The Complete Hashbrown Casserole Recipe

This recipe serves 8‑10 people. It bakes in a 9×13‑inch dish.

Ingredients

· 1 bag (30 oz / 850g) frozen shredded hash browns (do not thaw completely? Thaw slightly for easier mixing, but not necessary)
· 1 can (10.5 oz / 298g) cream of chicken soup (or cream of mushroom for vegetarian)
· 1 cup (240g) sour cream (full‑fat for best creaminess)
· 2 cups (200g) shredded cheddar cheese (divided – 1½ cups in the casserole, ½ cup on top)
· ½ cup (113g) unsalted butter, melted
· ½ cup finely chopped yellow onion (optional, but adds flavor)
· ½ teaspoon salt
· ¼ teaspoon black pepper
· ½ teaspoon garlic powder (optional)

For the Topping (Optional but Recommended)

· 1 cup crushed cornflakes (or panko breadcrumbs)
· 2 tablespoons melted butter (for tossing with cornflakes)

Equipment

· 9×13‑inch baking dish
· Large mixing bowl
· Spatula

Step‑by‑Step Instructions

Step 1 – Preheat and Prepare

Preheat your oven to 350°F (175°C). Lightly grease a 9×13‑inch baking dish with butter or cooking spray.

Step 2 – Thaw Hash Browns (Optional)

You can use frozen hash browns directly, but for easier mixing, let them sit at room temperature for 15‑20 minutes to thaw slightly. Do not microwave – they will become mushy.

Step 3 – Mix the Base

In a large bowl, combine the cream of chicken soup, sour cream, 1½ cups of shredded cheddar cheese, melted butter, chopped onion (if using), salt, pepper, and garlic powder. Stir until well blended.

Step 4 – Add Hash Browns

Add the frozen (or partially thawed) hash browns to the bowl. Mix well until all the potatoes are evenly coated with the creamy mixture.

Step 5 – Transfer to Baking Dish

Spread the mixture evenly into the prepared baking dish. Smooth the top with a spatula.

Step 6 – Add Topping

Sprinkle the remaining ½ cup of shredded cheddar cheese over the top. For extra crunch, mix crushed cornflakes with 2 tablespoons of melted butter and sprinkle over the cheese.

Step 7 – Bake

Bake uncovered at 350°F for 45‑55 minutes, until the casserole is hot and bubbly and the top is golden brown. If the top browns too quickly, loosely cover with foil for the last 15 minutes.

Step 8 – Rest and Serve

Let the casserole rest for 10 minutes before serving. This allows it to set slightly for cleaner slices. Serve warm.

Pro Tips for the Best Hashbrown Casserole

Use Full‑Fat Dairy

Low‑fat sour cream and reduced‑fat cheese contain more water and may make the casserole watery. Full‑fat products give the creamiest, richest result.

Do Not Overmix

Overmixing can break the shredded potatoes into smaller pieces, making the casserole mushy. Gently fold until combined.

Thaw Hash Browns Properly

If you use frozen hash browns directly from the freezer, they will release water as they thaw during baking, potentially making the casserole watery. Thaw them slightly in the refrigerator or on the counter for 20 minutes, then pat dry with paper towels.

Add a Crunchy Topping

Cornflakes or panko breadcrumbs tossed with melted butter add a wonderful crispy contrast to the creamy interior. This is the secret to an irresistible top layer.

Make It a Meal

Add cooked crumbled sausage, diced ham, or crispy bacon to the mixture for a heartier casserole. Or stir in sautéed mushrooms, bell peppers, or spinach.

For a Cheesy Crust

Add an extra layer of cheese on top during the last 10 minutes of baking and broil for 1‑2 minutes until bubbly and golden.

Let It Rest

Letting the casserole rest after baking allows the starches to set, making it easier to slice and serve.
