How to Make Grandma’s Hash Brown Casserole Recipe
Step 1: Preheat and Prepare
Start by setting your oven to 350°F (175°C). This temperature ensures a slow, even bake that melds all the flavors together beautifully while creating that golden crust you’ll love. As the oven warms, gather all your ingredients so everything is ready to go.
Step 2: Mix the Magical Base
In a large bowl, combine the thawed hash browns, shredded Cheddar, cream of chicken soup, sour cream, half of the melted butter, chopped onion, salt, and pepper. Stir these until they’re well incorporated. This mixture is where all those creamy, cheesy, and savory flavors blend to create the heart of the casserole.
Step 3: Spread Into the Baking Dish
Transfer the mixture into a 9×13-inch baking dish. Use the back of a spoon or a spatula to spread it evenly so every bite cooks consistently. This even layer is key for the texture and appearance after baking.
Step 4: Add the Crunchy Topping
Sprinkle the crushed cornflakes evenly on top. Then drizzle the remaining melted butter over them—this step is what transforms the topping, giving you that irresistible golden crispiness that contrasts perfectly with the creamy interior.
Step 5: Bake to Perfection
Slide the dish into your preheated oven and bake for 1 hour and 15 minutes. Patience is your friend here as the casserole bubbles up and develops a beautiful golden top—an unmistakable sign that it’s ready to be enjoyed.
Step 6: Cool Slightly and Serve
Once baked, let the casserole rest for a few minutes. This cooling time helps it set, making serving easier and keeping all the layers intact. Then, dig in and enjoy the comforting goodness!
