Ingredients

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 version)

1/2 cup milk
1 lb shredded cooked chicken
2 cups crushed corn flakes

4 tbsp melted butter

Instructions

Step 1: Preheat your oven to 350°F (175°C).
Step 2: In a large bowl, mix together salt, pepper, sour cream, cream of chicken soup, and milk until well combined. Add the shredded chicken, cheddar cheese, and frozen hashbrowns, folding gently to combine.

Step 3: Lightly grease a 9×13-inch baking dish and transfer the mixture evenly into the dish.
Step 4: In a separate bowl, combine the crushed corn flakes with the melted butter. Sprinkle this mixture evenly over the top of the casserole for a crispy topping.
Step 5: Bake uncovered in the preheated oven for about 1 hour, or until the top is golden brown and the casserole is heated through.

Tips & Variations

For extra flavor, add a teaspoon of garlic powder or onion powder to the mixture before baking.
Use leftover rotisserie chicken for convenience and added flavor.
Substitute the corn flakes topping with crushed Ritz crackers or breadcrumbs for a different texture.

If you prefer a spicier dish, stir in some diced jalapeños or chili flakes.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and warm in a 350°F oven for about 20 minutes or until heated through. You can also reheat individual portions in the microwave.

FAQs

Can I use fresh potatoes instead of frozen hashbrowns?

Yes, you can shred fresh potatoes and use them, but be sure to squeeze out excess moisture before adding to prevent sogginess.

Can I make this casserole ahead of time?

Absolutely. Prepare the casserole and refrigerate it uncovered or lightly covered. Bake it within 24 hours, adding a few extra minutes to the baking time if baking from cold.
