Ingredients

To serve 8, you’ll need:

• 20 oz frozen hashbrowns
• 2 cups shredded cheddar cheese
• 1 tsp salt
• 1 tsp pepper
• 2 cups sour cream
• 10.5 oz can of cream of chicken soup (or homemade equivalent)
• ½ cup milk
• 1 lb shredded cooked chicken (leftover or rotisserie works great)
• 2 cups crushed corn flakes
• 4 tbsp melted butter

Optional Add-Ins: diced onions, garlic powder, green onions, chopped cooked bacon, or jalapeños for a little heat.

Kitchen Tools You’ll Need

• Large mixing bowl
• 9×13 baking dish
• Measuring cups and spoons
• Small bowl (for topping)
• Spatula or large spoon

How to Make Chicken Hashbrown Casserole

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Lightly grease a 9×13 baking dish with butter or cooking spray.

Step 2: Mix the Base

In a large bowl, combine the salt, pepper, sour cream, cream of chicken soup, and milk. Stir until smooth.

Step 3: Add the Chicken, Cheese, and Hashbrowns

Fold in the shredded chicken, cheddar cheese, and frozen hashbrowns. Mix until everything is evenly coated in the creamy base.

Step 4: Transfer to Baking Dish

Spoon the mixture into your prepared baking dish and spread it out evenly.

Step 5: Prepare the Topping

In a separate small bowl, combine the crushed corn flakes and melted butter. Mix until the flakes are well coated.

Step 6: Add the Crunch

Sprinkle the buttery cornflake topping evenly over the top of the casserole.

Step 7: Bake

Bake uncovered for about 1 hour, or until the top is golden and bubbly and the edges are crisp.

Step 8: Cool Slightly Before Serving

Let the casserole rest for 5–10 minutes before serving. This helps the layers set and makes it easier to slice and serve.

Recipe Tips and Flavor Ideas

• Make It Spicy: Stir in a pinch of cayenne or chopped jalapeños for heat.
• Extra Creamy: Add 4 oz cream cheese to the mix for a richer texture.
• Swap the Soup: Use cream of mushroom or celery for a different flavor profile.
• Vegetarian Option: Omit the chicken and add sautéed mushrooms or broccoli instead.
• Top It Off: Garnish with fresh chopped parsley or green onions for color and a burst of freshness.

This recipe is incredibly forgiving, so don’t be afraid to tweak it based on what you have on hand.

Serving Suggestions

This casserole is a complete meal on its own, but it also pairs beautifully with:

• A crisp green salad with vinaigrette
• Roasted vegetables or steamed green beans
• Buttermilk biscuits or garlic bread
• Fresh fruit for a light finish

It’s perfect for brunch, lunch, dinner, or even a hearty breakfast. Leftovers reheat well and make a great lunchbox option, too!

How to Store and Reheat

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

Freezer:
You can freeze the unbaked casserole (without the topping) for up to 3 months. When ready to bake, thaw overnight in the fridge, add the topping, and bake as directed.

Reheating:
Reheat individual portions in the microwave or warm the whole casserole in a 350°F oven until heated through. Add a fresh layer of topping before reheating for extra crunch.
