Step‑by‑Step Instructions for Cheesy Hash Brown Casserole
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). While the oven warms up, grab a 9×13-inch baking dish and generously spray it with non-stick cooking spray, ensuring that every corner is covered. This will help the casserole release easily once it’s cooked, giving you a beautiful presentation.
Step 2: Make the Cream Soup
In a medium saucepan over medium heat, combine reduced-sodium chicken broth, milk, and all-purpose flour. Whisk them together until smooth, then bring the mixture to a gentle boil while stirring constantly. Once it thickens, reduce the heat and let it simmer for about 3-5 minutes until creamy, creating a rich homemade soup base for your hash brown casserole.
Step 3: Mix the Casserole Ingredients
In a large mixing bowl, combine thawed frozen hash browns, shredded cheddar cheese (remember to set some aside for topping), sour cream, melted butter, the creamy soup you just made, garlic powder, salt, and pepper. Stir until all the ingredients are thoroughly blended, and the hash browns are evenly coated with the cheesy mixture, ensuring a delightful harmony of flavors.
Step 4: Transfer to Baking Dish
Carefully spoon the hash brown mixture into your prepared baking dish. Spread it evenly across the bottom, pressing it gently to create a uniform layer. Once spread, sprinkle the reserved cheddar cheese over the top, which will melt and create a deliciously gooey layer in your Cheesy Hash Brown Casserole.
Step 5: Prepare the Corn Flake Topping
In a small bowl, combine the crushed corn flakes with melted butter, mixing well to ensure the flakes are coated. This will enhance the crunch and flavor of the topping. Evenly sprinkle this mixture over the casserole, making sure to cover all areas for maximum crunch in every bite.
Step 6: Bake to Perfection
Place the baking dish in the preheated oven and bake for about 45 minutes, or until the top is golden brown and crispy. You’ll know it’s ready when the edges are bubbling, and the casserole has a delightful, inviting aroma. This final step transforms your mixture into a mouthwatering, hearty dish perfect for any gathering.

Make Ahead Options
These Cheesy Hash Brown Casserole with Corn Flake Topping is an ideal dish for busy home cooks looking to save time without sacrificing flavor! You can prepare the hash brown mixture up to 24 hours in advance; simply combine all the ingredients and store it in the refrigerator in an airtight container. To maintain freshness, don’t add the corn flake topping until you’re ready to bake. When you’re set to serve, just sprinkle the topping over the casserole and pop it in the oven for about 45 minutes. This ensures every bite is just as delicious and comforting as when freshly made, giving you more quality time with family or friends!

Hash Brown Casserole Recipe FAQs
What should I look for when selecting frozen hash browns?
When choosing frozen hash browns, ensure they are fully thawed and free of clumps for even baking. Look for bags labeled “shredded” or “chunked” and avoid those with dark spots or an off smell, as these can indicate freezer burn or poor quality.
How long can I store leftover hash brown casserole in the refrigerator?
You can keep leftover hash brown casserole in an airtight container for up to 3-5 days. Make sure to let the casserole cool to room temperature before sealing it, which helps maintain its flavor and texture.
Can I freeze hash brown casserole after it’s been baked?
Absolutely! You can freeze leftover casserole for up to 2-3 months. To do this, first let it cool completely, then wrap it tightly in plastic wrap and aluminum foil to prevent freezer burn. Thaw it overnight in the fridge prior to reheating.
How do I reheat frozen hash brown casserole?
To reheat your frozen hash brown casserole, preheat your oven to 350°F (175°C). Remove the cover and place it in the oven for about 30-40 minutes or until heated through. If it’s been thawed, you can reheat it for about 20-25 minutes. Consider checking it mid-way to ensure it doesn’t over-brown.

Additionally, Greek yogurt can substitute for sour cream for a lighter option. Just ensure that any alternative ingredients you use complement the overall flavors.
What if my hash brown casserole turns out watery?
If your casserole ends up watery, it may be due to excess moisture from the hash browns or not enough thickening from the flour. To avoid this, ensure that your hash browns are well-thawed and pat them dry if they feel too wet before mixing. If it still turns out watery, baking it a little longer can help evaporate some of the moisture and improve texture.
