Ingredients
To make this classic cheesy hashbrown casserole, you’ll need:
- 1 (30-ounce) bag frozen hashbrowns, thawed
(or fresh grated potatoes, squeezed dry) - 1 can (10.5 ounces) cream of chicken soup
(cream of mushroom works for a vegetarian version) - 1 cup sour cream
- 2 cups shredded cheddar cheese, divided
- 4 tablespoons butter, melted
- 1 small onion, finely chopped
- Salt and black pepper, to taste
- Optional topping: 1 cup crushed cornflakes or breadcrumbs
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray to ensure easy serving after baking.
Step 2: Prepare the Creamy Base
In a large bowl, combine the cream of chicken soup, sour cream, melted butter, and chopped onion. Stir until smooth and well blended. This mixture forms the rich, creamy foundation of the casserole.
Step 3: Add the Hashbrowns and Cheese
Add the thawed hashbrowns to the bowl, followed by 1½ cups of shredded cheddar cheese. Season with salt and black pepper. Gently fold everything together until the potatoes are evenly coated, being careful not to mash them.
Step 4: Assemble the Casserole
Transfer the mixture to the prepared baking dish and spread it evenly. Sprinkle the remaining ½ cup of cheese over the top. For added crunch, finish with crushed cornflakes or breadcrumbs. Dot the top with small pieces of butter for extra browning.
Step 5: Bake Until Golden
Bake uncovered for 45–50 minutes, or until the casserole is bubbling around the edges and the top is beautifully golden brown.
Step 6: Rest Before Serving
Remove the casserole from the oven and let it rest for 5–10 minutes. This allows it to set slightly, making it easier to slice while staying creamy inside.
Step 7: Serve and Enjoy
Serve warm as a breakfast centerpiece, a hearty side dish, or a comforting addition to any meal. It pairs perfectly with eggs, roasted meats, or a fresh green salad.
