This easy hash brown casserole is a comforting dinner side dish made with thawed frozen shredded potatoes, condensed cream of chicken soup, sour cream, melted butter, onion, and plenty of cheddar cheese. Combine the ingredients, spread them into a greased 9-by-13-inch baking dish, and bake uncovered at 350°F (175°C) for 45–50 minutes.
The finished casserole is creamy in the center, savory from the onion and cheddar, and golden around the edges. Add the optional buttered cornflake topping for a crisp contrast, then let the dish stand for 5–10 minutes so it slices and serves neatly.

There is a reason creamy hash brown casseroles appear at family dinners, holiday tables, and casual potlucks: they are simple to assemble and reliably comforting. Frozen shredded potatoes save preparation time, while sour cream, soup, butter, and cheddar create a rich sauce that coats every strand.
This recipe also serves 10–12 people, making it practical when you need a generous side dish. The casserole is satisfying enough for dinner alongside a green salad, roasted vegetables, or a simple protein.
The optional cornflake topping adds a delicate crunch without changing the soft, cheesy interior. If you prefer a simpler finish, use only the remaining cheddar and let it melt into a golden blanket.
For another cozy dish to place on the table, pair this casserole with a comforting turkey meatball casserole. The creamy potatoes and tender meatballs make a hearty combination.
Ingredients You’ll Need
The ingredient list is short, familiar, and easy to find. Measure everything before mixing because the casserole comes together quickly once the potatoes are thawed.
- One 30-ounce package of frozen shredded hash brown potatoes, thawed.
- One 10.5- to 10.75-ounce can of condensed cream of chicken soup, used undiluted.
- Two cups of sour cream for a creamy, lightly tangy sauce.
- One-half cup melted butter for richness and moisture.
- One-half cup finely chopped onion for savory flavor.
- Two cups shredded cheddar cheese, divided between the mixture and the top.
- One teaspoon salt and one-quarter teaspoon black pepper.
- For the optional topping, two cups lightly crushed cornflakes mixed with one-quarter cup melted butter.
When possible, shred cheddar from a block. It generally melts more smoothly than pre-shredded cheese and gives the top a pleasantly creamy texture.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C), then grease a 9-by-13-inch casserole dish. A light coating of butter or cooking spray helps the creamy potatoes release more easily when served.
Step 2: Thaw the frozen shredded hash browns completely. Drain them well or blot them with clean paper towels to remove excess moisture, since wet potatoes can make the casserole watery and slow the center from cooking evenly.
Step 3: Add the condensed cream of chicken soup, sour cream, one-half cup melted butter, chopped onion, salt, black pepper, and 1 1/2 cups of the shredded cheddar to a large bowl. Stir until the sauce looks evenly combined and the cheese is distributed throughout.
Step 4: Fold the thawed potatoes into the bowl rather than stirring aggressively. Work gently but thoroughly until every shred is coated with the creamy mixture, which helps the finished casserole remain moist from edge to edge.
Step 5: Spread the potato mixture into the prepared baking dish and smooth the surface. Sprinkle the remaining one-half cup cheddar over the top, making sure to reach the corners.
Step 6: For the optional crunchy topping, lightly crush the cornflakes and mix them with one-quarter cup melted butter. Scatter the mixture over the cheese in an even layer, or leave it off for a softer, cheese-forward finish.
Step 7: Bake uncovered for 45–50 minutes. The casserole is ready when it is hot and bubbling in the center and the top is golden.
Step 8: Remove the dish from the oven and let it stand for 5–10 minutes before serving. This brief rest allows the creamy filling to settle, so each spoonful holds together instead of spreading across the plate.
Pro Tips for the Best Casserole
Thawing and draining the potatoes is the most important preparation detail. Excess ice and water can dilute the sauce, create a loose texture, and leave the middle less evenly cooked.
Do not dilute the condensed soup. It is designed to be added directly to the sour cream and butter mixture, where it supplies concentrated savory flavor and helps bind the potatoes.
Keep the casserole uncovered while it bakes. This allows the cheddar and optional cornflake topping to brown, while the creamy filling becomes hot and bubbling.
For clean serving portions, use a wide spoon or spatula after the casserole has rested. The first scoop may be slightly softer than later portions, particularly if the dish is served immediately.

Make-Ahead, Storage, and Reheating
To prepare this casserole ahead of time, assemble the potato mixture in the greased baking dish, add the cheese and optional topping, cover it, and refrigerate for up to 24 hours. Keep it chilled until you are ready to bake.
When baking the casserole directly from the refrigerator, add approximately 10–15 minutes to the stated 45–50 minute baking time. Check for a hot, bubbling center and a golden surface rather than relying only on the clock.
For the best texture, leftovers should be covered and refrigerated promptly. Reheat individual portions until hot, or warm a larger amount in an oven-safe dish until heated through.
This casserole is especially useful when entertaining because the prep can be finished before guests arrive. While it bakes, you can arrange a salad, warm another side, or set out easy Instant Pot appetizers for the first course.
What to Serve with Hash Brown Casserole
Serve this dish as a side with roasted chicken, baked ham, turkey, or grilled sausages. Its creamy potatoes are also a natural match for crisp green vegetables such as steamed broccoli, green beans, or a fresh salad.
For a balanced dinner plate, combine one generous spoonful of casserole with a protein and something bright or crunchy. The optional cornflake topping is particularly good with tender meats because it adds texture to an otherwise soft meal.
You can also serve smaller portions at brunch or a casual buffet. The familiar flavors appeal to children and adults, and the 9-by-13-inch dish makes it easy to feed a crowd.

Remember to drain the potatoes well, use the soup undiluted, and bake the casserole uncovered at 350°F (175°C) for 45–50 minutes. A short 5–10 minute rest makes the bubbling filling easier to serve and gives the flavors time to settle.
