Step‑by‑Step Instructions for Grandma’s Hash Brown Casserole

Step 1: Preheat the Oven and Prepare the Dish
Begin by preheating your oven to 350°F (175°C). While that heats up, take a 9×13-inch baking dish and generously grease it with cooking spray or a bit of melted butter. This crucial step ensures your Grandma’s Hash Brown Casserole won’t stick, allowing for easy serving and clean-up later.

Step 2: Mix the Creamy Base
In a large mixing bowl, combine one can of cream of chicken soup, one cup of sour cream, and half a cup of melted butter. Stir the mixture thoroughly until it becomes creamy and smooth. This flavorful base will infuse the entire casserole with richness and depth as it bakes.

Step 3: Add Flavors and Cheese
Next, fold in the finely chopped onion, one teaspoon of garlic powder, half of the shredded cheddar cheese, and a sprinkle of salt and black pepper. Mix everything well to distribute the flavors evenly throughout the creamy base; it will create an aromatic foundation for your Grandma’s Hash Brown Casserole.

Step 4: Incorporate the Hash Browns
Gently fold in the frozen shredded hash browns, ensuring they are evenly coated with the creamy mixture. It’s important to break any clumps in the hash browns before adding them, so you get a nice, uniform texture. This step ensures every bite of your casserole is filled with those delightful flavors.

Step 5: Transfer to the Baking Dish
Carefully pour the hash brown mixture into your prepared baking dish. Using a spatula, smooth the top to create an even layer. This step is essential for even cooking and browning. Now, your Grandma’s Hash Brown Casserole is ready to go into the oven!

Step 6: Prepare the Topping
For a delicious crunch, mix together crushed cornflakes (or buttery crackers) with a tablespoon of melted butter. Sprinkle this mixture evenly over the top of the casserole. This optional step adds an irresistible texture that contrasts beautifully with the creamy filling underneath.

Step 7: Bake the Casserole
Slide the casserole into your preheated oven and bake uncovered for 45-55 minutes. You’ll know it’s done when the top is golden brown and bubbly, with crispy edges that promise a delightful crunch. The kitchen will fill with a comforting aroma as it cooks, making it even harder to wait!

Step 8: Let it Rest
Once baked, remove the casserole from the oven and let it rest for 10 minutes. This allows the dish to set properly, making it easier to cut into pieces for serving. The rest time also enhances the flavors, giving your Grandma’s Hash Brown Casserole that perfect, savory richness.

Step 9: Garnish and Serve
If desired, sprinkle some fresh parsley or chopped green onions on top for a burst of color and added freshness. Now, gather your friends and family around to enjoy this warm and comforting Grandma’s Hash Brown Casserole—it’s bound to be a hit!
