How to Make Grandma’s Hash Brown Casserole Recipe

Step 1: Prep Your Oven and Baking Dish

Start by preheating your oven to 350°F. Grease a 9×13-inch baking dish to prevent sticking and make sure your masterpiece will bake evenly with a perfect crust.

Step 2: Combine the Main Ingredients

In a large mixing bowl, toss together the thawed hash browns, cream of chicken soup, 1 1/2 cups of the shredded sharp cheddar cheese, sour cream, melted butter, diced onion, salt, and black pepper. Stir everything until it’s thoroughly combined, creating a creamy, cheesy mixture that’s bursting with flavor.

Step 3: Transfer and Top

Spread this delicious mixture evenly into your greased baking dish, making sure the surface is smooth. In a small bowl, mix together the crushed cornflakes with the remaining melted butter for that irresistible crunchy topping. Sprinkle the cornflake mixture all over the casserole and then generously add the last 1/2 cup of shredded cheddar cheese on top.

Step 4: Bake to Perfection

Place the casserole in the oven and bake uncovered for 45 to 50 minutes. You’ll know it’s done when the casserole is bubbly and the top is beautifully golden brown. Let it rest for about 5 minutes before serving to allow the flavors to settle and the casserole to firm up slightly for easier serving.
