Ingredients You’ll Need
What makes Grandma’s Hash Brown Casserole a true classic is its simple, accessible ingredient list. Each one is essential, working together to create that perfect harmony of cheesy goodness and golden crunch. Let’s break down what you’ll need and why:
- Frozen shredded hash browns (30 oz bag, thawed): These form the heart of the casserole, bringing the iconic potato texture and flavor.
- Unsalted butter (1/2 cup, melted): Adds richness and ensures each bite is wonderfully tender and moist.
- Condensed cream of chicken soup (1 can, 10.5 oz): This ingredient binds everything together, bringing creamy flavor and comfort.
- Sour cream (1 cup): Creates tangy undertones, balancing all that richness.
- Chopped yellow onion (1/2 cup): Gives each forkful a burst of savory sweetness and a bit of crunch.
- Shredded sharp cheddar cheese (2 cups): Melts into gooey perfection and adds that crave-worthy cheesy stretch.
- Garlic powder (1/2 teaspoon): Lends a subtle pop of flavor that complements the onion and cheese.
- Salt (1/2 teaspoon): Enhances all the flavors, making each ingredient shine.
- Black pepper (1/4 teaspoon): Just enough for a little gentle warmth without overwhelming the dish.
- Crushed cornflakes or buttery crackers (1 1/2 cups): The iconic crunchy topping that makes every bite memorable.
- Melted butter, for topping (2 tablespoons): Ensures the topping becomes golden and crisp in the oven.
How to Make Grandma’s Hash Brown Casserole
Step 1: Prepare the Baking Dish
Start by preheating your oven to 350°F (175°C). While that’s warming up, grab your favorite 9×13-inch baking dish and give it a light greasing. This ensures that every cheesy, creamy layer of your Grandma’s Hash Brown Casserole comes out of the pan with ease—and minimal sticking!
Step 2: Mix the Casserole Base
In a big mixing bowl, combine the thawed hash browns, 1/2 cup of melted butter, cream of chicken soup, sour cream, chopped onion, sharp cheddar cheese, garlic powder, salt, and black pepper. Stir until everything looks perfectly melded and you start to catch those familiar, inviting smells. This mixture should be creamy, speckled with onion and cheese, and ready to be the ultimate comfort food base.
Step 3: Spread into the Dish
Pour your creamy potato mixture into the prepared baking dish. Use a spatula to gently smooth the top so you get an even layer—this helps ensure even baking and makes for a beautiful golden crust later.
Step 4: Add the Crunchy Topping
In a separate small bowl, mix the crushed cornflakes or buttery crackers with the remaining 2 tablespoons of melted butter. Sprinkle this mixture evenly over your casserole. This is where Grandma’s Hash Brown Casserole gets its iconic, crispy crown—don’t be shy!
Step 5: Bake to Perfection
Slide your casserole into the oven and bake, uncovered, for 45 to 50 minutes. The magic happens as the top turns golden and the edges start to bubble. Let it rest for 5 to 10 minutes when it comes out—this helps the layers set and makes serving neat, cheesy squares much easier.
How to Serve Grandma’s Hash Brown Casserole

Garnishes
The classic appeal of Grandma’s Hash Brown Casserole is its simple, unfussy beauty, but don’t be afraid to sprinkle on some fresh chopped parsley, sliced green onions, or a pinch of extra shredded cheddar just before serving. These little touches add color and a fresh note that complements the deep, rich flavors perfectly.
Side Dishes
This casserole really shines alongside holiday hams, roast chicken, or even a big breakfast spread. Pair it with crisp green beans, a side salad, or buttery dinner rolls for a complete meal that keeps every forkful interesting (and delicious!).
Creative Ways to Present
For special occasions or everyday fun, scoop individual portions into ramekins or muffin tins for pre-portioned servings. Or serve Grandma’s Hash Brown Casserole family-style with a big spoon and let everyone dig in—a guaranteed way to bring big smiles around the table!
Make Ahead and Storage
Storing Leftovers
Leftover Grandma’s Hash Brown Casserole is a real treat. Cover the baking dish tightly with foil or transfer leftovers to an airtight container. Store in the refrigerator for up to 4 days—if it lasts that long!
Freezing
Want to prep ahead? Assemble the casserole (without adding the topping), wrap it well, and freeze for up to 3 months. Add the buttery cornflake or cracker topping just before baking for best results. You can also freeze leftovers, but keep in mind the texture of the potatoes may soften a bit after thawing.
Reheating
To reheat, simply warm covered in a 350°F oven until sizzling hot and heated through (about 20 minutes if thawed, longer if frozen). For a crispier top, uncover for the last 5 minutes. Individual portions can also be microwaved for a quick, comforting snack.
FAQs
Can I make Grandma’s Hash Brown Casserole ahead of time?
Absolutely! Prepare everything but the topping, cover, and refrigerate overnight. When ready to bake, add the topping and bake as directed for fresh flavor and crunch.
What’s the best substitute for cream of chicken soup to make this vegetarian?
Swap the cream of chicken soup for cream of mushroom soup—this keeps the dish creamy and delicious, with earthy undertones that pair beautifully with potatoes and cheese.
Can I use fresh potatoes instead of frozen hash browns?
You can use fresh potatoes by shredding them and squeezing out excess moisture with a clean kitchen towel. The texture will be a bit different but just as delectable!
How do I keep the casserole from getting soggy?
Drain your hash browns well after thawing to remove any extra moisture, and be sure to bake uncovered so excess steam can escape. This keeps the texture wonderfully creamy inside and crisp on top.
Can I add meat or extra veggies?
Definitely! Try adding cooked bacon bits, diced ham, or sautéed bell peppers and mushrooms to the mix for a hearty twist—just fold them in with the hash browns before baking.
