or entertaining guests.

What You’ll Need for This Hashbrown Chicken Casserole

Let’s break down the ingredients:

2 cups cooked, shredded or diced chicken – You can use rotisserie chicken, baked chicken breasts, or even leftover grilled chicken.

1 bag (about 20 oz) frozen hashbrown potatoes – Thawed before mixing. You can use cubed or shredded style based on your texture preference.

1 can cream of chicken soup – Adds that rich, creamy base.

1 cup sour cream – Gives the casserole a tangy balance and extra creaminess.

1½ cups shredded cheddar cheese – Sharp cheddar works great, but feel free to mix in Monterey Jack or mozzarella.

½ cup chopped onions – Optional, but highly recommended for extra flavor.

Salt, pepper, garlic powder to taste

1/4 cup melted butter – For richness and a beautifully golden top.

Optional toppings: crushed Ritz crackers, cornflakes, or extra cheese for the topping.

How to Make Hashbrown Chicken Casserole

Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.

Combine the ingredients: In a large mixing bowl, stir together the cream of chicken soup, sour cream, half the shredded cheese, onions, seasonings, and melted butter.

Add the chicken and hashbrowns: Gently fold in the cooked chicken and thawed hashbrowns until everything is well coated.

Transfer to baking dish: Pour the mixture into your greased dish and spread evenly.

Top it off: Sprinkle the remaining cheese (and crushed crackers or cornflakes if using) on top for that perfect crunchy, cheesy crust.

Bake uncovered for about 45 minutes or until the top is bubbly and golden brown.

Let it rest for a few minutes before serving so it sets just right.

Tips + Tricks for Recipe Success

Short on time? Use pre-cooked chicken like rotisserie to speed things up.

Like it spicy? Add a can of diced green chiles or some hot sauce for a little kick.

Prefer a crunchier top? Mix the topping crackers with a tablespoon of melted butter before sprinkling over the casserole.

Add veggies: You can stir in frozen peas, carrots, or even broccoli to make it a full one-dish meal.

Make it ahead: This dish can be assembled the night before. Just cover and refrigerate. Bake as usual the next day—just add a few extra minutes if baking straight from the fridge.

What to Serve with Hashbrown Chicken Casserole

This casserole is a whole meal on its own, but if you’re planning a spread or want to add a side dish, here are some delicious ideas:

Green salad – Something light and crisp to balance the richness.

Steamed veggies – Broccoli, green beans, or carrots work well.

Fruit salad – For a refreshing, sweet contrast.

Garlic bread – If you’re looking to go all-in on comfort.

Storing and Reheating

One of the best parts of this dish is how well it stores. You can easily make a big batch and enjoy leftovers throughout the week.

In the fridge: Store leftovers in an airtight container for up to 4 days.

To reheat: Microwave individual portions or reheat in the oven at 350°F for about 15–20 minutes until warmed through.

Freezing instructions: Assemble the casserole without baking, wrap tightly, and freeze for up to 3 months. Thaw in the fridge overnight and bake as directed.

Make It Yours – Variations to Try

Don’t be afraid to play around with flavors. This casserole is a great base for creativity.

Buffalo chicken twist: Add buffalo sauce and top with blue cheese crumbles.

Tex-Mex style: Stir in black beans, corn, and taco seasoning, and top with pepper jack cheese.

Ham and cheese: Swap chicken for ham and use Swiss or Gruyere cheese.
