Step by Step Instructions
Step 1: In a large mixing bowl, combine thawed hash brown potatoes with shredded cheddar cheese. Add salt and pepper to taste, and toss until evenly coated. This is the hearty, cheesy base of your casserole.
Step 2: In a saucepan over medium heat, melt the butter. Stir in cream of chicken soup, sour cream, and milk until smooth and creamy. Pour the warm sauce over the potato and cheese mixture, stirring until everything is evenly coated in that rich, velvety sauce.
Step 3: Grease a 9×13-inch baking dish. Spoon the creamy potato mixture into the dish and spread it out evenly with a spatula. Smooth the top so it bakes uniformly and develops that golden, cheesy crust.
Step 4: Sprinkle crushed corn flakes evenly over the top. Drizzle lightly with melted butter to help the topping crisp up beautifully. Bake at 350°F (175°C) for 1 hour, or until golden brown and bubbling around the edges. Let rest for 10 minutes before serving.
Expert Tips
- Thaw your potatoes: Ensures even cooking and prevents watery texture.
- Warm the sauce: Makes it smoother and helps coat the potatoes perfectly.
- Use sharp cheddar: The stronger flavor balances the creamy sauce.
- Add topping last: Keeps the corn flakes crunchy and crisp.
- Rest before serving: Allows the casserole to set for cleaner slices.

Sophia’s Top Tip
- Grate your cheese fresh! Pre-shredded cheese contains anti-caking agents that affect melting. Freshly grated cheddar gives you that silky, creamy texture and rich flavor every time.
