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 it warms up, grab a 9×13-inch baking dish and generously grease it with butter or cooking spray. This step is crucial as it prevents the casserole from sticking, ensuring a beautiful, easy release when it’s done baking.
Step 2: Mix the Base
In a large mixing bowl, combine one can of cream of chicken soup, sour cream, melted butter, and 1.5 cups of shredded cheddar cheese. Use a whisk or spatula to blend these ingredients until the mixture is creamy and smooth, with no lumps remaining. This rich base sets the stage for the comforting flavors you’ll experience in Grandma’s Hash Brown Casserole.
Step 3: Add Flavorful Ingredients
Next, add finely chopped onion, garlic powder, salt, and pepper to the creamy mixture. Stir well to ensure the flavors meld beautifully. By incorporating these seasonings, you create a savory foundation for your casserole, enhancing the overall taste profile with every comforting bite.
Step 4: Incorporate Hash Browns
Gently fold in the frozen shredded hash browns to your mixture without mashing them. It’s essential to ensure the hash browns remain intact to create that perfect texture in Grandma’s Hash Brown Casserole. Aim to combine everything evenly, distributing the creamy mixture throughout the hash browns for consistent flavor.
Step 5: Assemble the Casserole
Carefully spread the hash brown mixture into the greased baking dish. Use a spatula to even out the top, ensuring it’s uniformly layered. Sprinkle the remaining shredded cheese over the top to create a melty, gooey finish. This step makes it visually appealing and promises a delicious cheesy crust when baked.
Step 6: Prepare the Crunchy Topping
In a small bowl, mix crushed cornflakes or buttery crackers with a few tablespoons of melted butter. Stir until the crumbs are well-coated. This mixture will add a delightful crunch on top of your casserole, perfectly contrasting the creamy base and enhancing every mouthful of Grandma’s Hash Brown Casserole.
Step 7: Bake to Perfection
Place the assembled casserole into your preheated oven and bake uncovered for 45–55 minutes. Keep an eye on it as it cooks; you’re looking for a golden-brown top and bubbly edges. The aroma will be irresistible, signaling that your comforting dish is nearly ready to serve.
Step 8: Cool Before Serving
Once baked to perfection, remove Grandma’s Hash Brown Casserole from the oven and allow it to sit for about 10 minutes. This brief resting period is essential for helping the casserole set, making it easier to slice and serve. Its cheesy, creamy interior will beckon everyone to the table!
