Ingredients You’ll Need

The beauty of this Grandma’s Hash Brown Casserole Recipe lies in its simplicity: a handful of staple ingredients that combine effortlessly to create something extraordinary.

• Frozen shredded hash browns (30 oz): The hearty base of the casserole, providing soft, tender potato goodness.
• Cream of chicken soup (10.5 oz): Adds creamy richness and savory depth, binding everything together.
• Sour cream (1 cup): Contributes tanginess and smooth texture, keeping the casserole moist and flavorful.
• Shredded cheddar cheese (2 cups, divided): Sharp and velvety cheese for luscious savoriness inside and melty topping.
• Melted butter (½ cup + 3 tbsp): Infuses buttery richness throughout, and crisps the topping beautifully.
• Finely chopped onion (½ cup): Adds a gentle, savory crunch and bright vegetal flavor.
• Garlic powder (½ tsp): Boosts savory aroma and depth without overpowering.
• Salt (½ tsp) & black pepper (¼ tsp): Season the dish perfectly, balancing all flavors.
• Crushed cornflakes or buttery crackers (1½ cups): Creates a crunchy, golden topping that’s simply irresistible.

Ingredient Substitutions & Tips

• Cream of chicken soup: Use cream of mushroom or cream of celery for a vegetarian twist or milder flavor.

How to Make Grandma’s Hash Brown Casserole Recipe

Step 1: Prepare Your Oven and Dish

Preheat your oven to a cozy 350°F (175°C) to get it nice and ready for baking. Lightly grease a 9×13-inch baking dish—this prevents sticking while keeping every bite intact.

💡 Pro Tip: Using cooking spray or butter here makes cleanup so much easier later!

Step 2: Mix the Creamy Base

In a large bowl, stir together the cream of chicken soup, sour cream, ½ cup melted butter, 1½ cups shredded cheddar cheese, finely chopped onion, garlic powder, salt, and pepper until smooth and luscious.

💡 Pro Tip: Mix gently but thoroughly so you get one harmonious creamy mixture—no lumps allowed!

Step 3: Fold in the Hash Browns

Now, gently fold the thawed, shredded hash browns into the creamy base. This is where the magic happens—each potato strand gets coated in that rich, cheesy goodness.

💡 Pro Tip: Be gentle to avoid mashing the potatoes, keeping that lovely shredded texture.

Step 4: Assemble in the Baking Dish

Spread the mixture evenly into your prepared dish, smoothing the top with a spatula. Sprinkle the remaining ½ cup shredded cheddar cheese evenly over the top to add ooey-gooey cheesy layers.

💡 Pro Tip: Press the mixture slightly to compact it for a neater slice when serving.

Step 5: Prepare the Crunchy Topping

In a small bowl, combine crushed cornflakes with 3 tablespoons melted butter until well-coated. Sprinkle this buttery, crunchy topping evenly over the cheesy layer—this is going to bake up into golden perfection!

💡 Pro Tip: You can swap cornflakes for buttery crackers for a deliciously different crunch.

Step 6: Bake Until Bubbling and Golden

Place your casserole in the oven uncovered and bake for 45 to 50 minutes, or until the top is beautifully golden brown and the dish is bubbling with irresistible warmth.

💡 Pro Tip: Keep an eye on the topping in the last 10 minutes to avoid burning—cover loosely with foil if it browns too quickly.

Step 7: Cool and Serve

Once baked, allow your casserole to rest for a few minutes before serving. This sets the layers, making each slice clean and satisfying.

💡 Pro Tip: Letting it cool also lets all those flavors meld into total comfort food bliss.

Common Mistakes to Avoid

Learn from these common pitfalls to make the best Grandma’s Hash Brown Casserole Recipe every time:

• Using frozen hash browns without thawing: Leads to soggy casserole due to excess water content.
• Skipping the butter in the topping: Results in a dull, crunchy layer instead of a golden, buttery crust.
• Overmixing the potatoes: Can cause a mushy texture instead of tender shredded bites.
• Baking at too high a temperature: May brown the topping before the center cooks through.
• Not seasoning properly: Makes the casserole bland — salt and garlic powder really bring out the flavors.
• Serving too hot: Cuts don’t hold well and flavors don’t settle if you rush to serve.
