Instructions
1. Prepping the Base
Preheat your oven to 350°F (175°C) and lightly grease a standard 9×13-inch baking dish with cooking spray or a bit of butter.
2. Mix the Creamy Binding
In a large mixing bowl, combine the condensed cream of chicken soup, sour cream, half of the melted butter (1/4 cup), finely diced onion, garlic powder, salt, and pepper. Whisk until the mixture is completely smooth and uniform. Stir in the shredded cheddar cheese.
3. Fold in the Potatoes
Dump the thawed hash browns into the bowl with the creamy mixture. Using a sturdy spatula, gently fold the potatoes into the sauce until every single shred is thoroughly coated in the cheesy soup base. Transfer the mixture into your prepared baking dish and spread it into an even layer.
4. Create the Crispy Topping
In a separate smaller bowl, toss the crushed cornflakes (or cracker crumbs) with the remaining 1/4 cup of melted butter until the flakes are evenly coated. Sprinkle this mixture uniformly across the top of the potato layer, covering it completely.
5. Bake to Golden Perfection
Pop the casserole into the oven uncovered for 45 to 50 minutes. You’ll know it’s ready when the edges are bubbling vigorously, the potatoes are tender, and the cornflake topping has transformed into a beautiful, crispy golden brown. Let it cool for about 5 to 10 minutes before serving so the casserole sets beautifully.
Make-Ahead and Variations
This dish is a host’s dream because it handles preparation beautifully. You can assemble the entire potato and soup mixture in the baking dish the night before, cover it tightly with foil, and store it in the refrigerator. When you are ready to bake, simply add the fresh buttery cornflake topping right before it goes into the oven (this keeps the cereal from getting soggy overnight) and add about 5 to 10 minutes to the total baking time.
If you want to turn this side dish into a complete one-pan weeknight meal, you can easily fold in two cups of diced leftover ham or shredded rotisserie chicken.
