Grandma’s Hash Brown Casserole Ingredients
For the Casserole
• Frozen Shredded Hash Browns – the star of our dish; no need to thaw, just break up any clumps.
• Cream of Chicken Soup – adds a rich creaminess; substitute with cream of mushroom or celery for a vegetarian option.
• Sour Cream – provides tang and a creamy texture; opt for Greek yogurt for a lighter twist.
• Cheddar Cheese – for that classic cheesy flavor; freshly shredded melts better, but you can mix it up with Colby Jack.
• Butter – essential for binding and flavor; use salted or unsalted depending on preference.
• Chopped Onion – enhances depth; can be sautéed for sweetness or used raw for more kick.
• Salt and Pepper – to taste; remember to adjust due to the saltiness from cheese and soup.
For the Topping
• Crushed Cornflakes (optional) – for a spectacular crunchy topping; buttery crackers or breadcrumbs work just as well!
With these ingredients ready to go, you’re one step closer to creating unforgettable Grandma’s Hash Brown Casserole that will be a crowd-pleaser at your next gathering!
Step‑by‑Step Instructions for Grandma’s Hash Brown Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it heats, grab a 9×13-inch baking dish and generously grease it with butter or non-stick spray to ensure easy serving later. This golden-brown casserole will be bubbling away soon, so get ready for that comforting aroma to fill your kitchen!
Step 2: Mix the Creamy Base
In a large mixing bowl, blend together one can of cream of chicken soup, one cup of sour cream, and half a cup of melted butter until smooth and creamy. This mixture forms the luscious backbone of Grandma’s Hash Brown Casserole, infusing each bite with rich flavor.
Step 3: Add Flavorful Ingredients
Next, stir in the chopped onion, 1.5 cups of shredded cheddar cheese, and season with salt and pepper to taste. The melted cheese will add delightful gooeyness, while the onion brings depth. Mix well to ensure every ingredient is evenly incorporated, setting the stage for a crowd-pleasing dish.
Step 4: Incorporate the Hash Browns
Now, gently fold in the frozen shredded hash browns to the creamy mixture, making sure each potato strand is coated with that cheesy goodness. You don’t want to overmix, so be gentle yet thorough. This step binds the comfort of the casserole together like Grandma would!
Step 5: Spread in Baking Dish
Transfer the mixture into the prepared baking dish, using a spatula to smooth the top into an even layer. This ensures that Grandma’s Hash Brown Casserole bakes evenly. As you do this, envision the golden crust that’s about to emerge in the oven, enticing everyone’s taste buds!
Step 6: Add the Crunchy Topping
For the finishing touch, in a small bowl, combine crushed cornflakes with a tablespoon of melted butter until evenly coated. Sprinkle this crunchy blend evenly over the top of your casserole. This topping will become beautifully crisp and golden-brown, adding texture and flavor!
Step 7: Bake to Golden Perfection
Place the dish in the preheated oven and bake uncovered for 45–55 minutes. You’ll know it’s ready when the edges are crispy and the top is a lovely golden-brown hue, while the interior is bubbly. Keep an eye on it during the last few minutes for that perfect crisp!
Step 8: Cool and Serve
Once done, remove the casserole from the oven and let it cool for 10 minutes before serving. This resting time allows the flavors to meld and the casserole to firm up for easy slicing. Optionally, you can garnish with fresh herbs or an extra sprinkle of cheese for added appeal before digging in!

Expert Tips for Grandma’s Hash Brown Casserole
• Prep Ahead: Assemble your casserole the night before and refrigerate. This makes it easy to bake the next day; just extend baking time by 10-15 minutes.
• Fresh Cheese: Always use freshly shredded cheese for the best melting results. Pre-shredded cheese contains anti-caking agents that can affect texture.
• Taste Often: Season the mixture well with salt and pepper, but taste as you go since the cheese and soup can be salty.
• Topping Alternatives: If you want to mix things up, try using buttery crackers or seasoned breadcrumbs instead of cornflakes for a different crunchy layer.
• Don’t Skip Cooling: Allow the casserole to cool for at least 10 minutes before serving. This helps the casserole set and makes for cleaner slices!
