Step‑by‑Step Instructions for Grandma’s Hash Brown Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms, grease a 9×13-inch baking dish with butter or cooking spray, ensuring an easy release for your delicious hash brown casserole once baked.
Step 2: Mix the Base
In a large mixing bowl, combine the cream of chicken soup, sour cream, and melted butter. Add in the finely chopped onion, 1½ cups of shredded cheddar cheese, garlic powder, salt, and pepper. Stir this mixture until it’s smooth and well-blended, creating a luscious base for Grandma’s Hash Brown Casserole.
Step 3: Add Hash Browns
Carefully fold in the frozen shredded hash browns into the creamy mixture. Make sure to preserve the texture of the hash browns as you gently combine them until they’re evenly coated, infusing every bite with that comforting, creamy goodness.
